The Jim Ellis Story


As the founder and president of Ecosse Inc Jim developed the concept for and created the PX-1 fireset instrument which he would go on to provide to the Oil and Gas community.

Jim was born in Edinburgh, Scotland on September 9, 1953. Jim made the move to Houston in 1985 while he was working for Western Atlas. It was here that Jim developed a firing system for the Atlas EBW detonators which was embraced by many operators in the North Sea area. However, Jim was not satisfied, and little did he know he would end up forever changing the course of “safe” perforating in the Oil and Gas industry.

He did this by asking the question: “Yes, but what if we could make it disposable?” The system would only have to work one time and it, subsequently, could be much less expensive. From this idea, the Guardian system was born; a disposable fireset which was the forerunner of all the systems we see in our industry today.

In 1996, Jim established his company Ecosse, Inc.  He created the Company concept at his house, in his living room. Continuing to raise the bar on the design, Jim created the PX-1. Ecosse and the PX-1 have become synonymous with “safe” perforating, and his former employer, Baker Atlas, subsequently became one of his biggest customers.

It is this company, now known as Ecosse Design Inc., which continues Jim’s legacy today.
