Another type of potential CCS location is depleted oil & gas reservoirs. In these kinds of locations, there would typically be much more data available initially for the technical assessment of the storage capability and any potential integrity issues. Existing well records, production data, and geophysical surveys would be useful […]

The East African Rift System is a well known source of Geothermal Energy in Africa, but there is potential for low to medium enthalpy heat resources in more than 25# African countries associated with intrusive plutonic rock formations. Often these locations have been the site of shallow mineral exploration and […]
There are good technologies to capture Carbon and tens of thousands of suitable subsurface locations for Storage. With the continued use of carbon based energy sources and processes during our Energy Transition, we should be rapidly scaling up CCS.
As we have discussed previously, there are multiple options for where to store CO2 in CCS scenarios. One such location is sometimes found when reviewing end of life oil or gas reservoirs looking for Geothermal opportunities and instead identifying a depleted reservoir suitable for CCS. The Circular Economy concept needs […]
We cannot pretend that the use of carbon based fuels or carbon based industrial processes will not continue for some time. The reality is that there are tens of thousands of locations with significant carbon emissions. We have the technologies to effectively mitigate these emissions now, but there are some […]
Today’s post is (25) South Sudan. Several rift basin features with uplifts and faulted blocks offer geological conditions potentially conducive to accessing higher heat flux at reasonable well depths. Existing oil exploration and development wells may provide evidence of elevated bottom hole temperatures and aquifers in some of these areas. […]
Today’s post (22) Mauritania has been fortunate to find offshore hydrocarbons to add to existing mineral developments, but there are significant freshwater and energy challenges. There are geological structures with significant heat flux and good geothermal temperature gradients that offer the potential of Geothermal Energy. Hybrid renewable energy systems with […]
Today’s post (18) is Egypt. The presence of the Red Sea failed rift and pulses of volcanism have led to significant heat flows and thermal springs along either side of the Gulf of Suez. Some of these springs have been shown to originate from high crustal heat flow and fault […]
In a series of informational posts about the Geothermal Energy Potential in Africa, we have up to now posted about: (1) Africa as a whole; (2) Cameroon; (3) Ghana; (4) Kenya; (5) Namibia; (6) Nigeria; (7) South Africa ; (8) Zimbabwe; and (9) the East African Rift System (EARS). Now we […]
Technically Well Established and Commercially Feasible with Carbon Taxes and Cross-Border Duties As we have looked at end of life oil & gas assets to investigate geothermal potential, it is common to find some reservoirs that are not suitable for geothermal, but are well suited for Carbon Capture and Storage […]
Nigeria is a country blessed with significant conventional oil and gas resources, but there is a significant source of clean, persistent renewable energy beneath the surface also – Geothermal Energy. With good geoscience and well data, there may be an opportunity to repurpose some end of life oil and gas […]
For those more familiar with conventional oil & gas resources, it is convenient to make a comparison showing similarities and differences: Oil & Gas Geothermal Energy Source Rock – fine-grained sediments with sufficient amounts of organic matter, which generate and release hydrocarbons able to migrate upwards;Fluids – hydrocarbon oil & […]
