Tubing Conveyed Perforating Services

Our TCP systems effectively perforate vertical and deviated wells in an under-balance, balanced and over-balanced situations

Our Tubing Conveyed Perforating systems effectively perforate vertical and deviated wells in under-balanced, balanced and over-balanced situations, offering customers a safe, efficient way to optimize well production. Because long intervals can be perforated in a single trip, our TCP saves substantial rig time, making it cost efficient.

We offer TCP services designed to meet our customers’ varying needs and specifications including the following systems:

Eunisell Solutions as the single point of contact allows greater efficiency in test design and single point Service Quality accountability.

TCP Applications

Closed-Chamber Surge-and-Test Application
TCP string is used to provide a controlled surge volume by allowing the well to flow through the surge chamber. The surge chamber is initially run empty and then opened to the formation by the lower tubing isolation valve.

Dual String Multizone Selective Completion Application
In a permanent completion, the completion string, including all downhole hardware and guns, is conveyed into the well on the production tubing and spaced so that the guns are opposite multiple zones of interest after the packers are set.

Downhole Temperature Versus Expected Time Exposure
Downhole temperature and expected time exposure are among the most important parameters to consider when planning a TCP operation.

Re-perforation with Packer Set between Existing Perforations Application
In this application a well may be reprobated or a new zone perforated with open perforations in the well.

Stab-In Completion Application
In a permanent completion, the packer and sealbore assembly are set on wireline, and the guns are conveyed on the production tubing and stung into the packer.

Single-Trip TCP-Acid Frac-DST Application
Using this string, a well may be perforated, acid fractured and tested through a DST string on a single trip into the well.

Sting-Through Completion Application
In a permanent completion, the packer and sealbore assembly are set on wireline, and the guns are conveyed on the production tubing and stung into the packer.

Single-Trip Perforate and Gravel-Pack Application
A well may be perforated and gravel packed on a single trip into the well. The underbalance is created by circulating a lighter fluid through the packer bypass. After firing, the guns automatically drop, allowing the packing operation to proceed.

Single-Trip Selective Firing, Commingled Production Application
With this string, a well may be selectively perforated on a single trip.
