13 – Safety is Priority One

A few years after the first commercial use of shaped charges, oilfield services companies directed some of their attention away from product performance and considered an additional topic: safety. An accidental detonation of a shaped charge could damage equipment and the wellbore. Such an event could also be deadly to Read more

12 – Stop the Interference

Oilfield services companies knew that recovering oil and gas required numerous perforations in relatively thin formation layers. To obtain the maximum perforation of these layers, companies developed carriers housing multiple shaped charges placed within a few inches of each other. Field experience with these carriers frequently showed disappointing results; the Read more

11 – Control the Waves

Companies that offered shaped charge perforation regarded deep perforation depth as crucial for their sales. Some oilfield services companies sought to increase jet penetration to offer a better product than competitors. Determining methods to improve jet penetration became a priority. One way to achieve this goal was to control the Read more

8 – Shoot and Retrieve

Clyde Davis was a gifted engineer who worked at the Eastern Laboratory of the E. I. DuPont de Nemours Company (DuPont). During World War II, he and his design group determined optimum values for parameters used in making shaped charge weapons, including the bazooka rocket warhead.1 The end of the Read more

7 – Shoot and Leave

Quick question: What do wood, plastic, cardboard, cement, paper, steel, glass, and aluminum have in common? Answer: They were all considered as materials for expendable shaped charge carriers. Selecting the Best Material Oilfield services companies knew they had to detonate multiple shaped charges to perforate a formation adequately and enable Read more

5 – Creative Ideas Appear

In the 1945 to 1947 timeframe, enthusiasm and optimism was high about possible uses of shaped charges, as were creative ideas that appeared in patents submitted to the U.S. Patent Office. A trio of engineers at the Gulf Research and Development Company (GRDC) in Pittsburgh exemplified this attitude. Morris Muskat, Read more

4 – Announcing the Shaped Charge

Robert McLemore, a petroleum engineer who worked at Well Explosives, Inc., had to answer a question: How could he effectively inform the industry and potential clients that his company had shaped charges available for the oil field? He determined the answer would be articles published in well-known industry magazines. In Read more
