Abstract
Computer graphics were used to analyze dynamic pressure responses from short-term interference tests that were conducted in an attempt to outline the natural and induced fracture systems in a petroleum reservoir. By use of a time-programmable data acquisition system, pressure responses from 40 wells arranged in 16 regular 5-spots were monitored during 74 water injection tests that resulted in over 120,000 individual pressure readings. To aid in the interpretation of the complex field behavior, the data were transferred to computer cards. Software was then developed using cathode ray tubes (crt), drum plotter, and on-line printers to reduce and evaluate the data. Pressure-time plots were generated for each well in a test. From these plots, tests that indicated evidence of existing fracture systems were selected for more detailed analysis. Of the selected tests, sequenced delta pressure contour maps were used to show the dynamic behavior of the field due to the interference test. Graphic three-dimensional perspective views of the changing field pressures were also used in the interpretation of the reservoir behavior. Results of two specific tests are shown.
