The present work deals with an interpretation of well log data (gamma ray (GR), resistivity, density, and neutron) from four wells, namely P-1, P-2, P-3 and P-4 in the study area of the Rio Del Rey basin. The well logs analysis indicates five potential sandstone reservoirs at the P-1, two at the P-2, four at the P-3 and six at the P-4. The neutron–density-GR logs highlight the sandstone gas reservoir characterized by high resistivity and crossover between neutron density. The neutron–density-GR cross-plot confirms the presence of sandstone containing hydrocarbons by a displacement of the cloud of points, from low to medium GR values, from the sandstone line to the left. Petrophysical parameters exhibit the value 12–41% for a volume of shale, 15–34% for effective porosity, 29–278 mD for permeability and 3–63% for water saturation. The three potential hydrocarbon reservoir saturation ranges from 22 to 45%. The study will contribute to future offshore oil and gas exploration and development in the Rio Del Rey basin, based on the geological and geophysical characteristics of the reservoirs delineated.

This paper deals with resources and opportunities of direct and indirect use of geothermal energy in Cameroon. Currently, no serious exploration and utilization of this resource exists. The primary form of utilization of geothermal energy is mainly condensation steam for drinkable water. Despite the availability and enormous potential in direct use applications, no use has been made of low enthalpy fluids. Several geothermal sites were identified using thermal methods. The results obtained from the geothermal gradient of Cameroon revealed the presence of temperatures able to produce electricity in the hottest spring of Woulndé (600°C). Other applications of geothermal energy in Cameroon are also discussed.
