Abstract
The “kaolinic porridge” is described as one of the saturated zones within the weathering profile of most igneous and metamorphic rocks in Ghana. The zone is comprised of clay and fine‐grained micaceous materials and is regarded as an important ground‐water reservoir. Due to its fluid nature and the fact that its depth and thickness cannot be predicted, precautionary measures are taken when drilling. Special well design, construction and completion techniques have been adopted to exploit this aquifer successfully. Yields averaging 220 gallons (about 1 cubic meter) per hour can be produced from such aquifers.Keywords
