Abstract: A multi-zone single trip open hole completion system includes an outer tubular assembly including an uphole end, a downhole end, an inner tubular assembly, an anchor arranged on the outer tubular assembly, and an anchor setting assembly provided on one of the outer tubular assembly and the inner tubular assembly. The anchor setting assembly is operable to selectively set the anchor. An isolation flow path is in the outer tubular. A flow control system is arranged on the inner tubular assembly. The flow control system selectively blocks flow through the inner tubular assembly. A remotely operated valve is arranged in one of the inner tubular assembly and the outer tubular assembly. The remotely operated valve is operable to close fluid flow through the tubular. An isolation packer is arranged along the outer tubular assembly. Closing the remotely operated valve enables the anchor, and the isolation packer to be set.

Abstract: A method of monitoring a reservoir comprising setting at least one barrier in a well separating it into upper and lower isolated sections. A perforating gun or other perforating device is provided in the lower isolated section, along with a control mechanism, wireless communication device and a pressure sensor. After the barrier is set, the perforating gun is activated in order to create at least one perforation between the well and a surrounding reservoir. The well, or part of it, is suspended or abandoned but the pressure is still monitored and a wireless, preferably acoustic or electromagnetic, data signal is transmitted from the lower isolated section to above the barrier. Data from the suspended/abandoned part of the well may be used to infer characteristics of the reservoir so that it may be exploited more appropriately especially through another well.

Abstract: A method of perforating a wellbore is provided. The method includes generating a shockwave that propagates throughout said wellbore by firing a perforation device at a perforating direction, and measuring the shockwave at a fiber optic cable in the wellbore using the fiber optic cable. The method further includes determining an orientation of the fiber optic cable relative to the perforating direction based on the shockwave and the perforating direction, and changing the perforating direction based on the orientation of said the optic cable for a subsequent perforation of the wellbore to minimize damage to the fiber optic cable during the subsequent perforation. The fiber optic cable is an existing cable that has been deployed before the method starts.

Abstract: A rotary steering tool includes a steering member configured to move between a retracted configuration and an extended configuration. The rotary steering tool also includes a pump configured to pump a fluid, a power source independent of the downhole motor, the power source configured to power the pump, and a piston in fluid communication with the pump.

The rotary steering tool includes a controller to operate the pump at a range of operating system pressures, and a variable pressure control valve. The variable pressure control valve adjusts the operating system pressure between the range of operating system pressures to adjust the force applied to the steering member.

Abstract: An apparatus, a system and a process may be used for regulating a wellhead control mechanism. The apparatus may control actuation of the wellhead control mechanism by moving a moveable body of the apparatus between a first position and a second position. When the apparatus is in the first position, a valve actuator is actuatable. When the apparatus is in the second position the valve actuator is physically interfered from actuating. Additionally, when the apparatus is in the second position, the wellhead control mechanism cannot be actuated and is held in either an open, a partially open or a closed position. Further, a system may directly control an actuation of a wellhead actuation mechanism.

Abstract: An estimation system includes an acquirer, an inferrer, a corrector, and an estimator. The acquirer acquires a measured value of an outer surface temperature of a pipe through which fluid flows. The inferrer infers an execution time for a removal process for deposits on an inner surface of the pipe. The corrector corrects an estimated value used for estimating a thickness of the deposits, by using the measured value of the outer surface temperature of the pipe, which is acquired within a predetermined time from an inference result of the execution time for the removal process for the deposits. The estimator estimates the thickness of the deposits based on the corrected estimated value and the measured value of the outer surface temperature of the pipe.

The smart push force application tool is at an end away from the drill bit and includes a push force application wing rib having a telescoping function. The smart push force application tool is capable of automatically measuring an inclination angle and an azimuth angle and comparing the inclination angle and the azimuth angle with design values so as to control the push force application wing rib to output a push force in a telescopic manner based on a difference between the measured values and the design values and applying a push force to the drill bit. The drilling system achieves combined deflection under double action of drill bit push and pointing, greatly improving the deflection capability.
