Well Drilling Technology

DRILCO is equipped with a wide range of drilling systems capable of addressing all technical requirements under the most complicated geological conditions especially in water well drilling. Drilling methods employed are: -
  • Rotary System with Direct and Reverse Circulation Method.
  • Down The Hole Hammer drilling.
  • Cable tool Percussion drilling
  • Large diameter Auger drilling
All our drilling rigs are imported truck-mounted and track mounted solely custom-designed for groundwater exploration and capable of drilling the required diameter to depths exceeding 300
meters. They are equipped with air rotary capabilities for small or large diameter drill holes. Each rig is equipped with auxiliary high pressure air compressor and large volume mud pumps on board.

DRILCO is the first private drilling company in Malaysia to introduce the Reverse Circulation Rotary drilling method for water well drilling in exploration as well as in production. We are still the first and only private company to own this type of drilling machine. Reverse Circulation Rotary method is employed in unconsolidated formations or Alluvium, where the underlying geological settings of the site consist essentially of loose clayey-sandy-gravelly deposits commonly of extensive thickness generally found along the coasted plains or further inland along major river valleys. Reverse Circulation is proven to be the best and most successful method for drilling large diameter holes up to 915mm (36") in unconsolidated sand and gravel formations or alluvium

This Reverse Circulation method of drilling was employed successfully in one of our biggest Alluvium Drilling project in Kelantan for Jabatan Pengairan dan Saliran Malaysia (JPS) with big diameter boreholes of 406mm (16") and 610mm (24") and installation of 305mm (12") and 400mm (16") diameter steel casings and stainless steel screens respectively. With this milestone, we look forward to the drilling of much bigger and deeper structures, especially in delivering on time and within the project specifications.
