Initial 3 well trial Wired DP w/ Nitrified OBM on 3 wells Observations 1st lateral BHA noticed high stick slip, ended up cutting off N2, tightened up jetting on subsequent BHAs (150 psi) C/O Weatherfords membrane unit to high…
Next 6 wells Wired DP only Observations Get rid of N2 unit and surf equipment // can call out in event of significant loss If losses encountered get aggressive w/ LCM (cedar fiber) Faster Telemetry Total Estimated Additional…
