Data science and analytics are playing an increasingly important role in all aspects of energy exploration, production, and distribution. Welcome to an interview with Giewee Hammond, senior data scientist at Aramco, who talks to us today about the formative influences in her life, and the current trends and future possibilities in data science as they relate to energy.

Field Trip Description

Analogues, especially ancient outcrop and modern analogues, have played a crucial role in improving the understanding of subsurface reservoir architectural elements. They provide important information on subsurface reservoir geobody size, geometry, and potential connectivity, which all contribute to better reservoir characterization, mainly in highly heterogeneous siliciclastic or carbonate reservoirs that require the integration and detailed analysis of petrophysics, facies, diagenesis, geometry, depositional environments and lateral and vertical variability.

Subsurface reservoir models are limited by available geological data. Outcrop and modern analogs from comparable systems provide additional input to geological models of the subsurface. This field trip will provide valuable insights into the nature of this complexity.

Aims and Objectives

The field trip will comprise a field study of a range of continental clastic modern systems and marine carbonate ancient systems, and related sedimentary facies, each of which possesses attributes that are comparable in part to the subsurface deposits.

Field trip attendees will gain knowledge about key competencies related to field geology such as measuring vertical sections, describing sedimentary structures and textures, describing sedimentary facies, identifying depositional environments, and linking sedimentological observations to subsurface reservoir modeling.

One specific aim of this field trip is to emphasize that integrated reservoir characterization and modeling processes take into account actual depositional trends and the distribution of the sedimentary bodies.

Intended Learning Outcomes

This field trip will provide explanations and discussions of the following aspects:

  1. Basin age, mechanisms of tectonic development, and regional palaeogeographic setting.
  2. An introduction to techniques and criteria for the recognition of continental (fluvial and aeolian systems), shallow marine and carbonate related sedimentary facies in outcrop and modern system and discussions of the application of these techniques to the study of subsurface sedimentology and geological modeling.
  3. Discussions of the 1D, 2D and 3D facies architecture with particular consideration of the geometry and scale of key stratal bodies that have relevance for understanding subsurface hydrocarbon reservoirs.
  4. Discussion of the nature of autocyclic (intrinsic) interactions between competing sedimentary processes and consideration of the implications of these in terms of reservoir quality.
  5. Discussion of the nature of allocyclic (external) controls on sedimentary processes and consideration of the effects of temporal and spatial changes in these controls on the preserved succession (through introduction of sequence stratigraphic concepts).
  6. The significance of accurately determining the preserved geometry of reservoir successions and how to undertake correlations at the interwell scale.
  7. How to predict the 3D distribution of net versus non-net reservoir.
  8. How best to make region-wide predictions in areas for which palaeogeography is poorly constrained.
