Well Operations Supervisor, Rig

1. JOB IDENTIFICATION

Job Title: Well Operations Supervisor, Rig

Division / Department: Wells / Well Operations

Location: Port Harcourt

2. ORGANIZATIONAL RELATIONSHIPS

▪ Reports to: Manager, Rig Operations

▪ Direct Reports: 0

3. JOB SUMMARY

To lead the safe, compliant, and efficient day-to-day execution of drilling, completion,

workover, and intervention operations on the assigned rig by ensuring well barrier integrity,

supervising critical operations, coordinating contractors, maintaining high-quality reporting and cost discipline, and driving continuous improvement to achieve well objectives, schedule, and AFE (Authorization for Expenditure) targets.

4. KEY RESPONSIBILITIES AREAS (KRAs)

5. Technical Design & Planning

• Develop 24–72-hour rig execution plans from the approved well program

and brief crews and service leads to ensure alignment on objectives, critical

steps, and contingencies.

• Perform and document verification of well barrier envelopes before critical

operations through testing and logging to ensure well integrity and regulatory

compliance.

• Lead pre-job HAZID/JSA (Hazard Identification/Joint Safety Analysis) and

pre-tour meetings, confirming permits, SIMOPS interfaces, and isolations to

mitigate risks and enable safe execution.

• Validate equipment readiness and compatibility with program and interface

requirements, escalating gaps early to prevent delays and ensure

operational integrity.

• Capture lessons learned and recommended program improvements through

daily end-of-tour notes and after-action reviews to support continuous

learning and performance optimization.

2. Operations monitoring and tracking

• Monitor real-time drilling parameters (SPP- Standpipe Pressure, ECD -

Equivalent Circulating Density, ROP-Rate of Penetration, WOB – Weight on

Bit, torque, returns, gas, pit volumes) and respond proactively to anomalies

to ensure early detection and mitigation of well control or downhole issues.

• Maintain and submit accurate 24-hour reports in WellView, including time

coding, NPT/TLR (Non-Productive Time/Total lost Returns), and consumables, to enable reliable data analysis and informed operational decisions.

• Track key rig performance indicators (e.g., connection times, tripping speed,

flat time, circulation efficiency) and apply short interval control to identify

inefficiencies and drive continuous performance improvement.

• Coordinate daily logistics with the shore base and maintain a 7-day

lookahead for materials, verifying QA/QC (Quality Assurance/Quality Control)

of tubulars and tools to ensure timely delivery and operational readiness.

• Conduct thorough shift handovers with clear updates on status, risks,

barriers, and the forward plan to ensure continuity, accountability, and safe

execution between shifts.

3. Risk Management & Compliance

• Enforce HSE standards and critical controls (PTW- Permit To Work, DROPS -

Dropped Objects Prevention Scheme, lifting, electrical, confined space) by

applying stop-work authority and field-level verification to prevent incidents

and maintain a safe work environment.

• Maintain well control readiness by conducting planned drills, updating kill

sheets, and verifying BOP (Blowout Preventer) function tests and

accumulator pressure to ensure rapid response capability in case of an

influx or kick.

• Ensure compliance with regulatory (NUPRC - Nigerian Upstream Petroleum

Regulatory Commission, API/ISO - American Petroleum Institute/ International

Organization for Standardization) and company standards by maintaining

auditable documentation and closing out audit and inspection findings

promptly to uphold license-to-operate and operational integrity.

• Lead incident and near-miss reporting using ICAM (Incident Cause Analysis

Method) or TapRooT(Root Cause Analysis) investigations, implementing and

verifying corrective/preventive actions to eliminate root causes and prevent

recurrence.

• Manage SIMOPS (Simultaneous Operations) by coordinating isolations,

communication protocols, and execution plans across production,

construction, and intervention activities to prevent cross-functional hazards

and operational conflicts.

4. Budgeting, Cost & Reporting

• Control daily spread costs by reducing invisible lost time, optimizing task

sequencing, and performing quality checks to avoid rework and maximize

operational efficiency.

• Validate third-party service tickets, rental days, and call-outs against actual

usage, endorsing only accurate records to ensure cost accountability and

prevent billing discrepancies.

• Forecast daily costs and material consumption, flagging AFE variances early

with root causes and mitigation plans to support proactive budget

management.

• Maintain accurate tallies of equipment, tubulars, chemicals, cement, and

waste, and reconcile inventories at job closeout to ensure material

accountability and cost control.

• Submit daily cost snapshots and weekly summaries with analysis of

performance drivers and cost-saving opportunities to support transparent

financial reporting and informed decision-making.

5. Team Leadership and Management

• Coach and evaluate supervisors, drill crew, and service leads on safety,

procedural compliance, and technical skills by using a competency matrix

and structured training plans (e.g., IWCF - International Well Control Forum,

BOSIET - Basic Offshore Safety Induction and Emergency Training, H2S –

Safety Controls) to build capability and ensure readiness.

• Set clear expectations and assign responsibilities before critical tasks,

verifying understanding and directly supervising execution to ensure

procedural discipline and safe, effective operations.

• Foster a culture of open communication and mutual respect through effective

toolbox talks, positive reinforcement, and timely correction of at-risk

behaviors to strengthen team cohesion and safety ownership.

• Coordinate on-site contractor performance reviews and verify certification,

maintenance, and calibration of critical equipment to ensure service quality

and regulatory compliance.

• Lead post-job debriefs and contribute to end-of-well reports by capturing

lessons learned and improvement opportunities to drive performance and

knowledge transfer across teams.

5. QUALIFICATIONS & EXPERIENCE REQUIREMENTS

• Minimum Qualification:

[Bachelor’s degree in Engineering or related discipline; equivalent experience may be

considered]

• Required Professional Certifications / Accreditations / Registrations:

[IWCF Well Control – Supervisor Level (current); BOSIET/HUET - Helicopter Underwater

Escape Training; H2S; Lifting Appointed Person (preferred); SPE – Society of Petroleum

Engineers/NSE - Nigerian Society of Engineers /COREN – Council for the Regulation of

Engineering in Nigeria membership advantageous]

• Minimum Years of Experience and Relevant Areas:

[8–12 years in drilling/completions/workover operations with ≥3–5 years in wellsite

supervisory roles; demonstrated experience with BOP/PCE (Pressure Control

equipment), completions installation, wireline/CT – Coil Tubing, and SIMOPS]
