I’ve included information for our proposed sidetrack and attached a wellbore diagram. Thank you for taking our call in the middle of the night and providing verbal approval. Please let me know if there is any other information you need. Well name and API #: • TULIP WEST 30-1HZ • 05-123-52895 Explanation for need to sidetrack • While drilling ahead in lateral, the BHA crossed a fault from the Niobrara A formation into the Sharon Springs. Hole conditions became increasingly adverse presenting elevated rotating torque, inconsistent differential pressure and unusually high cuttings load on the shakers. Due to the lack of wellbore stability in the Sharon Springs, we will pull back and sidetrack a new wellbore and remain in the Niobrara A formation. Total measured depth reached in the wellbore being plugged back • 14,744’ MD Casing set – size(s) and measured depth(s) • 8.625” surface casing set at 1,885’ MD Description of fish in the hole (if any) – including top and bottom measured depths • No fish left in hole. Description of proposed plugs: setting measured depths, heights, and cement volumes • Open hole sidetrack – no plugs are planned to be set Type of cement to be used for all plugs, including slurry weight (ppg) and yield (cf/sk) • Open hole sidetrack – no plugs are planned to be set Measured depth of proposed sidetrack kick-off point • 12,402’ MD Proposed objective formation(s) for sidetrack hole – new or same as the wellbore being abandoned • Same as original, permitted wellbore – Niobrara A BHL target for sidetrack hole – new or same as the wellbore being abandoned • Same as original, permitted wellbore 404146088 404146088 FORM 2 SUBMITTED 404146088.pdf 404146088 404146111 WELLBORE DIAGRAM Tulip West 30-1HZ Sidetrack wellbore sketch.pdf 29420 404146088 404146112 CORRESPONDENCE Tulip West 30-1HZ_EMAIL APPROVAL.pdf 163125 404146088 404146113 DRILLING PLAN Tulip West 30-1HZ_ST01 Plan #6.pdf 472071 404146088 404146115 DIRECTIONAL DATA Tulip West 30-1HZ_ST01 Plan #6_Permit Rev-2_Survey Template.xlsm 44852 404146088 1ST 7 7 8 5 1 2 17 21661 2464 21661 1000 0 PLANNED HCP110 false false false 404146088 CONDUCTOR 26 16 36.94 80 64 80 0 0 PLANNED ASTM A false false false 404146088 SURF 12 1 4 8 5 8 28 1527 590 1527 0 0 PLANNED L80 false false false 404146088 NIOBRARA NBRR 407-3673 2880 T4N-R67W: SEC 19: W/2; SEC 29: ALL; Section 30: ALL; T4N-R68W: SEC 29: ALL; SEC 30: ALL Thread was being aborted.
