Module summary

This module provides theoretical and practical learning with the module focusing on integrating a suite of sub-surface data into a common data set to allow for the learning and skills achieved in parts A, B and C (see below) to be integrated in the final part D of the module, providing the student with a full understanding of how each component works together. The module is divided into four parts: A) Petrophysics and borehole analysisB) Seismic reflection interpretation and sequence stratigraphyC) Geocellular model construction and evaluation of structural Geology implicationsD) The final component of the module consists of an integrated practical where by a suite of data is provided and students, within a group environment, are expected to integrate these data and make an industry-style report on asset.

Objectives

On completion of this module students should be able to understand the underlying principals behind borehole data, seismic reflection data and fault models. They should be able to take these diverse data and integrate them into a single dataset. This will provide the opportunity to investigate how these different techniques are integrated in a workflow typical in both industry and the final independent research project.

Learning outcomes
In Part A students should be able to understand the fundamentals of petrophysics and its use in the analysis of cores and geophysical well logs for reservoir characterisation and hydrocarbon assessment. They should have acquired skills in the analysis of geophysical well logs for determining lithology, porosity and hydrocarbon saturation.

In Part B students will build upon 2D seismic interpretation skills from semester 1 to develop skills in 3D interpretation. They will continue to develop their understanding of the principles and practice of interpreting seismic reflection data, in both a general geological and structural context and in a detailed sequence-stratigraphic context and will develop an understanding of the principles of rock physics applied to quantitative seismic interpretation. At the end of part B, students should have acquired skills to produce 3D geological models based on the interpretation of 2D seismic lines and 3D seismic cubes, and to correlate and predict sequence stratigraphy across seismic data.

In Part C students should be apply industry-standard 3D modelling/visualisation packages to building structural models and considered relationship between model horizons and faults. They should be able to construct 3D geo-cellular models and considered their application.

In Part D students will integrate the learning outcomes from Parts A-C using a single dataset and produce an industry style report. This will be undertaken as a group exercise to highlight the importance of team work in industry.
