Tech Division Events
International Division
The International Tech Division Events are free and open to anyone. Donuts and muffins are provided by Gore Surveys but feel free to bring your lunch. The facilities for the talks are provided complements of EnCana Corporation. For further information, to volunteer to give a talk or to list your name on the contact list , please contact Bob Potter at (403) 863-9738 or ropotter@telusplanet.net.
Division Profile
The International Division has been running since the early 1990's.The Division mandate is to provide a CSPG forum for members who are interested in learning more about the geology and hydrocarbon potential of countries other than Canada.This is achieved by holding regular technical presentations. The technical presentations vary between offering detailed investigations of specific basins or hydrocarbon provinces to more general overviews of a particular country. The talks always aim to offer some general interest geology (including elements of sequence stratigraphy, basin formation, structural geology, etc.), general interest geography, and personal insights on the cultural aspects of other countries. Also included are thoughts on the philosophy and economic imperatives of doing business in foreign places.
Our meeting schedule is to have one informal brown-bag talk every month except during the summer. Talks normally start at 12:00 noon and finish before 1 pm. Each talk consists of a 40 minute technical presentation followed by a ten minute question period. Currently, our meetings are held on the second floor of the Calgary tower in the EnCana Amphitheatre.
Involvment of our CSPG members is the key to the success of the Division.Individuals are ecouraged to take part in all activities. Service companies and students are also encouraged to attend Division meetings. The Division Chair is Geoffrey Say, of ECL Canada.
If you are interested in joining our mailing list and learning more about the International Division, or if you care to suggest a technical topic or present a talk to the division, please contact Bob at (403) 863-9738 or ropotter@telusplanet.net.
Division Talks
West Africa: Geology, Oil & Gas Production and Geopolitics
Speaker
Tako Koning,
Advisor – Tullow Oil Angola &
Residential Representative, Yme Foundation
Luanda, Angola
12:00 Noon

2nd floor, east end of the Calgary Tower Complex,

Calgary, Alberta
Abstract
Yme Foundation water project with local kids in northern
Angola.
The geology of this important oil producing area is typical of a passive margin environment. Nigeria's petroleum geology is primarily related to the sediments deposited during the Tertiary in the deltaic environment of the ancestral Niger River. Angola's oil production is related, in part, to the rift and drift tectonics which occurred in the Southern Atlantic during the late Jurassic and Early Cretaceous. In addition, the highly prolific Oligocene and Miocene reservoirs in the deepwater Congo Basin are turbidites which were deposited seaward from the ancestral Congo River. In addition to a regional overview of West Africa, this presentation will give an update on the exploration successes and significantly increased oil production which is occurring in Angola.
Other important oil and gas producing countries in West Africa include Equatorial Guinea which is currently producing about 380,000 barrels of oil per day and Gabon with production of 250,000 barrels of oil per day. The very important Jubilee oil and gas field discovered in 2007 in the deepwater of Ghana serves as a reminder that large parts of West Africa are still minimally evaluated by the drill bit.
West Africa is also becoming an increasingly important gas producing area. Nigeria is currently exporting about 14 million tonnes of LNG per year. Equatorial Guinea is now exporting 3.4 million tonnes per year of LNG. Angola is presently building an $8 billion LNG plant in Soyo, Zaire province and will produce 5.2 million tonnes of LNG per year, beginning in 2012.
The oil fields in West Africa have advantage over other producing areas such as the Middle East since the oil is low-sulphur and is predominantly light to medium gravity. Furthermore, the crude from West Africa is easily transported by tanker to refineries on the USA's East and Gulf coasts. About 17% of the USA's oil imports currently come from West Africa but the USA's National Intelligence Council projects that this will increase to 25% by 2015 thereby eclipsing even the Persian Gulf.
Biography
Tako is Holland-born but Canada-raised with a B.Sc. in Geology from the University of Alberta and a B.A. in Resource Economics from the University of Calgary. He worked worldwide as a geologist and manager for Texaco for 29 years. Tako has lived and worked for the past 16 years in West Africa including three years in Lagos, Nigeria and the past 13 years in Luanda, Angola.
After early-retiring from ChevronTexaco in 2002, he stayed in Angola and has been working as a part-time consultant for Irish-English explorer and producer, Tullow Oil. At the same time he is involved with a Norwegian NGO, Yme Foundation (www.yme.no) which is drilling for water (drinking water) and implementing water and sanitation projects in rural parts of Cabinda province near the border with Democratic Republic of Congo (DRC).
Deep Target Impedance Imaging within the Lower Cretaceous Reservoirs Continues to be Refined by Further Drilling Over the KG-OSN-2003/1 and KG-ONN-2004/1 Processed Seismic Data (2003-2008) within the Krishna Godavari Delta Basin

Abstract
An iterative application of borehole constrained velocities within the 3D seismic volume over the KG-OSN-2003/1 Block is required to image the deeper Lower Cretaceous Reservoirs in the Krishna Godavari Basin. These velocities range from 4000m/sec to 6000 m/sec changing laterally with both the structure and the age of the stratigraphic formations. Seven well log data sets, below the regional Lower Cretaceous unconformity, have been integrated with the seismic velocities to improve both the PGS acquired and processed data from 2003 six and eight streamer and 2005 eight streamer marine Ramform 3D acquired data. The results help significantly to optimize delineation wells and map reservoir zones. The methods used by GeoGlobal Resources Inc. for the operators characterize the reservoir using inversion technology. Interpretation results will be presented.
