摘要： A perforating gun apparatus comprising a bulkhead connector located between an upper gun body thread and lower gun body thread. The bulkhead connector has seals in sealing arrangement with an upper gun body and a lower gun body with a support sleeve in contact with an inner groove support shoulder on the lower gun body. The support sleeve is radially deformable into the inner groove by a shockwave produced by firing the charges in the lower gun section. The deformation of the support sleeve attenuates the impact of the shockwave on the threaded connection. The bulkhead connector isolates the threaded connection from the pressure spike. The deformed support sleeve attenuates the shockwave from the charges firing in the upper gun section and transfers the resultant force away from the threaded connection.

摘要： The disclosure provides a method of obtaining logging data of subterranean formations and a logging system for doing the same. One example method includes: (1) conveying a logging tool and downhole tractor through a gravity-conveyed section of a borehole, and (2) obtaining logging data from the logging tool during the conveying, wherein the downhole tractor is employed for at least a portion of the obtaining of the logging data. Another example method includes: (1) lowering a logging tool and an open-hole tractor through a gravity conveyed section of an open borehole, (2) raising the logging tool and the open-hole tractor through the gravity conveyed section, (3) obtaining, from the logging tool during the raising, logging data associated with the gravity conveyed section of the open borehole, and (4) employing the open-hole tractor for at least a portion of the raising of the logging tool during the obtaining.

摘要： A method and system for synchronizing downhole tractor and surface winch deployment includes deploying a tractor and deploying wireline from a winch, obtaining readings of wireline tension, and adjusting the speed of the tractor to match the winch speed. If the tractor and winch speeds appear substantially matched, periodically adding and/or removing slack in the wireline while observing the wireline tension can confirm if the tractor and winch are still synchronized.

摘要： Certain aspects and features of the present disclosure relate to an automated system for assessing pumpoff risk, which can be used to warn operators and/or control machinery in order to avoid pumpoff. Pumpoff risk is assessed through the use and/or comparison of one or more models of pumpoff risk. These models can include a sand build up model (e.g., to determine the threshold buildup size where pumpoff risk is too great), a line speed increase model (e.g., to determine the maximum flow rate allowable given a maximum support line feed rate), a residual error comparison model (e.g., to compare the deviation of predicted tension from actual tension), and a statistical analysis model (e.g., to determine likelihood of pumpoff given statistical probability of each of a multitude of possible scenarios).

摘要： At least one crack designator for a perforating gun, wherein the gun includes a longitudinal direction, a lateral direction, and at least one scallop, wherein each crack designator is capable of redirecting crack growth from the lateral direction to the longitudinal direction of the gun. The designator may be located in one of the scallops, extend from an expected exit hole in the gun to an edge of one of the scallops, and be capable of redirecting crack growth from a lateral direction to a longitudinal direction of the gun. In preferred embodiments, the designator in each scallop is arranged in a spider pattern or concentric circles. The designator is preferably formed by machining, etching, or laser ablation. The designator may have a lower fracture toughness or lesser stiffness than surrounding material of the gun.
