Different fields experience different challenges. Some are constrained by gas-handling capacity, others by water- or liquid-handling capacity. Long horizontal wells can suffer from an inactive toe section due incomplete cleanup. For some wells in homogeneous reservoirs, oil production cannot be increased because of the heel-toe effect and associated gas coning. Wells in heterogenous reservoirs may experience excessive water production from high-permeability streaks, which can negatively affect lift performance.
This variety of challenges illustrates the need for a robust inflow control technology that can easily be configured to meet individual clients' field-specific requirements. If you think an investment in this technology could potentially provide benefit to your existing our future field, we are happy to discuss opportunities with you, also for retrofit solutions.
In spring 2018, the DAR technology was prototype tested with reservoir oil at reservoir conditons in Equinor's state-of-the-art HPHT multiphase test facility for AICDs in Norway. All the test results were exceptionally good, but the tests were limited to the performance of the water control module and gas control module. Additional testing at assembly level will be performed during fall/winter 2018.
The potential benefits gained by the DAR products depend on the type of field and fluids, and on the selection of fluid control modules to be used in the ICS
Combine high oil production with an insurance against early breakthrough of water and/or gas
Reduce negative consequences of geological uncertainty associated with long horizontal wells
Reduce fluid-handling needs and reassess producer/injector well count for new field developments
Reduce carbon footprint caused by GHG emissions associated with reinjection of unwanted fluids
