Although operators are reluctant to restimulate the best wells, good wells are often excellent candidates. This operator selected a good well, and designed an aggressive TSO treatment incorporating up to 12 ppa 16/20 CarboLite. Production doubled to more than 3000 bopd and paid out the frac treatment in less than 30 days.
In oilfield operation, stimulation is mostly applied on low rate hydrocarbon producers. It is generally difficult to convince management to treat the higher or best producers in a field due to risk of damaging the wells, reluctance to shut in the well (deferred revenue) and more commonly due to misconception that stimulation is a “cure or medicine” for low rate producers or when production drops suddenly.
In this paper we describe the analysis of data obtained from formation testers, well logs (petrophysical and rock mechanics), well testing, material balance, core and Nodal for a high producer well that was hydraulically fractured. Production from the well doubled after the treatment with pay out time of less than thirty days. The key to success is integration of all data, transforming data into knowledge and using it to make appropriate practical decision. This is the methodology of PowerCOMPLETE™ (P roduction Optimization With Enhanced Reservoir Characterization, Stimulation and Completion) solution process where the three elements to success are effectively combined - People, Technology and Process (PTP).
Transparent relationship between the service provider and operator is required to convince all related parties to implement the project.
