Tendeka offers a wide range of modified acid blends for carbonate matrix acidizing and acid fracturing. Our subsurface engineering team helps E&P companies optimize acidizing treatments by providing acid simulations that help to properly select acid blends, minimize volumes and pumping rates, and at the same time deliver optimized injectivity or production rates. Our team of engineering experts will not only optimize the acid design but provide recommendations on diversion or acid placement based on software modelling. Our team of experts help E&P companies leverage existing data they have on their wells to assess formation damage and reservoir parameters for optimum software simulations.

FloFuse Stim is a unique acidizing solution for disposal or injector wells in carbonate formations that combines a smart modified acid that requires less volume and achieves optimum wormholing at lower injection rates than hydrochloric acid alone. Interventionless injection rate limiting technology that responds to dynamic changes in treatment rates and unexpected variations in fluid displacement ensures proportional distribution of treatment fluid along full length of the wellbore and between laterals.

To achieve the efficient stimulation along the entire wellbore length, the well is segmented into multiple zones with one or more FloFuse valves within each zone.  The valve is mounted into the base pipe or screen section. FloFuse Stim is a biased open valve which enables injection at normal distributed rates but closes once a predetermined trigger rate is reached.  The target rates and trigger rates can be varied by application.

This technology can be applied in wells with long laterals with low matrix permeability such as in unconventional developments with high calcium carbonate content, and natural and hydraulically induced fractures. In addition, this technology has application in saltwater disposal or water injector wells in carbonate formations catering to the unconventional shale markets in the Lower US 48 states, where long laterals are being stimulated in one single treatment. For producer wells, FloDual can be deployed, which differs from FloFuse Stim only by the addition of both inflow control devices and autonomous inflow control devices so oil can be flowed back.
