Publication number: 20150036968Abstract: Methods and systems for effectively sealing a fiber optic line to a pressure gauge device are disclosed. A pressure gauge device has an outer body, a reference volume within the outer body and a pressure sensor having a first side and a second side. The first side of the pressure sensor is exposed to a pressure inlet and the second side of the pressure sensor is exposed to the reference volume. A fiber optic line is coupled to the pressure gauge device using a feedthrough device. The fiber optic line comprises a first fiber optic line portion located within the feedthrough device, a second fiber optic line portion located within the reference volume and a third fiber optic line portion located within a cable located outside the pressure gauge device and coupled to the feed through device. The first fiber optic line portion comprises a first Fiber Bragg Grating (“FBG”).Type: ApplicationFiled: July 30, 2013Publication date: February 5, 2015Applicant: Halliburton Energy Services, Inc.Inventors: Michael Joseph LeBlanc, Etienne Samson, William Neal Gibler

Publication number: 20140326860Abstract: A sensing system includes plurality of sensors along the lengths of input and output optical fibers. Each sensor receives broadband pulses from the input fiber, dynamically senses a plurality of physical parameters in a one-to-one correspondence with a plurality of predefined wavelength bands, and forms signal pulses from the broadband pulses by transmitting only a single wavelength within each wavelength band. Each single wavelength has a dynamically-varying peak wavelength value indicative of the corresponding sensed physical parameter. The signal pulses from the output optical fiber are directed into one or more interferometers, which produce a phase deviation corresponding to each dynamically-varying peak wavelength value.Type: ApplicationFiled: May 2, 2013Publication date: November 6, 2014Applicant: Halliburton Energy Services, Inc.Inventors: Han-Sun Choi, Etienne Samson

Publication number: 20140180592Abstract: Various disclosed distributed acoustic sensing (DAS) based systems and methods include embodiments that process the DAS measurements to detect one or more contrasts in acoustic signatures associated with one or more fluids flowing along a tubing string, and determine positions of the one or more contrasts as a function of time. The detected contrasts may be changes in acoustic signatures arising from one or more of: turbulence, frictional noise, acoustic attenuation, acoustic coupling, resonance frequency, resonance damping, and active noise generation by entrained materials. At least some of the contrasts correspond to interfaces between different fluids such as those that might be pumped during a cementing operation.Type: ApplicationFiled: December 22, 2012Publication date: June 26, 2014Applicant: Halliburton Energy Services, Inc.

Patent number: 8636063Abstract: Various disclosed cement slurry monitoring methods include monitoring one or more parameter of the cement slurry at various positions along the borehole during the curing process and responsively identifying a span over which the slurry extends and whether there are any gaps or voids in that span. At least some system embodiments include a distributed sensing arrangement to provide parameter measurements as a function of position and time during the curing process. A computer analyzes the measurements to determine the span of the cement slurry and whether any gaps exist. Contemplated measurement parameters include temperature, pressure, strain, acoustic spectrum, acoustic coupling, and chemical concentration. Individually or in combination, these measurements can reveal in real time the state of the cement slurry and can enable remedial actions to be taken during or after the curing process if needed to address deficiencies in the annular seal being provided by the cement.Type: GrantFiled: February 16, 2011Date of Patent: January 28, 2014Assignee: Halliburton Energy Services, Inc.Inventors: Kris Ravi, Etienne Samson, John L. Maida, William John Hunter
