Drilling

DRILLING

At Harbour Bridge Energy, we carry out drilling services that indicates the whole complex of operations necessary to construct wells of circular section applying excavation techniques. To drill a well, we carry out the following actions simultaneously:

• To overcome the resistance of the rock, crushing it into small particles measuring just a few mm;
• To remove the rock particles, while still acting on fresh material;
• To maintain the stability of the walls of the hole;
• To prevent the fluids contained in the drilled formations from entering the well.

After having drilled a certain length of hole, in order to guarantee its stability it has to be cased with steel pipes, called casings, joined together by threaded sleeves, Then space between the casing and the hole is then filled with cement slurry to ensure a hydraulic and mechanical seal.
