The BHA includes a measuring-while-drilling (MWD) module, a wireless power and data connection, and a rotary steerable system (RSS). The MWD module is configured for coupling to a drill string, and includes a power generation component and a direction and inclination (D&I) survey package. The wireless power and data connection is disposed above a drilling motor in the drill string and for providing power and data connectivity between the MWD module and the drilling motor. The RSS is coupled to the drilling motor for receiving power from and communicating with the MWD module via the wireless power and data connection and the drilling motor.

Abstract: Compositions comprise polyacrylamide, a non-metallic crosslinker and a pH- adjustment material. Such compositions have utility in the context of remedial cementing, plug cementing in particular. The compositions may be pumped into a subterranean well, where they polymerize and form a support on which a cement plug may sit. The support may maintain the position of the cement plug in the wellbore and minimize cement-plug contamination.

Abstract: A method of treating a wellbore penetrating subterranean formations including injecting into the wellbore a treatment fluid including a drilling fluid and a mixture of elongated shapeable particles, and allowing the elongated shapeable particles to undergo a change in shape. The elongated shapeable particles are selected from fibers, ribbons, flakes, films, sheets, platelets, and flakes, and have aspect ratios greater than or equal to 20. The change in shape is most commonly due to an increase in temperature of the elongated shapeable particles. The elongated shapeable particles may be made of multiple polymer components. Preferred elongated shapeable particles are shrinkable fibers. The change of shape of the elongated shapeable particles distributed in the drilling fluid causes the reorganization and agglomeration of the solid particles. The treatment may be mitigation of fluid loss or hydraulic fracturing

Abstract: A method for determining a formation thermal neutron decay rate from measurements of radiation resulting from at least one burst of high energy neutrons into formations surrounding a wellbore includes determining a first apparent neutron decay rate in a time window beginning at a first selected time after an end of the at least one burst, a second apparent decay rate from a time window beginning at a second selected time after the burst and a third apparent decay rate from a third selected time after the burst. The second time is later than the first time. A thermal neutron capture cross section of fluid in the wellbore is determined. A decay rate correction factor is determined based on the first and second apparent decay rates and a parameter indicative of the wellbore capture cross-section. The correction factor is applied to the third apparent decay rate to determine the formation thermal neutron decay rate.

Abstract: Methods for cementing a subterranean well comprise installing a casing string into a borehole, wherein the casing string comprises a metal having a coefficient of thermal expansion (CTE) lower than about 6 x 10-6?/C. A cement sheath is then placed between the exterior surface of the casing string and the formation wall. The low-CTE metal may reduce casing shrinkage when the well temperature falls during stimulation treatments, cyclic steam injection or when the well temperature reaches equilibrium at the top of a long casing string.

Abstract: A technique facilitates cutting of a conveyance or other member passing through a tubular system, such as a landing string and/or a subsea test tree. The technique utilizes a pair of cutter blades pivotably coupled together at a pivot which may be located adjacent a pair of cutting edges. The pair of cutter blades is located in a body which has a passage sized to enable movement of certain tools and conveyances therethrough. The pair of cutter blades is connected to a piston actuated mechanism which may be selectively actuated to move the cutting edges toward each other and across the passage extending through the body. When the cutter blades are in an open position, the tools and/or conveyance may be moved through the cutter body along the passage.

Abstract: Systems and methods are described for monitoring displacement on structural elements of subsea systems such as on components of a subsea pipeline network used to transport production fluid from a subsurface wellhead to surface facilities. The described techniques sense changes in displacement using a sensing blade, for example made of crystalline material such as sapphire, that is anchored to the structural element such that it is approximately perpendicular to the direction of sensed displacement. Displacement is sensed as bending of the sensing blade using one or more instruments fabricated on the blade. Robustness of design is in part provided by additional flexible non-sensing blades mounted in parallel to the sensing blade.

Abstract: Fracture monitoring and characterisation of a subterranean fracturing process is described. Hydraulic fracturing conditions intended to induce tensile crack opening or compressional crack closure of a fracture responsible for a microseismic event in the Earth formation are selected and a hydraulic fracturing operation is performed using the selected conditions to cause tensile crack opening or compressional crack closure of the fracture responsible for a microseismic event in the Earth formation. Induced motion data from the microseismic event is received using a plurality of receivers, and the received data is analysed to track the development of the fracture responsible for the microseismic event and/or to track a proppant distribution within the fracture.
