Definitions

  • WFTs generally employ the same testing techniques but use a wireline to lower the test tool into the well bore after the drill string has been retrieved from the well bore, although WFT technology is sometimes deployed on a pipe string.
  • the wireline tool typically uses packers also, although the packers are placed closer together, compared to drill pipe conveyed testers, for more efficient formation testing. In some cases, packers are not used. In those instances, the testing tool is brought into contact with the intersected formation and testing is done without zonal isolation across the axial span of the circumference of the borehole wall.
  • WFTs may also include a probe assembly for engaging the borehole wall and acquiring formation fluid samples.
  • the probe assembly may include an isolation pad to engage the borehole wall. The isolation pad seals against the formation and around a hollow probe, which places an internal cavity in fluid communication with the formation. This creates a fluid pathway that allows formation fluid to flow between the formation and the formation tester while isolated from the borehole fluid.
  • the probe In order to acquire a useful sample, the probe must stay isolated from the relative high pressure of the borehole fluid. Therefore, the integrity of the seal that is formed by the isolation pad is critical to the performance of the tool. If the borehole fluid is allowed to leak into the collected formation fluids, a non-representative sample will be obtained and the test will have to be repeated.
  • the formation pressure measurement accuracy of drill stem tests and, especially, of wireline formation tests may be affected by filtrate invasion and mudcake buildup because significant amounts of time may have passed before a DST or WFT engages the formation.
  • Mud filtrate invasion occurs when the drilling mud fluids displace formation fluids. Because the mud filtrate ingress into the formation begins at the borehole surface, it is most prevalent there and generally decreases further into the formation. When filtrate invasion occurs, it may become impossible to obtain a representative sample of formation fluids or, at a minimum, the duration of the sampling period must be increased to first remove the drilling fluid and then obtain a representative sample of formation fluids.
  • hydrocarbons are stored in subterranean formations. Hydrocarbons are not typically located in large underground pools, but are instead found within very small holes, or pore spaces, within certain types of rock. Therefore, it is critical to know certain properties of both the formation and the fluid contained therein.
  • certain formation and formation fluid properties will be referred to in a general sense. Such formation properties include, but are not limited to: pressure, permeability, viscosity, mobility, spherical mobility, porosity, saturation, coupled compressibility porosity, skin damage, and anisotropy.
  • formation fluid properties include, but are not limited to: viscosity, compressibility, flowline fluid compressibility, density, resistivity, composition and bubble point.
  • Figure 2A illustrates the electronics module 20, which may include battery packs, various circuit boards, capacitors banks and other electrical components.
  • Figure 2B shows fillport assembly 22 having fillports 24, 26 for adding or removing hydraulic or other fluids to the tool 10.
  • Below fillport assembly 22 is hydraulic insert assembly 30.
  • Below assembly 30 is the hydraulic connectors ring assembly 32, which acts as a hydraulic line manifold.
  • Figure 2C illustrates the portion of tool 10 including equalizer valve 60, formation probe assembly 50 (or probe assembly 200), draw down shutoff valve assembly 74, draw down piston assemblies 70, 72 and stabilizer 36.
  • pressure instrument assembly 38 including the pressure transducers used by formation probe assemblies 50, 200.
  • formation probe assembly 50 is disposed within probe drill collar 12, and covered by probe cover plate 51. Also disposed within probe collar 12 is an equalizer valve 60 having a valve cover plate 61. Adjacent formation probe assembly 50 and equalizer valve 60 is a flat 136 in the surface 17 of probe collar 12. Probe drill collar 12 includes a draw down cover 76 for protecting other devices associated with the formation probe assembly 50 mounted in the collar 12, such as draw down pistons (not shown).
  • Formation probe assembly 50 and equalizer valve 60 are positioned in probe collar 12. Formation probe assembly 50 and equalizer valve 60 are mounted in probe collar 12 just above the flowbore 14. Flowbore 14 may be deviated from the center longitudinal axis 12a of probe collar 12, or from other portions 14b, 14c of flowbore 14, to accommodate at least formation probe assembly 50. For example, in Figure 5 , flowbore portion 14a is offset radially from the longitudinal axis 12a, and also from the flowbore portion 14b via transition flowbore portion 14c. Also shown are draw down piston assemblies 70, 72 and draw down shutoff valve 74.
  • Skirt 182 is detachably coupled to extending portion 119 by way of threaded engagement with surface 120 of central bore 121 (see Figure 6A ), or other means of engagement, such as a pressure fit with central bore surface 120. Because the seal pad/skirt combination may be detachable from extending portion 119, it is easily replaced in the field. Alternatively, seal pad 180 may be coupled directly to extending portion 119 without using a skirt.
  • formation probe assembly 50 will continue to pressurize reservoir 54 until reservoir 54 reaches a certain pressure P 1 .
  • formation probe assembly 50 will continue to apply pressure to seal pad 180 by pressurizing reservoir 54 up to the pressure P 1 .
  • the pressure P 1 applied to formation probe assembly 50 may be 1,200 p.s.i.
  • snorkel assembly 98 The continued force from the hydraulic fluid in reservoir 54 causes snorkel assembly 98 to extend such that the outer end of snorkel extension 126, inlet end 131 of screen 100 and the top of scraper 160 extend beyond seal pad surface 183 through seal pad aperture 186.
  • This snorkel extending force must overcome the retract force being applied on the retract side of snorkel base portion 125 facing piston shoulder 172.
  • the retract force provided by retract accumulator 424 and the retract valves, was greater than the extend force, thereby maintaining snorkel 98 in the retract position.
  • the extend force continues to increase until it overcomes the retract force at, for example, 900 p.s.i.
  • Snorkel assembly 98 stops extending outward when snorkel base portion 125 comes into contact with shoulder 172 of piston 96.
  • Scraper tube 150 and scraper 160 are still in the extended position, as is best shown with the snorkel assembly and piston configuration of Figure 7E .
  • scraper tube 278 When scraper tube 278 is fully retracted, fluid may be communicated between central passageway 203 of stem 212, passageway 243 of outer stem 219, passageway 275 of scraper tube keeper 270, passageway 279 of scraper tube 278, bore 287 of scraper 288, scraper apertures 289, screen 290, and the surrounding environment 15.
