摘要： An improved formation testing method for measuring initial sandface pressure and formation permeability in tight zone formations exhibiting formation permeabilities on the order of 1.0-0.001 millidarcies is based on pressure transients which occur shortly after a tester enters its pressure build-up cycle and substantially before reaching final build-up pressure. The method makes an estimate of formation permeability based on fluid decompression transients which occur in the formation tester flowlines, shortly after the tester begins its build-up cycle. The method further estimates initial sandface pressure based on the change in pressure over time shortly after beginning the build-up phase. Accurate estimates of formation permeability and initial sandface pressure are thus made relatively early in the build-up cycle, thus substantially reducing the time required to make the pressure and permeability measurements.

摘要： A well in a poorly consolidated subterranean formation (10) bounded by one or more consolidated formations (12) is completed to prevent sand production from the poorly consolidated formation by drilling the well bore (14) into the consolidated boundary formation (12) adjacent to the poorly consolidated formation (10), creating a propped fracture (22) communicating with the well bore (14) in the consolidated boundary formation (12) which extends into the poorly consolidated formation (10), and producing fluids from the poorly consolidated formation (10) into the well bore (14) by way of the propped fracture (22).

摘要： An apparatus for injecting fluid into a wellbore. The apparatus comprises a housing (12) and a valve sleeve (50). The housing (12) has a chamber (36) and a port (30) in communication with the chamber (36). The chamber (36) is adapted to hold a first fluid, such as a cement accelerant, therein. The valve sleeve (50) serves to open the port (30) so that the fluid first fluid is free to flow out of the chamber (36) through the port (30) in response to the flow of a second fluid, such as cement. A portion of the valve sleeve (50) extends below the housing (12) so that when the valve sleeve (50) engages a surface therebelow, the valve sleeve (50) is forced upwardly to open the port (30). The housing (12) and/or the valve sleeve (50) may be made of a on-metallic material in order to facilitate drilling of the apparatus.

摘要： A logging-while-drilling tool for use in a wellbore (8) in which a well fluid is circulated in the wellbore (8) through a hollow drill string. The tool (100) is positioned in the hollow drill string (2) and sized to form an annular passage (55) between the drill string and the tool body (37), through which passage (55) drilling fluid is circulated. In addition to measurement electronics (14), the tool includes an alternator (38) for providing power to the electronics (14), and a turbine (39) for driving the alternator (38). The turbine blades (53) are driven by the flow (M) of well fluid introduced into the hollow drill string. The tool can also include a deflector (30) to deflect a portion of the well fluid away from the turbine blades (53).

摘要： A remotely-adjustable valve (24) employable in an enhanced-lift recovery system and a method of adjusting the same. The valve includes an elongated valve body (34) having a process fluid inlet and a process fluid outlet. An elongated valve stem (68) is disposed within the valve body (34) for axial displacement relative thereto to adjust a rate of process fluid flow between the fluid inlet and the fluid outlet as a function of a relative axial position of the valve stem with respect to the valve body (34). A cam (104) is disposed within the valve body (34) and couples the valve body (34) and the valve stem (68); the cam (104) provides a plurality of axial displacement positions thereon to place the valve stem (68) at a selected one of a plurality of relative axial positions with respect to the valve body (34). The valve body has a control fluid pressure port (42) for allowing a control fluid pressure to be introduced into and released from the valve (24) to reciprocate the valve stem (68) axially with respect to the valve body (34) between cocked and set positions. The cam (104) is movable from a first axial displacement position to a second axial displacement position as the valve stem (68) is reciprocated. A difference between the first and second axial displacement positions causes an adjustment of the rate of process fluid flow between the fluid inlet and the fluid outlet.

摘要： A locator and setting tool assembly (70), which is capable of locating and then setting a barrier member (200) within a cased wellbore or other string of tubular members in a manner such that the barrier member will not be set at a casing joint, includes a joint locator (72) and a setting assembly (74). The setting assembly (74) is connectable to the barrier member (200), eg a packer. In use, a planned barrier setting point within a cased wellbore is established based upon recorded well logs and customer requirements, and then an actual joint location is established and the barrier then set nearby.

摘要： A tubing-manipulated valve assembly (200) for control of fluid flow in a flowbore. The valve assembly (200) comprises a pivotable flapper plate (202) that is specially-shaped to include a semicylindrical channel which substantially aligns with a flowbore when the plate (202) is in an open position to cause the plate to conform closely to the interior profile of a wellbore. The plate (202) is operable between an open position in which the plate (202) is generally aligned with the flowbore and a closed position in which the plate (202) substantially seals the flowbore.
