Case studies from Devon Energy, ConocoPhillips, and others show how clever engineering and technology are being used to improve recovery and asset value. -
Novel lift systems, AI-driven automation, and real-time engineering models are helping operators extract more value from mature wells. -
This case study from ARC Resources and DarkVision outlines the use of acoustic imaging tools in two active fracturing programs in Canada to monitor well casing deformation. -
This case study from Tomax outlines the use of artificial intelligence to analyze high-fidelity data of the full drilling process. -
The creation of SPE’s Acid Stimulation Technical Section shines a light on the technique that improves injectivity and productivity. JPT talked with the chair of the new section about the importance of the technical area. -
The solvent-based technology involves a modular treatment process that uses a proprietary catalyst designed to safely and sustainably remove hydrogen sulfide (H₂S) from sour gas streams using either produced water or an alkaline water as the treating media.
-
After 4½ years out of service, the massive Wafra oil field is set to resume production soon, and ensuring a smooth restart is no small order. -
Produced water is an inevitable byproduct of oil and gas production. The use of online oil-in-water monitors plays an important role in the management of produced water.
-
Production data from the oldest horizontal wells in the three largest oil plays in the US show that annual decline rates remain relatively high for a long period of time. This challenges assumptions held about production after 5 years and directly affects reserve and ultimate recovery estimates.
-
Oil companies are considering whether shutting in a well for a month or so may mean stronger production later by allowing more time for water to soak into the rock, which gets it out of the way of the oil and gas. But this is not always effective, and additional work is needed.
-
Hess is testing whether it can drive drilling improvement by combining drilling rigs equipped with automated functions and humans determined to find a way to beat the programmed drilling.
-
Rigs drilling faster earn less money per foot because they are contracted by the day. But at least they are still working. Now service companies are developing new rigs with more automated functions, and want increased rates based on the productivity gains achieved.
-
The shale sector is seeking answers to a complex issue involving casing deformations that block access to long sections of a lateral. As opposed to frac hits, this rising problem is considered to be an intrawell phenomena.
-
Heavy production spiked in two Canadian wells heated by an electric cable, but it is hard to find customers there at a time when Canadian oil prices and customers remember cables in the past that died young.
-
The formula for value in a shale play used to be simple, lease acreage in the best quality rock based on Tiers cover large areas. That standard is fading as it has become obvious that the rock is highly variable and the drilling and completion designs are just as important.
-
Merging new knowledge and technological capabilities among the disciplines—and beyond—will be crucial to sustaining the industry for the long term.
