Abstract Hydrocarbons are bypassed in known fields. This is due to reservoir heterogeneities, complex lithology, and limitations of existing technology. This paper seeks to identify the scenarios of bypassed hydrocarbons, and to highlight how advances in reservoir characterization techniques have improved assessment of bypassed hydrocarbons. The present case study is an evaluation well drilled on the continental shelf, off the West African Coastline. The targeted thin-bedded reservoir sands are of Cenomanian age. Some technologies for assessing bypassed hydrocarbon include Gamma Ray Spectralog and Thin Bed Analysis. NMR is important for accurate reservoir characterization of thinly bedded reservoirs. The measured NMR porosity was 15pu, which is 42% of the actual porosity. Using the measured values gave a permeability of 5.3mD as against the actual permeability of 234mD. The novel model presented in this paper increased the porosity by 58% and the permeability by 4315%.

The Brain

Theatre Pedagogy holds that cognition is body-based. Through performance the body’s unconscious procedural memory learns. This information learned through repeated interaction with the world is transmitted to the brain where it becomes conscious knowledge. Theatre Pedagogy in this case study is based on the implementation of a Caribbean cultural art form in performance, in order to teach Francophone language and literature at the postsecondary level in Jamaica. This paper describes the experience of “doing theatre” with seven university students to learn the French language and literature based on an adaptation of two of Birago Diop’s folktales. In the process of learning and performing the plays, the students also understood some of the West African cultural universals of life which cut across the lives of learners in their own and in foreign cultural contexts.

Stratigraphic Sequences

This study presents petrophysics analysis results from two wells located in the Arafura Basin. The analysis carried out to evaluate the reservoir characterization and its relationship to the stratigraphic sequence based on log data from the Koba-1 and Barakan-1 Wells. The stratigraphy correlation section of two wells depicts that in the Cretaceous series a transgression-regression cycle. The petrophysical parameters to be calculated are the shale volume and porosity. The analysis shows that there is a relationship between stratigraphic sequences and petrophysical properties. In the study area, shale volumes used to make complete rock profiles in wells assisted by biostratigraphic data, cutting descriptions, and core descriptions. At the same time, porosity shows a conformity pattern with the transgression-regression cycle.Keywords: petrophysics, reservoir characterization, Cretaceous, transgressive-regressive cycle

Simultaneous Implementation

This article broadens analytic perspectives on the effects of government interventionsby looking at the interaction of two distinct but simultaneous policy initiatives: involuntary resettlement and structural adjustment. Case study data from the Bafing valley in Mali show that simultaneous implementation of these two initiatives reinforced the economic growth of the zone but increased negative environmental effects.Key Words: Mali, resettlement, structural adjustment, sahel, environmental degradation, economic development, river basin development, privatization, liberalization.

This paper deals with the marine fisheries off the West African coast, between the Straits of Gibraltar and Mauritania, an area which is characterized by its relatively narrow continental shelf, the presence of the Canary Current, and intensive upwelling resulting in very high primary production and rich bottom fauna.The main fisheries (for sardines, sardinellas, hakes, sparids, cephalopods, and demersal crustaceans) are analyzed with regard to their evolution, species composition, fishing areas and seasons, the biological characteristics of the exploited stocks, and the effect of fishing on them.The criteria to be considered when planning the control and regulation of these fisheries are also analysed.
