Tendeka continues flow of new technology launches to boost oil recovery
In response to the challenges of effective water injection in fractured reservoirs, Tendeka has launched a new technology to optimize oil production.
As an addition to their extensive range of advanced inflow control technology, FloFuse can increase 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 pre-determined 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.
Unlike conventional water flood management technologies, FloFuse devices are easy to run in horizontal wells and high-rate environments and have a longer life expectancy with less need for maintenance.
“The benefits of passive injection control devices (ICDs) in injection wells have been well proven but unless the fractures are identified prior to installing the completion device, it has limited ability to effectively distribute outflow,” Annabel Green, Chief Technology Officer with Tendeka, said.
“We have been able to leverage our extensive experience in advanced inflow control technology to solve this very real industry problem. FloFuse has performed extremely well in simulated operations and static well modeling and we are in discussions with several operators on their applications for 2019,” Ms Green said.
Tendeka is the world leader in ICD technology and 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 Kuwait Oil Company (KOC), Abu Dhabi Onshore Operations Company (ADCO), and Petroleum Development Oman (PDO) to provide solutions and support for lower completions projects.
In September this year, Tendeka also unveiled a new suite of applications to safely cut costs, time and minimize environmental risk in unconventional shale plays in the US. The MajiFrac Solution is a portfolio of applications which includes a specially blended thermally stable modified acid system, the company’s field proven MajiFrac Composite Plug, which incorporates a pump down feature to minimize water by-pass, and MajiFrac, a range of high-viscosity friction reducers.
“As a global specialist in advanced completions and production optimization solutions, 2018 has been a momentous year for technology development and deployment,” Brad Baker, CEO with Tendeka, said. “In just 12 months, the launch of a new, demand-led technology, as well as suite of solutions for the unconventional sector, is testament to our team of dedicated and experienced engineers and staff who are committed to creating bespoke solutions to solve the most complex well challenges that our clients face.”
