Publication number: 20230227759Abstract: A system for processing samples from a body of fluid. The system includes one or more sample bottles for acquiring a sample from the body of fluid. Each sample bottle initially retains a pre-filling fluid. Each sample bottle includes a fluidic inlet port and a bottle outlet port. Each sample bottle has an inlet check valve coupled to the fluidic inlet port, the inlet check valve configured to allow fluid from the body of fluid into a sample bottle via the fluidic inlet port when the pressure difference between the body of fluid and fluid within the sample bottle reaches a threshold. The system further includes at least one pump, the bottle outlet port of each sample bottle selectively coupled to the at least one pump via a different control valve. The at least one pump is configured, in a first configuration, to remove prefilling fluid from each selected sample bottle such that, for each selected sample bottle, the pressure difference threshold is reached and a sample from the body of fluid is acquired.Type: ApplicationFiled: March 23, 2023Publication date: July 20, 2023Inventors: Dan E. Angelescu, Andreas Hausot

Publication number: 20100269579Abstract: A gas separation and detection tool for performing in situ analysis of borehole fluid is described. The tool operates by introducing a reagent to a test sample and causing the resulting mixture to flow through a microfluidic channel where optical testing is performed. The optical testing detects a change in a characteristic of the reagent in response to expose to one or more particular substances in the test sample. The test sample may be borehole fluid, a mixture of borehole fluid and scrubbing fluid subsequently mixed with reagent, a mixture of reagent and gas separated from borehole fluid, or a mixture of scrubbing fluid and gas separated from borehole fluid which is subsequently mixed with reagent. A membrane may be employed to separate one or more target gasses from the borehole fluid.Type: ApplicationFiled: April 22, 2009Publication date: October 28, 2010Applicant: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: JIMMY LAWRENCE, DAN E.

Patent number: 7784330Abstract: A micro-fluidic device and methods for measuring one or more rheologic properties of a fluid. The micro-fluidic device includes a substrate and at least one cover bonded to a surface of the substrate with a fluid channel formed in at least one of the cover or the substrate. Further, the micro-fluidic device includes a first differential pressure gauge that can have a first differential pressure sensor in fluid communication with both a first pressure site and a second pressure site. Further still, the micro-fluidic device includes the first pressure site and the second pressure site that can be spaced apart by a first section of the fluid channel. Also, the micro-fluidic device includes a data processor communicatively coupled to the first differential pressure sensor, so as to receive data generated by the first differential pressure sensor.Type: GrantFiled: October 5, 2007Date of Patent: August 31, 2010Assignee: Schlumberger Technology CorporationInventors: Dan E.
