In normal mud rotary drilling, it is not unusual for solids content to approach 20 percent of returns during fast-hole drilling. This is good; it means fast penetration and thus, a quicker, more profitable hole. The trick is to get the solids out of the mud before it is returned to the hole.
In 1958, I was hired by Ward McGinnis Oil Co. in El

EarthScope is a bold undertaking to apply modern observational, analytical and telecommunications technologies to investigate the structure and evolution of the North American continent, and the physical processes controlling earthquakes and volcanic eruptions.
Drilling fluid maintenance cost, clean up and disposal cost, as well as the overall cost of boring, can be reduced dramatically when proper solids-control techniques are utilized.
Hydrofracturing is a water well development process that involves injecting high-pressure water via the well into the bedrock formation immediately surrounding it.
Sandia National Laboratories is developing technology to reduce problems caused by bit vibrations by reproducing downhole vibrations in the laboratory.
