Spudding-In Marks Progress for Tanzania’s Geothermal Aspirations

Posted on : Friday , 26th March 2021

The principal research and innovation engineer at Tanzania Geothermal Development Company, Eng. Chagaka Kalimbia announced on LinkedIn the successful spudding-in of the 1st geothermal well in Tanzania.

 

The well Kiejo-Mbaka KMB-01 was spud-in on 22 March 2021 at around 11:09 am EAT stated Eng. Kalimbia, the project lead.

 

The planned works on the project currently consist of drilling 3 shallow wells each to a maximum measured depth of 300 mtrs. The final set up will include drilling infrastructure works such as access roads, water supply and drill pads.

 

The Kiejo-Mbaka shallow wells drilling project will not only set the stage for future drilling works but also will “go down in the history as a demonstration of Tanzania Geothermal Development Company and undeniably the dedication of the Government of Tanzania towards accelerating the development of geothermal resources in Tanzania,” said Eng. Kalimbia.

 

Geothermal Spudding-In Just the Start

 

The commencement and successful completion of the project will largely unlock a slice of geo-scientific comprehension of the Kiejo-Mbaka geothermal system, an important attempt towards the entire development of the prospect.

 

The objective of the current slim-well drilling programme is to precisely locate and verify the existence of geothermal resource, determine reservoir characteristics (temperature, alteration minerals, permeability and fluid chemistry) and estimate the ability of wells to produce geothermal fluids.

 

Another objective is to define the thermal gradient over the area and establish the configuration of the thermal anomaly and preliminary test the conceptual model.

 

When sufficient discharge of hot waters from the wells is established, the wells will be prematurely used for direct use projects. The drilled wells will empower access of the hot geothermal fluids, and then transfer it through pipelines to the various direct use pilot projects, after which the fluids will be returned to the reservoir.
