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.
Hydraulic fracturing holds great potential in the region, but there are several key questions worth asking as efforts move forward.
-
Production from an offshore Angola field has been decreasing because of subsea pressure declines amid water-cut increases and limited gas compressor capacity. The development process leading to the selection of high-boosting multiphase pumps is described. -
Experimentation reveals that swellable nanogels increase their size faster than expected or produce aggregation leading to serious blocking problems at the sandface. This paper studies if the addition of a surfactant can help improve injectivity.
-
An ensemble-based 4D-seismic history-matching case is presented in the complete paper. Seismic data are reparameterized as distance to a 4D anomaly front and assimilated with production data.
-
In the complete paper, the authors propose a novel method to rapidly update the prediction S-curves given early production data without performing additional simulations or model updates after the data come in.
-
The aim of this work is to present the effectiveness of a fully integrated approach for ensemble-based history matching on a complex real-field application.
-
One unfortunate consequence of a base-case model, however, is the risk of an anchoring effect, in which case we may underestimate uncertainty. Essentially, the anchoring effect refers to our tendency to rely too heavily on the information offered, introducing a bias in the model-construction process

Big-data mining techniques can help determe the type-curves and the resulting estimated ultimate recovery of an asset being evaluated for acquisition.

Producers in Oklahoma’s newly opened Merge play are sitting atop a resource that rivals some major world gas fields and discoveries, Citizen Energy’s Geology CEO Greg Augsburger told the SPE Gulf Coast Section Business Development Group recently.
-
Indy Chakrabarti, senior vice president of product management and strategy at Emerson Automation Solutions talks about developments in software solutions for the oil and gas industry.

In the onshore world, one of the big advances for addressing increased sampling requirements has been to go to 24-hour shooting with continuous recording of simultaneously sweeping vibrators. This has been enabled by innovations in both acquisition and processing.
