---|---|---|---|---|---|---|
1095398499 | 2014-08-22 | I am onsite to witness the cementing operations of the second intermediate casing string. Savanna 640e ran 1678' of 13.375 casing. Calfrac cemented the casing in place with 1336 sacks of class A cement with .125 pounds per sack celloflake and 1% CaCl. | ||||
1105085235 | 2014-08-08 | I am onsite to witness the cementing operations of the surface casing string. Circulation could not be gained by the drilling rig. The decision was made to spot a 64 barrel balance plug at the base of the casing. 1.25 tubing was ran to a depth of 296' and 220 barrels of cement were circulated in place. The tubing was pulled and the fluid level was found at 160' from surface. I instructed the company to wait eight hours and the run the tubing back in and gain circulation before cementing to surface. | ||||
-1311030388 | 2015-05-11 | My inspection today finds CalFrac is staging equipment to facilitate the upcoming hydraulic stimulation operations. | ||||
1378984440 | 2014-08-18 | I am onsite to witness the casing integrity test. Several attempts were made before a problem with the pressure recording chart drive could be fixed. The casing lost less than ten percent of total pressure. | ||||
1428330853 | 2015-04-06 | My inspection today finds Patterson Drilling Rig 801 is preparing to run 5.5 casing after reaching a total depth of 18,110'. |
