This paper describes a matrix-acidizing campaign executed successfully in the Gulf of Cambay on the west coast of India.

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

While increasing coiled-tubing (CT) diameter remains a theoretical option to improve reach, doing so creates logistical challenges.

Seizing on historic margins in domestic prices, North American oil and gas companies are increasing their efforts to use more natural gas and less diesel fuel to power their field operations.

A unique fluid-pulse technology has generated impressive increases in ultimate oil recovery in applications in North and South America and the Middle East.

Enhanced-oil-recovery (EOR) methods have been increasingly positioned into the mainstream of project planning these past years as conventional, highly productive, and large reservoirs have become more difficult to find.

In offshore deepwater and extended-reach wells, placing and removing deep-set barriers is often challenging largely because of the distances and depths involved.

This paper provides an overview of an engineering-design methodology that can be followed for tubular-equipment sizing and selection for use in complex wells.

This paper will demonstrate the benefit of liner-drilling technology used to drill and cement an operator’s 9⅝- and 7-in. liners in place.
