TUBING CONVEYED PERFORATING (TCP)
high reliability and less downtime with PacSci EMC
Thousands of perforations worldwide.
We design and manufactures time delays, primers, initiators and detonators for TCP service providers worldwide.
When deploying perforating guns down-hole in well environments where lateral lengths can exceed 9,000 feet, you need tubing conveyed perforating (TCP) products that are both highly reliable and cost-effective. Our years of experience translates to high reliability and less downtime, saving you time and money.
Helping Achieve Mission Success
Our products are designed to meet the most demanding high pressure, high temperature (HPHT) well environments on and off shore. Our solutions offer high reliability and less downtime to help your team achieve mission success.
Tubing Conveyed Perforating (TCP) Bottom Hole Assemblies (BHA) typically consist of a firing head, percussion initiator, perforating guns, inter-gun time delayed detonators, a setting tool initiator, and a plug. The initiator, also known as the CP Detonator, is used to reliably initiate down-hole BHA for perforating operations in the oil and gas industry.
Mechanical impact energy from a firing head is converted to detonating output by the initiator which is needed to fire the initial gun in the BHA. Mechanical transfer devices are used in between perforating guns to initiate primers or igniters for time delayed detonators to provide reliable time for pulling to the next perforation cluster. Explosive transfer devices can also be used to join redundant or duplicate energetic paths for redundant initiation trains. Precise delay times are achieved between 5 and 6 minutes down-hole and are dependent upon Bottom Hole Temperatures (BHT). For more efficient operations, over thirty (30) time delay detonators have been reliably functioned on a single run in-between perforating guns. For plug and perf operations, mechanical impact energy from a firing head, or transfer device, functions a rapid deflagrating material (RDM) initiator which is used to reliably ignite propellants in setting tools to assure consistent burn rates prior to plug separation.
TCP initiation and transfer devices can be used in applications requiring reliable instantaneous high order detonation, setting tool/propellant ignition, and time delayed detonation. Time delays can be used to provide time after BHA initiation to improve overbalance or under-balance conditions, conveyance to separate zones in between guns, and bleed off nitrogen in order to improve efficiency and production.
