Deep drilling resumed in 1993 to review the resource estimates and, from 1994, the " Beaconsfield Mine Joint Venture " has carried out drilling of the depth extension of the Tasmania Reef.

The following 1, 500 years saw the outpouring of a long list of Chinese inventions : canal lock gates, deep drilling, gunpowder, kites, magnetic compasses, porcelain and printing, to name just a few.

In 1938, Clark visited the oil fields of Oklahoma and Northern Texas, where his observation of deep drilling confirmed long-standing suspicions that there existed a meaningful geological column, a position adamantly denied by Price.
34.
Although available GISP data gathered over the earlier seven years, pointed to north-central Greenland as the optimum site location for the first deep drilling, financial restrictions forced the selection of the logistically convenient Dye-3 location.

High-energetic electrical plasma is a technology currently being developed in deep drilling applications to address many issues related to drilling in water environment or in the production of boreholes with a wide range of diameters.
36.
With the formation of the Yount-Lee Oil Company on December 22, 1914, Yount made his mark in the area of deep drilling, much of that on the flanks of old oil fields thought to be depleted.
37.
Because the suspected oil layers lie up to 20, 000 feet below the dunes, drillers are forced to use new and expensive wildcatting tricks, including three-dimensional seismic modeling, digital simulation and high-pressure jetting for super-deep drilling.
38.
Asked if the deep drilling might open a Pandora's box of new human ills, the discoverers generally said the subterranean microbes were adapted to an environment so hostile and alien as to greatly reduce the odds of human infection.
39.
This is because of the high outputs anticipated per well, the relatively shallow depth of the reservoirs compared to modern deep drilling, and the readily accessible onshore operations which do not suffer from severe winters which can otherwise hamper production operations.

The extra deep drilling rigs designed and manufactured at the plant made it possible to reach the depth of 13 km ( at the Kola Superdeep Borehole ) and to obtain for the first time rock samples approximately 3 billion years old.
