Continental Deep Drilling: Challenge and Chances for Geosciencesto the proceedings. But at the outset what perhaps was most impressive about this conference was to be with such a spectrum of people who study the earth, from the geological engineers with their robust philosophy to those of us normally more cautious and ambiguous in our statements.

The Ocean Drilling Programgh the recovery of samples from beneath the floors of the world’s oceans. The ODP with Texas A[amp]M University (TAMU) as the Science Operator, is the successor program to the Deep Sea Drilling Project (DSDP) operated by the Scripps Institution of Oceanography (SIO) of the University of California a

The United States Continental Scientific Drilling ProgramWe propose to tell you of the birth and early development of a program which involved protracted labor, threatened for a time to be triplets and, now, as a slightly schizophrenic individual, is struggling toward maturity. The United States Continental Scientific Drilling Program has had more than th

The NAGRA Deep Drilling Program in Northern Switzerland — Overview of Drilling Technique2500 m. The aim is to investigate the crystalline bedrock which is covered by sediments a few to several hundred meters thick as to suitability for radioactive waste disposal. The maximum length of crystalline drilled in one borehole is approx. 1500 m..Because of the strict requirements in the inves

Recent developments in scientific deep drilling in the United Kingdomific drilling in Britain had been carried out by, or for, the British Geological Survey (BGS). Approximately between 1955 and 1975, the BGS drilled numerous boreholes, some of comparatively shallow depth, to solve local geological or geophysical problems but with a bias towards resolving stratigraph
