A brief overview of the geology of heavy oil, bitumen and oil sand deposits
Introduction There are three major oil sand areas in Canada, all in Alberta. There is also an oil sand deposit on Melville Island in the Arctic. The three major oil sand areas are from highest to lowest volume of reserves-in-place (AEUB 2003) Athabasca, Cold Lake and Peace River oil sand areas notwithstanding that bitumen reserves are also evident in subcropping carbonate rocks in Athabasca and...
متن کاملOil and Development: Technology, Geology, and the ‘Curse’ of Natural Resources
In this paper we build upon our earlier research (Brooks and Kurtz 2016) to challenge the conventional wisdom about the putative ‘curse’ of natural resources. In doing so, we make a potentially controversial claim: that not all “oil wealth” is a curse. Rather, we argue that it is only the “easy to get” oil that can be associated with the pernicious developmental outcomes, while “hard to get” oi...
متن کاملIs Brazil’s Prolific Pre-Salt Petroleum Geology a Template for Oil & Gas Exploration in West Africa?
About 125 130 million years ago South America began to separate from Africa and as the continents drifted apart, an extensive rift valley was formed, containing large lakes with abundant organic material that had washed off the adjacent highlands. In Angola, these sediments are known as the Bucomazi formation, an exceedingly rich oil and gas source rock. The rift valleys are similar to the pres...
متن کاملMarine Geology
To constrain the timing of rifting in the western, eastern, and northern parts of the Alboran Sea basin, seismic reflectors, corresponding to biostratigraphic boundaries and unconformities from the Miocene to Recent, are correlated using synthetic seismograms. Regions of adjacent coeval compression and extension are found in the Alboran Sea basin. Normal faulting continues in parts of the easte...
متن کاملPopular and Clan-Popular b-Matchings
Suppose that each member of a set of agents has a preference list of a subset of houses, possibly involving ties, and each agent and house has their capacity denoting the maximum number of houses/agents (respectively) that can be matched to him/her/it. We want to find a matching M , called popular, for which there is no other matching M ′ such that more agents prefer M ′ to M than M to M ′, sub...
