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.

With well testing an infrequent and expensive activity, OPCs specialisation ensures an in-depth and thorough analysis which adds value to your operations. We frequently work with noisy and incomplete data sets and we specialise in the interpretation of complicated well data. In additional to more conventional analysis, OPC also has extensive experience of advanced PTA interpretation such as deconvolution, multi-layer reservoirs and double porosity systems.

OPC has access to industry standard software technology including PIE and Saphir and in 2017 we have introduced Convolution Explorer (ConvEx), an innovative pressure transient analysis software that can be used with exploration/appraisal well test and with long term surveillance-type data.
