Definition - What does Cumulative Production mean?
Cumulative production refers to the total amount of oil or gas that has been recovered from a reservoir over a specified period of time. It's useful in keeping track of the productivity of a reservoir to determine the investability of an oil field. Energy companies conduct surveys to determine the productivity of an oil field by calculating the cumulative production which is derived by using the formula:
Np = (qi - qt) / D
where Np - Cumulative production
qi - rate of initial production
qt - rate of production at time t
D - decline rate
Trenchlesspedia explains Cumulative Production
Recoverable oil from oil and gas fields is based on the present geological information and the technology available. It has three contributing factors namely cumulative production at given date, proven available resources and unrecovered resources. The demand of oil and gas has increased over the years and so has the need for clean renewable energy.
In the US, the demand for natural gas increases at the rate of four percent annually. Natural gas is in high demand due to its abundant availability, low cost of production, lesser impact on the environment and reduced cost to the end user.
Trenchless technology uses methods such as horizontal directional drilling (HDD), auger boring and microtunneling to install gas pipelines to supply gas all the way from the production site to the consumer using interstate and intrastate pipelines.
