多级压裂工具更新 保障大位移井作业

As extended-reach wells have gotten longer and more complicated, completions have required more innovative solutions. We’re excited to introduce the latest additions to our growing Completion Tools portfolio. Designed to overcome the challenges of horizontal multistage fracturing projects, our new tools are useful in a variety of scenarios and can be customized to address individual customer needs.

The Defender

The Defender is a cementable multistage frac valve that is actuated by internal pressure. Ideal for acid or proppant stimulations, single-point entry completions or completions with high stage counts, and formations with a high frequency of screenouts or water shutoff concerns, the Defender is usable in both cemented and openhole applications. Additionally, the Defender does not rely on formation pressure for initiation, can be run with hydraulically activated or swellable packers, and can be used in an unlimited number of stages.

Features

• Variable activation pressures
• Activation pressure is based on absolute internal pressure
• Full casing frac port flow area
• Each sleeve can be closed after treatment with a mechanical shifting tool
• May be used as a multistage frac valve, or as a pressure activated toe port
• Small 5.3 in. OD
• Full bore ID

Benefits

• Accurate initiation pressure does not rely on formation pressure
• Compatible with both cemented and open hole applications
• Can be run with hydraulically activated or swellable packers
• Unlimited number of stages

The i-Opener Cycle Open

The i-Opener Cycle Open (CO) toe sleeve is designed for use in horizontal multi-zone completions as the primary initiation point to establish injection into the formation without the need for intervention. Useful for first-stage fracs, toe initiation for plug-and-perf and sleeve systems, and both cemented and openhole horizontal multistage completions, the i-Opener CO ensures casing integrity before fracturing begins, provides greater accuracy for activation pressure, and is debris tolerant during activation.

The i-Opener CO allows the operator to test the casing multiple times at a higher pressure than required to open the sleeve.  Once activated, the high-flow area through the ports allows injection of the fluid to support plug-and-perf operations or stimulation of the first frac stage.

The i-Opener CO Toe Sleeve has redundant burst disks to protect the inner components of the sleeve from debris and cement during installation.  The tool functions on exceeding the absolute pressure rating applied to the rupture disks.  Once disks are ruptured, two casing tests are performed.  Pressure applied the fourth time to the casing shifts the sleeve, opening the injection ports, and providing communication to the reservoir.  Once opened, the sleeve locks open to provide full opening through ports.

Features and benefits

• Large I.D. through the tool
• No inner sleeve between ports once activated
• Allows casing test higher than opening pressure
• Engineered rupture disks versus shear screws
• Redundant flow path to open sleeve
• Compatible with industry standard wiper plugs
• Unrestricted large flow area reduces plugging potential
• Ensures casing integrity before fracturing begins
• Greater accuracy for activation pressure
• Debris tolerant during activation

The i-Opener Time Delay

The i-Opener™ CEM TD (Time Delay) is a remotely actuated toe sleeve that is used to establish one or multiple circulation paths from the completion to the reservoir. The i-Opener (CEM) TD is used as a time and cost saving alternative to conventional toe perforating methods, and in applications requiring multiple pressure cycles and full casing pressure testing. In multi-stage frac applications, the i-Opener TD can be used to hydraulically frac the first stage and/or establish injectivity allowing frac balls or plugs to be pumped to the lower completion. The time delay mechanics in the i-Opener TD can be tailored to fit each application to allow for short or long opening delays in a wide range of pressures and temperatures. This capability allows for an unlimited number of high pressure cycles, in heavy fluids, to be performed without operating the i-Opener. After the required high-pressure operations are completed the i-Opener TD can be opened at lower pressure, even in lighter fluids where required.

The unique features of the i-Opener TD allows for multiple hydraulic pressure events in the well to set liner hangers, and to pressure test the liner and/ or upper completion without risking premature opening of the toe. The i-Opener CEM TD is designed to allow validation testing according to ISO 14998, V0 rating, making it suitable for wells where the lower completion is required to be part of the well barrier

Features and benefits

• Customizable time delay with the ability to have multiple time delay windows

• Decouples casing pressure test from flow initiation operation
• Allows multiple pressure cycles in the well over time without compromising liner integrity
• Can be run as part of a variety of multistage fracturing systems
• A sliding sleeve exposes all flow ports to the formation at once
• Large flow area flow ports for increased pumping efficiency and the ability to perform a toe stage frac
• Can be used as part of a barrier qualified lower completion to improve completion efficiencies
• Saves time and cost versus conventional toe perforating techniques
