`
`Gamer "16" No. 1H
`Completion Procedure
`Sheffield, SE (Devonian) Field
`Terrell County, Texas
`October 15, 2001
`
`Executive Summarr
`
`The Gamer 16 No. has been drilled to a total MD ofl1,563' (2,627' ofhorizontal
`lateral). The horizontal lateral will be acid fraced in 5 stages. Open hole packers will
`provide zone isolation. The well will be acid fraced using ZCA acid with 40 Quality
`C02. The workstring and packers will be pulled after the job. 2-3/8" production tubing
`will be installed at the bottom of the curve, which is the low point in the lateral.
`
`Procedure:
`1. Run Packers Plus open hole packers and FracPort tools on 3-1/2" tubing.
`2. Prior to setting the packers, run GR-CCL on wire line to get top packer on depth.
`To allow the upper Devonian chert zone to be completed in the future, the top packer
`will be set below the zone of interest.
`3. Acid frac the Devonian horizontal lateral in 5 separate stages.
`Each stage will be 18,000 gals of 17% ZCA and 7200 gals of 17% slick acid.
`The total job size is 90,000 gals 17% ZCA acid and 5f,OOO gals 17% slick acid.
`Frac down 3-1/2" tubing at 35 BPM at ±7500 psi.
`3 isotope RA tag will be used.
`4. Flow back well to pit and/or test tank for several days.
`5. TOH with 3-1/2" tubing and packers.
`6. Run Afterfrac log on 3-1/2" tubing, then lay down 3-112" tubing.
`7. Run 2-3/8" production tubing to the bottom ofthe lateral.
`8. Return well to production.

`
`I. a) MIRU pulling unit.
`b) TIH with Packers Plus RockSeal openhole packers and FracPort tools on 3-1/2"
`9.3# L80 Srd EUE tubing. See attachmeflt for Depths for packers and FracPort
`tools.
`c) With packers on depth using tubing tally,
`1) RU wireline truck. Run GR-CCL to get the top packer on depth with
`the open hole logs, to ensure that the upper Devonian can be completed
`in the future.
`d) Set all 5 packers (hydraulic set packers). Each to set at a different pressure.
`e) TOH with tubing and setting tool.
`f) TIH with latch seal assembly. Latch into packer.
`g) Land tubing with extended neck hanger, with 40,000 lbs compression on top
`packer.
`h) ND BOP. NU 7-1/16" 10k frac valve. Test frac valve and tubing head to
`10,000 psi.
`Use BPV in mandrel hanger to provide isolation and to test surface equipment.
`i) Load 7" x 9-5/8" annulus.
`j) Test the 3-112" x 7" annulus to 4,000 psi.
`k) Rig up flowback company on frac valve. Install dual choke manifold to flow
`back through. Install ball catcher. Stake down all lines.
`
`2.
`
`a) Rig up Halliburton frac equipment to frac down 3-112" tubing.
`I bank of equipment for liquid.
`I bank of equipment for C02. Set anchbts for high pressure C02 lines.
`b) Rig up RA tagging company. Hook RA lines up to 4 PurrtP trucks.
`c) Test all surface lines to 10,000 psi.
`Install pop-offvalve on 3-112 x 7" annulus. Set and test to 4,000 psi on location.
`d)
`
`3. Acid frac the Devonian horizontal lateral down 3-112" tubing with a total of
`90,000 gals 17% ZCA acid and 5#,000 gals 17% HCL, all foamed with C02.
`
`The lateral will be treated in 5 stages.
`The job will be tagged with 3 isotope RA material.
`The acid in each stage will be tagged with a different material. (A,B,C,A,B)
