Narrative
At 12:00 on 11/07/2015 a crew was excavating the rocky mountain northwest lateral to perform rehab work when they detected the presence of gas in the area. After investigation, it was determined the source was a pinhole in a girth weld. The line was already shut down. A plidco clamp was placed on the lines. The line was restarted on 11/23/2015 to perform a leak survey with flame ionization detection capabilities. No additional leaks were detected. **9/9/2016 update to the report** on 5/26/2016 a cutout was made and was sent in for metallurgical analysis. The feature that led to the leak was determined to be preexisting from the original construction. Upon completion of the cutout and replacement, the line was restarted on 5/31/2016.
