StackFRAC Slimhole System

Restimulation & Well Recovery

The Packers Plus StackFRAC® HD Slimhole system is specially designed with a smaller liner outside diameter (OD), enabling operators to re-enter vertical or horizontal wells. This system provides a cost-effective solution for restimulation and well recovery applications.

The Slimhole system was developed with the same features and efficiencies as the Packers Plus StackFRAC HD multi-stage completion system. This innovative system allows for exact placement of stimulation treatments in one continuous pumping operation, saving operators time and money.

The StackFRAC Slimhole system offers many features and benefits

Built on StackFRAC HD technology

Continuous rigless pumping operation reduces completion time and cost

Custom stimulation for each stage of a previously completed wellbore

Immediate flowback after stimulation

The StackFRAC Slimhole system can be used in many applications

Restimulation of existing vertical or horizontal wells completed with cemented liner or open hole multi-stage systems (OHMS) to improve recovery from damaged or depleted zones

FracPORT™ sleeves can be aligned with existing ports to establish communication with the reservoir

Recovery of wells where a loss of integrity has hindered the ability to stimulate

FracPORT sleeves can be aligned with new or existing perforations to establish communication with the reservoir

Field-proven RockSEAL® packers isolate liner breaches enabling stimulation of the well

Stimulation of open hole laterals drilled off of existing verticals to exploit new or depleted zones and increase productivity

Saves on well construction costs associated with drilling and casing a new wellbore

Eliminates the need to drill additional wells to exploit a reservoir

Easily installed through high degree build sections

See what the StackFRAC Slimhole system is made of

FracPORT H2 Sleeve

The FracPORT H2 sleeve is a ball-actuated, hydraulically activated injection/production port. This sleeve is run between two RockSEAL H2 packers to allow specific zones of the wellbore to be isolated and selectively stimulated. By providing a flow area greater than the liner, the FracPORT H2 sleeve provides unrestricted flow for stimulation treatments. The FracPORT H2 sleeve is also available in a Drillable Closeable (DC) version that can be closed or re-opened for future operations. This allows for effective water or gas shutoff, flow control, re-fracturing and production testing.

RockSEAL H2 Packer

The RockSEAL H2 packer is a hydraulically set, mechanical packer. The dual-element design, along with premium seal technology, ensures reliable high-pressure zonal isolation during stimulation and throughout the life of the well. The RockSEAL H2 packer offers ease of installation through its short length, minimum outside diameter and anti-preset features. Hydraulic activation allows for precise control over the setting operation, resulting in time and cost efficiencies.

See how the StackFRAC Slimhole system works

01

The Slimhole system is run into the well, aligning the FracPORT sleeves with the perforations.

02

A ball is pumped from surface to the Pump Out Plug, closing off the system and allowing pressure to build.

03

This pressure sets the system by hydraulically activating the packer and anchor tools. This anchors the system in the casing and creates individually isolated stages.

04

Once the system is set, pressuring up further opens the Pump Out Plug and enables the section below to be re-stimulated, if desired.

05

The next largest ball is pumped from surface and lands in the FracPORT sleeve. Hydraulic pressure is increased, causing the sleeve to open and the reservoir is stimulated through the perforations. This process is repeated in a single, continuous pumping operation. The well can be immediately flowed back and production brought on line.

 Our commitment to quality
