Independent global completions service company Tendeka said it has launched a new technology that increases oil recovery by improving injected water conformance in fractured reservoirs or by ensuring effective placement of matrix stimulation acids.
When installed across a segmented wellbore, FloFuse autonomously chokes back injection into thief zones or large fractures that dominate the outflow profile and ensures effective injection into the rock matrix or fracture structure. This prevents early water breakthrough into production wells, thereby, increasing total oil recovery and reducing water production.
By triggering at a predetermined flowrate, it reduces the outflow area in the completion compartment. Furthermore, the dynamic and reversible operation of the valve makes it suitable for applications where the permeability contrasts change over time, such as in thermally fractured water injection wells and where matrix stimulation is used to improve near wellbore permeability.
Tendeka said FloFuse devices are easy to run in horizontal wells and high rate environments and have a longer life expectancy with less need for maintenance.
Tendeka has installed more than 7,000 passive ICDs and 28,000 Autonomous ICDs globally. In the Middle East, where fractured carbonate reservoirs account for 70 % of global oil reserves, the company has been working with KOC, ADCOand Petroleum Development Oman to provide solutions and support for lower completions projects.
