... production decline analysis methods overcome the main weaknesses of conventional rate versus cumulative production decline curve analysis; namely the often unrealistic assumption of constant flowing pressure, and the fact that early time data may not actually exhibit decline. In practical application...

... rights are reserved. This is a pre-print and subject to correction. Abstract Material Balance calculations for determining oil- or gas- in-place are based on obtaining static reservoir pressures as a function of cumulative production. This requires the wells to be shut-in, in order to determine...

... thickness and quality. To compare gas rates and cumulative production, time zero production plots were constructed. As shown in Figure 6, time is displayed on the x-axis in terms of operating hours elapsed since initial production at time zero. Average cumulative production per well in the group...

... artificial waterflood.4 Cumulative production from the reservoir is 4.638 MMBO, 11.3 BCF and 2526 MBW. This represents 31% of the original oil in place and 40% of the original gas in place. Based on the drive type mechanism and placement of existing wells, potential reserves are in the neighborhood of 1.4...

... Abstract A linear material-balance plot constructed based on "P/Z versus cumulative production" is frequently used to define the Original-Gas-In-Place (OGIP). The defined OGIP is then used to estimate the reserves. However, a linear P/Z plot can only be obtained if the well is producing free...
