Unconventional/complex reservoirs

The key element of hydraulic-fracture modeling is the prediction of the generated fracture geometries. Research conducted over the years has trickled down predictive software. Nevertheless, the ability to design optimal fracture treatments is hampered, as we cannot “see” the subsurface.

In this work, novel physics-based models and machine-learning models are presented and compared for estimating permanent-downhole-gauge measurements.

For those with an oil company to sell, an oil price of $100/bbl is not what it used to be.

Chevron assets in Texas and Colorado have earned high marks for control of methane emissions under a pilot program with Project Canary, paving the way for its sale of responsibly sourced gas.

The paper investigates estimation of optimal design variables that maximize net present value for life-cycle production optimization during a single-well CO2 huff ‘n’ puff process in unconventional oil reservoirs.

Unconventional resource exploitation has three key technology and application focus areas—increasing implementation of fracture diagnostics, enhancing production and recovery from new well completions as well as existing wells through improved stimulation and restimulation design and execution quality, and developing enhanced oil recovery methods.

This paper illustrates efforts undertaken to evaluate high-viscosity friction reducers and crosslinked gel products, their successful field application, and the importance of maintaining an effective field/laboratory/field cycle.

A study of a limited number of decommissioned oil and gas wells in England found no evidence of methane leaks, including four wells found to be leaking in an earlier study.

Whitecap enters into the liquids-rich Duvernay play, including 74,000 acres with more than 250 identified drilling locations.

Another day, another deal for ProFrac.
