the development of a reservoir to extract its oil.

Additional drilling or application of new technology to further extend production and reserves of an existing field.

Focused, integrated effort to extend the economic life, production and reserves of an existing field.

The optimization of oil and gas production or establishing additional reserves from producing properties through development drilling or the application of various technological methods.

A drilling or other project which may target proven or unproven reserves (such as probable or possible reserves), but which generally has a lower risk than that associated with exploration projects.

Various methods of optimizing oil and gas production or establishing additional reserves from producing properties through additional drilling or the application of new technology.

The continuing development of a known producing formation in a previously discovered field. To maximize the ultimate recovery of oil or natural gas from the field by development wells, secondary recovery equipment or other suitable processes and technology.
