  • Patent number: 11118445
    Abstract: A system for improving communication between surface and downhole equipment, in some embodiments, comprises: a first transceiver in a formation; a second transceiver in the formation; and a third transceiver in the formation, the second transceiver positioned between the first and third transceivers, wherein, upon determining that a communication quality metric pertaining to wireless communication in the formation fails to meet a criterion, the first transceiver transmits data to the second transceiver, wherein, upon determining that said communication quality metric meets the criterion, the first transceiver transmits said data to the third transceiver in lieu of transmitting said data to the second transceiver.

  • Publication number: 20180340419
    Abstract: A method includes deploying a fluid sampling tool string downhole, the fluid sampling tool string including a control module and a plurality of fluid sampling modules. The method also includes receiving, by the control module, a telemetry signal from a surface interface. The method also includes transmitting, by the control module, a downlink acoustic signal based at least in part on the received telemetry signal. The method also includes initiating a fluid sampling operation, by at least one of the plurality of fluid sampling modules, in response to the downlink acoustic signal.

  • Patent number: 9650885
    Abstract: A system and method to determine and adjust positioning of a subsea test tree (“SSTT”) within a blowout preventer (“BOP”), the system including an SSTT, at least one sensing mechanisms to detect the position of one or more BOP rams and a fluted hanger. Once the assembly is deployed, the ram positions are detected and the position of the fluted hanger is adjusted while deployed to accordingly adjust the spacing between the SSTT and the fluted hanger, thereby eliminating the need of a dummy run. Another system and method improves a dummy run by providing a lightweight joint and dummy hanger deployed on a line (e.g., wireline, slickline, etc.). Through the use of a line and the lightweight of the joint and dummy hanger, the dummy run operation is conducted quickly and efficiently.

  • Patent number: 9598953
    Abstract: A system and method to eliminate the need for a dummy run comprises a logging assembly to detect the position of one or more blow-out preventer (“BOP”) rams and a hang off location. During a logging operation, the logging assembly logs the positions of the BOP rams and wear bushing. The logged positions are then used to determine the correct placement of the subsea test tree (“SSTT”) in relation to its hanger. Thus, the need to perform a dummy run is eliminated because correct placement of the SSTT can be determined during routine logging operations.
