The Geophysical Society of Pittsburgh is a nonprofit organization dedicated to promoting the science of geophysics in the Appalachian Basin. We are an official section of the Society of Exploration Geophysics (SEG). Monthly meetings are generally held from September to May on the first Tuesday of each month at various locations around the Greater Pittsburgh area. However, be sure to check the event calendar as exceptions to this rule occur often. All interested parties are encouraged to attend.

Hilbert Transform of the Distributed Acoustic Sensing (DAS) Fiber Optic Data for the Marcellus Shale

Payam Kavousi
West Virginia University

Abstract: Distributed acoustic sensing (DAS) technology utilizes optical fibers to measure the dynamic strain at all points along the fiber. Fiber optic distributed acoustic sensing (DAS) data is recorded for 28 stages in the MIP-3H gas well in Morgantown, WV.  We calculated two attributes to evaluate vibration frequencies around the fiber during the stimulation; they are calculated on each of the 493 traces for every 30 seconds during the hydraulic fracture stimulation (one SEGY file for every 30 seconds). The first attribute is the energy attribute: a summation of the squared amplitude of the DAS traces. Secondly, the DAS data are transformed into the Hilbert domain to  READ MORE

Biography: Payam Kavousi received his B.S. in Petroleum Engineering (2007) from Petroleum University of Technology in Iran. Then he earned a dual degree M.Sc in Petroleum Engineering and Geophysics (2010) from Petroleum University of Technology in Iran and Institute Francais du Petrole in France, respectively. His PhD research at WVU was focused on reservoir characterization and fluid flow simulation for naturally fractured reservoirs. Afterwards, he started working as a postdoctoral fellow in reservoir engineering and geology at the Marcellus Shale Energy and Environment Laboratory (MSEEL) at WVU. His current research efforts include fiber optic data processing and interpretation, and fluid flow simulation for the MSEEL project.
