Reservoir
In a study that applied alternative carbon carrier technology to enhanced oil recovery (EOR) scenarios, researchers at The University of Texas at Austin found that the new method recovered up to 19.5% more oil and stored up to 17.5% more carbon than conventional EOR methods.
This paper presents a novel methodology for assessing the rapid mineral carbonation of carbon dioxide through geochemical interactions with carbon-, magnesium-, and iron-rich minerals abundant in geological formations.
This study assesses the advantages, constraints, and necessary enhancements of both passive and active electromagnetic techniques in the context of carbon capture and storage.

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 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.

Interface Fluidics carved out a niche for itself in the oilfield testing sector a few years ago with a new alternative to coreflooding. Now, along with Equinor, the Calgary-based company is taking on another industry laboratory stalwart: the slimtube test.
-
The authors introduce and compare two quality-control approaches based on two different signal-processing practices.
-
Innovators at the Norwegian oil company have developed a machine-learning model that analyzes mud-gas data to predict the gas/oil ratio of wells as they are drilled—something that the industry has worked for decades to accomplish.
-
As I reviewed all the SPE seismic papers this time, the most noticeable thing was the diversity of themes and case histories that were covered.

In striving to boost production of shale gas and tight oil, China is trying enhanced-hydraulic-fracturing technology and real-time data analysis in the Sichuan shale basin. In Daqing’s tight-oil fields, an alternative fracture-completion strategy and post-stimulation flowback technology has been tested.
