Abstract: A perforating system having a perforating gun with a tubular gun housing defining an inner volume and extending in an axial direction. A shaped charge is held in a loading tube. The loading tube is located in the gun housing. The loading tube extends along the axial direction. The shaped charge faces in a firing direction substantially perpendicular to the axial direction. A portion of the gun housing adjacent to the shaped charge in the firing direction is a perforating portion for removal upon firing of the shaped charge. An eccentralizer member extends from the perforating gun in a second direction that is substantially opposite and parallel with the firing direction. A first retainer part extends from an outer surface of the gun housing adjacent to the perforating portion. A second retainer part extends from the outside of the gun housing adjacent to the perforating portion.

Abstract: For optimizing well production, intervals are selected along a deviated wellbore, and a well test and treatment string is deployed in the wellbore. Each interval is then isolated to enable performance of desired testing. The test data obtained is evaluated to determine an appropriate remedial action which is then implemented via the well test and treatment string. The system and method enable the testing and treatment of a plurality of intervals along a horizontal well during the same run downhole.

Abstract: An apparatus for use in a wellbore includes a tool string and a plurality of sensors, which include at least a first sensor to detect pressure signals in an inner conduit of the tool string and at least a second sensor to detect pressure signals in an annulus outside the tool string. A controller actuates a tool in the tool string in response to a logical combination of outputs from the sensors, where the outputs of the sensors are responsive to the respective pressure signals.

Abstract: The invention relates to fluid sampling in a test that is used to determine physical and chemical characteristics of the fluids in a subterranean reservoir. The method reconstructs the entire pressure history of the fluid parcel that is captured in the fluid samplers during a test. Using this reconstructed pressure history of the samples, the quality of the samples, particularly, whether there is a phase change in the samples during the test, can be accurately quantified.

Abstract: Based on measurements that are obtained from a well test, a pressure in the well is modeled as a function of at least a skin effect factor that varies with time. The results of the modeling may be used to estimate at least one well parameter, such as a formation parameter and/or a well pressure, as examples.
