摘要： A technique facilitates performance of a perforating operation in a wellbore. The technique comprises positioning a perforating gun assembly downhole in a wellbore via coiled tubing. The perforating gun assembly has a plurality of individually controllable perforating gun sections which may be selectively fired at different well zones. An optical fiber is deployed along the coiled tubing to deliver control signals to the perforating gun assembly. The control signals enable sequential firing of the individually controllable perforating gun sections at the desired locations, e.g. well zones, along the wellbore.

摘要： A sample module for a sampling while drilling tool includes a sample fluid flowline operatively connectable between a sample chamber and an inlet, for passing a downhole fluid. A primary piston divides the sample chamber into a sample volume and a buffer volume and includes a first face in fluid communication with the sample volume and a second face in fluid communication with the buffer volume. An agitator is disposed in the sample volume for agitating the sample fluid. A secondary piston includes a first face in fluid communication with the buffer volume having buffer fluid disposed therein and a second face.

摘要： A sample module (SM) for use in a downhole tool includes a sample chamber for receiving and storing pressurized fluid. A piston (112) is slidably disposed in the chamber to define a sample cavity (110c) and a buffer cavity (110p), and the cavities have variable volumes determined by movement of the piston (112). A first flowline (54) is provided for communicating fluid obtained from a subsurface formation through the sample module. A second flowline (114) connects the first flowline to the sample cavity, and a third flowline (116) connects the sample cavity to one of the first flowline and an outlet port. A first valve (118) is disposed in the second flowline (114) for controlling the flow of fluid from the first flowline (54) to the sample cavity (110c), and a second valve (120) is disposed in the third flowline (116) for controlling the flow of fluid out of the sample cavity (110c), whereby any fluid preloaded in the sample cavity may be flushed therefrom using the formation fluid in the first flowline (54) and the first (118) and second (120) valves.

摘要： A sample module for a sampling while drilling tool (230) includes a sample fluid flowline (310) operatively connectable between a sample chamber and an inlet (1206), for passing a downhole fluid. A primary piston (1214) divides the sample chamber into a sample volume (1230) and a buffer volume (1232) and includes a first face (1218) in fluid communication with the sample volume (1230) and a second face (1220) in fluid communication with the buffer volume (1232). A secondary piston (1222) includes a first face (1226) in fluid communication with the buffer volume (1232) having buffer fluid disposed therein and a second face (1228).

摘要： A system and method to facilitate connection of completion assemblies at a downhole location. A completion assembly 28 comprises a control line conduit 44 having a connector 46 designed for coupling with a corresponding connector 34 of a next adjacent completion assembly 26. A cover 52 is selectively used to block entry of debris and other contaminants into the connector 46 during deployment of the completion assembly 28 downhole prior to engagement with the next adjacent completion assembly 26.
