28 May Borehole Drilling in Kenya
Drilling Methods in Kenya
Borehole drilling in Kenya is conducted in two distinct ways. Grekkon Limited chooses which method to drills your borehole based on your hydrogeological survey report.
- Air drilling or pneumatic percussion bore hole drilling in Kenya is an underbalanced drilling (UBD) technique. Here, usually compressed air or nitrogen is, used to cool the drill bit and lift the cuttings of a wellbore in place of conventionally used liquids. It’s Grekkon Limited’s drilling method when you have hard rock underneath. It is cheap, ranging from Kes 5,500 per meter. The cost depends on the precise location of the borehole in the country. This borehole drilling method is the most common one in Kenya.
- Mud/ Water drilling. We optimize it in unconsolidated, alluvial and loose geological formations. Mud borehole drilling builds a mud wall cake on the perimeter of the borehole. It keeps loose deposits stable during drilling. Mud drilling of boreholes is used to aid the cuttings out of the borehole. This method has the ability to through unconsolidated ground formations and achieve borehole stability.
We use this when you have lots of sand or very soft rock that could easily collapse in during drilling. It’s more technical and also more expensive from Kes 9,800 per meter. Mud drilling is the most prevalent method in Mombasa, Kilifi and Kwale counties.
Borehole Drilling Charges
Grekkon Limited’s borehole quote covers; drilling, casing, test pumping. A complete water chemical, and bacteriological test result is availed on request. It is during test pumping that we determine which submersible pump is optimal for your water needs. We install both solar or electric submersible pumps. Solar pumps are more popular because the entire nation receives 12 hours of sunshine near all year round. Electricity is expensive too in Kenya particularly for commercial use.
