I have been posting stories for almost three years, and just suddenly remembered this incident that could have been potentially deadly for three men, one of which was my father.
I am not sure of the actual year, but I am probably 10 to 12, and it is winter time. The ground is frozen and partially covered with sleet. Suddenly, the gas flow pipe from Lone Star Gas Company delivering natural gas to repressure the field burst. It sent a plume of gas, natural gas condensate, and water at least 20 feet or higher into the air.
Dad, the field manager, Jesse Shields, and Buck Pickett immediately jumped in to fix this leak and get it under control, despite the absolute danger. Lone Star Gas crews could have managed but they would have been several hours in arriving and it needed immediate attention.
Two other men were sent in opposite directions to stop all auto traffic coming from either direction to prevent their cars from setting off an inferno! Dad and his boss were immediately digging a pit around the eruption so they could fit a saddle clamp over the rupture and stop it.
While there was gas in a vapor, liquid or condensate gas, and water, it was all quite flammable. While I am at most 12 years old, I knew enough about our business I recognized the real chance that if it got one spark, all three men would be incinerated immediately, and would not have a chance to survive the possible inferno! Talk about scared, I could hardly breathe. This break was only about 15 or 20 feet on the other side of our driveway and garage.
Although all three men were completely soaked with drip gas or ‘midnight ethyl’, they were digging as fast as they could to expose the area of the break. This was a 2 ½ to 3-inch black pipe and had built up enough water extracted from the air to have an ice plug which was the reason for the break. They did this as quickly as possible because any other help called upon would take hours to arrive. This leak had to be stopped as quickly as possible.
As soon as they had cleared a space around and under the pipe for a clear work area, they placed this saddle clamp and then tightened the two or three bolts on either side to securely fasten the clamp over the rupture and stop the leak. It is not every day you see something so potentially dangerous right at your doorstep and your father had to dive in and help correct this accident.
I know a lot of folks are not familiar with why an oil field is repressured with natural gas. There are four stages of field production. 1st stage is when the drilling of a well strikes pays sand, and there is enough gas pressure to cause it to flow naturally. 2nd stage after the gas pressure has dropped, for it to be pumped, that is why a mature field will have pump jacks working on each well. The next phase is repressuring the field with natural gas to force more crude to the surface. Finally, the last and final phase is saltwater flooding to recover the remaining crude. Our field was in the natural gas repressurization phase. The equation is the cost of natural gas repressuring is less than the crude oil recovered.
Up until recently, a field was abandoned after salt water had scavenged all the crude and that was pumped to the surface. However, George Mitchell and Mitchell Energy had made a great discovery and mastered how to penetrate the Barnett Shale and drill even deeper, making the discovery of both new sources of oil and gas available. Sometimes this new source was even greater than the original discovery. When other companies saw Mitchell’s men buying up areas of old, worn-out leases, while they didn’t know the reason, they got busy and started similar efforts themselves. Many royalty owners got surprisingly greater checks once these deeper wells were completed. In fact, the entire population of the U.S. benefitted from the greater amount of natural gas all at a lower price due to Mitchell Energy’s efforts. Just Sayin…RJS

You are exactly right about the danger, Mr. Samples. Been there, done that.
