Yates Formation
Numerous surface-felt earthquakes have been spatiotemporally correlated with hydraulic fracturing operations. Because large deformations occur close to hydraulic fractures (HFs), any associated fault reactivation and resulting seismicity must be evaluated within the length scale of the fracture stages and based on precise fault location relative to the simulated rock volumes. To evaluate changes in Coulomb failure stress (CFS) with injection, we conducted fully coupled poroelastic finite-element simulations using a pore-pressure cohesive zone model for the fracture and fault core in combination with a fault-fracture intersection model. The simulations quantify the dependence of CFS and fault reactivation potential on host-rock and fault properties, spacing between fault and HF, and fracturing sequence. We find that fracturing in an anisotropic in-situ stress state does not lead to fault tensile opening but rather dominant shear reactivation through a poroelastic stress disturbance over the fault core ahead of the compressed central stabilized zone. In our simulations, poroelastic stress changes significantly affect fault reactivation in all simulated scenarios of fracturing 50-200 m away from an optimally oriented normal fault. Asymmetric HF growth due to the stress-shadowing effect of adjacent HFs leads to 1.) a larger reactivated fault zone following simultaneous and sequential fracturing of multiple clusters compared to single-cluster fracturing; and 2.) larger unstable area (CFSgt;0.1) over the fault core or higher potential of fault slip following sequential fracturing compared to simultaneous fracturing. The fault reactivation area is further increased for a fault with lower conductivity and with a higher opening-mode fracture toughness of the overlying layer. To reduce the risk of fault reactivation by hydraulic fracturing under reservoir characteristics of the Barnett Shale, the Fort Worth Basin, it is recommended to 1.) conduct simultaneous fracturing instead of sequential; and 2.) to maintain a minimum distance of ~ 200 m for HF operations from known faults.

The Energy Information Administration (EIA) forecasts lower US dry natural gas production for the remainder of the year due in large part to continued lower natural gas prices. Several producers scaled back drilling activities after prices fell to a 3.5-year low in February. EIA expects production levels to remain steady in March from February at just under 104 Bcf/D, then slight declines for the balance of the year. "We do not expect that natural gas production will return to its December 2023 record of 106 Bcf/D during the forecast period," EIA wrote. Production increases to 104 Bcf/D in 2025, driven by expected growth in associated natural gas production in the Permian Basin and growth in LNG export demand."

A new research project from the University of New Mexico (UNM) examined the conditions of the workforce in New Mexico's Permian Basin. Gabriel Sanchez, director of the school's Center for Social Policy, and Shannon Sanchez-Youngman, director of the school's Center for Participatory Research headed the Southeastern New Mexico Oil and Gas Workforce Study. "Our study had two main goals, to identify paths to improve the working conditions of oil and gas workers and to help inform areas in workforce training that should be addressed as the state transitions to clean energy production," Sanchez said. The study, commissioned by the nonprofit Somos Un Pueblo Unido, dove into the quality of life experienced by oil and gas workers in the state's Permian Basin--the majority of whom are Hispanic New Mexicans. This incorporated the past and present conditions and how the influence of clean energy could shift their career plans moving forward.

The industry is now in its second year beyond the COVID-19 pandemic, and the workforce has changed in many ways, but issues facing production performance remain. Major conferences saw 116 submissions from 28 countries, with 64% regarding electrical submersible pumps (ESPs), and 18% and 8% devoted to gas lift and rod lift, respectively. Many of the papers dealt with case history successes. That is all well and good, but it doesn't necessarily drive reader interest if it can't be applied to their asset. The top three papers were selected on the guidelines of clarity of the abstract in addressing the scope, methods/procedures/process, results/observations/conclusions, and novel or additive information.

Intervention-based fiber optics have proved a valuable and cost-effective tool in understanding during-fracturing and post-flowback well and section performance. During-fracturing diagnostics, such as crosswell strain measurements from an offset monitor well, describe where fractures intersect the monitor well and reveal details such as azimuth, fracture-propagation velocity, and activation and reactivation statistics. These critical data points help inform cluster, stage, and well-spacing decision-making.
