Producing More Oil from Fewer Wells
Horizontal drilling, one of the most advanced drilling technologies, makes it possible to drill nearly 2,000 feet or more to the left or right, rather than just directly below the drilling pad, allowing us to produce more oil from fewer wells.
The Horizontal Drilling Process
Step One
The horizontal drilling process begins by first protecting underground freshwater sources. The well hole is drilled to the rock below the freshwater aquifer where steel casing is inserted and cemented to seal off the well from the aquifer.
Step Two
The process of drilling and cementing casing in the hole, which ensures the well’s long-term integrity, continues for approximately two miles to just above the potential oil formation.
Step Three
The drill pushes through the potential oil formation. If the presence of oil is confirmed, a specially designed drill is then used to push the well hole horizontally 2,000 feet or more to the left or right.
Step Four
An electric submersible pump is inserted into the well and the drilling rig is replaced with a small well head. The pump then pulls the oil from the formation and brings it to the surface.
