Petroleum Geology Of The Jubilee Oil Field, Offshore Ghana

In 1956, oil was discovered in the Nigerian state of Bayelsa, less than 50 miles south of the Delta state line. In 1958, the Delta started producing oil at around

Offshore drilling is defined as” The operation of oil wells on the continental shelf, sometimes in water hundreds of feet deep” according to dictionary.com. This method of drilling is a very common form, being used throughout different locations offshore everywhere in the world, the first being in 1897 according to howstuffworks.com. The locations of oil are found by two main methods. The first one is by finding magnetic occurrences that are in natural in the ground. If readings found a steady amount of magnetism over a general area then suddenly a large decline, they could have found the location of an oil deposit. But to ensure that is in fact a trap, the second method called sparking. “sparking is sending shock waves down through the water and into the ocean floor.” This allows ships above to be able to read the ground below and see at different locations where

Ghana itself is on the coast of the Gulf of Guinea and south of the Atlantic ocean. Burkina Faso is to the north of the country, and Togo is to the east. It has three important regions that are the coastal, forest and Savanna regions. The forest region is about one third of the country. The land of Ghana is mostly flat plain, but has many forests.

This report illustrates a geological review of a play within the South Brae oilfield and determines the potential of reservoirs within this area. It is hard to predict and provide ability for oil companies to license an oilfield before drilling therefore it is dependent upon several core sections available to investigate petrographically the northern North Sea. Cores and petrophysical data extracted from blocks 16/7a-A9, 16/7a-A17 and 16/7a-A21 related to licenses in block 16/07a found in the South Viking Graben area are provided and analysed in order to resolve whether exploration licenses should be purchased and the possible drilling of an exploration well.

As technology evolved, offshore drilling moved progressively into deeper water and farther away from oceanfront. In 1958, Richfield Oil Company developed the first drilling man-made island in Rincon where there was a substantial amount of oil was found. With the mounting pressure and high demand to produce more oil and gas, geologists studied the anticlinal trends and discovered the abundance of oil productive in Rincon Island extended underneath the Santa Barbara Channel.

Niger Delta region, placing the Nigerian oil output down to a third of its capacity” (Klare 3).

This report presents information regarding the industry, the primary operator of oil and gas field properties. The industry fuels its key buyers, the Natural Gas Distribution (22121) and the Petroleum Refining (32411) industries, with crude oil and natural gas. The industry continuously battles a shortage of available oil. In addition, many major oil fields have been in use for decades, slowly waning. Currently, the industry grosses among the most profitable in the US despite these and similar obstacles. The benefits of investing here

September 5, 1927 marked a turning point in the history of oil exploration. Before then, to assess the composition of subsurface rocks to find oil pay-zones, scientists had to rely on core samples brought up from boreholes. These were highly unreliable and drilling companies frequently missed oil zones. Conrad Schlumberger had the idea of running an electrical probe into the drilled borehole to measure resistivity through the formation. This first log taken in the Alsace region of France was a simple hand-plotted graph, but it effectively aided engineers to “view” what was inside the

“Ghana is located on the west coast of Africa, approximately midway between Senegal and Cameroon. It is bordered by Côte d’Ivoire (Ivory Coast), Burkina Faso, Togo, and the Atlantic Ocean”. (“Culture of Ghana” para 2)

uncomplicated area to study oils. In the Canadian and American parts of the Williston Basin occur

Oil shale deposit range from small presently economically recoverable reserves to large presently uneconomically recoverable resources.

Oil is one of the most important commodities in today’s industrialized world. It is for this reason that the topic of offshore oil drilling has come to take center stage in many debates and discussions, especially the political and economic ones. Offshore oil drilling refers to discoveries and developments of oil or gas resources, which lie under water. For many, offshore oil drilling is a necessity and is needed to balance the power between the oil rich countries and countries that heavily rely on them. For others, the negative of offshore drilling far outweighs the positive.

oil in Nigeria. Nigeria’s large supply of high quality crude oil helped Shell climb to the top,

As previously mentioned the project is expected to cost more than $3.7 billion and will be funded by the World Bank and the International Financial Corporation. The total costs have two major sections i.e. the Field System of more than $1.5 billion and the Export System at approximately $2.2 billion. The Field System is geared towards the development of Chad's Doba oil fields that includes the construction of related infrastructure and facilities and drilling of around 300 wells. The Export System incorporates the construction of a 670-mile, 30-inch pipeline from Chad's Doba oil fields to Kribi's Atlantic coast in

Drilled by the Transocean Leader, the 6705/10-1 well reached a vertical depth of 3,775 meters below sea. The reservoir is located in Upper Cretaceous reservoir rocks, and found gas in rocks with good reservoir properties.
