Original Well Plan 103/4 casing 2000 TCEQ Base of Carrizo 4000 5500 97/8 Pilot Hole with Cores to 11,200 TVD Plugback and sidetrack with 97/8 bit Set 75/8 casing 45 inclination Cement surface sands through DV Tool Displace with…
Original Well Plan
Revised Well Plan 103/4 casing TCEQ required depth Displace with 11.0 ppg OBM 97/8 hole to 200 above KOP and log well 75/8 casing only if necessary Slim hole size down to 63/4 Pilot Holes are rare
Revised Well Plan
Directional Plan Curve Kick off open hole whipstock if plug back Build rate 810 degrees/100 63/4 7 blade 3/8 cutter PDC 1.83 degree adjustable bent housing motor 5.4 stage, 5/6 lobe, 1.0 rev/gal, 5 B to B 61/2 near bit stabilizer…
Target Management Adjust KOP from open hole log Use psuedo tangets in curve plan Section expansion and faults Attempt to top Eagleford at 4550 degrees Resume 810 degree/100 build rate Trip for lateral BHA when ROP slows Target…
Directional Plan Lateral 63/4 5 and 6 blade 1/2 cutter PDC 1.83 degree adjustable bent housing motor 3.8 stage, 7/8 lobe, 0.5 & 1.0 rev/gal, 5.5 B/B 63/8 near bit and steerable stabilizer 4 DP to TD well in one run Remember tapered…
Drilling Practices 11.2 ppg at log point, 12.5 ppg TD Set 75/8 at anytime if necessary 250 GPM and 70 RPM while rotating Let the hole talk to us Cleanup cycle when appropriate Cleanup cycle/wiper trip to vertical at TD Circulate…
Future Considerations Pad drilling Longer laterals 6,000 7,000 or more VS Rotary steerable 83/4 hole instead of 63/4 hole 5 casing all the way
