Location & Business Unit Overview

Discovery House, Aberdeen

Position Overview

Provide support to the asset for all Geological aspects of Scott Area, including, but not limited to, development of depositional models, reservoir correlation, static geomodel build, volumetric estimates and well planning. It is the duty of the geologist to integrate G&G data and provide geological support to the appraisal, development or ongoing development of the asset

Job Duties & Responsibilities

Good ideas – a good geologist will not only do the necessary day to day tasks, but will think of the key issues that underpin the field. He/she will continuously question the geological data and look for robust and/or innovative technical solutions

Tasks – the geologist will be expected to perform geological tasks to an agreed standard. There should be no exceptions to this rule. Although time is often limited, any task should be performed to a minimum standard and this should not be compromised. Typical tasks include:

Reservoir evaluations and integration of both regional and asset focussed reservoir data.

Volumetric estimation and distribution of STOIIP. This requires the integration of many forms of geological, geophysical and engineering data employed in both deterministic and probabilistic assessments. The geologist will also provide indicative resource estimates using recovery factors

Provide stratigraphic descriptions through the interpretation of local a regional correlation data (lithostrat, biostrat’, petrology, petrography, logs heavy minerals etc)

Description of the structural geology including structural style definition, stress regime, fracture prediction, fault seal analysis and the potential influence of structure on reservoir presence and quality

Core descriptions. Clear understanding of the implications of detailed core descriptions to the depositional model(s) and an ability to breakdown the facies information from core into a more useable format for model construction

Description of depositional systems and sedimentology relevant to the asset leading to communication of conceptual models and characteristics of the reservoir that influence fluid flow (production/injection) and are required to be captured in the modelling phase. Collation of producing field and outcrop study analogues to support conceptual models

Reservoir Modelling and Characterisation including 3D model construction and visualisation. Work closely with the reservoir engineer in creating grid designs. Create facies and property parameters related to the conceptual depositional models using a variety of techniques and perform appropriate upscaling of properties for reservoir simulation in collaboration with the Reservoir Engineer

Log analysis/Petrophysics. Clear understanding of how log responses relate to geology and basic understanding of log analysis. Use log data as key inputs to depostional and reservoir quality modelling.

Well planning. Work closely with the Geophysicist to prepare well prognosis for drilling and identify any potential geotechnical uncertainties, risks or hazards to the Drilling Engineers. Define with the asset team data requirements from the well including, cuttings, core, mudlogging, fluid samples, logging requirements.

Education & Experience
  • Undergraduate or post-graduate degree in Geology or Geoscience subject or equivalent required.
  • Post graduate Petroleum Geology qualification preferred.
  • Previous oil industry experience
  • Professional designation, e.g. CGeol, CEng, desirable
  • Affiliation to professional body e.g. GeolSoc, AAPG, PESGB desirable
  • Robust knowledge and understanding of the upstream oil and gas business model
  • Broad knowledge of G+G, petrophysics, and production engineering
  • Detailed knowledge and / or experience of the following:
    • Fundamentals of petroleum geology
    • Sedimentary processes in a number of different environments
    • Basic structural geology and structural geology principles
    • Techniques for mapping and predicting reservoir presence and quality
    • Geotechnical Risk and Uncertainty analysis
  • Operational, offshore experience would be desirable. In any case an understanding of the offshore environment is essential.
  • Ability to work within a team in a positive, friendly, non-confrontational manner, but also able to challenge the conventional wisdom in a logical and non-threatening way.
