The Fayetteville Express Pipeline, recently constructed by Sheehan Pipeline Contractors, kicked off near Bald Knob, Ark., and ended southeast of Conway, Ark. There were two spreads on this section of the line.
Dykon Blasting Corp. was contracted to perform the drilling and blasting for both spreads of this project. The timeframe for the completion of this line was aggressive, and called for more than a mile a day of production. Several crews were utilized with up to 15 drills operating at one time to meet the production requirements for this project.
This project presented some unique challenges in that it paralleled three existing high-pressure gas transmissions lines for much of the way. These existing operational lines were in production during the time of construction, and were as close as 45 feet to the drilling and the blasting. Strict vibration limits on the existing lines made this project uniquely challenging, especially with the presence of extremely hard sandstone, with a compressive strength in excess of 15,000 psi.
