Acidizing/stimulation
The Acid Stimulation Technical Section aims to provide a global home for engineers, scientists, researchers, and practitioners working on acid stimulation in carbonate and sandstone reservoirs.
This paper reviews fracturing-program design, completion technology, real-time data collection, data integration, and lessons learned for the Pikka development on the North Slope of Alaska.
The paper describes a project in which extremely challenging stimulations were performed in a fractured tight carbonate in a complex strike/slip stress faulting regime with high tectonic stresses.

Matrix stimulation encompasses pumping processes used to improve the connection between the wellbore and the reservoir. They are effective in a wide range of lithologies and have been successful in most types of completions: cased and openhole, horizontal and vertical, simple and complex, injectors -
This paper presents an alternative approach to designing and executing matrix-stimulation treatments in multilayered carbonate reservoirs.
-
The elliptical (conical) damage profile associated with horizontal wells is well-known, but review of industry-wide applications by different operators shows no corresponding uniform correlation between the damage profile and actual treatment volumes that have been applied.
-
Novel multizone stimulation technologies have enabled the development of tight resources that previously could not be developed economically and have enabled optimization of production resources distributed over thick gross intervals.
-
As oil companies have moved to more-marginal reservoir targets, application of conventional techniques has often yielded disappointing results, and tighter zones are often abandoned for more-promising target intervals.
-
In the Danish central graben, tight chalk reservoirs have been developed successfully through drilling, completion, and stimulation of long horizontal wells.

The deepwater Gulf of Mexico is a technically and economically challenging production environment. High rates and ultimate recoveries are required per well to offset high development costs.
