Vantage logging head system saves operator USD 760,000 in additional runs.
Modular CT logging head system
Available in both 1 11/16 and 2 1/2 in, the Vantage modular CT logging head system is designed to standardize e-line coiled tubing connectivity. Its increased reliability, modular interchangeability, and uniquely designed bayonet CT connector reduce rig-up time. And its 3-bbl/min flow-through capability speeds operational time.
The Vantage system's modular plug-and-play connections physically and electrically couple the components. These connections enable rapid interchangeability and reduce NPT. Together, the CT flush-OD bayonet connector and cable termination tool enable pretermination of the electrical connection before the CT is stabbed through the injector head chains. The Vantage system can perform multiple runs in hole without redressing.
High-strength, corrosion-resistant alloy materials protect the Vantage system from excess abrasion and wear, making it ideal for offshore, land, desert, and arctic environments—and for oil, gas, and injector wells. It is rated for a working pressures of 13,500 psi, maximum temperature of 375 degF, and maximum tensile strength of 40,000 lbm.
One of the main challenges in a CT e-line intervention is performing
the operation as quickly as possible without equipment failure
(loss of signal in the middle of the logging run). Assembling
the electrical terminations at the end of the CT usually requires
a significant amount of rig-up time. When multiple runs are
needed, regular maintenance of the assembly is necessary to
ensure adequate performance, which further increases rig-up
time. In addition, when perforating is performed in the same
intervention, the risk of BHA failure increases.
