Unconventional/complex reservoirs
A Chinese operator in the Sichuan Basin used high‑frequency pressure monitoring to evaluate frac performance in unconventional wells.
Acting director of the new center Ale Hakala outlines the research priorities guiding the newly established center’s focus on production enhancement technologies.
Operators aren’t rushing to drill, even as the closure of the Strait of Hormuz drives oil prices up.

This work proposes a method to interpret far-field strain-change and pressure data to quantify fracture connectivity and properties at the cluster level. -
The authors of this paper describe a method of stimulating a multizone hydrocarbon-producing well wherein a tool is deployed downhole by wireline to generate acid vapor at a target depth, allowing each interval to be treated uniquely.
-
This paper extends an integrated two-scale continuum model that contemplates mass, momentum, and energy changes to study the acid-stimulation process in complex carbonate acid-stimulation systems with the development of fracture and vug networks.
-
The authors of this paper write that autonomous outflow-control devices can positively affect matrix acidizing by providing the best possible conformance.
