Abstract

Abstract:

The diagnosis methods for different types of production rate decline are studied. The methods are evaluated under the guidance of J. J. Arps production rate decline theory. Applying the linear relationship between output and time, we can edit programto linear regression, then compare the correlation coefficient and determine the decline type. The application result proves that this approach is simple and feasible.

Key words: source rock, oil and gas migration, undercompaction, abnormally high pressure, downward migration of oil and gas, lithologic reservoirs
