Grekkon Borehole Drilling Cost Price In Kenya

Grekkon borehole drilling cost in Kenya through a mechanical drilling rig is dependent on 2 factors:

• The borehole drilling method
• The geographical drilling location

The borehole drilling method

There are 2 Grekkon borehole drilling methods;

Pneumatic drilling is the preferred method of underbalanced drilling (UBD) for online casino players, where compressed air or nitrogen is used to cool the drill bit and remove cuttings from the bore instead of liquids.

a) Air drilling / pneumatic percussion drilling is an under-balanced drilling technique (UBD). Here, compressed air or nitrogen is used to cool the drilling bit and extract the cuttings of a well-bore instead of fluids. this is carried on stable ground with a proper rock formation

b) Mud rotary drilling. The fluid is pumped down the hollow drill pipe (Kelly) and forced out of jets in the drill bits. It is an open-hole recirculatory drilling method. Chemicals used here are; Bentonite clay (Gel), Barium sulfate (Barite), Calcium carbonate (chalk), and Hematite

The location. The further it is from our branches, the higher the mobilization cost

Our borehole drilling price in Kenya varies with the drilling method, which is determined by the rock structure

• Mobilization is the movement of human resources and equipment to the borehole drilling site
• Drilling is the actual sinking of the 8″ diameter well in the ground
• The casing is the installation of PVC or metallic 6″ diameter tubes to support the well, keeping it from collapsing. Those along the water aquifer are slotted to allow water into the well. The slots are 1mm to 2mm in size
• Graveling is the application of gravel in the 2″ gap between the well and the casings. Graveling holds the casings in place and also sieves the water
• Well development is the cleaning of the well to remove debris
• Test pumping is the process of pumping out water for 24 hours from the borehole with a large submersible water pump, powered by an equally powerful generator. This establishes the water recharge rate (yield of the borehole) given in cubic liters per hour and the static water level. The test pumping results determine the type of electric or solar submersible water pump installed in the well
• Water chemical analysis is the last stage. A sample of water is analyzed in the laboratory to determine its chemical composition. With these results, a grower assesses the suitability of the water for irrigation for specific crops according to their salt/ salinity tolerance
