Formation evaluation
Imaging carbonate rocks at high resolution without losing scale has long been a challenge. A novel framework is introduced that enables accurate super-resolution and extrapolation of carbonate rock images, enhancing micro-CT images while preserving mineralogical and topological features for more reliable pore-scale analysis and flow simulations.
This paper presents an experiment investigating dissolution of basaltic primary minerals and conditions favorable for secondary phase formation under deep subsurface storage conditions.
As several commercial-scale projects are gearing up in the US, developers expect the next few years to reveal whether lithium extraction from brines can become a big business.

Emerging technologies have helped bring about multilateral, maximum-contact, and smart-completion wells, allowing reservoirs to be developed and produced much more efficiently and economically. In this, formation evaluation plays a critical role. -
Coalbed methane development can require a large volume of wells, but the costs of logging can be prohibitive, so alternate formation-evaluation solutions are being evaluated. This paper compares state-of-the-art mining logging technology with conventional oil-and-gas approaches.
-
To do more with less, standardization and automation will be key. Application of techniques honed in other industries need to be evaluated as part of the path toward standardized approaches.
-
Recent experience with a newly introduced sampling-while-drilling service has shown that it is possible to make reliable downhole formation-fluid-property estimates during sampling-while-drilling operations.
-
Comprehensive formation evaluation is one of the technical focus areas that is fundamental across almost all upstream businesses.
-
Any oil and gas deal usually involves a data room, where rich seams of proprietary information can be mined for a limited period.

When interviewing potential senior-petrophysicist recruits, we exchange pleasantries to break the ice and then I ask an easy, yet fundamental technical question: “How would you explain Archie’s law to an inexperienced colleague?” Then, I sit back in expectation of a slick answer from the candidate. Imagine my surprise when the interviewee takes a sharp intake of breat…

The variable data quality of core analysis, the sensitivity of results to different test methods, poor reporting standards, and the reluctance of some vendors to share experience and expertise have contributed to basic mistakes and poor data quality.

Exploration wells, unconventional plays, and development wells can benefit from NeoScope, a sourceless formation evaluation-while-drilling solution. Two case studies share how the technology mitigates the risks or logistic complications associated with chemical nuclear sources.
