Oil is produced in two ways. The first way is by natural forces: the pressure of either water from the bottom or natural gas from the top is relieved when you drill a hole, and the oil under that pressure is then forced up the hole and out. The second method is by pumping, where you have a pump that creates a suction that pulls the oil up. The amount of oil that is recovered by those means is not nearly all of the oil that is in the reservoir. Some reservoirs give up as little as 3 percent of their oil; some will give up to 75 or 80 percent. This patented method started by my friend's father used CO2 mixed with water which was injected into formations, which would then cause an increased recovery of oil. I was offered the job as a vice-president at $40,000 a year, which was a nice increase for me at that point. They told me that it was going wild on the American Stock Exchange--it had gone from two to over eighty--and it was getting written up in a lot of publications, so I went to work for them. P: In Tulsa? M: In Tulsa. I found out very shortly that you could not command the big companies to license your project. Within about a year I became the general manager of the company. Our resources that we had gained from the public offering of stock were flittering away, and we had some small operators who had licensed our project, but we never succeeded in getting a large company to license the project. I was working with a large research lab. We had about forty-five people working in the lab, which was located at the University of Oklahoma in Norman. We were producing oil by the patented process, and we had a sales activity--we were out trying to sell the patented process. P: You were not involved in natural gas at all? M: No. I got involved as the principal sales agent, and we worked up a number of road trips to go out and talk to various groups of engineers and companies about this. But it never did any good. Then my wife died. The company went into bankruptcy, and, as an aside, now most of the large oil companies are using the process, but they are not paying anybody for it. P: Why did it go into bankruptcy? M: Because they could not get anybody to license the process, thus providing a flow of income. The income that they had was inadequate to maintain a corporate structure. P: Once again, it was a cash flow problem. M: My first wife died in 1963. During the period of time in Tulsa before her death, I had been approached by a social friend whose father had started a company that was based on a patented method of secondary recovery of oil.
