High-Performance Open Hole Well Completion Systems

Simple, Reliable, Flexible

Tartan’s Multifrac™ Limited-Entry And Enerfrac™ Single-Entry System Can Also Be Run As Open Hole Completions

The same sleeve designs are utilized and run between Tartan’s Isolation Packers to provide the desired stage number and density. Pumping a ball to the Toe Circulation Sub enables pressure activation of the Isolation Packers and subsequent initiation of communication with the annulus via the Hydraulic Initiation Port.

ISOLATION PACKER

The Tartan Isolation Packer is a high performance, hydraulic-set open hole packer, which provides single or multiple high-pressure zonal isolation. The Isolation Packer is an integral component of Tartan’s MultiFrac™ limited-entry and EnerFrac™ single-entry systems for open hole multistage stimulation applications.

HYDRAULIC INITIATION PORT

Tartan’s patented Hydraulic Initiation Port is a hydraulically activated flow port used for the first stage of all MultiFrac™ limited-entry and EnerFrac™ single-entry systems for open hole multistage stimulation applications. The unique configuration includes a redundant BurstPoint™ port feature to ensure full opening for effective stimulation of the first stage.

TOE CIRCULATION SUB

Tartan’s Circulation Sub (CS) is used to control flow between the completion string and annulus in all open hole multistage stimulation applications. By closing off flow with the annulus, the Toe Circulation Sub enables activation of tools in the completion string via hydraulic pressure.

The tool is activated by pumping an appropriate activation ball and is designed such that once activated, the ball is no longer needed to provide the seal.
