We must be sure that our perspectives have a solid foundation of facts, supported by other research and explained in a true, unbiased manner that can stand up to scrutiny from other scientists and the public.

The Eagle Ford shale play in South Texas emerged as a leading unconventional prospect even as oil and gas prices crumbled, making it one of the few promising U.S. production prospects in today’s price environment.

The Carbonate Depositional Systems course is an excellent introductory course that assumes no pre-existing knowledge. It is designed for earth scientists and engineers involved in exploration or production from carbonate rocks. It moves from basic principles to advanced ideas and case studies that will also help experienced geoscientists with practical aspects of carbonate depositional systems.

Where is the oil? How much is there? and What is the best strategy for recovery? These are a few of the questions that we'll answer at the Making Money with Mature Fields - Geosciences Technology Workshop, October 5-6, 2016, Houston, TX. The goal of this workshop is to review mature fields and to identify the amount and nature of oil that can be recovered, and to evaluate competing strategies for economically producing the remaining reserves. In addition to looking closely at fields, we will review new and improved technologies that may help revitalize reservoirs and overcome problems such as low pressure, paraffin, corrosion, and more.

Given the high profile of U.S. shale production, it’s easy to forget this phenomenon kicked off a mere decade ago, give or take. As the number of shale oil and gas plays proliferated, so did the naysayers. The negative predictions focused on the well-known rapid decline in production that occurs once these wells go online. Instead of an early death, the ensuing boom upset the world order in oil production.

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.

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.

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.

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.

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.
