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.
-
Many of the worst oilfield incidents have been attributable to human factors. Consequently, a corporate well-control manual was refreshed to include human factors in the management of well-control incidents. -
In a plenary session at the Unconventional Resources Technology Conference, executives in charge of unconventional operations for international oil companies talked about how they have slashed their cost per barrel.
-
Tight formations are candidates for hydraulic fracturing as the default. However, the solubility of carbonate by various chemicals provides opportunities to extend the well drainage radius effectively without the intensive equipment, material, and infrastructure demand of hydraulic fracturing.
-
This work is a study of collapse pressure of perforated pipes to evaluate the effect of lateral perforations on the radial resistance of pipes under external pressure.
-
The treatment in a deepwater, frac-packed well with fiber-optic-equipped coiled tubing (CT) and a rotating, hydraulic high-pressure jetting tool achieved successful stimulation of a 500-ft-long frac-packed zone after several previous failures using different techniques.
-
This paper discusses a novel approach to abrasive perforating, including the first-ever use of an acid-soluble abrasive material and ending with CT-jetting-assisted nitrified stimulation.
-
Advanced horizontal drilling, multistage hydraulic fracturing, and other technologies have helped make the Vaca Muerta shale oil and gas resource economically viable.
-
This paper describes the testing of a novel concept based on resistivity measurements to monitor acid-stimulation operations.
-
This study aims to investigate the efficacy and feasibility of cryogenic-fracturing technology in enhancing the permeability of unconventional-reservoir-rock analogs.
-
Significant production gains are being made with hydraulicly fractured wells using diversion to stimulate a higher percentage of the perforations.
