This morning SPS moved in and rigged up to do an Acid Frack on the Llama 13-1 well as scheduled. We ended up pumping in 4250 Gals of 20% HCL Acid in four stages with a total of 566 BBls of Slickwater. the entire process went well, pumping at a rate of 20 BBls per minute at an average of 680 psi. The instant shut-in pressure was 280 psi, after 15 minutes it was 80 psi. about as good as you could expect.
D&M ran the tubing back in the hole when the frack job was complete. They will come back in the morning, run in the rods & downhole pump, hook everything up, and turn the well back on. By the first of the week we should be seeing oil/gas if not sooner.
After SPS finished the Viola Acid Frack on the 13-1 well, they rigged down and moved over to the Llama 13-2 well, rigged up and started a 12,000# Sand Frack on the Gilcrease formation. Again the frack treatment went well pumping in a total of 14,700# of sand (SPS brought extra so we used it as the job was going quite smooth) with a total of 379 BBls of water and crosslink Gel to carry the sand in. The average pumping rate was 12 BBLs per minute at 1240 psi. The instant shut-in pressure was 960 psi dropping to 830 psi after 15 minutes, indicating we could have some good down hole pressure that is pushing back.
We have the 13-2 well shut-in to let the frack sand settle over the weekend. Monday we start with a few swab runs and then run all of the tubing, rods, and downhole pump back into the wellbore, hook everything back up, and turn it on.
Next week should be quite interesting.
