ORIFICE™
Rigid Gel System
Engineered for Exceptional Gel Strength and Versatility
ORIFICE™ boasts precisely engineered polymers and crosslinkers, making it the ideal choice for applications where robust bulk gel strength is paramount. This is particularly beneficial for permeabilities exceeding 1 to 2 darcies or addressing cement bond failures.
One of the remarkable features of ORIFICE™ is its exceptional control over gel time, suitable for a wide range of reservoir applications with bottomhole static temperatures from low to high. Upon crosslinking with our specialized engineered crosslinker, this system creates a formidable barrier in both consolidated materials and sandpacks, achieving remarkable permeability reductions of over 90% in both scenarios.
What sets ORIFICE™ apart is its ultra-low-molecular-weight polymer, enabling it to penetrate even the smallest of pores effectively. This pregel solution can be seamlessly injected into matrices with low permeabilities, ensuring adaptability and performance excellence.
Elevating Reservoir Performance
Our cutting-edge gel technology is the very essence that empowers our watre shutoff solutions with unmatched performance. Precision allows us to exert exact control over gel time, making our products a versatile fit for a wide array of reservoir applications, even in the face of demanding bottomhole static temperatures (BHSTs) of up to 300°F (149°C).
As we dive deeper into the science behind our pregel solution, we unveil a lower-molecular-weight polymer, meticulously handpicked for its extraordinary ability to infiltrate the tiniest pores. This polymer effortlessly integrates into matrices boasting permeabilities of 30 mD or more, showcasing its exceptional adaptability and effectiveness.
Crosslinked Gel Removal
In various applications, it's often advantageous to maintain a residual presence of our ORIFICE™ gel within the wellbore. This ensures comprehensive coverage across all perforations and effectively prevents unwanted crossflow within the wellbore during shutdown periods. When the need arises, removing this residual gel is a straightforward process achieved through mechanical methods. High-pressure water jetting, combined with the circulation of gel particles to the surface using equipment like drill pipes, workover strings, or coiled tubing, effectively clears the wellbore.
Mechanical techniques remain the preferred choice for gel removal due to their reliability and efficiency. However, when mechanical methods prove impractical, we offer a range of chemical wash solutions as effective alternatives.
