New Initiation System Delivers Improved Perforating Safety and Reliability While Maximizing Efficiency
In the perforating industry, operators, service companies, and
manufacturers are constantly looking to improve shaped-charge performance and
product quality and reliability while ensuring the highest levels of safety.
More recently, there has been a heightened urgency to deliver improved
operational efficiency considering recent industry downturns and the need to
become more cost efficient. A new wireline perforating initiation system has
been developed that addresses current industry challenges by improving
reliability and efficiency while also improving the overall safety of wireline
The development of a new initiation system for the conventional
perforating market has built upon existing technologies previously developed
for the unconventional market. The initiator system follows the guidelines of
API RP67, fourth edition (currently in review), and has undergone
detailed testing and validation before introduction to the field. Currently,
the design is in the process of being API RP67 qualified as a Group 2
initiator, which allows use without requiring radio silence in the conventional
exclusion area. Field testing has demonstrated that the simplification of the
preparation and arming process significantly improves operational efficiency
and reduces the risk of human error. Additionally, by eliminating parts and
simplifying maintenance, system reliability and usability is further improved.
Selective guns are much simpler to prepare and arm, making the utilization of
such gunstrings more appealing in areas where, in the past, they may not have
been viable due to the additional complexity and/or associated arming time.
This new gun system is currently being deployed in several areas around
the world and has shown that it can deliver step-change improvements in
reliability and efficiency with improved operational safety when working with
explosives in wireline operations. This will have a significant impact on
perforating operations, improving the safety of the field workforce while
simultaneously improving operational efficiency.
