PTA utilising deconvolution and ConvEx


Project Completed

Technical due diligence & asset evaluation

OPC undertook a Pressure Transient Analysis (PTA) study utilising deconvolution and ConvEx. The PTA connected volumes calculated were comparable with those from modelling and ConvEx was successfully used to help determine reservoir geometry, intra-well connection and reservoir volumes.

Disciplines utilised during project

Pressure Transient Analysis

OPC specialises in Pressure Transient Analysis (PTA), also known as Well test analysis, which involves the interpretation and analysis of Drill Stem Test (DST), Extended Well Test (EWT) and Production/Injection permanent downhole gauge data. With a combination of operational and analysis expertise in well testing, OPC is able to maximise the information gained from your data set to give you a better understanding of your asset and enable you to make better business decisions.

Reservoir Engineering

OPC is one of the leading independent reservoir engineering consultants in the world providing services on a global basis to IOCs, NOCs and independent oil & gas businesses.

Reservoir engineering studies have included phase behaviour and equation of state modelling and production engineering.


Convolution Explorer (ConvEx), is an innovative pressure transient analysis software that can be used with exploration/appraisal well test and with long term surveillance-type data.
