Drilling and completions.

Primary Purpose Of Job

The primary purpose of this job is to oversee the engineering processes and operations related to the integrity of surface wellhead equipment, including but not limited to: Wellhead services, Wellhead Integrity investigations, rectification of wellhead anomalies, wellhead design & tender preparation, wellhead audit, wellhead testing and acceptance, wellhead installations & removal, modification of wellhead, and wellhead surveillance for drilling and completions for both QatarEnergy onshore and offshore fields. 1. Participate and recommend Christ-mass tree and wellhead design to accommodate well integrity surface and downhole barriers requirements. Review all existing installed Christmass trees and wellheads to ensure/confirm compliance with well integrity barriers requirements. 2. Prepare and maintain a data base and... identify all wellheads, Christ-mass trees, valves, and associated seals which required investigations, repair and or replacement, based on close monitoring, follow-up, analysis and statistics, coordinate with well integrity onshore and well integrity offshore teams for the required planning, prepare program and guidelines. 3. Follow up wellhead integrity testing and offer any necessary technical assistance. QA/QC wellhead testing reports, and make sure they are signed off and uploaded in the WIMS. During drilling and workovers, monitor wellhead installation activities and draw attention to any irregularities. 4. Analyse the wellhead integrity testing results in light of the actual discoveries and the methods used for the investigations, and whenever necessary, make recommendations for the best corrective action. Using the well failure model as a basis, determine the failure code and repair procedure, and assist the well integrity onshore and offshore delivering a related integrity analysis report. 5. Lead wellhead and surveillance operations, including wellhead assembly, maintenance integrity testing, removal, and repair, as needed, especially for important wells, while ensuring strict adherence to QatarEnergy Drilling Reference Manuals (DRM) and associated industry standards, worker safety, and work efficiency. Capable to review the work / activities of the wellhead supervisors and field technicians and make recommendations to improve their work practices. 6.
