Development in petroleum exploration offshore West Greenland during 1977

Three-dimensional electromagnetic holographic imaging in offshore petroleum exploration

Off-shore petroleum exploration nowadays routinely uses the marine controlled-source (MCSEM) survey, which consists of a set of sea-bottom receivers and a moving electrical bipole transmitter. We show that the MCSEM survey with its dense system of transmitters and receivers, is extremely well suited for application of the holography/migration method. The combined EM signal in the receivers form...

Monitoring of Hydrocarbons in Benthic Crustaceans during Offshore Drilling and Petroleum Exploration

As part of a broad, multldlsciplinary effort to monitor the impact of petroleum exploration activities on the outer continental shelf areas of the Gulf of Mexico, the local effects of a drilllng rig on the benthic environment have been investigated. Petroleum hydrocarbons in or on seawater can become associated with suspended sediment partlcles I and be transported downward and incorporated int...

Environmental radioactivity in Greenland in 1977.

Measurements of fallout radioactivity in Greenland in 1977 are reported. Strontium-90 (and Cesium-137 in most cases) was determined in samples of precipitation, sea water, vegetation, animals, and drinking water. Estimates are given of the mean contents of 90Sr and 137Cs in the human diet in Greenland in 1977.

Micropaleontology in Petroleum Exploration

One of the aims of micropaleontological studies is to unravel the geological history of the surface of the earth in a manner that can be achieved as reliably, in relatively quick time and at the same time be economically be reasonable. Oil companies, who invest hugely in this high risk business of oil exploration, have undoubtedly gained much from micropaleontological studies. This is because o...
