PROJECT DETAILS
The Fayetteville Express Pipeline, constructed in 2010 by Sheehan Pipeline Contractors kicked off near Bald Knob, Arkansas and ended southeast of Conway, Arkansas. There were two spreads on this section of the line.
Dykon Blasting 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 over 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′ 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.
