​

• Strict application of TotalEnergies Company HSE rules and procedures and pro-activity on this matter by participating actively to the “stop card” system and by reporting all incident or potentially dangerous situation.
• Perform well data quality control and validation at the wellsite.
• Predict and evaluate the geological hazards such as formation pressure, gains, losses, caving, differential sticking, acid gas, swelling clay, shallow gas, etc.
• Detect reservoirs and evaluate the fluid content (quick look interpretation).
• Ensure correct data communication at the well site by reporting in due times any event with potential consequence on the project achievement.
• Supervises all well data acquisition such as mudlogging, LWD, electrical logging, coring, solid and fluid sampling (cuttings, cores, side wall cores, gas, oil, formation water, mud, etc), pressure measurements, VSP, etc in accordance with the well data acquisition program as defined in the WSOR.
• Ensure full well data recovery on rig site and guarantee complete and relevant reporting and well data flow from the rig to the company’s operation representative (Operation Geologist Coordinator on site).
• Supervises contractor performance for all the services associated to geological operations ie mudlogging, MWD-LWD, wireline and pipe conveyed logging. This supervision shall include the check of quality and reliability of equipment, necessary spare parts and consumables and the performance of the crew.
• Realize, periodically or at receipt of a new mudlogging/wireline unit, of technical audits to verify the compliance of contractor equipment and personnel to the contractual terms and conditions.
• Supervises and verify the labeling, packaging and shipment of samples and of all documents and reports issued by contractors.
• Work closely with any other supervisors, notably the drilling and mud supervisors, appointed by company in order to form a cohesive and efficient team.
• Organize and/or actively participate in pre-job meetings before each special operation such as wireline logging, open hole tests, etc…
• Junior mentor/trainee well site geologists and therefore contribute to the development of operations geology skills especially for local new professionals.
• Actively participate to technical reports such as the Final Geological Well Reports or to any report related to the use of a new technology or when uncommon environmental or operational conditions are encountered (REX).

Context and environment

• There is no equivalent project of such an industrial drilling magnitude in a remote and sensitive area within the Company today.
• A Green Field Project, the Tilenga field is to be found in a remote location in UGANDA near lake Albert with particularly sensitive environmental conditions.
• A challenging project: heavy and waxy oils produced from 31 drilling pads, (with some of them located in a national park) and treated in a Production Center of 200,000 bopd oil capacity and 650,000 bld of water treatment capacity. Reservoir pressure maintenance is ensured either by water injection or by polymer water injection depending on the reservoir’s characteristics. The project also includes an extended interconnecting network with temperature preservation.
• Multicultural environment: Contractors are anticipated to be in various parts of the world. Ugandan rules and regulations, administrative requirements and technical authorizations as well as international codes for onshore plant will apply.

Accountabilities

The Senior Wellsite Geologist is responsible for:

• Ensuring on the rig site that all geological operations are carried out in strict compliance with the HSE regulations
• Ensuring on the rig site that the operations are performed in accordance with the well objectives as defined during the WSOR process.
• Contributing actively to the well safety through proper implementation of real time detection techniques of drilling hazards.
• Ensuring an accurate and detailed reporting of all matters related to geological operations on the rig site.
• Ensuring the relevance, reliability and quality of the data collected on the rig site.
