EPA Step Test Process <br />Final Design Concept <br />Pilot Project Drilling and Completion Plan <br />March 14, 2011 <br />a. Once hole has reached Total Depth (T.D.) Circulate and Condition Hole for (1) hour using drilling <br />fluid <br />b. Trip out of Hole lay down directional drilling BHA <br />c. Pick -up pressure recording device and 7 5/8" 26.4 # cased hole packer <br />i. pressure recording device. attached and ran under packer assembly <br />d. Trip In Hole (T.I.H.) with test assembly <br />e. At –1900' ( + -50' above casing shoe) circ thru assembly <br />f. Set casing packer (rotate to the right while lowering pipe) <br />g. Monitor annuls for any drop in fluid level <br />h. Tie -in BOP testing unit (with chart type recording device) to standpipe /drill string on rig <br />i. Using testing unit — pressure up on drill string in (25) psi increments holding pressure for 15 minutes at <br />each increment to calculated (B.H.P.). <br />i. EPA pressure requirement for test of (130) psi above water hydrostatic pressure or <br />8.33 ppg (water) X 0.052 X Depth (2400')= -4170 psi Bottom Hole Pressure (B.H.P.) <br />ii. Actual test pressures during test will be determined by current mud weight of fluid used in <br />testing procedure, it is anticipated that fluid weight used will be 8.6- 9.0 ppg. <br />NOTE: Calculation for added surface pressure requirement for meeting test pressure stipulations is <br />dependent upon fluid weight in drill string and calculated prior to test. <br />Once final /calculated test pressure has been reached and monitored for (60) minutes, bleed drill string <br />pressure off, release packer and trip out of the hole lay down pressure recording device. <br />Download pressure recording device information from tool, correlate with graph on BOP testing unit <br />and prepare testing summary document for submission to agency. <br />Alternative Testing Procedure (Using Freshwater) <br />1. Pick -up pressure recording device and packer assembly and TIH to + -1900' <br />2. Circulate calculated volume of drill pipe with clear water <br />3. Set Packer, monitor annulus for any drop in fluid level <br />4. Using BOP testing unit, pressure up in (25) psi increments holding pressure for 15 minutes at each <br />increment (monitor annulus for any evidence of packer leaking) to EPA required final test pressure <br />of 130 psi. <br />5. Once final/calculated test pressure has been reached monitor pressure for (60) minutes, <br />NOTE: If annulus flow indicates packer leaking during test, bleed off pressure, unset packer, move <br />pipe 5 -10', start procedure from beginning. <br />6. At conclusion of test release pressure - release packer -Trip out of hole -lay down assembly — <br />download recording device information - prepare summary of test using data from recorder and <br />BOP testing unit graph and prepare testing summary document for submission to agency.. <br />1 <br />
