Narrative
The oneok pipeline was shutdown and isolated with product the night of 6/14/2017. In the morning of 6/15/2017, the pressure on the pipeline was reviewed and it was discovered that the pressure had dropped from 950 psig to 250 psig. Operations walked the pipeline with a forward-looking infrared (flir) camera and found that a 1/2 inch bleed valve on the pig receiver was leaking and product was being lost as gas. The valve was repaired by adding new thread tape and pipe dope.
