files included and any necessary explanations of the data. A separate file containing any edited data used in the analysis can be submitted as an additional file. 10. Tabular summary of the injection rate or rates preceding the falloff test. At a minimum, rate information for 48 hours prior to the falloff or for a time equal to twice the time of the falloff test is recommended. If the rates varied and the rate information is greater than 10 entries, the rate data should be submitted electronically as well as a hard copy of the rates for the report. Including a rate vs time plot is also a good way to illustrate the magnitude and number of rate changes prior to the falloff test. 11. Rate information from any offset wells completed in the same interval. At a minimum,the injection rate data for the 48 hours preceding the falloff test should be included in a tabular and electronic format. Adding a rate vs time plot is also helpful to illustrate the rate changes. 12. Hard copy of the time and pressure data analyzed in the report. 13. Pressure gauge information: (See Appendix, page A-1 for more information on pressure gauges) • List all the gauges utilized to test the well • Depth of each gauge • Manufacturer and type of gauge. Include the full range of the gauge. • Resolution and accuracy of the gauge as a%of full range. • Calibration certificate and manufacturer's recommended frequency of calibration 14. General test information: • Date of the test • Time synchronization: A specific time and date should be synchronized to an equivalent time in each pressure file submitted. Time synchronization should also be provided for the rate(s) of the test well and any offset wells. • Location of the shut-in valve (e.g., note if at the wellhead or number of feet from the wellhead) 15. Reservoir parameters (determination): • Formation fluid viscosity, µf cp (direct measurement or correlation) • Porosity, (� fraction(well log correlation or core data) • Total compressibility, ct psi"' (correlations, core measurement, or well test) • Formation volume factor, rvb/stb (correlations, usually assumed 1 for water) • Initial formation reservoir pressure - See Appendix,page A-1 • Date reservoir pressure was last stabilized (injection history) • Justified interval thickness, h ft- See Appendix, page A-15 16. Waste plume: • Cumulative injection volume into the completed interval • Calculated radial distance to the waste front, rwaste ft • Average historical waste fluid viscosity, if used in the analysis, cp 17. Injection period: • Time of injection period • Type of test fluid • Type of pump used for the test (e.g.,plant or pump truck) 3
