Formation evaluation
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.
This paper presents a novel approach to predict reservoir porosity by conditioning seismic data, calibrating seismic impedance inversion, and tailoring rock-physics analysis.
Smart Seismic Solutions plans to use 50,000 nodes to examine storage potential for the Greenstore CCS project.

Individually and collectively, we are currently facing undeniable difficult times. But, as has been said, challenges are also opportunities. It is a proper time for all of us to pause a bit and formulate way-forward plans that suit our needs. -
A well was drilled into a prospective unconventional mudstone play offshore Norway. Two of five coring runs were successful while the rest yielded little to no core recovery. Subsequent investigation of the core substantiated that the coring issues largely had natural causes.

This paper introduces a new core-analysis work flow for determining resistivity index (RI), formation factor (FF), and other petrophysical properties directly from an as-received (AR) set of core samples.

Formation evaluation drew special attention at the 2019 International Petroleum Technology Conference Education Week in Beijing, 24–28 March 2019. The student team that worked on Integrated Formation Evaluation for Resources Exploration and Reservoir Delineation won the first-place award.

What effects will Industrial Revolution 4.0 have on the upstream oil and gas businesses in general and petrophysics in particular? We should see more intelligence and automation in measurements, processes, work flows, and operations.
-
This paper bridges the gap between operational petrophysicists and FTS specialists, introducing an automated work flow by which petrophysicists can conduct FTS jobs.
-
The complete paper presents different methods of using pressure-transient data from WFTs; many of these methods are summarized here.
-
Schlumberger’s new multifunction spectroscopy system builds on previous innovations to offer the first complete cased-hole formation evaluation and reservoir saturation monitoring capability that provides openhole-equivalent logging measurements.
-
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.
-
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.
