Definitions
- This invention pertains to lost circulation materials, particularly to lost circulation materials that comprise thermoplastic and cellulosic-fiber blend composites.
- Drilling fluids are used in well drilling operations.
- the drilling fluid which may be a water-, oil-, or synthetic-based formulation, circulates within the well bore, carries cuttings to the surface, lubricates the drilling equipment, and acts as a cooling agent.
- So-called "lost circulation” occurs when drilling fluids or muds enter into a porous or fractured formation, and are lost to the drilling operation rather than returning to the surface for recycling and reuse. Lost circulation is a significant industry problem. It is estimated that lost circulation costs the industry about $800 million per year in the United States alone, and that the lost circulation products could represent as much as an additional $200 million annually. Lost circulation can lead to failures in testing wells, and can also lead to decreased productivity.
- Lost circulation materials have been employed to try to reduce levels of lost circulation. These “lost circulation materials” have included such things as coarse cellulosic fibers, fine cellulosic fibers, coarse nut shells, synthetic graphite, cellulose derivatives, mineral fibers, fine calcium carbonate (e.g., 1 mm in diameter), medium-sized calcium carbonate (e.g., 2 mm in diameter), and coarse calcium carbonate (e.g., 3 mm in diameter).
- Lost circulation materials often include different particle types and sizes to address different sizes of fracture. If part of the material is rigid but compressible or expandable under pressure, the material can perhaps mold itself into the fractures to help seal leaks. Cellulosic fibers alone will often lack the needed rigidity.
- a greater concentration of the material may be required to effectively inhibit lost circulation.
- Inelastic materials such as waste plastics and rubber used in the lost circulation materials typically do not have the swelling/expansion properties that are needed to better plug cracks and fissures.
- Resilient graphitic carbon (RGC) of various sizes has been used in lost circulation compositions due to its resilience, but RGC can be expensive.
- U.S. Patent Application publication no. 2006/0096759 discloses a lost circulation composition with a first portion of particles having a weight mean particle size of less than about 20 microns, a second portion of particles having a weight mean particle size in the range from about 25 microns to about 400 microns, and a third portion of particles having a weight mean particle size in the range of from about 450 microns to about 1,500 microns.
- U.S. Patent No. 4,422,948 discloses a lost circulation material comprising a mixture of flexible flakes, fibers, and granular particles made of shredded paper, mineral wool, and calcium carbonate.
- U.S. Patent No. 7,229,492 discloses a well cement composition comprising a hydraulic cement, water, and inelastic lost circulation material particles made of granulated waste materials such as polyethylene, polystyrene, or polypropylene.
- U.S. Patent No. 3,375,888 discloses a three-component lost circulation material comprising nutshells, shredded carpet, and lacquered regenerated cellulose.
- U.S. Patent No. 3,574,099 discloses the use of nutshells and asbestos fibers as lost circulation material.
- U.S. Patent No. 4,526,240 discloses the use a lost circulation material containing a hydrophilic absorbent composite comprising a fibrous absorbent and a water- swellable hydrophilic polymer absorbent.
- a compacted, fibrous material such as layered tissue or paper laminate, is mechanically shredded to form a loose, soft mass of fibers ("fluff), which is combined with a swellable polymer for lost circulation control.
- U.S. Patent No. 3,629,102 discloses a three-component mixture of coarse nutshells, fine nutshells, and sugar cane fibers as a lost circulation material.
- U.S. Patent No. 4,579,668 describes a two-component lost circulation material derived from discarded wet-cell battery casings.
- the first component is a thermoplastic polymer in a flexible, elongated form
- the second component is a granular thermoset plastic with a specific gravity in the range 1.2-1.4.
- U.S. Patent No. 5,826,669 discloses the use of resilient graphitic materials for fluid loss and lubrication purposes.
- U.S. Patent Application publication no. 2008/0113879 discloses the use of plastic granules (e.g., polypropylene) as lost circulation additives in drilling fluid.
- plastic granules e.g., polypropylene
- U.S. Patent Application No. 2009/0054269 Al discloses the use of what were called "composite particles" containing a cellulosic fiber and a filler as a lost circulation material.
- cellulosic fibers included fibers from trees and plants, sugar beet, sugarcane, citrus pulp, potatoes, grains, peanut hulls, corn cobs, tobacco stems, apple pumice, natural grasses, cotton, and peat.
- fillers included kaolin clay, calcium carbonate, barites, titanium dioxide, and ground thermoset polymer laminates.
- the cellulosic fiber could be paper fiber
- the filler could be a ground laminate containing paper or fabric and melamine resin.
- the novel method employs composite materials as lost circulation materials.
- the materials are economical, and seal fissures and cracks more rapidly, more efficiently, and at higher temperatures than is typical of most commercially-available lost circulation materials.
- the composites employed in the novel method comprise a thermoplastic polymer and cellulosic fibers. It is important that the polymer and fiber are combined into a composite material, and are not just a simple mixture.
- a "composite” is an engineered, solid- phase material made from two or more constituent materials with significantly different physical or chemical properties, in which the constituents remain separate and distinct on a macroscopic level within the finished, solid-phase structure.
- the composites may also include additional components.
- Preferred embodiments comprise extruded blends of cellulosic fibers, a thermoplastic polymer matrix, calcium carbonate, and clay. The calcium carbonate can increase the density of the materials as well as adding rigidity.
- the composites may also include oil and other blending (or bonding) agents to modify performance characteristics (e.g., rigidity, swelling, and lubrication) or material handling properties.
- the thermoplastic cellulosic-fiber blend (TCB) composite may, for example, be made in pellets or in particulate forms of various sizes to suit different fracture sizes (e.g., 1 to 5,000 microns) through extrusion, grinding of extruded materials, and other techniques otherwise known in the art for forming composites.
- the Young's modulus of the particles is preferably from ⁇ 0.5 to -3.0 GPa; more preferably the particles comprise a mixture of particles having a range of Young's moduli throughout the range from ⁇ 0.5 to -10.0 GPa, which imparts a progressive deformability to the mixture to accommodate the opening and closing of fractures under varying conditions. It is preferred that the material only be mixed with water, aqueous mixtures, aqueous slurries, or aqueous muds shortly before being pumped into a well bore as part of the drilling fluid. In the fractured formations, the particles can settle down, absorb water, and swell in size while maintaining rigidity.
- the swelling property helps lock the particles into the fractured formation and seal the fractures against drilling fluid leakage.
- the optional oil component tends to leach out once the material is in contact with water. The leached oil helps reduce the abrasiveness of the material, and makes it suitable for use in drilling lubricants; it may even replace more expensive lubricant materials such as glass beads.
- the composition may optionally be made using plastics having different melting temperatures to suit a variety of different formations.
- the composites have superior properties over the properties of a simple mixture (see Tables 3 and 4 below). Size distribution of lost circulation materials should be tailored to the properties of the particular formation. Use of a composite material allows one more readily to control the size distribution of the particles than with mixtures of the individual components, which in general will vary more unless special efforts are taken with material handling (at increased expense).
- the thermoplastic polymer forms a matrix to bind the other components into composite particles.
- the thermoplastic polymer may be any of the various thermoplastic materials known in the art, virgin or recycled, common or engineering polymer; including by way of example acrylonitrile butadiene styrene (ABS), polymethylmethacrylate (PMMA), acrylonitrile (AN), polytetrafluoroethylene (PTFE), polyvinylidene fluoride (PVDF), nylon 6, nylon 66, polycarbonate (PC), polybutylene terephthalate (PBT), polyethylene terephthalate (PET), polyetheretherketone (PEEK), polyetherimide (PEI), low density polyethylene (LDPE), high density polyethylene (HDPE), polyimide (PI), polyphenylene oxide (PPO), polyphenylene sulfide (PPS), polypropylene (PP), polystyrene (PS), polysulfone (PSO), polyethersulfone (PES), polyvin
- thermoplastic material One function of the thermoplastic material is to provide a matrix material for cellulosic fibers and other additives. For economic and environmental considerations, it is often preferred to use recycled materials such as discarded, HDPE-based motor oil containers. Prior to preparing the composite, it is generally preferred that the thermoplastic be in powder, pellet, or particulate form. If not already in such a form, the recycled polymers may be ground using standard polymer grinders known in the art. Depending on the characteristics of the formation in which the lost circulation material will be used, it will often be preferred to employ a mixture of both "common" plastics (melting temperatures less than 200 0 C) and “engineering plastics” (melting temperature around 250-270 0 C) to extend the useful temperature range of the material. Where more than one type of polymer is employed, they may be mixed as melts, or they may be co-extruded.
- the thermoplastic may comprise from about 10% to about 90% of the total lost circulation material by mass.
- the cellulosic fiber portion of the lost circulation material may comprise any cellulosic materials, including for example fibers or particles from softwood (e.g., southern pine), hardwood (e.g., maple), bamboo, rattan, rice straw, wheat straw, rice husk, bagasse, cotton stalk, jute, hemp, flax, kenaf, milkweed, grass, and banana trees.
- the fibers provide rigidity, strength, stiffness, and swelling properties to the composition.
- the material should be in the particulate, flake, or shaving form.
- the cellulosic fiber may comprise from about 10% to about 80% of the total lost circulation material by mass.
- the lost circulation material may also comprise oyster shell, other forms of calcium carbonate, mica, talc, ceramics, other minerals, and mixtures of one or more of the above with each other or with other components.
- These additives can provide additional strength and stiffness to the composition, or impart other useful properties.
- One such useful property is to increase the density of the material so that the composition will settle more easily in water.
- Calcium carbonate is a preferred additive for these purposes. Calcium carbonate is available from many sources. An economical source of calcium carbonate is precipitated calcium carbonate (PCC) from sugar mills or sugar refineries.
- the PCCs of sugar origin are inorganic precipitates resulting from the purification of beet or cane juices by liming and subsequent carbonatation.
- the PCCs of sugar origin typically have a powdery appearance with grayish hues. They readily agglomerate into lumps. PCCs are generated in enormous quantities as a byproduct of the sugar industry; currently PCC is used as a filling material for gravel mines, waste heaps, and the like; and in some cases it has been used for the correction of soils with excessively clay-like textures or to raise the soil pH.
- the PCC particle size typically varies from 10-3000 microns, although the size is not critical.
- the calcium carbonate or other mineral additive(s) may comprise from about 0% to about 30% of the total lost circulation material by mass.
- An optional component of the lost circulation material is a substance such as clay or starch with a high water absorbance and swelling capacity.
- An example is a granular absorbent such as Fullers Earth or Montmorillonite clay, with mean diameter of 33 microns and mean pore diameter of 30-70 nanometers, sold by Oil-Dri Corporation of America. This optional component may comprise from about 0% to about 10% of the total lost circulation material by mass.
- Another optional component is an oil to enhance lubricity, such as used cooking oil, used or residual motor oil, or other used or residual automobile fluids.
- a preferred source of oil is the residual oil in used motor oil containers - especially where those same containers are used as the source of the thermoplastic polymer.
- the optional oil component may comprise from about 0% to about 12% of the total lost circulation material by mass.
- a further optional component is an additive selected from the group consisting of stearic acid, organo-titanates (e.g., Ken-React LICA 09), maleated ethylenes, maleic anhydride, styrene/ethylene-butylenes/styrene triblock copolymer (SEBS), ethylene/propylene/diene terpolymer (EPDM), ethylene/octene copolymer (EOR), ethylene/methyl acrylate copolymer (EMA), ethylene/butyl acrylate/glycidyl methacrylate copolymer (EBA-GMA), Surlyn ionomers, Maleated ethylene/propylene elastomers (EPR-g- MAs), talc, resilient graphitic carbon, heat stabilizers, and other additives.
- This optional additive may comprise from about 0% to about 12% of the total lost circulation material by mass.
- the novel lost circulation materials are not merely mixtures of the several components. Rather, they are composites of the components. (Simple mixtures may also be present, in addition to the composites, although it is preferred to use composites alone.)
- the composites may be prepared through techniques otherwise known in the art for making composite materials. One such method is melt compounding, for example using intermesh, counter/co-rotating twin-screw extruders. The materials in the formulation are metered and fed to the extruder at an appropriate temperature. The extrudates are preferably quenched in a cold water bath or in air; and then may be pelletized or ground into granules of suitable sizes.
- Another technique is to make a blend with a high-speed kinetic mixer (e.g., a mixer manufactured by LEX Technologies, Brampton, Ontario, Canada and supplied by EcoLEX, I ⁇ C of Burlington, Ontario), followed by grinding to produce desired particle sizes.
- a high-speed kinetic mixer e.g., a mixer manufactured by LEX Technologies, Brampton, Ontario, Canada and supplied by EcoLEX, I ⁇ C of Burlington, Ontario
- a blend combining both common and engineering polymers e.g.,
- HDPE/PET may be manufactured through a novel two-step compounding process.
- a first extrusion is conducted at a higher temperature (i.e., a temperature that will melt the engineering polymer) to create a matrix with combined common (e.g., HDPE) and engineering polymers (e.g., PET, nylon).
- a second extrusion will occur at a lower temperature (i.e., a temperature that melts the common polymer but not the engineering polymer), at which point the cellulosic fiber is also added to the blend, avoiding or minimizing thermal degradation to the fibers.
- a higher temperature i.e., a temperature that will melt the engineering polymer
- a second extrusion will occur at a lower temperature (i.e., a temperature that melts the common polymer but not the engineering polymer), at which point the cellulosic fiber is also added to the blend, avoiding or minimizing thermal degradation to the fibers.
- recycled HDPE recycled PET, and any additives are compounded through extru
- cellulosic fibers are added to the HDPE-PET-additive mixture at about 160-180 0 C in a second extrusion.
- the PET remains in the solid state during the second, cooler extrusion.
- the extrudates are quenched in a cold water bath, or they are air-cooled, and then they are pelletized into granules.
- the novel lost circulation material may be used together with other additives known in the art to form oil-based, water-based, or synthetic oil-based drilling fluids; or they may be used with other well fluids such as cements, spacer fluids, completion fluids, and workover fluids.
- other additives include, for example, viscosifying agents, filtrate reducing agents, weighting agents, and cements.
- the novel lost circulation materials are preferably used in the fluid at a concentration level between ⁇ 2 ppb (pound per barrel) and -50 ppb. (Note 2 pound per barrel ⁇ 5.7 g/L; 50 pound per barrel ⁇ 143 g/L.)
- the composites used as lost circulation materials in the present invention may be purpose-made. Alternatively, they may be formed by crushing or grinding composite materials that contain suitable components, and that may have originally been manufactured for a different purpose, e.g., building materials such as wood-polymer composites, particleboard, fiberboard, and other types of engineered wood. Wastes may be used for this purpose (e.g., sawdust or scraps), or older materials may be recycled for use in the invention, rather than being discarded.
- a lost circulation material in accordance with the present invention may be combined with other lost circulation materials known in the art, such as cellulosic fibers, calcium carbonate, crump rubber particles, graphite, thermosets, thermoplastics, or clay.
- the material may be used as a pretreatment to inhibit differential sticking, seepage, or both. It is preferred to add a concentration between about 2.0 ppb (pound per barrel) to about 6.0 ppb to the entire drilling fluid system. Sweeps at a concentration of about 5.0 ppb to about 15.0 ppb may be pumped to inhibit seepage while drilling through specific geological zones. The concentrations and volume of sweeps may be adjusted as needed. Hourly additions may be made or adjusted if seepage occurs. If lost circulation occurs, then the material may be added at a higher rate until losses stop, e.g., 20-35 ppb.
- Aqueous fluid for water-based drilling fluids may, for example, be selected from fresh water, sea water, brine, water-soluble organic compounds, and mixtures of the above.
- Natural or synthetic oil to form an oil or synthetic-based fluid may, for example, be selected from diesel oil, mineral oil, polyolefm, polydiorganosiloxanes, ester- based oils, and mixture of the above.

- PET recycled HDPE, wood fiber, and other additives in a two-step extrusion process.
- the first extrusion was conducted at high temperature to create an HDPE/PET matrix, and the second extrusion added wood fiber to the blend, while avoiding thermal degradation to the fibers.
- HDPE, PET, and E-GMA bonding agent
- E-GMA bonding agent
- the extrusion temperature profile along the length of the extruder barrels was 130, 160, 190, 250, 270, 270, 270, 260, 260, and 25O 0 C, high enough to melt the PET.
- the screw's rotational speed was fixed at 150 rpm.
- the extruded strands were drawn by a pelletizer, and cooled in a cold water bath before being pelletized.
- the HDPE/PET ratio was fixed at 75/25 (w/w). Based on the total weight of HDPE and PET, the loading level of the E-GMA bonding agent was 1.0% by mass.
- pellets produced by the first extrusion were melt- blended with dried wood flour, and then extruded with the same Micro 27 extruder using a temperature profile of 130, 150, 160, 170, 180, 180, 170, 170, 160, and 16O 0 C (i.e., a typical temperature profile for HDPE/wood composites).
- Wood flour was fed downstream by a side feeder operated at 100 rpm.
- the extruder screw itself was set at a speed of 150 rpm.
- the wood flour-to-polymer matrix ratio was 40/60 (w/w).
- Maleated polyethylene (PE-g-MA, G- 2608, 1% total weight of fiber and polymer) was added during the second extrusion to help bond wood fibers to the polymer matrix.
- the extruded material was cooled in a water bath, and was then cut into pellets.
- Extruded TCB3 and TCB4 materials were granulated with an industrial granulator using a USA standard 8-mesh screen. The material was then screened using USA standard testing sieves and a Ro-Tap shaker. The sieves were assembled with smaller mesh number screens on top. A sample of 200 g was screened each time. After screening, material retained on each screen was collected and weighed to the nearest 0.01 gram using an analytical balance. The particle size distribution (PSD) was determined from measured weight data. The PSDs for TCB3 and TCB4 listed in Table 2. TABLE 2.
- PSD-TCB3 PSD-TCB4
- PSD-Sl PSD-S2
- PSD the PSD range for compatibility with the natural heterogeneity encountered in a particular formation.
- “Abram's rule” states that the median particle size of the bridging material should be equal to or slightly greater than one third of the median pore size of the formation.
- “Hand's rule” states that the D90 (the size x for which 90% of the particles by weight are smaller than size x) of the PSD should be equal to the pore size of the formation.
- Different PSDs for the composites of this invention can be selected by appropriate choice of grinding parameters, and of the mesh sizes used for screening the TCB particles.
- PSD-S2 and PSD-S3 were shifted to larger particle sizes as compared with PSD-Sl.
- Additional PSDs can be formed by appropriate combinations of different TCB compositions or particles.

- a typical formulation comprised 2 gallons of water, 5.44 grams of caustic soda, 432.00 grams of GEL, 21.56 grams of lignite, 10.76 grams of PC, and 108.00 grams of Rev dust, yielding a mud cup viscosity of 38 seconds. Mud viscosity was adjusted using additional gels.
- This formulated mud was used to test the performance of the TCB lost circulation materials using a permeability plugging apparatus (PPA).
- PPA permeability plugging apparatus
- a 350 ml sample of mud with a particular mud cup viscosity level (e.g., 52 seconds) was taken from a large, well-mixed mud bucket.
- a portion of LCM (either 20, 15, 10, or 5 gram) was combined with the 350 ml sample of mud.
- the prepared LCM was blended for five minutes with the 350 ml mud sample with a variable speed mixer.
- the mud with LCM was then poured into the PPA cylinder, and an aluminum disc with a 0.04 inch by 2.0 inch slot was inserted.
- WB Wood bullets from Prolog Inc. (New Iberia, LA) were also tested at the same four loading levels (20, 15, 10, and 5 grams material/350 ml mud), using otherwise identical procedures.
- Tables 3 and 4 list the PPA test data for both the TCBs and the wood bullets.
- the TCB material showed much higher sealing ability with water-based muds. At low loading levels, the pure wood material either failed or had large filtration losses, especially at low mud viscosity levels.
- the novel TCB material by contrast, could be used successfully at reduced loading levels (as low as 5 grams per 350 ml mud ⁇ 5 ppb). The use of lower loading levels allows better performance with reduced material, transportation, and handling costs.
- the novel LCM was tested in a commercially-available, synthetic mud containing calcium chloride, alkenes, barium sulfate, crystalline silica, cristobalite, crystalline silica, tridymite, and quartz.
- the synthetic mud was used to test the performance of the TCB lost circulation material using the permeability plugging apparatus (PPA) and an aluminum disc with a single 0.04 inch by 2.0 inch slot following the procedures otherwise described above for the water-based mud.
- PPA permeability plugging apparatus
- an aluminum disc with a single 0.04 inch by 2.0 inch slot following the procedures otherwise described above for the water-based mud.
- Pure TCB3 material at 15, 10, and 5.0-gram loading levels, or a combination of TCB3 (5 grams) and wood bullets (5 grams) were tested in 350 ml mud.
- PSD-Sl (as shown in Table 2) was used for the TCB3 material at each loading level.
- Tests were also made at two temperature levels (12O 0 F and 25O 0 F). Combined samples of TCB4 and wood bullets at various loading levels were blended with 350 ml mud, as otherwise described above. The PPA cylinder was heated to the target temperature (12O 0 F or 25O 0 F) prior to testing. The combined sample of TCB4 (5 grams) and wood bullets (WB-5 grams) led to almost a complete seal of the slot at 12O 0 F. Increasing the temperature to 25O 0 F led to some increased filtration loss. Increasing the TCB4 loading from 5 to 10 grams significantly reduced the filtration loss at 25O 0 F. The TCB performed well at elevated temperature levels. (Note: 25O 0 F ⁇ 121 0 C.) Table 7
- Examples 35 - 40 Use in diesel muds.
- novel LCMs were also tested with commercially-purchased diesel mud.
- This mud contained diesel oil, water, weight material, calcium chloride, emulsif ⁇ er, lime, filtration control agent, and gellant.
- Table 8 shows the electrical stability data (mean value of 10 data points with standard deviations shown in the parentheses). The data suggest that the TCB materials had no adverse effect on the electrical stability of diesel mud.
- Results are shown in Table 9.
- TCB3 alone or in combination with wood bullets, worked well in controlling filtration loss in diesel mud.
- the commercial graphite LCM had smaller particle sizes, allowing large filtration loss.
- Example 41 Using a commercial wood-plastic composite as a raw material.
- An alternative embodiment of the invention used as a raw material a commercial wood-plastic composite (viz., a composite sold for use as a building material).
- the material was re -melted and compounded with 20% precipitated calcium carbonate (based on total WPC blend weight) using a counter-rotating twin screw extruder (CTSE- V/MARKII from CW. Brabender Instruments Inc., South Gackensack, NJ, USA) at 17O 0 C.
- CTSE- V/MARKII counter-rotating twin screw extruder
- the extruded material was water-cooled, granulated, and screened into size categories of 8, 12, 16, 20, 40, 60, 100, and 200 mesh.
- Cements are commonly used in subterranean well drilling, completion, and remediation.
- a casing string is cemented in a well bore.
- a hydraulic cement is pumped into the space between the walls of the well bore and the outside of the casing string.
- the cement sets in the annular space and forms a sheath of hardened, impermeable cement.
- the hardened cement physically supports and positions the casing string in the well bore and bonds it to the walls of the well bore.
- a 46,000 Ib load of TCB having essentially the same formulation as TCB4 was prepared using an industrial-scale extrusion machine.
- the extruded material was granulated and sorted with an 8-mesh screen to produce a material that was similar to PSD- S2 (described in greater detail above).
- a water-based drilling fluid was pre-treated with a forty-pound sack of the PSD-S2- type material every hour while drilling through the Fruitland coal section and the Picture Cliffs formation.
- the well was drilled to a total depth of 3,317 feet or 1,011 meters. There was no substantial seepage or mud loss observed.
- Previous wells at the same general location over many years had been drilled with no treatment, or had been pre-treated with other lost circulation materials. The operators reported that these prior wells had suffered from losses or seepage, not seen with the new material.
