What is Air Drilling?

Air drilling technology is considered to be a cost-effective drilling method for operators – requiring minimal cleanup and disposal of fluid on the surface. Another huge benefit of air drilling is that it’s faster, but operators usually only drill the first 30-40 degrees of the curve on air.

The Cuttings Conundrum: SplitBlade Enhances Cuttings Evacuation and Improves Efficiency

This article first appeared in the June 2018 Edition of Oilfield Technology. 

Chris Casad, Ulterra Drilling Technologies L.P., USA, discusses how new drill bit designs enhance cuttings evacuation and improve efficiency.

The push to address a longstanding problem has led to a new development in drill bit design.

The problem relates to the commonly held belief that the poor evacuation of cuttings from drilling operations can significantly limit bit performance, and ultimately the rate of penetration (ROP) – a major concern in drilling operations.

Weight On Bit – WOB

What is Weight on Bit or WOB?

An essential part of the drilling process is adding force to the drill bit in order to successfully break the rock. Weight on the Bit, or WOB, is the amount of downward force exerted on the drill bit provided by thick-walled tubular pieces in the drilling assembly that are known as drill collars. The downward force of gravity on these steel tubes provide force for the drill bit in order to effectively break the rock.
