We provide a field-based analysis of the range and variation in deep-water siliciclastic conventional petroleum reservoirs. This presentation explores new themes in petroleum reservoir research and applications, as well as approaches to classic reservoir challenges and how they’re being addressed today. We explain why these technical challenges are relevant to exploration, appraisal and development drilling programs. This analysis questions the turbidite reservoir paradigm established since the 1960s and provides a route to modern solutions:

  1. What is the range & variability in the types of deep-water clastic conventional petroleum reservoirs?
  2. What are the key factors determining sediment distribution patterns in the deep sea?
  3. How can first principles of deep-water sedimentology and stratigraphy be used to a company’s advantage when determining depositional environment, and, in turn, bulk rock volume, net to gross and porosity as part of the original oil in place equation?
  4. What is the role played by sedimentary routing systems in determining the overall quality of deep-water turbidite reservoirs?
  5. How can we as an industry simultaneously and at various scales observe sediment gravity flows and their deposits to inform business decisions?

Course Content

Modern outcrops and subsurface data sets provide a mapping opportunity to characterize deep-water depositional systems from shelf edge to basin plain. This includes observations of the grain- to basin-scale framework and key stratigraphic surfaces that subdivide the basin-fill. Analysis from recent mapping campaigns (2009-2020) from over 20 stratigraphic intervals in the Americas, Europe and Asia-Pacific yields the following insights.

  1. The range and variability in deep-water siliciclastic conventional petroleum reservoirs includes deposits resulting from transport and deposition via fluid turbulence, matrix strength and a combination of those two mechanisms.
  2. Sediment distribution patterns in the deep sea are controlled by several key factors including various aspects of grain size and sediment volume, gradient, accommodation and overall basin type.
  3. Sub-bed-scale, semi-quantitative analysis of sedimentary fabric ratios commonly gleaned from core and image logs reveals critical information on bulk rock volume, net:gross and porosity to help determine stock tank original oil in place (STOOIP).
  4. Sedimentary provenance and source-to-sink routing systems are intimately linked to overall reservoir presence and reservoir quality in fine-grained turbidite reservoirs.
  5. Downslope sediment gravity flow behavior can be used to calibrate and understand the predictive attributes in deep-water reservoir type from canyon head to basin plain.

The results of these mapping campaigns reveal new observations on sediment gravity flows, their processes of transport and sedimentation, and their bearing on oil and gas exploration and development in deep-water depositional systems. This presentation incorporates observations from passive margins including faulted slopes and ponded mini-basins, and active margins including foreland, forearc, back-arc, strike-slip, intracratonic and hybrid basins.
