SCOPE OF WORK: Wellsite Geologist
Coordination and/or realization of all sub-surface geological tasks, from show and cuttings descriptions through to drawing up the wellsite lithology log, pressure log, geotechnical logs, wellsite composite log quick look interpretation, junior well site geologist supervision, mudlogging supervision, LWD/MWD/WL/Coring supervision (as required) and wellsite geological end of well report as specified by the Operations Geologist.
To be noted, the client is keen to place Junior Geologists at the rig-site for Wellsite and Operational training, the Wellsite Geologist needs to be aware of their role as a duty of care and if required specific on-site training.
- Wellsite Geologist should be medically fit for the relevant work locations (offshore, remote location etc) and hold the relevant medical and required valid certification such as HUET, BOSIET for the duration of the operation.
- Responsible for the implementation of all safety procedures and orders applicable to the wellsite for service company personnel or junior geologists under his/her supervision.
- If required, participates in the definition, requirements, and onboarding of sub-surface service companies' personnel and equipment. Providing auditing and inspection as requested (likely Mudlogging, Coring and Biostratigraphy) and feedback not only on personnel performance but also Physical Condition management of units and associate equipment.
- Coordinates and presides pre-job meetings at the wellsite.
- Attends daily drilling and ad hoc meetings. During these meetings and at anytime during operations he/she points out and discusses with the Operations Geologist and Drilling Supervisor any geoscience information, which can help drilling operation efficiency and safe operations.
- Responsible for the quality of all data acquired at the wellsite during the drilling of wells operated by the Operating Unit with the exception of data falling directly under the responsibility of other entities such as Reservoir engineering (tests) or drilling (deviation) or Petrophysics (tool choice).
- Compare real time well data against pre-drill geological prognosis and communicate to Drilling Supervisor and Operations Geologist.
- Through the interpretation of all available data, participates actively in the identification, evaluation and recording of drilling hazards (losses, gains, shallow gas, underbalanced drilling (including connection and circulation gas monitoring, cavings monitoring and reporting), H2S, Wellbore Instability).
- Quick look log interpretation at the wellsite, either during or at the end of a drilling phase, to optimize operational decisions at the discretion of the Operations Geologist.
- Following the quick-look already carried out at the wellsite, may participate, in the interpretation of all the data acquired on the well, notably those acquired in real time such as lithology, gas, LWD and abnormal pore pressure detection parameters and in liaison with the Stratigraphy team.
- In agreement with the Operations Geologist and Well Engineers, and in liaison with other entities concerned, takes the decision to initiate coring, intermediate logging, to continue or halt drilling at casing points or drilling hazards such as salt rafts, faults, unknown stratigraphy etc.
- Ensures application of wellsite standard procedures and standing orders for data acquisition and safety (in liaison with Drilling Supervisor).
- Monitors and validates the proper transmission of data from the rig to base. This includes but is not exclusive to Real Time Operations Centre, Interact, Petrolink, Sharepoint, Well Vantage, email and reports to the onshore team.
- Ensures the proper communication between the mud logging personnel and the rig personnel, notably regarding mud pit level monitoring and gas levels.
- Is responsible for the co-ordination and delivery of the Daily Geology Report and daily updates to the Composite Log and associated data (i.e. LAS files) from rigsite to office/Operations Geologist.
- Responsible for the witnessing of LWD/MWD and intermediate EWL as required and where specifically requested. This requirement will vary between operations.
- Responsible for the witnessing and supervision of Coring as required and where specifically requested. Will be expected to check amount and quality of core recovered, acquire core chips for analysis in field and ensure safe transportation of core.
- Ensures that geological samples, cores, cuttings and isotubes, isojars and mud samples are recorded, prepared and shipped appropriately.
- All wellsite geologists must provide handover notes to back-to-back Wellsite Geologist and email them to the Operations Geologist.
