6. Trip out of the hole. <br />• If tight spots are encountered, ream through them. <br />• If there is excessive reaming, then perform a clean-out trip down to bottom (short trip). <br />• Circulate and condition hole again. <br />Open Hole Geophysical Logging <br />1. Contact logging company to mobilize to location prior to reaching 1,749' (TD). <br />2. Run open hole geophysical logs from 1737' (TD) to surface. <br />3. Rig up logging company equipment for 6.5" diameter open hole logs. <br />4. Run Gamma/ Density/ Multi -Arm Caliper and Deviation tools from 1,749' (TD). Run any <br />additional logs as determined by Daub. <br />5. Rig down logging company and logging equipment. <br />6. Have logging company provide log with completed header information. <br />Appendix C — Subsidence Monitor Well Completion with Rotary Rig: <br />Casing Installation and Cementing <br />1. Install 4.5" OD x 4.0" ID 11.6# J-55 LT&C (or HWT FJ) steel casing to 1,734'. (Depth TBD <br />based on samples and geophysical logs.) <br />• Install baffle plate / float valve at least 20 feet from the bottom of the casing. <br />• Tack weld bottom three joints or use Baker Lock equivalent cold weld epoxy. <br />• Set -10 centralizers evenly across casing length. <br />2. Cement casing with Halliburton (use 50-75% excess cement, verified by G/D/C log) <br />• Record returns to surface in addition to cementing parameters. <br />• Wait for cement to cure for at least 12 hours. <br />•Take sample of cement to help determine set-up time. <br />3. If cement falls back, prior to re-entering hole then top off annular space. <br />4. Run in hole with 4.0" rotary bit to clean out hole and drill out cement plug to the bottom of the <br />casing at 1729'. <br />5. POOH and strap drill string. <br />Cased Hole Loaain <br />1. Contact logging company to run cased hole logs from surface to 1729' (TD). <br />2. Rig up logging company equipment for cased hole logs. <br />3. Log 4.5" OD cased hole with wireline to TD. <br />• Run Gamma/ Casing Collar Locator (CCL) and Cement Bond Logs (CBL) as determined <br />by Daub; pull all logs from TD (1729'). <br />4. Rig down logging company and logging equipment. <br />5. Have logging company provide log with completed header information. <br />Daub & Associates, Inc. Page 10 of 12 Printed: 4/5/2016 <br />
