摘要： A test packer is lowered to a set liner hanger in a locked position that prevents the seal and slips from setting during running in. A first ball is dropped to shift a sleeve to release the grip of dogs to a groove on an outer housing. Setting down weight sets the test packer seal and sets the slips. After the casing integrity pressure test is done the test packer is lifted to again position the groove in the outer housing by the dogs. A second ball lands on the same seat now enlarged due to earlier movement and breaks a retainer on a locking sleeve. A spring return or continued downhole motion of the locking sleeve locks the packer in the run in position. Subsequent rotation and circulation can take place as completion fluid is circulated in. A circulation port above the packer can be opened optionally for circulation or reversing above the test packer.

摘要： A technique facilitates a drilling operation by providing a drill bit having limited magnetic influence. The drill bit comprises a bit head formed with a non-magnetic bit head material. Cutting elements may be attached to the bit head to facilitate cutting of rock and other formation material during drilling of a borehole. The drill bit also comprises a bit body formed with a non-magnetic body material. The bit head and the bit body are joined to construct a non-magnetic drill bit which has no or limited magnetic influences on, for example, sensors located proximate the drill bit.

摘要： An earth-boring drilling tool comprises a cutting element. The cutting element comprises a substrate, a diamond table, and at least one sensing element formed from a doped diamond material disposed at least partially within the diamond table. A method for determining an at-bit measurement for an earth-boring drill bit comprises receiving an electrical signal generated within a doped diamond material disposed within a diamond table of a cutting element of the earth-boring drill bit, and correlating the electrical signal with at least one parameter during a drilling operation.

摘要： A down hole tool including a compression surface, a compression surface axis, and at least one support member configured to attach the compression surface to a well drilling tool assembly, wherein the extendable support member is extendable by an extension force provided to the support member. The down hole tool is rotable relative to an axis of the well drilling tool assembly, and as the well drilling tool assembly rotates, the at least one compression device exerts a lateral force along a sidewall of a wellbore. Also, a method of forming filter cake comprising releasing a drilling fluid and contacting the drilling fluid with a mechanical pressure on the sidewall of the wellbore and the drilling fluid.

摘要： A sealing system can include an annular seal comprising a resilient material, and a spring which applies a compressive force to the seal as a resilience of the material diminishes, the spring being external to the seal. A sealing method can include installing a seal in a well tool, the seal being compressed radially as a result of the installing, and a spring external to the seal exerting a compressive force on the seal. A well tool can include a seal radially compressed between seal surfaces of the well tool, due to the seal having a greater radial dimension as compared to a radial distance between the seal surfaces, and a spring which exerts a compressive force on the seal, the spring being external to the seal.

摘要： A logging tool electronics system is disclosed (FIG. 1) with noise minimization features and pulse compression signal processing techniques to improve the signal-to-noise ratio of array induction logging tools. The borehole is radiated with a magnetic field produced by a configurable multi-frequency sine wave signal stimulus section driving a fully differential single transmitter coil. Received signals from multiple mutually balanced fully differential receiver arrays are processed by receiver signal chains using adaptive algorithms under firmware control. The received signals are used to determine the conductivity and resistivity of the formation surrounding the borehole.
