Looking at a formation as a source rock, then turning around and considering it a viable reservoir requires you to be able to shift your thinking and to analyze a great deal of data in a new way. If you don’t, you risk not understanding the nature of “sweet spots” and how to accurately complete or use reservoir characterization studies.

I find it ironic that George Mitchell, the “father of hydraulic fracturing technology” (aka, “father of fracing”), a technology that so many people fear or hate because of its perceived negative environmental impact, was so passionate about the environment and sustainability. This is a message we need to convey.

The second annual Unconventional Resources Technology Conference, which once again threw a multidiscipline spotlight on new approaches, technology and science being used to develop unconventional plays, attracted more than 5,000 attendees– a 25 percent increase over last year’s inaugural event – to Denver’s Colorado Convention Center in late August.

During my recent 11-country AAPG Distinguished Lecture tour in Europe I had many requests for “The Environmental Realities of Hydraulic Fracturing: Fact versus Fiction,” an analysis of the root causes of the global pushback against hydraulic fracturing, commonly known as “fracking.” Central causes of public fear arose in America because of a combination of early mistakes by industry and purposeful disinformation from activists and others seeking to profit from such mistakes.

It was a collective sigh of relief heard ‘round the state. Two months ago, Colorado Gov. John W. Hickenlooper managed to pull off what many call the compromise of the season – the political season, that is, in a state that has been dragged into a months-long, messy battle between the oil and gas industry and politicians and activists who oppose drilling on various levels.

Recent announcements have positioned the Springer Shale as a potentially prolific producer at 12,500 ft depth, with Continental Resource’s initial tests producing more than 2,000 barrels per day.The Springer, which is a Mississippian-Pennsylvanian boundary zone formation has been an important oil and gas producer in both southern Oklahoma and in the Anadarko Basin.

The Granite Wash of the Anadarko Basin of Oklahoma and Texas has been a remarkable challenge with prolific results for operators who have solved the mystery of a highly complex play. With up to 18 producing zones, extreme compartmentalization, and pressures that can be challenging, all phases of exploration, drilling, and production require special knowledge.

Virtual Workshop
Tuesday, 25 January Wednesday, 26 January 2022, 8:00 a.m.–5:00 p.m.

This two-day virtual conference aims to bring together industrial and academic persons to present, explore and develop approaches that will benefit both sectors in the future. The virtual conference will focus on current techniques, the challenges and future solutions in understanding the Triassic stratigraphy of the North Sea, Norwegian Sea, West of Shetland, Atlantic margins, and northern Europe.

VG Abstract

Microseismicity induced by hydraulic fracture stimulation of a horizontal well was mapped with a near-surface buried array. Distinct linear trends of events were not parallel to the direction of fast shear wave polarization measured in the reservoir with a crossed-dipole anisotropy tool. Analysis of core from a nearby well revealed numerous calcite-filled fractures that did not induce shear wave polarization, but did significantly impact the failure behavior of the reservoir rock during the stimulation treatment. Hydraulic fracture simulation with DFN modeling and source mechanism analysis supports the interpretation of reactivated existing fractures rather than the formation of hydraulically-induced tensile fractures.

Hydraulic fracturing has been around for decades. This talk describes some of the first applications of the technology, how it developed over time, and our current understanding of its impacts with some discussion of both water and earthquake hazards.

VG Abstract

Analysis of microseismicity induced by hydraulic fracture stimulation in the Marcellus Shale shows changes in stress state for different zones of failure. During the treatment, shear failure occurs on both the J1 and J2 fracture orientations in response to different maximum stress orientations, indicating localized changes in the orientation during the treatment. Reactivation of a fault near the wellbore is associated with failure mechanisms with a higher volumetric component, indicating possible inflation of faults and fractures by the introduction of the slurry. Quantification of the stress conditions that are associated with inflation could potentially be used to optimize the stimulation by identifying which fractures will preferentially take on slurry volume.

This is a less-technical education topic. It can be condensed to an hour or given as 2 two-hour sessions. It stresses selected controversial aspects of fracking that touch some combination of environment and economics and includes a short video of how fracking is done.
