Perforating Cased Hole

Tubing-Conveyed Perforating (TCP) Guns

Weatherfords tubing-conveyed perforating (TCP) guns enable operators to optimize well flow by detonating high-performance, deep-penetrating shaped charges that maximize perforation length and entry hole size. TCP guns treat zones with drilling, cement, or perforation damage and also initiate formation breakdown during hydraulic fracturing, with pressure ratings up to 30,000 psi

(207 MPa).

Adaptable to any application Run on pipe with most completion applications Run with wireline under permanent and/or retrievable packers

Applications

Low-debris and zero-debris charges are available to fit required application, providing increased flexibility.

Gun lengths and assemblies can be customized for each application, enhancing operational efficiency.

TCP guns permit operations at substantially higher underbalanced pressure differentials to ensure better perforation clean up. Large-diameter, multiphased casing guns increase perforation depth and diameter, resulting in a perforation with minimum restriction and higher productivity.

Because TCP services perforate long intervals in a single trip, substantial rig cost savings are realized. Also maximum perforation cleaningwhen perforating underbalancedcan only be achieved by perforating the entire zone at one time. TCP guns enable maximum potential to be obtained from a perforation, decreasing stimulation costs. Because pressure-control equipment can be installed before perforating, kill fluid costs are reduced.

TCP assembliesessentially large casing gunssafely and efficiently protect personnel and equipment. With TCP guns there are no electronically detonated blasting caps in the system, which means no premature or accidental firing because of stray electrical currents. TCP guns also can be run regardless of temperature, H2S, or CO2 levels.
