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 Logging <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 />
