The authors develop an innovative machine-learning method to determine salt structures directly from gravity data.

An appropriate work flow of combining suitable advanced technologies can help to overcome the long-standing challenges of sub-basalt imaging.

The oil and gas industry, which had begun showing signs of recovery from a generational downturn, was brought to its knees by the COVID-19 pandemic in 2020. SPE’s technical directors reflect on the pandemic’s impacts and share their outlooks going forward in this annual roundup.

I want to remind everyone reading this column that we in the upstream petroleum sector are very good at what we do. Like Dr. Spock (not Mr. Spock) stated, “You know more than you think you do.”

The interpretation of well tests, combined with petrophysical analysis, formation-test data, and production logs, provided insight into Khuff reservoirs.

Most of today’s equipment and interpretation methods are indeed not new. After all, well testing has been around for nearly a century, resulting in a legacy that may not always look cutting-edge, but these tried-and-true tools were so technologically remarkable that they became staples.

The authors describe challenges that must be overcome to reach the goal of drilling systems automation.

The paper outlines examples from tight gas reservoirs in two fields in which openhole data was unavailable and petrophysical analysis was undertaken using cased-hole data.

The papers explore innovative approaches developed by authors of SPE conference papers toward avoiding data bias, working around the absence of openhole data, and reducing the uncertainty of mass-transport complexes.

The work and the provided methodology provide a significant improvement in facies classification.
