MW 11 and 12 Logs.pdf <br /> Tim, <br /> Thank you for the information,figure and table.As shown in the well design figures, MW-13, MW-14, and MW-15 have <br /> an outside conductor casing annular seal within the first 11 feet. How does AGE plan to remove this outside annular <br /> seal? <br /> Also, in the original work plan,AGE had proposed "...15.25-inch hollow stem augers will initially be utilized (CME-95 <br /> hollow stem drill rig)at wells MW-11 and MW-12 to over-drill to each grout seal depth..." Please clarify the purpose of <br /> originally proposing 15.25-inch hollow stem augers to drill out the grout seal in MW-11 and MW-12.The well design <br /> figures for these two wells only show a maximum diameter of 8 inches(please see the attached file). Do MW-11 and <br /> MW-12 have annular seals that extend beyond the 8-inch diameter? <br /> Thank you, <br /> Gabriel <br /> From: Tim Cuellar [mailto•tcuellar(a advgeoenv.com] <br /> Sent: Friday, March 27, 2015 11:42 AM <br /> To: Gabriel Gonzalez [EH] <br /> Subject: RE: 14749 Thornton Rd., Lodi (3 B's) Permit <br /> Gabriel, <br /> Attached please find a revised as-built construction table summarizing destruction method (i.e. sonic drill) and a site <br /> plan that depicts each well location (wells MW-7 through MW-15). <br /> Hollow stem augers will not be utilized for any portion of these well abandonments. All 3 conductor casings consist of 8- <br /> inch diameter between l'-11' bsg.The inner annular seal was also installed with volclay, so I anticipate the conductor <br /> casing being removed utilizing the hydraulic lift on drill rig. <br /> The sonic drill rig that will be utilized for CMT well abandonments is a TSI 150T Sonic Rig.The driller will be running 8" <br /> casing and 6" core.This abandonment will be done by running the 8"casing to total depth of each well (+1'), followed by <br /> coring-out the well contents with a 6" sonic core barrel all the way to TD ( 8" H90 Sonic Casing with 6" H90 Sonic Core <br /> Barrel). <br /> Please let me know if you need additional information.Thanks-Tim <br /> From: Gabriel Gonzalez [EH] rmailto:aaaonzalez(absicehd.com] <br /> Sent: Tuesday, March 24, 2015 10:25 AM <br /> 1 <br />
