Webinar: Traps & Gross Rock Volume

15 Mar 2017

About This Course
Gross Rock Volume (GRV) constitutes the largest uncertainty for probabilistic volume assessments of undrilled prospects. It is therefore of the greatest importance to understand this uncertainty well and to capture it realistically in probabilistic prospect volume assessments. 

The parameters that contribute to the overall GRV uncertainty include time-depth conversion, reservoir thickness, trap compartmentalization and uncertainty of hydrocarbon (HC) column length. Of these, it is this last factor (column length uncertainty) that generally has by far the largest effect on the total GRV uncertainty range. When discovered HC volumes fall outside the predicted range of prospect volumes, in many cases it is because of errors in the column length prediction: the total uncertainty range tends to be not fully captured, and the mode of uncertainty distribution is too often a “hoped-for” (possible) value instead of a geologically sound most likely estimate.

What will you learn:
This webinar focus will be on how to best make reasonable column length predictions and on how to realistically capture the total uncertainty range. To do this we need to:

  • Understand the geology of the prospect, the trap geometry and the related uncertainties.
  • Understand the geological control on the depth of HC-water contacts, at what depth is the spill point of a trap, and where are potential leak points?
  • Understand the juxtaposition of lithologies on either side of the fault, the geometry of layers on both sides of the faults and the likelihood that the fault may be sealing.

About your expert presenter: Dr. Jan de Jager
Dr. Jan de Jager has a PhD in Geology from the University of Utrecht. He joined Shell in 1979 as an exploration geologist & worked in several locations around the world which includes Gabon, USA, Australia, Argentina, The Netherlands and Malaysia. He took on roles in technical and management positions in the various locations of work. During the last 10 years of his career with Shell, he was responsible for quality assurance of exploration prospects in many parts of the world and for upgrading and replenishing Shell's global exploration portfolio. During this period he also developed extensive expertise in Prospect Risk and Volume Assessments for which he ran successful internal training programs. Following his retirement from Shell in 2010, Jan de Jager took on a position as part time professor at the University of Amsterdam and he is also working as consultant exploration advisor for various E&P companies.
