An Overview of Microseismic Imaging of Hydraulic Fracturing
This 2-day course is a survey of microseismic imaging of hydraulic fracturing. It is designed to give the attendees a rudimentary understanding of this technology based on the science at its foundation, the means and methods by which it is carried out, and the benefits it brings to the users. Since this technology is interdisciplinary, combining geophysics, geology, and geomechanics with well completion technologies, the goal of the course is to give attendees the knowledge and realistic expectations of microseismic imaging of hydraulic fracturing. To this end, attendees should expect to become knowledgeable and discerning users, evaluators, and questioners of those vending this technology.
- How it began—colliding disciplines: hydraulic fracturing technology meets pressure-induced microseismicity
- Overview of material science, geomechanics, rock mechanics, fracture mechanics, and geology
- Technology of hydraulic fracture stimulations
- In Situ studies of hydraulic fracturing
- Seismology and microseismology
- Microseismic Imaging—it’s how’s and why’s and more than “dots on a page”
- Case studies, FAQs and misconceptions
- Discussion and Q&A
Why You Should Attend
From its beginning, microseismic imaging of hydraulic fracturing has created controversy. It typically shows a flow network much more complicated than the traditional paradigm of a single, vertical, planar, elliptical fracture. This course is designed to give an understanding of the foundation of the “ground truth” from microseismic imaging data, an appreciation for the implementation and benefits of the technology, and an awareness of the strengths and weaknesses of the technology.
Who Should Attend
Any oil and gas professional interested in hydraulic fracturing and diagnosis would benefit from this 2-day survey course.

Kenneth D. Mahrer is chief scientist at APEX HiPoint, a company specializing in microseismic imaging and evaluating of hydraulic fracturing. His duties center on building the full picture of a hydraulic fracture stimulation. This includes compiling, integrating, evaluating, and interpreting the full complement of data sets: the design and well completion data, the engineering (i.e., injection) data, the logging and petrophysical data, with the microseismic data, and any other germane data (e.g., tracer data).
Mahrer holds BS and MS degrees in physics and a PhD in geophysics from Stanford University. His PhD thesis combined fault modeling with fracture mechanics. Following his PhD, he won two postdoctoral fellowships in fracture mechanics, one at the University of Sheffield (England) and the other at Northwestern University (USA). After these fellowships, he taught geophysics and geology in the geology department at the University of New Mexico, followed by working as a principal geophysicist at Teledyne Geotech. Teledyne Geotech fielded the first team (1980’s) to research, demonstrate, and develop the commercial applicability of microseismic monitoring as a surveillance and diagnostic tool of hydraulic fracture stimulations.
His career has included a diversity of positions including being a member of the team that monitored, mapped, and characterized the microseismicity induced by the world’s deepest, continuous, high-pressure injection well (Paradox Valley, western Colorado, continuous injection since 1996). Prior to coming to APEX HiPoint, Mahrer was a principle geophysicist in the microseismic mapping group at Weatherford International. He has been a technical editor for both the Society of Exploration Geophysicists (SEG) and the Society of Petroleum Engineers. He has written two columns for the SEG journal The Leading Edge: one, “The Writer’s Block", on improving technical writing and one, “Bright Spots”, summarizing technical articles appearing in the SEG journal Geophysics. In addition to teaching courses on microseismic imaging of hydraulic fracturing, Mahrer teaches technical writing short-courses in universities and companies.
