FAULTRISK PROSPECT RISKING

Robust Stochastic Fault Seal and Trap Analysis

Oil and gas exploration is based on understanding uncertainty and deriving risk. Our publications show how we produce simple stochastic solutions for complex problems.

 

FAULT ARCHITECTURE AND QC

A consistent fault interpretation is the foundation of any FaultRisk Analysis.

Trap and regional fault geometries can be reviewed based on either fault polygons or an image of depth structure contour map. A regional fault framework review is conducted to define fault populations and statistics. Appropriate fault geometry can often increase gross rock volumes for fields or prospects.

REGIONAL SEAL IDENTIFICATION AND VALIDATION

Learning from discoveries and dry wells

In many brownfield exploration regions, there is enough information in historic well completion reports to conduct a FaultRisk analysis. Working systematically through a series of fault dependent structures a robust understanding of seals can be derived. In many cases, fluid contacts can be “hind-cast” with better than 15m accuracy. Importantly this methodology is used on dry wells. In this way, charge risk can be assessed.

ROBUST PROSPECT RISKING

Based on regional studies probability and distributions of trapping columns are provided

The fundamentals of exploration are based on describing the chance of finding an uncertain volume of hydrocarbons.


Based on regional studies, probability distributions for column hydrocarbon column height are provided.

Working with a holistic approach trap analysis allows exploration teams to define conservative maximum column heights for prospects.

SIMPLE COSTING MODEL

Excellent results using simple easily found inputs

In many cases, a calibration back analysis can be completed using the data in a public domain well proposal.


These results can be used on a rapid turnaround basis to provide a fixed price analysis for a new prospect.

Regional seal studies can be provided bases on a number of structures with modest contingency.
