Patent number: 9494018Abstract: A completion tool for gravel packing screens incorporates an added position to allow redirection of flow to a signal transmission tool at the needed flow rates to optimize signal to noise ratios by creation of a discrete flow path that channels the desired flow directly to the device and using the production tubing and upper annulus as the balance of the flow circuit. The Smart Collet® has a landing location for this position which is preferably between the circulation and reverse positions of the crossover tool. The wash pipe assembly can have a shifting tool that closes the sleeve over the gravel exit ports for the information transmittal such ports can thereafter remain closed because the gravel packing is complete but for the reversing out of excess gravel which happens above the gravel exit ports.Type: GrantFiled: September 16, 2013Date of Patent: November 15, 2016Assignee: Baker Hughes IncorporatedInventors: Aaron C.

Patent number: 9494010Abstract: A downhole tool having a first packing element and a second packing element configured to synchronically set to selectively hydraulically isolate a portion of the wellbore. The movement of a pin along a j-slot track on a second sleeve sets the second packer in compression and the movement of a pin along a j-slot track on a first sleeve the first packer in tension after the second packer has been set. The j-slot track on the first sleeve has six different pin positions and the j-slot track on the second sleeve has four different pin positions. The pin positions and direction of travel of the j-slot tracks are adapted to permit the synchronized setting of the two packing elements to hydraulically isolate a portion of the wellbore.

Patent number: 9482085Abstract: A system and method are provided for providing electromagnetic (EM) measurement-while-drilling (MWD) telemetry capabilities using an existing mud-pulse MWD tool. An EM tool intercepts the output from the mud-pulse tool and generates an EM signal that mimics a mud-pulse pressure signal. The EM signal is intercepted at the surface by a receiver module that conditions the signal and inputs the signal into the existing pulse tool receiver. Since the EM signal mimics a mud-pulse signal, the pulse tool receiver does not require software or hardware modifications in order to process an EM telemetry mode. The EM tool can be adapted to also provide dual telemetry by incorporating a conventional pressure pulser that would normally be used with the pulse tool.Type: GrantFiled: May 12, 2014Date of Patent: November 1, 2016Assignee: Mostar Directionsl Technologies Inc.Inventors: John Petrovic, Victor Petrovic, Matthew R. White, Neal P. Beaulac
