APPLICATION:
Sweeps:
•25 ppb., 25 barrel sweeps.
•180’ intervals.
•Recommendations subject to change pending hole size and expected losses.
This is the third feature
PILL:
•75+ ppb, 100 barrel pill
•Pill should be spotted above suspected loss zone in the open hole.
•Recommendations subject to change pending hole size and current losses.
This is the last feature
Case Study #1
Granite Wash
Two wells were drilled east of Canadian, TX on the Wright Ranch.
Previous average losses in curve and lateral were 2,500 bbls.
1,750 bbl would be considered a success.
Recommendation:
•25 bbl sweeps every 180′
Results:
10 bbls every 45’ or 4 hours, whichever was first.
•Wellbore integrity was improved allowing a mud weight increase to 8.9
ppg to displace a gas kick on the first well.
•Mud loss was 680 bbl and 450 bbl respectively.
Case Study #2
Eagle Ford
Low show test (needed 14.2ppg, got 12.5ppg).
Expected loss zone in intermediate hole section due to fault.
Could they eliminate the intermediate casing string?
Recommendation:
•Run 20-40 ppb, 10-20 bbl sweeps.
Results:
•Minimal mud loss experience due to managing the preventative sweep
program.
•Well was drilled to TD without setting casing string.
Case Study #3
Cline Shale
Seepage reached 20 bbls per hour in the curve (8-3/4” hole, 8K’ MD).
Concern was clogging the RSS tool (previous products had clogged).
Recommendation:
•20 bbl sweeps every stand until losses were mitigated. Then every other
stand.
Results:
•Second sweep eliminated the seepage.
•Sweeps were maintained to TD (15,500’ MD)
•RSS tool was not affected.
Case Study #4
Previous offset well lost 794 bbls to the wellbore.
Recommendation:
•25 bbl sweeps every ±250’ totaling 30 sweeps:
Results:
over cuttings or shakers).
•The previous well lost 794 bbls to hole, and the test well lost 242 bbls.
•Mud cost was $200/bbl.
552 bbls SBM @ $200/bbl = $ 110,400.00
TOP Products Utilized = $ 26,620.50
Test Well Net Savings = $ 83,779.50
Case Study #5
Lusk Field
Expected losses from 3,300’ to 4,600’. TD of hole section was 4,800’.
Common result was total mud loss before section reached TD.
Recommendation:
•25 bbl sweeps every 30’.
Results:
•Maximum mud loss experienced was only 15 bbls per hour.
•Cement was run to surface after setting casing with full returns.
•Hole section was drilled in two days.
Case Study #6
Haynesville Shale
Seepage reached 6 bbls per hour.
ROP was 18’ per hour.
Lateral was to be drilled 5,500’.
All other LCM on rig was used with no success.
Recommendation:
•15 bbl sweeps every 180’.
Results:
•Once sweep was pumped, seepage was completely mitigated.
Case Study #7
Permian – Reeves County
After drilling out the 9 ⅝” shoe @ 9,910’ and getting a 13.5 ppg shoe test, the 8 ½” hole was drilled to 9,963’ where losses began up to 100 bph. Previous average losses in curve and lateral were 2,500 bbls.
Recommendation:
•10 bbl 25 ppb sweeps were recommended every stand while drilling to
TD @ 18,760’.
Results:
•Losses were mitigated and the 8-1/2” holes section was drill with
minimal losses.
•Sweeps were placed when seepage was experienced.
•Once sweeps were pumped, seepage was completely mitigated.
•While drilling the lateral, the mud weight was successfully increased to
13.6 ppg.
•Operator commented that this would not have been achieved had
Tactical Blitz® not been utilized.
