Prospecting for oil in the the early 20th century had come a long way from the days of riding around the prairie on a horse and drilling wherever your hat fell off. Even so, however you looked at it, the extent to which a geologist could predict the subsurface structure was limited. Anticlines might have been the classic indicator of an oil-bearing structure, but only drilling could prove its presence and then often by chance. The advent of ‘remote’ sensing fundamentally changed this.

Fundamentals of Petroleum Geology Physical Geology Chapter 5 Fundamentals of Petroleum Geology

The initial step in acquiring a board understanding of the drilling technologies is the development of some basic understanding of petroleum geology. To understand some of the engineering requirements in oil field drilling operations requires a comprehension of the nature of the formation to be drilled. Historically, geological studies have been concentrated in the area of the utilization of geological data as a means of locating formations having economic value. The following discussion is intended to provide the geological background needed for sound well planning and engineering. Specifically, this discussion will include information concerning the theory of the origin of subsurface formation, composition of formation, formation structural differences and rock mechanics. Simply stated, the intent of this section is to answer some of the basic questions concerning the nature of the formation being drilled, such as: How were rocks formed? What are they made of? How are they structured? How do rocks behave when a hole is drilled in them? 5.1 Physical Geology Relatively few of the problems of geology are so simple that they can be solved by one method of approach. Many geologic problems require supplementary investigation using the methods, data, and theories of chemistry, biology, physics and engineering. In turn, geology has contributed data and ideas to these bordering sciences. In the natural sciences, progress in one advances all the others. Physical geology is concerned with the physical processes that operate on and within the Earth-the processes that have given the rocks of the Earth's crust their composition and structure, and the forces that have shaped its surface. Many separate sciences contribute to the broad field of physical geology. Among the more important are: mineralogy, the science of minerals; petrology, the science of rocks; structural geology, the science which seeks to interpret the structures seen in the rocks; and geomorphology, the science which deals with the origin of landscapes. Also closely associated with physical geology is historical geology, the science that traces the evolution and development of the Earth and its plants and animals. This science draws extensively on paleontology, which deals with the study of animals and plants of the geologic past. It also draws on stratigraphy, the science

THE ROLE OF GEOSCIENTIST IN THE EXPLORATION FOR PETROLEUM

This is a course work (titled "Risk analysis in Petroleum Exploration" with code "AGP 502" assignment on discussing the roles of geoscientist in the exploration for hydrocarbon. Petroleum is one of the major commodities around the world, stored in good reservoir rocks in the subsurface or occuring as seepagaes or more recently in the source rock producing it. Geoscientists study the Earth's structure and formation, and analyse rocks to explore its natural mineral and energy resources (In this case Petroleum). In this coursework assignment I have described the roles of Geologist, Geophysicist, Geochemist, Paleontologist and Geotechnic Engineer in the exploration for hydrocarbon.

Petroleum geological activities in 1991: reassessment of earlier exploration, and improvement of information service to industry

Rapport Grønlands Geologiske Undersøgelse, 1992

The shift of emphasis in the petroleum-geological activities of the Geological Survey of Greenland (GGU) from East to West Greenland that was described in the Report of Activities 1990 was consolidated in 1991 in so far as onshore activity is concerned, as the main onshore field activity was in the Cretaceous-Tertiary outcrops in central West Greenland. Offshore West Greenland, reinterpretation of industry data from the 1970s was continued (see Chalmers, 1990). In May processing of the 5200 km seismic data acquired offshore West Greenland in 1990 was completed and interpretation of the data began, and in July two supplementary lines totalling 336 km were acquired offshore West Greenland using the KANUMAS project's vessel Thettis prior to its departure to North-East Greenland. Any geographical bias there may be towards West Greenland is however subsidiary and largely coincidental to the overall current emphasis in GGU's petroleum-geological activities, which is the reassessme...
