Inductive couplers for use in a downhole environment
Benoit Deville,Yann Dufour,Philippe Salamitou,Garcia Jean-Luc,Emmanuel Legendre,Eric Grandgirard,Nicolas Renoux +6 more
TL;DR: In this article, an example inductive coupler for use in a downhole environment includes a body defining a cavity and magnetic material positioned in the cavity, and a metal cover being electrically coupled to the body to form a substantially contiguous electrically conductive surface surrounding the cavity.
Patent
Lower completion communication system integrity check
TL;DR: In this article, a technique for verification of the integrity of a lower completion prior to the deployment of a corresponding upper completion is presented, where a service tool system is removably deployed into the wellbore and comprises a service tools with an interface which interacts with the lower completion.
Patent
A water fraction measuring sensor and method
TL;DR: In this paper, an active probe, a reference probe, and an electronic unit are used to measure water fraction in a fluid mixture flowing in a conductive tubing within a borehole.
Patent
Downhole inductive coupler assemblies
TL;DR: An inductive coupler assembly for use in a downhole environment and related methods are described in this article, where the first and third coils are coupled to a first pair of signal lines and the second and fourth coils are coupling to a second pair of signals.
Patent
Method of dynamically correcting flow rate measurements
TL;DR: In this paper, a flow rate of a fluid flowing in a tube is determined using a flow meter, where the flow meter measures a value related to the flow rate, and a valve is used to control the fluid flowing through the meter.
