ACTIVATION AND SAFETY PROTECTION RUPTURE DISCS FOR DOWNHOLE ACTIVATION OR OVERPRESSURE PROTECTION Continental Disc Corporation Well Activation and Safety Protection Rupture Discs are engineered specifically for downhole applications involving all aspects of producing a well ... exploration, drilling, completion and production. Designed to release pressure to activate downhole tools in the well or to protect downhole components from overpressure failure, our Well Activation and Safety Protection Product Family uses rupture disc technology to achieve high accuracy and reliability. These rupture discs can replace shear pins and other moving devices in most applications and save valuable time and labor on the well-site. Both the WMR and WSP Rupture Discs are offered in two configurations, Type A and Type I, depending on required burst direction: Type A (External Pressure) Well Activation and Safety Protection Rupture Discs can be used to activate downhole equipment/tools from the annulus during drilling or completion operations. Type I (Internal Pressure) Well Activation and Safety Protection Rupture Discs can be used to protect downhole equipment /tools from overpressure within tubing or drill string. Type I rupture discs are also designed to activate downhole equipment/tools from pressure: internal from the tubing or drill string. The Well Activation and Safety Protection Product is offered in two versions: The Machined Reverse Acting design (WMR) is a single-piece design with a rupture disc machined out of Alloy 625. The WMR Rupture Disc provides high pressure solutions up to 20,000 psig. The Welded Tension Acting design (WSP) is a three-piece design with an Alloy 600 rupture disc welded to a 316 SS inlet and outlet. The WSP Rupture Disc provides low pressure solutions down to 1,000 psig. FEATURES Simple pressure activation device Accurate, reliable and consistent rupture disc performance Corrosive resistant materials of construction Quick opening rupture discs have response times in milliseconds Rugged and reliable design Designed to mate with standard/existing port dimensions BENEFITS Quick delivery keeps your operation running smoothly and on-time Simple pressure activation allows operators to activate downhole tools and devices at any depth without relying on pyrotechnics, electronic signals or mechanical systems Easily replaceable parts save drilling and production time by reducing down-time The rupture disc is designed to be self-protecting, minimizing damage by downhole debris PERFO RMANC E

APPLICATION SOLUTIONS WSP Rupture Discs Used for Tool Activation of DrillStem Testing, Replacing Shear Pins WMR Rupture Discs Used for High Viscous Downhole Applications THE ISSUE: An oil and gas service company was designing ¼” HEX. a downhole tool to perforate and hydraulic fracture a well using shear pins. The shear pins did not perform to a high level of accuracy during the development stage of the downhole tool. The service company determined the shear pin performance would not be acceptable ½” for downhole operation. THE ISSUE: An international downhole tool manufacturer was...

Machined Reverse Acting Welded Tension Acting The Machined Reverse Acting design (WMR) provides high pressure solutions up to 20,000 psig. The WMR Rupture Disc membrane is closer to the process media, which reduces the possibility of process build-up. Process buildup may adversely affect the burst pressure. The Welded Tension Acting design (WSP) provides low pressure solutions as low as 1,000 psig. The WSP Rupture Disc is a versatile rupture disc for downhole applications including cementing, completion and hydraulic fracturing applications. The Machined Reverse Acting technology allows the...
