In a more specific modality, oil-based drilling muds are used in the sinking of boreholes, especially deep level boreholes sunk in search of hydrocarbons (including gas), to maintain the pressure against the producing field to prevent blowouts, to lubricate the drill pipe, to cool the rock drill and act as a carrier for the cuttings of the excavated drilling. The fluid or drilling mud is pumped along the
drill pipe through nozzles in the auger at the bottom of the borehole and above the annular space between the drill pipe and the borehole wall. The perforated cuts, generated by the auger, are collected with the mud and transported to the surface of the borehole where they are separated from the drilling mud and discarded. The drilling mud is then cleaned and reused. The drill pipe is then able to operate freely inside the borehole. In another specific embodiment herein, oil-based drilling mud is generally used in the form of reverse emulsion sludge.

In another specific embodiment herein, it is well known that organic compounds containing a cation will react with clays having an anionic surface and interchangeable cations to form organarcillas. Depending on the structure and amount of the organic cation and the characteristics of the clay, the resulting organarcilla can be organophilic and thus have the property of dilation and dispersing or gelling in certain organic liquids depending on the
concentration of organarcilla, the degree of shear applied and the presence of a dispersant. See for example the following US Pat. Nos., All incorporated herein by reference in their totals for all purposes: 2,531,427 (Hauser); 2,966,506 (Jordan); 4,105,578 (Finlayson and Jordan); 4,208,218 (Finlayson); and the book "Clay Mineralogy", 2nd Edition, 1968 by Ralph E. Grim, McGraw-Hill Book Co. , Inc., particularly Chapter 10 - Clay Mineral-Organic Reactions, pp. 356-368 - Ionic Reactions, Smectite, and pp. 392-401 - Organophilic Clay-Mineral Complexes. In another specific embodiment herein, the organophilic clays with base in attapulgite and sepiolite generally allow the suspension of the solid filling phase without drastically increasing the viscosity of the oil-mud, while the organophilic clays with base in bentonite, hectorite and saponite they are gelling agents and appreciably increase the viscosity of the oil-based mud. In one embodiment, some clays (such as bentonite) can be used as builders or viscosity in drilling muds, and are modified to make them organophilic in such a way that the layers in the clay are separated from each other and adsorb the oil that exists . Still in another specific modality in the
present, the organophilic clays based on attapulgite or sepiolite can have a milliequivalent ratio (ME ratio) of about 30 to about 50. The ME ratio (milliequivalent ratio) is defined as the number of milliequivalents of the cationic compound in the organarcilla, per 100%. grams of clay, 100% active clay base. In one embodiment herein, organophilic clays based on bentonite, hectorite or saponite can have an ME ratio of about 75 to about 120. The optimum ME ratio will depend on the particular clay and the cationic compound used to prepare the organarcilla. In general, it has been found that the gelling efficiency of organophilic clays in non-polar oleaginous liquids increases as the ME ratio increases. In a specific embodiment, the more specific organophilic clays based on bentonite, hectorite or saponite can have an ME ratio in the range of 85 to about 110.

In another specific embodiment herein, the mixture (b) may comprise an oil phase. In another more specific embodiment, the oil phase can be any oil phase known or commercially and / or industrially used, which occurs naturally or is added in a conventional manner by known and / or conventional methods. In a specific embodiment herein, the oil phase may comprise a hydrocarbon. In another more specific embodiment, the oil phase may comprise a fraction of petroleum oil, natural or synthetic oil, tallow, fat, wax, silicone containing synthetic oil, silicone containing fat and combinations thereof.

In a specific embodiment herein, the oil phase may also comprise other dissolved or suspended constituents, including suspended solid constituents which remain part of the oil phase after the separation of another solid phase. In a specific embodiment, for example, oil-based drilling fluid typically comprises a base oil, additives such as surfactants and viscosity modifiers, and suspended clay particles, as described herein. In a specific embodiment, the clay imparts body to the fluid so that the circulating fluid can entrain the perforation cuts and haul them from the borehole. In another specific embodiment, the drilling fluids also frequently contain a finely divided densifying material such as barite, a dense mineral that increases the density of the fluid for use in deep wells. In another specific embodiment, both the clay and the densifying material are typically so finely divided that they can remain suspended in the base oil over a substantial amount of time. In yet another specific embodiment, in the separation of the drilling fluid from the perforation cuts according to this invention, the drilling fluid, including its suspended solid constituents, may constitute the "oil phase" and the
Piercing cuts can constitute the "solid filling phase." In yet another specific embodiment herein, if a given particulate solid filler can be separated from an oil phase as described herein, it is believed that it depends in part on the affinity of the oil phase for the solid filler (s), ie , of the tendency of the oily phase to wet the solid filler (s), and also in part of the particle sizes of the solid filler, the larger particles being easier to separate. In a specific embodiment, the base oil in the drilling fluid has a relatively strong affinity for the clay particle (s), while the shale oil has a lower affinity for the siliceous particle (s) found in the extractive mud. shale oil ashes. In another specific embodiment herein, the clay, for example, bentonite, the particle or particles in the drilling fluid are extremely fine, approximately 0.05 to 5 microns, averaging approximately 0.5 microns, while the ash particles in the extractor mud of ashes are in the order of 100 times larger, approximately 0.5 to 200 microns, averaging approximately 50 microns. In a more specific embodiment herein, the clay particles are charged electrically and therefore have a high affinity for
the oil phase, while the siliceous particles are electrically neutral and therefore have a lower affinity for the oil phase. Thus, in a specific embodiment of this invention, the clay particles in the drilling fluid remain with the base oil when the fluid is separated from the drilling cuts, while in another embodiment, the ash particles are separated from the drilling fluid. shale oil. Still in another specific embodiment herein, it is not possible to affirm in advance, for all possible combinations of oils and particulate solids, precisely which mixtures can be successfully separated according to the modalities described herein, but as a general rule, however , particles that vary in average size (the largest dimension in cross section) of about 50 microns and larger can be separated from hydrocarbonaceous oils, such as crude and refined petroleum oils and similar oils produced from bituminous shale, sands impregnated with petroleum pitch, coal and the like, without difficulty using the modalities of the composition described herein. In yet another specific embodiment herein, the oil phase comprises in particular from about 1 to about 90 weight percent,
more specifically from about 2 to about 70 weight percent, and very specifically from about 5 to about 50 weight percent of the mixture (b;, based on the total weight of the mixture (b) before the separation of the mixture (b) Still in another specific embodiment herein, the oil phase which is substantially insoluble in the aqueous phase comprises an oil phase which specifically is less than about 10 volume percent soluble in the aqueous phase, more specifically less than about 5 volume percent soluble in the aqueous phase and very specifically less than about 1 volume percent soluble in the aqueous phase, the percentages by volume based on the total volume of the oil phase. The following are given for the purpose of illustrating the invention of the present case, and are not intended for any purpose to set limitations to the embodiments described herein.

In another specific embodiment in this description it will be understood that one or more silicone surfactants (a) and mixtures of different silicone surfactants (a) can be used as described in this description.
It will be understood herein that the phrases "% by weight" and "percent by weight" are interchangeable as described herein. It will be understood that time, as expressed in the examples, is always total time from the start of the reaction mixture of polysiloxane hydride, allyl ether (or allyl alcohol), 2-propanol (solvent, if present), buffer and catalyst. It will be understood herein that the terms "catalyst", "platinum" and "platinum catalyst" are used interchangeably herein. In a specific embodiment herein, it will be understood that an initial catalyst charge is added at a time. If the reaction does not proceed to completion (ie, the consumption of all silicone hydrogen functionality), additional gradual charges of catalyst are made to direct the reaction to termination. In another specific embodiment herein, it will be understood that Examples A, B and C are organic demulsifiers which are benchmarks for comparing the benefits of the subject description, and the materials of Examples A, B and C by themselves are formulations whose compositions are closely guarded trade secrets. The sludge, which was studied in the examples in the following, (from a service company in oil and gas applications) in an oil-based mud used for marine drilling, removed from the well after use, mechanically separated from its cuts. It contains
organarcillas covered with polymers, barium sulfate, biocides, emulsifiers, corrosion inhibitors, mineral oil, traces of crude oil from the well, water, inorganic salts, remaining cuts. It will be understood herein, in this full description, that the use of the h and hours for the time must be estimated equivalent. The method of manufacturing the starting materials, such as the non-limiting group of the polysiloxane hydrides, is well known in the art, as described in U.S. Patent Nos. 5,542,960; 6,221,815; 6,093,222; and 5,613,988, the contents of all of them are incorporated herein by reference in their totals.
1. Phasing Separation Test A first qualitative selection test of organic versus silicone based demulsifiers, generally comprised of the composition described herein, was performed. For this, 50 grams (g) or (gms) of a used drilling mud (mud) was used in a glass flask, then the required amount of silicones (silicone surfactant) as described in the following ( which varies from 0.1 weight percent to 5 weight percent for the largest concentration range (or 0.05 g to 2.5 g silicone plus 50 g mud with the weight percent silicone based on the total weight of the
mud), was added to the mud). The glass flask was then vigorously stirred by hand for a period of 10 seconds measured with a stopwatch, and the sample was allowed to settle for a non-specific period of time, but for a minimum of one day before selection. Generally the qualitative observation of phase separation with time was made in the first 150 minutes where most of the phase separation occurred, this was an approximate test that was determined qualitatively. If a large phase separation of 40 to 50 volume percent of the aqueous phase occurred compared to the full volume of mud and silicone sample, it was denoted by the term "SI" in Table 1, if a small separation of phases of approximately 10 percent by volume, was denoted by "MODERATE" in Table 1, and when a phase separation did not occur it was denoted by "NO" in Table 1.

Transmission detector receives the light, which goes through the sample (0o from the incident beam) while the backscatter detector receives scattered light through the sample at 135 ° from the incident beam. (The 135 ° angle was chosen to be outside the coherent backscatter cone). The detection head scans the total length of the sample (approximately 45 mm), acquiring transmission and backscatter data every 40 μm (1625 transmission and backscatter acquisitions per scan). These measured flows are calibrated with a non-absorbent reflectance standard (calibrated polystyrene latex beads) and a transmittance standard (silicone oil). The signal is first treated by a Turbiscan Lab voltage-to-current converter. The integrated microprocessor software handles data acquisition, in analogy to digital conversion, data storage, motor control and computer dialogue.
Description of the Turbiscan graphs: The silicone surfactant (a) was added at the top of a drilling mud (weight% silicone surfactant (a) / mud weight, the weight of the mud being 50 g in a flask glass, which was vigorously shaken by hand for 10 seconds (measured using a wristwatch) and then poured into the glass
borosilicate used for the Turbiscan Lab instrument. Explorations were started as soon as possible after preparation to see sediment settlement. The scans were taken every minute for 10 minutes and then every 5 minutes for the next 50 minutes, and then every 30 minutes for the next 3 hours and 30 minutes and finally every 2 hours for the next 18 hours). Figure 1 shows a graph obtained by the Turbiscan Lab instrument from the beginning of the demulsification using the silicone surfactant (a) and for a period of 22 hours after the start of the demulsification. The vertical axis describes the diffuse reflectance or normalized backscattering with respect to a standard non-absorbing reflector and the horizontal axis represents the height of the sample in millimeters (mm) (0 mm corresponds to the bottom of the measurement cell). Due to the action of the silicone surfactant (a) on the mud, there is a sedimentation of the heavy solid particles (barite and clays) that appear quickly, shown in the backscatter plot by the change of sharp decrease on the right side of each curve to the left (corresponding to the decrease in the interface between the upper aqueous phase and the solid filling phase). It is interesting to note that the Turbiscan instrument
Lab allows the detection of the destabilization of drilling mud at an early stage even when the medium is not transmitting light. Figure 1: Transmission and backscattering data of the Turbiscan Lab instrument at 29 degrees Celsius (° C) for a drilling mud from the Service Company treated with 2% by weight of Example 10B (Y-17014) based on the weight of drilling mud sample (corresponding to 1 g of silicone with 50 g of mud). Analysis of the data: the position of the air / drilling mud interface at the beginning of the demulsification using the silicone surfactant (a) gives the total height of the drilling mud in the Turbiscan tube and is on the right side of the first transmission curve when the curve finds the transmission axis zero. The lower part (minimum height of the drilling mud in the tube) of the Turbiscan glass is given by the left side of the first curve when the curve leaves the transmission axis zero. The evolution of the demulsification of the drilling mud using the silicone surfactant (a) is indicated by the decrease in the position of the aqueous phase / solid filler interface over time. This position is given by the point of inflection of the sharpest decrease in the backscatter and the shift to the left (the height of the solid fill phase is then decreasing with time). The
Aqueous phase is then deduced from the complement to this position, compared to the whole sample. (See Tables 2a, 2b and 2c for different concentrations of demulsifiers ranging from 2 to 0.5% percent by weight of demulsifier based on the total weight of the sludge) The same experiments were performed for the different silicone surfactants (a) and then the results were compared with three other organic demulsifiers provided by a Service Company which is a customer. Example A belongs to the family of the ethoxylated alcohol and Example B belongs to the family of glycosides, Example C is a commercially secret compound that is unknown and was provided as a reference under a secret agreement, thus avoiding Applicants investigate or disclose their description. The results were compared in terms of percentages of the position of the solid phase / aqueous phase interface. In conclusion, from Tables 2a, 2b and 2c, the largest and fastest separation of aqueous phases was obtained for Example 41 (Y-17015) in the first 400 minutes (min). As described in the foregoing, Examples A, B and C are benchmarks for comparing the benefits of the subject description, and the materials of Examples A, B and C by themselves are formulations whose compositions are
closely guarded business secrets. 3. Water clarity - Haze 2100 ratio turbidity measurement The best estimate of the clarity of the aqueous phase after separation was using Hach 2100 NTU turbidimeter (NTU = turbidity nephelometric units) since the demulsification of the mud perforation by the silicone or organic surfactant leads to the adhesiveness of the drilling mud sediments in the wall of the glass flask. In this way, the aqueous phase had to be removed without contaminating it to measure its turbidity. 250 g of drilling mud were treated with demulsifier in the required amount. The mixture was vigorously shaken by hand for 10 seconds and allowed to settle for two specified times such as 6 hours and 12 hours. About 30 g of the upper aqueous layer were removed with a plastic pipette in the middle part of the aqueous phase (to avoid taking the surface of the water and the sediments in the lower part of the aqueous phase) at different times. The turbidity of the extracted water was measured (see Table 4). Turbidity measures the dispersion of light through water caused by the materials in suspension or solution. Suspended and dissolved material may include clay, silt, finely divided organic and inorganic matter, soluble organic compounds of color and plankton and other organisms
microscopic Other methods used for drilling mud analysis: (a) Measurement of the nonvolatile content of drilling mud or different phases after phase separation: The test was performed on samples of 2 grams (either drilling mud alone or the separated aqueous phase or the separated phase of solid filler) by using a thermogravimetric balance and heating the sample to approximately 160 ° C. The evolution of the disappearance of the volatile compounds was observed by measuring the weight loss from 100 weight percent to 0 weight percent based on the total weight of the volatile compound (s). The remaining non-volatile compound (s) corresponded to the remaining weight in the aluminum plate. The percentages obtained corresponded to the ratio of the remaining weight after heating to the initial mass of 2 grams. (See Table 3a for the results). (b) The analysis of the water content in the solid filling phase (sediments, barite), after the phase separation (and also for the drilling mud only) and after the aqueous phase was discarded, was carried out using the Karl Fischer method. For this test, each sample was homogenized by shaking. About lOg of sample were taken in 50 ml of Isopropyl Alcohol (IPA) in a polypropylene container. The sample solution in IPA is
It stirred well to extract water from the mud. (See Table 3b for the results.) The titration of Silicon content by aluminum molybdate was performed according to the method of ASTM D859-00 (Standard test method for silica in water) in the separated water phases after treat the mud with 2% w / w of demulsifiers (separated water taken after 6 or 12 hours). The silicon content in the aqueous phase had to be measured to see where the remaining silicon is; for environmental reasons, in case of discharging the separated water to the sea or on land, (see Table 3c). The presence of heavy metals was also measured in the separated aqueous phase (both after 6 hours and 12 hours (total time after agitation of the treated sludge with 2% w / w of demulsifier (or Ig plus 50 g of sludge ))) using an Inductively Coupled Plasma Atomic Emission Spectrometer (ICP). (description of the method: 5g of the water layer was weighed in a beaker, evaporated slowly to dryness at 50 deg C. The residue obtained was boiled with concentrated nitric acid to leach the possible heavy metals in the residue. it was compensated to 25 ml using Milli-Q water, and analyzed by ICP) (see Table 3d).

In a specific embodiment, the following definitions are defined for the following examples: M = Si (CH3) 3-01 / 2 MH = YES (CH3) 2-O? / 2 DH = YES (CH3) (O? / 2) 2 D = YES (CH3) 2 (O? / 2) 2 MM = hexamethyldisiloxane
MHMH = 1, 1,3,3-Tetramethyldisiloxane D4 = octamethylcyclotetrasiloxane L31 = MDH50M MDHXM or MHDXMH are also called SiH or polysiloxane hydride The catalyst is either a 3.3 percent by weight (% by weight) solution (based on the weight of ethanol) of chloroplatinic acid in ethanol or a Karstedt PTS type catalyst solution of ("Platinum chelated to tetravinylcyclotetrasiloxane") in toluene containing 1% by weight of platinum metal (based on the weight of toluene). The Karstedt PTS type catalyst is one commercially available in ABCR as a Platinum-cyclovinylmethylsiloxane complex in cyclic methyl vinyl with CAS number 68585-32-0. The allyl content (or vinyl content or unsaturation rate) of a molecule is the percentage ratio by weight between the molecular weight of the allyl (or vinyl) group and the molecular weight of the total molecule. It will be understood herein that the demulsifier and the silicone surfactant (a), as described herein, are interchangeable. A molar excess of 30% of the allyl ether corresponds to an excess of 30% of the allyl ether in moles, compared to the polysiloxane hydride as described in each example in the following.
MHMH is commercially available from Flu a (CAS No. = 3277-26-7) as 1, 1, 3, 3-Tetramethyldisiloxane. For paragraphs 136 to 158 it is noted, in various examples in the following, that the NMR spectra indicated that the reaction product can sometimes be bound either Si-C (between the polysiloxane hydride and the allyther). linked Si-OC. The type of reaction product was then indicated. Example 01 (MF V) is a material prepared in the laboratory, obtained from the hydrosilylation reaction between MHD8MH and a molar excess of 30% of monoallyl ether of trimethylolpropane, which has the formula CH2 = CH-CH2-0-CH-C (CH2OH) 2-CH5. A glass reactor covered with nitrogen at atmospheric pressure, which was equipped with a temperature probe, a stirrer, a condenser and a nitrogen inlet, was charged with 30 grams of polysiloxane hydride of the balanced formula MHD8MH containing 61.7 centimeters cubic per gram (cc / g) of active hydrogen (ccH2 / g), 18 grams of the allyl ether with an allyl content of 23.3 percent by weight and 48.9 grams of 2-propanol (solvent); then 114 microliters of dibutylethanolamine was added as a buffer. The (heterogeneous) reaction mixture was heated to 74 ° C and platinum catalyst was introduced as 98 microliters of a 3.3% solution of chloroplatinic acid in ethanol (based on the weight of ethanol), which corresponds to 10 parts per million (ppm) of platinum (platinum metal).
