    Structural and Fault Analysis using Petrel -Integrated theory, outcrop and software - Northumberland, NE England

    This course combines theory, outcrop and software training on the methods for the interpretation of fault geometry and fault zone processes and the analysis of fault compartmentalization in exploration and development plays. The group is divided into teams of two to work together in producing a model using Petrel for presentation at the end of the course.

    The Northumberland basin, the onshore extension of the prolific hydrocarbon province of the Southern North Sea, provides a direct hydrocarbon analogue for producing fields at both the seismic and outcrop scale. Well-exposed fault zones along the coast with complex architecture cut the Carboniferous and Permian sands that form offshore reservoirs. Outcrop demonstrations and exercises are designed to characterize the distributions of low permeability fault rock that controls the flow in the subsurface and provide a basis for the theory and methodology to interpret these behaviors in the subsurface using the Petrel Structural and Fault Analysis (SFA) module.

    The outcrop stops are along the North-Eastern coastline of the UK running from Cullercoates Bay (Tynemouth) to Whitley Bay with a local hotel planned for accommodations and lectures.

    The course is designed for exploration and production geologists, geophysicists and engineers working in the subsurface interpretation of faulted prospects in exploration and development plays

    The integration of the outcrop and software models is designed to emphasize the functionality and application of fault interpretation and seal analysis in the SFA module including:

    • Clean-up of horizon interpretation data and structural uncertainty modeling.

    • Structural framework and pillar gridding of faults.

    • Fault–horizon interpretation intersections.

    • Fault-throw profiles and cumulative frequency plots.

    • Fault geometric analysis (including dip, azimuth, throw, heave).

    • Fault juxtaposition analysis.

    • Fault clay content predictions (SGR, ESGR, clay smears).

    • Fault seal prediction (standard published global equations, core calibrated functions).

    • Sealing capacity and column height predictions.

    • Fault permeability and threshold pressure predictors.

    By the end of the course, participants will be confident in:

    • Applying concepts of fault geometry and kinematics to improve subsurface fault interpretation.

    • Identifying and understanding key uncertainties in risking traps with fault seal components.

    • Estimating seal capacities and column heights from capillary seal concepts and clay contents derived from a range of algorithms and incorporating the methodologies in the SFA module in Petrel.

    • Identifying potential trap scenarios and full workflows and methods for deriving seal capacities directly within Petrel.

    • Generating structural models with correct horizon and fault intersections, and checking the quality and uncertainty of the interpretation and model at various stages within the SFA module in Petrel.

    Experience with Petrel is recommended.
