Utah FORGE Applies Unconventional Resource Methods for Geothermal Research

New ground-breaking advances are currently being made at the Utah Frontier Observatory for Research in Geothermal Energy using methods borrowed from the oil and gas industry for unconventional hydrocarbon development. Recently, geothermal history was made when Utah FORGE successfully completed the first of two highly deviated deep wells in the hot, hard granite that will form the geothermal reservoir.

Always Pay Attention to the Really Big Things

If you remember from my last column, this is a three-part series on my thoughts on science, membership and budget. I talked about budget last time … we are still working on it, so let’s talk science. The reason most professionals join AAPG is for access to science. That’s not just my opinion – it’s what members tell us. AAPG is very good about disseminating the work of our members and other professionals around the world. That’s our mission.

Using Shale Capacity to Predict Well Performance Variability: Part 2

As discussed in part 1 of this article, when it comes to the attributes used in equation 1 for seismically determining shale capacity, it is difficult to make a manual choice for the cut off values. To alleviate such a problem, application of machine learning techniques could be useful and thus worth exploring.

Shale Capacity for Predicting Well Performance Variability

The goal of reservoir characterization work carried out for a shale play is to enhance hydrocarbon production by identifying the favorable drilling targets. The drilling operators have the perception that in organic-rich shale formations, horizontal wells can be drilled anywhere, in any direction, and hydraulic fracturing at regular intervals along the length of the laterals can then lead to better production. Given that this understanding holds true, all fracturing stages are expected to contribute impartially to the production. However, studies have shown that only 50 percent of the fracturing stages contribute to overall production. This suggests that repetitive drilling of wells and their completions without attention to their placement must be avoided, and smart drilling needs to be followed by operators.

Call for Papers

Challenges related to the energy transition have led scientists to seek the ways and means to sequester carbon dioxide. Use of CO2 injection to enhance oil recovery from existing fields and CO2 storage in depleted oil and gas fields provide obvious opportunities for CO2 sequestration. As well as the interest in existing fields, there has been a significant drive to identify potential storage sites in recent years, as well as in the larger saline aquifers in which they are situated.

Geomechanical Modeling Facilitates Better Production, Safer Drilling

Considering that success or failure of unconventional exploration is largely dependent on drilling horizontal wells in the right area and fracturing efficiently, and considering also that geomechanical modeling facilitates these processes, it is easy to see that when industry professionals have a better perspective of the subsurface mechanics, the better chance they have for increased production. That is the point of geomechanical modeling: safer drilling and increased production.

The Importance of Fracture Toughness

Shale resource plays are associated with low permeability, so hydraulic fracturing is required for their stimulation and production. In order to enhance the flow of fluids with hydraulic fracturing, it is vital to understand the stress field distribution. The efficiency and effectiveness of a hydraulic fracture stimulation are predicated on adequate horizontal well placement in the subsurface. For that purpose, the horizontal wells are usually drilled in the direction of minimal horizontal stress so that hydraulic fracturing takes place in the direction of maximal stress that ensures better reservoir contact and production, which also depends on how a complex fracture network is created by induced fractures.

Petroleum Geologists and DEG Can Pave the Way for CCUS

The maturing carbon market is a major driver for carbon capture, utilization and storage projects. Both the subsurface technical knowledge and related data sets of the petroleum industry are major inputs required for the world to successfully move toward a carbon-neutral and sustainable energy future. To that end, one of the goals of the Division of Environmental Geosciences in representing AAPG is to promote what petroleum geologists can offer during an evolving energy future.

Lawmakers, Candidates Propose Nationwide Ban on Hydraulic Fracturing

Proposals to ban hydraulic fracturing in the United States have drawn a wide range of responses from analysts, with projected effects ranging from cataclysmic to trifling. Legislation to phase out fracturing was introduced in both the U.S. Senate and House of Representatives earlier this year. That turned up the heat on the controversy, as did the emergence of Sen. Bernie Sanders as the frontrunner for the Democratic presidential nomination. Sanders and Sen. Jeff Merkley introduced a bill titled the “Ban Fracking Act” in January.

Evaporite Processes and Systems: Integrating Perspectives

Join us in Salzburg, the “castle of salt” and cradle of Mozart and Doppler, for a meeting aimed at bringing together different perspectives in the science of evaporite basins: from their formation to their deformation, from description and characterization to modelling. Exploratory success in evaporite-rich basins worldwide has depended on the role of evaporites as a deformable substrate, as a seal, or even as a good thermal conductor. The aim of this workshop is to improve our understanding and predictive ability by addressing evaporite systems in an integrated manner, all the way from precipitation to structuration, and exploring the multiple properties of evaporite sequences. The pre- and post-meeting field trips will also explore the salt mining heritage of the region, first exploited by the Celts 3500 years ago, and the salt-related structures of the Northern Calcareous Alps.

Induced Hydraulic Fractures or Reactivated Natural Fractures?

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.

Fracture Mechanics Interpreted from Stress Inversion Analysis on Microseismic Event Source Mechanisms in the Marcellus Shale

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.
