Reservoir
Operators aren’t rushing to drill, even as the closure of the Strait of Hormuz drives oil prices up.
The authors write that deployment of artificial-intelligence-based high-gas/oil ratio well-control technology enabled stabilization of well performance and maintenance of optimal production conditions.
The paper describes the revalidation of a deepwater prospect that resulted in a no-drill decision.

This paper proposes a framework based on proxies and rejection sampling (filtering) to perform multiple history-matching runs with a manageable number of reservoir simulations. -
This paper provides a more straightforward method for estimating stress-dependent permeability and capillary pressure in rock fractures.
-
In hydraulic fracturing, the use of diagnostic-fracture-injection tests (DFITs) can provide valuable information.
-
At the recent 2015 Unconventional Resources Technology Conference, a major theme was how companies can improve performance without increasing the size of their budget.
-
The label unconventional oil and gas stubbornly hangs on because these formations cannot be understood using the rules of conventional petroleum engineering.
-
The authors discuss the results of a pilot project to capture post-combustion CO2 for purposes of EOR.
-
Produced water from chemical floods can cause problems for separation and water treatment equipment due to the polymers and surfactants used. Challenges are greater offshore where space limitations can affect treatment options.
-
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.
-
This work demonstrates that molecular diffusion may be a viable oil-recovery mechanism in fractured reservoirs during injection of carbon dioxide (CO2) for enhanced oil recovery (EOR).
