Complete contractor performance evaluations.
Deploy new procedures across all rigs, such as standard operating procedure changes.
Lead all Well Site Emergency Responses per Oxy’s established Emergency Response Protocol.
Confirm all well shut-ins prior to the required deadline, per the Detail Drilling Program, and record in Openwells.
Confirm that notifications are made regarding starting up shut-in wells at the appropriate time and record in Openwells.
Champion Safety and Operational leadership, ensuring that the welfare of personnel is paramount and the integrity of the well and well construction equipment is not compromised.
Lead and encourage participation from all team members in Oxy’s and the Drilling Contractor’s safety programs.
Ensures pre-tour, JSAs, HSE drills ,and operational drills are conducted efficiently and with purpose.
Perform and complete a walk-around rig and pre-spud inspection with the Rig Manager before accepting the rig for spud, ensuring rig equipment and tools are in safe operational condition.
Write a Detailed Daily Operations Plan / Work Instruction for the Drilling Contractors Rig Manager, Driller, and Drilling Service Providers Lead on the Rig. The Plan / Instruction will be discussed in detail every day with the RM, Driller and all Team Leads to ensure every function/discipline on the well site fully understands the operations plan for the day. The Plan will include, but is not limited to the following:
A detailed summary of next steps in the well construction process.
Expectations covering wellbore hazards and special or additional precautions required.
Conditions and timing for contractor personnel and equipment
Any other business that may impact the safe and efficient execution of the well construction process.
Directly supervise and lead all well control and well kill operations in collaboration with the Oxy Oman Drilling Operations and Engineering team.
Be responsible for the timely ordering, checking, and subsequent returns of equipment, materials, and services necessary for drilling activities under company control.
Ensure that the equipment arriving at the rig site for use in the well construction program is certified, measured, and verified prior to running in the hole.
Witness all pressure tests (BOP, Casing, LOT, FIT, SIT, etc.), and other Company well integrity verification requirements as directed by the DE and DS.
Inspects and approve all new well site locations in consultation with the Contractor’s Rig Manager to ensure timely, safe, and efficient rig moves.
Provides feedback to the DS in a timely manner, allowing for remediation of any anomalies and confirming that the wellhead coordinates are consistent with those in the detailed Drilling Program.
Witness the setting and un-setting of all downhole tools.
Be responsible for all casing tallies run-in hole, and will supervise the measuring of all casings prior to run-in hole.
Ensure the rig and equipment are being operated safely and within the equipment specifications.
Ensure the Rig Contractor’s Rig Manager and Driller keep proper and accurate drilling and BHA tallies, as well as all drilling tubular components, on location.
Calculate all cement jobs, confirm calculations with the cement supervisor on location before the pumping job, and ensure sufficient displacement fluid is on location.
Ensure the mud engineer performs thorough mud checks throughout the day and accurately reflects the properties in the daily drilling report and daily mud report.
Ensure the Directional Drillers are maintaining the desired wellbore trajectory, and the DSM communicates all deviations to the DE and DS in a timely manner to prevent unnecessary high doglegs and costly sidetracks.
Verify all tallies are correct.
Witness all casing and liner strings being run and verify proper fluid displacement.
The DSM will monitor all open-hole tripping and as a minimum, will be on the rig floor to witness the first 10 stands pulled off the bottom and the last 10 stands being run to the bottom. In addition, the DSM will always be present on the rig floor for tight hole conditions and tripping through Build Up Sections (BUS) of the hole.
Ensure the Driller is filling out trip sheets properly.
Witness all BHA’s being made up and confirm each is scribed properly.
Confirm all tool measurements with the Driller, Rig Manager and Directional Driller prior to running in the well.
Confirm all OD’s being run in the well will fit and can be fished safely.
Be involved in planning and lead supervision of any fishing operation, and be present for all critical steps.
Ensure that Standards, SOP’s, Best Practices and Established Oil and Gas Drilling Safe Practices are adopted and followed by all contractors.
Ensure the previous location is cleared of all equipment after the departure of the drilling rig.
Ensure well handover documents are sent to the Production team for signature and returned to the DSM.
The DSM is the overall authority during sim-ops and ensures adequate communication is maintained with all participating functions and disciplines involved in Simultaneous Operations.
Ensure the security of classified information on confidential wells.
During problem or troubleshooting situations, ensure sufficient information is acquired to share with the Muscat - Based Drilling Operations and Engineering Teams, so informed decisions can be made.
Checks and verifies for correctness and signs all job reports and tickets for activities carried out on the well by drilling and Drilling Services Contractors, if there is any doubt, consult with the DS.
Ensures accurate financial estimates and costs are entered into Openwells reports daily.
Train and mentor all company early-career/trainee DSMs and other rig-based company trainees.
The DSM’s role is not limited to 12 hours per day. Both day and night DSMs are on 24/7 call for their 28-day tour and will support each other to ensure safe and efficient operations.
