A pioneering new tool that will revolutionize the oil and gas industry's approach to inflow performance will be launched later this month at the SPE Formation Damage Conference in Lafayette, Louisiana by diversified energy services company, Senergy.
Developed by the oil and gas division of Senergy, Wellscope™ is a market first because it addresses drilling wells from an entirely new perspective by using computational fluid dynamics (CFD). CFD is a computational technology that enables the study of the dynamics of things that flow.
The new tool has the capability to produce 3D models of prospective wells to estimate the inflow performance of horizontal, deviated and vertical wells under various damage and completion scenarios.
Using up to 10 million cells in each model, Wellscope provides a more accurate prediction of a well's performance. In addition, the cells can be recalculated individually or collectively at the touch of a button to provide ongoing updates of a well's condition.
This offers users insight into how to best evaluate and approach the near wellbore inflow performance and as a result maximize the well's performance. The CFD based technology is set to transform the industry's approach to inflow performance, ultimately increasing productivity and cost-effectiveness for clients.
Led by Senergy's Production Technology and Formation Integrity teams, principal production technologist Maria Jimenez and principal formation damage consultant Michael Byrne, have been instrumental in developing the tool.
Michael Byrne, who is also an SPE distinguished lecturer said, "The complexities involved in predicting well performance prior to drilling have been one of the greatest challenges faced by the industry since its inception. The standard approach has depended on generalised assumptions based on comparisons with similar wells and reservoirs instead of looking more in depth at the well and taking the findings into account.
"The oil and gas industry has been poor at converting data in order to get a more accurate prediction of well performance. This lack of adequate modelling leads to gross generalization of the magnitude, depth and impact of damage caused by inflow challenges and, therefore, on any well inflow prediction.
"Wellscope is designed to provide a much more scientific approach. It evaluates a well prior to drilling and allows exploration from every angle. This supplies a more accurate determination of how a well will perform and, through corroborating evidence, allows decision making to be much more informed and comprehensive.
"For example, assessments of muds can highlight that mud 'X' is better than mud 'Y' because mud 'Y' will lead to a productivity reduction of 1,000bpd, or underbalanced drilling will lead to an increase in productivity of 110% by minimizing formation damage."
