Calculate the total pressure drop at an observation well located 1500 feet from a producing well in a virgin reservoir. The single production well was maintained at a constant production rate of 300 STB/D for 10 days; then the rate was increased to a constant rate of 500 STB/D for an additional 25 days. The initial reservoir pressure was 2500 psia. Assume the reservoir was infinite acting during this test. Other reservoir and fluid properties are as follows: (use kH for perm)
