Halliburton collaboration saved operator over USD 500,000

Overview 

A large Dutch operator wanted an electronic firing system that would complement its wireless communication system for a drillstem test (DST). The electronic trigger that would be used could not compromise the need for nitrogen in the underbalance. The underbalance was designed to provide maximum effective perforations and prevent damage to their formation from wellbore fluid invasion. An additional focus for the client was safety and operational flexibility as a contingency if there was any potential for unplanned wellsite operational changes. Halliburton recommended its MaxFire® electronic firing system (EFS), which successfully initiated the perforating string in an underbalance condition with a low actuating pressure. The ability to capture, pressure, temperature, and time at the perforated interval—before, during, and after the event—later proved to be very valuable. This is the first run of the MaxFire® EFS in The Netherlands

Challenge 

Operator wanted to use an EFS that would complement the wireless DynaLink® communication* system used for the drillstem test. This electronic trigger couldn’t compromise the need for nitrogen to incorporate the underbalance.

Needed a contingency plan focused on safety and operational flexibility for unplanned wellsite operational changes.

Desired an independent digital accounting of job operation.

Solution 

The MaxFire® EFS is a safe, precise, and adaptable perforating control tool that can initiate a gun system through a predetermined sequence of pressure cycles.

Firing can be aborted with reset pressure at any time, and the tool can last up to 30 days in extreme downhole conditions – the longest in the market.

The MaxFire EFS records temperature, pressure, and time before, during, and after the perforation event.

Result  

The perforated interval was at 12,000 ft (3,660 m) and was accomplished with 1,450 psi (100 bar) underbalance. The MaxFire® EFS initiated the perforation event with a low actuating pressure. The underbalance was achieved with a nitrogen displacement.

With round-the-clock full support of Halliburton’s Global Team and effective communication with the operator, the job was successfully executed as planned, saving the client USD 500,000.

The tool captured before, during, and after perforation event data which was provided as a post-job report.
