摘要： A sensor module for a sensing apparatus configured for operation downhole, within a borehole. The sensor module comprises a sensor array having a plurality of sensors to sense selected formation parameters and a control system for selective and independent operation of each sensor of the sensor array. Each sensor of the sensor array is configured or designed as a discrete sensor unit for individual and independent communication and control. Each sensor of the sensor array may have an associated electronics module that provides standardized electronic connectivity with the control system.

摘要： A borehole seismic acquisition tool configured for release from a stuck position within a borehole having a tool body with at least one sensor package, an anchoring arm, and anchoring arm linkage adapted to connect the anchoring arm to the tool body. The anchoring arm linkage includes a weakpoint mechanism adapted to break in response to a minimum threshold amount of breaking force being applied upon the weakpoint mechanism. The anchoring arm includes a first end adapted for contacting a borehole wall surface and a second end pivotally attached to the anchoring arm linkage. The anchoring arm also includes a movable cam removably secured to the first end via a first connector pin. The cam being at least partially rotatable about the first connector pin and configured and arranged to rotate against the borehole wall by a pulling force at a top portion of the borehole seismic acquisition tool.

摘要： A system and method for obtaining a clean fluid sample for analysis in a downhole tool are provided. In one example, the method includes directing fluid from a main flowline of the downhole tool to a secondary flowline of the downhole tool. While the fluid is being directed into the secondary flowline, sensor responses corresponding to the fluid in the secondary flowline are monitored to determine when the sensor responses stabilize. The secondary flowline is isolated from the main flowline after the sensor responses have stabilized. A quality control procedure is performed on the fluid in the secondary flowline to determine whether the captured fluid is the same as the fluid in the main flowline. Additional fluid from the main flowline is allowed into the secondary flowline if the captured fluid is not the same.

摘要： A technique is described for releasing a borehole seismic acquisition tool from a stuck position within a borehole. The borehole seismic acquisition tool includes a tool body having at least one sensor package. The borehole seismic acquisition tool further includes an anchoring arm, and anchoring arm linkage adapted to connect the anchoring arm to the tool body. The anchoring arm linkage includes a weakpoint mechanism adapted to break in response to a minimum threshold amount of breaking force being applied upon the weakpoint mechanism. The anchoring arm includes a first end and a second end. The second end of the anchoring arm is pivotally attached to the anchoring arm linkage. The first end of the anchoring arm includes a tip portion which defines a slot. The anchoring arm also includes a movable cam inserted into the slot and removably secured to the first end via a first connector pin inserted through an aperture in the cam. According to at least one implementation, the cam is at least partially rotatable about the first connector pin. An exposed portion of the cam is engaged with the surface of borehole wall. When a failure of retraction of the anchoring arm is detected, the cam may be caused to rotate against the borehole wall surface in response. The rotation of the cam against the borehole wall surface causes a force to be exerted upon the weakpoint mechanism, which, in turn, causes the weakpoint mechanism to break. The breaking of the weakpoint mechanism results in a release of the borehole seismic acquisition tool from the stuck position. According to a specific embodiment, rotation of the cam against the borehole wall surface may be caused by a pulling force applied to a top portion of the borehole seismic acquisition tool.
