Fracturing and Completion Services
More choices. More reservoir contact.
Contact fracturing and completion services maximize reservoir contact by offering the most efficient and effective reservoir stimulation service for each well. This portfolio of services offers a wide variety of proven reservoir stimulation technologies; each choice can be enhanced with real-time measurement options.
Conventional
Wells completed through the conventional Contact category require separate trips into the well to fracture stimulate and isolate each stage. Conventional solutions can be divided into two techniques: cased hole and openhole completions.
Cased hole completions
Various methods can be used to access the reservoir, including wireline perforating, abrasive jetting, or shifting a sliding sleeve with the workstring. Fracture stimulation of each stage is performed by pumping down the casing or reservoir string. When multiple intervals are open in one stage, diversion can be attempted through various methods including limited entry (perforation friction pressure), ball sealers, or chemical diversion. The stage is then isolated using various techniques including setting composite bridge plugs, setting sand plugs, or natural isolation (induced stress diversion). This entire process is then repeated for remaining stages. A separate trip into the well is required for the next stage.
Openhole completions
In unconsolidated formations, a completion string may be deployed to ensure wellbore integrity. Typical completion strings include slotted liners or preperforated liners. The entire well may be fracture stimulated by pumping down the casing or reservoir string. Diversion can be attempted through various methods including limited entry (perforation friction pressure), ball sealers, or traditional chemical diversion.Intervention
Wells completed through the intervention Contact category fracture stimulate and isolate multiple stages per intervention. The following services are used.
Abrasive Perforating & Fracturing
AbrasiFRAC abrasive perforating and reservoir services cut perforations, fracture stimulate, and isolate each interval separately-all in a single field operation.
Fracturing through Coiled Tubing
Fracturing through stimulation of preperforated intervals through CT or work string involves a straddle tool to isolate each interval during stimulation treatment. This technique is used both for new completions and to access bypassed intervals.
Wireline-enabled Perforating & Fracturing
PerfFRAC technique involves high-rate fracture stimulation treatments down the casing with a perforating gun assembly in the wellbore. The perforating guns selectively perforate the zones, which are fracture stimulated one zone at a time. Isolation between stimulated zones is accomplished by pumping ball sealers.

Permanent
Wells completed through the permanent Contact category fracture stimulate and isolate multiple stages in one pumping operation using components installed as a part of the permanent completion. Services include the following.
Multistage Stimulation
RapidSTIM stimulation and completions services enable multiple stimulations of an uncemented completion in one pumping treatment with mechanical isolation.
Multistage Fracturing
StageFRAC multistage reservoir and completion services enable multiple fracture stimulations of an uncemented completion in one pumping treatment with mechanical isolation.
Dynamic
The dynamic Contact category offers fluid-enabled tool-free reservoir of multiple stages in one continuous operation.
Shale Gas Dynamic Fluid Diversion
StimMORE Fluid-Based, Tool-Free Diversion Technology
StimMORE shale diversion service combines fluid-based, tool-free fracture diversion technology with StimMAP LIVE real-time microseismic monitoring. Microseismic data delivered while the fracture treatment is pumped allows real-time optimization of fracture treatments. The service is suited to horizontal well multiple-frac completions, both cased hole and open hole.
The StimMORE service has been developed for use primarily in the Barnett Shale formation in North America, where the temperature range is between 160 and 250 degF and where narrow fracture widths less than 4 mm are expected.
Because it is fluid-based, StimMORE diversion slurries can be pumped on the fly as part of the main treating fluid, diverting the fracture as needed. By using a multicomponent blend of degradable materials, StimMORE slurries temporarily block fractures, diverting fluid flow and inducing the creation of additional fractures along the wellbore. The slurries degrade completely after the fracturing treatment has been completed and leave no residual formation damage.
In refracturing treatments, where wells have existing perforations in place, StimMORE provides an innovative solution for fracture diversion when traditional methods such as bridge plug placement are no longer possible.
