Abstract
IT is perhaps not generally known that the long-projected depth of a 10,000 ft. oil-well was reached recently by the drilling of a hole to 10,030 feet in Ventura County, California, by one of the leading petroleum corporations in that State. The well was actually a ‘wild-cat’ put down to prove a possible extension of the Rincon field, though undoubtedly there was behind the venture a determination to create a depth record. Drilling was started in 1929, delay in completion occurring as a result of fire and technical difficulty last year.
