Intelligent completions could improve many of the world’s oil and gas wells, but not all are suited to the technology. There is another option.
Casing deformation has emerged as a major challenge in China’s unconventional oil and gas fields, prompting the development of new solutions to address the issue.
The US supermajor is using one of its lowest-value hydrocarbon products to generate double-digit production increases in its most prolific US asset.
-
The technical contributions highlighted this year focus on matrix stimulation of carbonate and unconventional reservoirs. -
Core-flow tests are usually conducted to test and model stimulation treatments at laboratory scale, to predict the performance of such treatments in carbonate reservoirs.
-
When it comes to fracturing, experts argue about many things, but they agree that fractures do not look like lightning bolts, tree roots, or shattered glass.
-
Al Khalij field offshore Qatar is formed of a highly heterogeneous carbonate reservoir with significant remaining dynamic uncertainties.
-
At the SPE Hydraulic Fracturing Technology Conference, one of the most innovative ideas discussed was a liquid proppant designed to turn into strong spherical balls to keep a fracture open.
-
In this cost-cutting market environment, completion engineers face added pressure to maximize the return on every dollar invested when putting unconventional wells into production.
-
As shale operators look for ways to survive amid the current downturn in oil prices, accelerating the refracturing of older horizontal wells is turning into one of the most attractive options.
-
This paper reviews two newly developed novel completion systems that significantly reduce time spent performing multistage stimulation in environments where cost and consequence of failure are high.
-
This paper describes the design, testing, and execution of a unique deepwater completion system that adapts a known multistage ball-drop system used in onshore unconventional reservoirs.
-
There are more than 100 accumulations in the southern North Sea that are flagged as stranded fields. One of these stranded tight gas fields, the Kew field, has been developed successfully with the use of a subsea well, horizontal drilling, and hydraulic fracturing.
