SUMMARY:Technical Happy Hour- Completions
DESCRIPTION:Host: Society of Petroleum Engineers\, Denver Section \nEvent: March 2025 Technical Happy Hour \nTime: March 27th\, 4-6 (HH begins at 4\, Talk at 430\, Social until 6) \nLocation:  Liberty Energy\, 950 17th St\, Suite 2400\, Denver\, CO 80202 \nSponsor: Liberty \nStudy Group Category: Completion \nSpeaker: Robert Holman\, Geophysicist\, Ovintiv \nTitle: Fracture Growth Through Microseismic Quiescent Zones: Indication Of Stealth Or Complex Fracturing? \nAbstract: \nOften microseismicity levels tend to vary from one lithological unit to the next\, with some layers being predominantly quiet and lack any microseismicity. Since shear activated deformation associated with microseismicity will depend on the geomechanical properties and natural fabric of the formation\, the lack of microseisms in certain layers may or may not be indicative of a change in the hydraulic fracture geometry. In this work\, microseismic observations are integrated with strain and other observations to investigate the microseismic response in relation to the underlying hydraulic fracture geometry for different rock types. The combined conclusions allow identification of two distinct types of response for aseismic layers. The first type are ‘stealth’ homogeneous layers that behave aseismically with the lack of natural fabric to host shear activated microseisms from consistent fracture growth. The second type are interbedded shaly layers where the lack of microseismicity is associated with fracture complexity that results in compartmentalized portions of the hydraulic fracture which may not effectively drain the reservoir. Examples are described of these types from integrated monitoring of hydraulic fracture growth in Uinta Basin\, Utah and Midland Basin\, Texas. \nBio: \nRobert Holman has been a geophysicist at Ovintiv in Denver for two years. As a member of the reservoir characterization group\, he enhances the company’s understanding of the Permian Basin. In his role\, he integrates seismic data into operational processes and regional characterization\, as well as diagnostic interpretation\, to enhance understanding of subsurface features and optimize field performance.  Before joining Ovintiv\, he worked 10 years at Chesapeake Energy\, now known as Expand. While working there he gained experience through his role as a geophysicist in their Eagle Ford asset and technology team\, where he contributed to various projects aimed at improving operational efficiency and implementing technology. He earned his B.S at BYU-Idaho and M.S. at Oklahoma State University. \n  \nRegister Here
