ConvEx PTA software has powerful benefits

ConvEx, the innovative pressure transient analysis software launched this Spring by OPC, has received very positive reviews from the global well testing community.   The consensus is that the ConvEx approach provides clear benefits across the entire well range and is particularly powerful when applied to unconventional wells.

In March, Piers Johnson presented to the annual SPE Well testing workshop in Dubai and in April, Riley Smith presented to at the AlMansoori Technology Day in Abu Dhabi.  Both presentations were very well received by the knowledgeable audiences.


Piers said “I was delighted to have been invited to present at the workshop and to have the opportunity to share the benefits of ConvEx. I am particularly excited by this new solution as it can significantly increase the accuracy of the reservoir description, and therefore production forecasting in unconventional reservoirs and can deliver results far quicker than traditional models.”

Riley said “I presented a very brief overview of ConvEx at the AlMansoori Technology day and was pleased to see it generated a lot of interest, including from Mr. Yasser Saeed Al-Mazrouei, the CEO of ADMA/ZADCO. ”

ConvEx has been developed by Michael Levitan, OPC lead PTA consultant, and was first presented to the Well Testing Network in Houston (involving well testing experts from leading companies including BP, Expro, ExxonMobil, Halliburton, Shell and Schlumberger).  The feedback was incredibly positive (see below)

“Whilst this technique appeared to provide clear benefits across the entire well range, its application to unconventional wells may prove particularly powerful.”

ConvexgroupConvEx (short for Convolution Explorer), significantly improves the accuracy of well surveillance analysis and forecasting production, particularly in unconventional reservoirs. ConvEx allows the user to derive a unit rate drawdown response function interactively with the well bottom hole pressure data and surface flow rate measurements which can then be used for future production forecasts.  This is particularly useful in unconventional reservoirs where there are no or few build ups just producing data.

Piersweb“We have received significant interest in ConvEx, particularly from clients with unconventional wells.  I would encourage anyone interested in the topic to contact me quickly as we are already scheduling projects to the end of 2017.”
