CGR calculation and identifying contaminated samples

Description Text

Presentation

The estimation of product yields from natural gas is a fairly straightforward process based on the physical properties of hydrocarbons and a simple  material balance calculation.  A fairly accurate estimate can be obtained from a downhole gas sample; there is no requirement for a costly production test or extensive process modelling.  While the estimation method is commonly used in the industry, there is often confusion about its accuracy, particularly with regard to booking reserves and performing economic evaluations.  This presentation will review the methodology of the calculation and also pitfalls associated with SBM contamination of gas samples collected downhole.
