Heloise Bloxsom Lynn is a geophysical consultant and instructor with Petroskills and Nautilus World. She started working in seismic reflection data in 1975, processing U.S. onshore data for Texaco in Houston. Lynn worked for Texaco, Amoco, BP, and then in 1984, she and her husband, Walt, formed Lynn Incorporated. Her consulting experience includes working in North America, Hungary, Qatar, Kuwait, Saudi Arabia, Pakistan, Australia, Thailand, China, and Japan. She specializes in the use of 3D multiazimuth and/or multicomponent data to obtain structure, lithology, porosity, pore fluids, in-situ stress, and aligned porosity (aka natural fractures). She also includes conventional VSP data processed for split-shear waves in these projects because there is nearly always a source-generated S-wave or a near-source mode-converted S-wave, and/or mode-conversions at impedance boundaries. In the fall of 2004, she was the SEG/AAPG Distinguished Lecturer, speaking on “The Winds of Change – anisotropic rocks, their preferred direction of fluid flow, and their associated seismic signatures.” 2014 brought an Honorable Mention, Best Paper, SEG Annual Meeting to H. Lynn, W. Lynn, J. Obilo, V. Agarwall, “Azimuthal prestack depth migration for in-situ stress evaluation, in a fractured carbonate oil reservoir: predrill prediction of instantaneous shut-in pressure gradients.” A 2015 SEG award citation: “Heloise Lynn was presented the Reginald Fessenden Award for her 35-year career of translating the anisotropic behavior of seismic waves into practical applications that allow stress fields, fracture systems, and geomechanical properties to be characterized in targeted rock systems. She has described her research findings in many oral presentations and in 47 published papers that collectively create an invaluable knowledge base for scientists, researchers, students, teachers, and exploration geophysicists.” In 2016, she presented the Geophysical Society of Houston webinar, “Applied Azimuthal Anisotropy - Azimuthal 3D P-P Seismic: Why Bother?” In 2017, she was invited back to present “Basics and Updates on Anisotropy: Azimuthal P-P for Better Imaging, Fractures & Stress Analysis -- Acquisition, Processing & Interpretation.” Both webinars are available through SEG. She earned a BA in geology-math from Bowdoin College, Maine; an MSc in exploration geophysics from Stanford University; and a PhD in geophysics from Stanford University. She is a member of SEG, EAGE, the Geophysical Society of Houston (GSH), AAPG, and SPE.
