As production from conventional wells in existing fields has declined, operators are focused on optimizing the output of these aging wells. Production rates typically will taper off over time, leading to an increase in the cost needed to produce the same amount of hydrocarbons. Rather than forcing the operator to choose between costly workovers and deferred production, Weatherford has developed new alternatives using completions technologies that help rejuvenate the wellbore, address declining production rates, and minimize operational costs.
Helping to protect our clients’ investments with reliable life-of-well technologies and solutions
Providing technologies that reduce the need for intervention and reduce overall NPT
Rejuvenating aging wells with the least amount of intervention
Weatherford is the market leader in providing solutions to the challenges of aging reservoirs. Whether the issue is deferred production, safety‑valve failure, or a completely shut-in well, Weatherford has a range of innovative products and services to meet our clients’ needs.
We work with clients to determine whether the problem is best addressed by updating the lift method, remedying liquid loading, restoring safety valve functionality, or managing high sand production. Our portfolio of technologies — including a revolutionary self-mitigating sand screen — combined with our completions expertise, enables operators to get the utmost out of their assets. These solutions can be customized to address the unique challenges of each conventional field.
Technology is at the heart of our approach to meeting clients’ needs. We constantly update and refine our technologies to solve new challenges encountered in the field.
Developed jointly with ExxonMobil Upstream Research Company, this self-mitigating, standalone screen system incorporates a maze design to constrain local sand ingress caused by screen damage. Using a tortuous flow path that moves fluids through two separate screen compartments, the MazeFlo screen filters out sand without interrupting well production. In the event of sand‑control loss in the primary filter, solids pack inside a secondary chamber. This design protects the wellbore from further sand production — without surface intervention.
Our Renaissance systems include a series of complementary technologies that enhance production rates and increase total recoverable reserves in brownfield assets with minimal workover costs.
The IGLS is a method of gas injection via an insert string. Installed using traditional intervention techniques rather than a workover rig, the system is a cost effective way to increase production in an aging well.
