Patent number: 10329855Abstract: A control line assembly and technique for fabricating the control line assembly are disclosed. The assembly includes drawn tubular segments through which a gas is flowed to purge contaminants. The outflow of contaminants due to the gas flow is monitored and the gas flow can be controlled and terminated when a sufficient quantity of contaminants has been extracted. The gas flow can be combined with a heat treatment cycle to further extract contaminants. The heat treatment cycle can include multiple heating stages that can be controlled based on the monitoring of the exiting contaminants.Type: GrantFiled: December 5, 2014Date of Patent: June 25, 2019Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Dominic Joseph Brady, Gary Oddie

Patent number: 10301934Abstract: A downhole densitometer is used to determine one or more characteristics of a flowing fluid. The densitometer has one or more downhole x-ray sources and one or more downhole x-ray detectors. A fluid is allowed to flow past the x-ray sources. X-rays emitted by the x-ray sources and that have travelled through the flowing fluid are detected by the x-ray detectors. Characteristics of the flowing fluid are determined based on the detected x-rays. The densitometer may also have reference detectors used to measure a reference signal. The measured reference signal is used to normalize source emissions. The densitometer may be used as a permanent monitor and it may be used in conjunction with other sensors such as a flow-rate sensor or a capacitance sensor. The x-ray source may be, for example, a pyroelectric source, a radioisotopic source, or a traditional x-ray tube source.Type: GrantFiled: March 19, 2015Date of Patent: May 28, 2019Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Dominic Joseph Brady, Reza Taherian, Gary Oddie, Christian Stoller

Patent number: 7717000Abstract: A method of sampling a multi-phase fluid stream is provided which comprises the steps of: sampling, with a sampling probe, a portion of the fluid stream; measuring the flow rate of said sampled portion; and measuring, independently of the sampling step, the total flow rate of the fluid stream, wherein the flow rate of the sampled portion is controlled according to the ratio of the flow rate of the sampled portion to the flow rate of the fluid stream, in order to obtain substantially isokinetic sampling of the fluid stream. The method may provide isokinetic sampling to an accuracy of 5% or less and preferably only samples a small portion of the fluid stream. The method has particular application for high rate condensate gas wells. A corresponding sampling system is provided which has particular application in the sampling of streams from well-heads.Type: GrantFiled: September 9, 2004Date of Patent: May 18, 2010Assignee: Schlumberger Technology CorporationInventors: Cheng-gang Xie, Ian Atkinson, Paul Hammond, Gary Oddie, Paul Bolchover
