Service Engineer - Liner Hanger Services

1)       Job Summary

The Service Engineer - Liner Hanger Services is responsible for engineering, preparing and supervising the installation of liner hanger and liner-top systems. The role converts the approved casing, liner and cementing design into a verified equipment configuration, engineering package and running programme. The incumbent controls service-base preparation, coordinates rig-site make-up, running, setting, cementing, release and pack-off activities, completes technical documentation and undertakes other duties assigned by the supervisor or Management.

2)       Key Responsibilities

Well Data Review & System Design

• Review the casing and liner programme, hole and casing sizes, liner length and weight, trajectory, pressure, temperature, mud properties, formation constraints and well barriers.
• Select the appropriate hydraulic or mechanical liner hanger, running/setting tool, liner-top packer, tieback or polished-bore receptacle and approved accessories.
• Confirm drift, OD/ID, connection, material, seal, ball/seat, plug, wiper, float-equipment and cementing-head compatibility across the complete liner system.

Engineering Calculations & Job Planning

• Calculate and verify buoyed liner weight, tensile and torsional capacity, burst/collapse, hanger capacity, setting/release pressure, ball-seat shear values, pack-off loads and operating margins.
• Review torque and drag, circulating pressure, surge/swab, equivalent circulating density, running clearance and rotation or reciprocation requirements.
• Prepare the equipment list, setting sheet, drawings, step-by-step running programme, hold points, acceptance criteria and credible contingency actions.

Equipment Preparation & Quality Control

• Verify serial numbers, dimensions, setting-tool spacing, material certificates, inspection and maintenance status before assembly.
• Supervise redress, assembly, torque, drift, function and pressure tests, preservation, packing, spares and load-out.
• Ensure calibrated tools are used and that inspection, assembly, test and traceability records are complete and approved.

Rig-Site Installation & Coordination

• Lead readiness and risk reviews with the client, drilling contractor, cementing company, directional-drilling team and other service providers.
• Direct equipment pick-up and make-up, tally verification, liner running, circulation, hanger setting, running-tool release, liner-top pack-off and retrieval of the running string.
• Monitor hookload, drag, torque, pump pressure, flow rate, returns, ball landing, setting pressure, release indication and other critical parameters.

Cementing Interface & Well Integrity

• Coordinate plug, wiper, float equipment, cementing-head and displacement interfaces with the cementing programme.
• Verify that the running sequence, hanger setting, cementing and pack-off activities remain aligned with the approved barrier philosophy.
• Maintain agreed hold points and acceptance criteria for setting, release, cement placement and liner-top verification.

Troubleshooting & Risk Management

• Diagnose running, circulation, setting, release, pack-off or pressure-test problems using actual job parameters and equipment limits.
• Recommend approved contingency actions and management-of-change steps without exceeding well, rig or product operating limits.
• Apply controls for pressure testing, lifting, rotating equipment, suspended loads, stored energy, dropped objects, red zones and simultaneous operations.

Documentation & Continuous Improvement

• Prepare final tool and liner tallies, pressure charts, setting records, service tickets, installation reports and non-conformity details.
• Conduct post-job reviews and support failure analysis, corrective action, lessons learned and procedure improvements.
• Support technical tenders, client presentations, equipment forecasts, local procedures and personnel competency development.

3)       Authorities

• Stop preparation or installation when equipment, calculations, certification, well conditions, barriers or job parameters are outside the approved basis or create an unsafe condition.
• Recommend liner hanger configuration and contingency actions within product qualification limits, subject to peer review, management of change and client approval.
• Prevent load-out or use until specified inspection, dimensional, assembly, test and documentation hold points are accepted.
• Review and verify calculations, setting sheets, running procedures, tallies, test packs and final installation documentation before submission.

4)       Qualifications & Requirement

• Education: Degree, Master's degree or PhD in Mechanical, Petroleum, Drilling or another relevant Engineering discipline.
• Experience: Minimum five (5) years' directly relevant experience in liner hanger equipment and services, regardless of the accepted Engineering qualification pathway.
• Language: Good command of English and Bahasa Malaysia (written and spoken).
• Technical Knowledge: Strong knowledge of hydraulic and mechanical liner hangers, running/setting tools, liner-top packers, tieback systems, polished-bore receptacles, cementing interfaces, downhole load calculations, torque and drag, hydraulics, equipment QA/QC and well barriers.

5)       Preferred Skills and Competencies

• Ability to select and engineer liner hanger and liner-top systems for defined well conditions.
• Strong calculation capability for loads, tension, torque, burst/collapse, setting/release pressures and shear sequences.
• Working knowledge of torque and drag, hydraulics, surge/swab, ECD, cementing and liner-running practices.
• Competence in equipment spacing, assembly, torque control, drift, function/pressure testing and tallying.
• Precise document control for drawings, setting sheets, procedures, test packs and final reports.
• Strong planning, troubleshooting, risk assessment and management-of-change discipline.
• Effective rig-floor leadership and coordination of client, drilling, cementing and service-company interfaces.
• Valid offshore medical, BOSIET/FOET, H2S, well-control and other client-required certificates, where applicable.
