Study

After the contract has been formalized, our technical team will visit the site along with geologists to identify the best place to carry out the drilling process.

Mobilization

The drilling rig accompanied by a support truck will reach the site. Based on the soil and rock formation conditions, we would take approximately 3 hours to prepare for the drilling process.

Borehole Drilling

The drilling is carried out by using the “Down-The-Hole” (DTH) technology. This system works by using high compressed air built within our drilling rig. The size of the hole can vary depending on the requirement of the client. As the drilling process continuous, geological rock samples are taken at 2 meter intervals. Struck and water rest levels are constantly recorded. This process enables us to estimate the yield of individual aquifers encountered.

Well Casing

Once the borehole has been drilled, it must be lined with either steel or UPVC casing. The casing process keeps the well open and protects the earth, similar to the efforts to protect groundwater. The hard metal casing shores up the wellbore and extends through both the verticality and the horizontal drilling phases, assuring the long-term integrity of the well from end-to-end. In addition to providing stabilization and keeping the sides of the well from caving in on themselves, casing protects the well stream.
