Abrasive formations, shale wells drive new bit designs for hard-rock, high-temperature drilling
Posted on 30 April 2010 in 2010, Drill Bits, May/June
With the growth of the North American shale plays, it’s not surprising that bit companies are aggressively working to meet the challenges of drilling in the these plays, with new designs or…
Case study: new concentric expandable reamer tool used in Gulf of Mexico
Posted on 30 October 2009 in 2008, Downhole Technologies, Drill Bits, September/October
By Steven Radford, Will Thompson, Hughes Christensen; Mark Jenkins, INTEQ In the deepwater Green Canyon section of the Gulf of Mexico, an operator lost 10,000 bbl of synthetic oil-base drilling mud in one well before finally abandoning the project. In cooperation with two Baker Hughes companies – Hughes Christensen and INTEQ – the operator began [...]

Tough directional TCIs deliver longer runs with higher ROP in Canadian build sections
Posted on 30 October 2009 in 2008, Drill Bits, July/August
By Chad Mason, Caleb Rickabaugh, Eric Olson, Hughes Christensen Certain formations create unique challenges for operators drilling directional applications with roller cone bits. In western Canada, for example, interbedded formations of hard sandstone, siltstone, shale and chert have frustrated operators using conventional tungsten carbide insert (TCI) bits to drill a directional wellbore. In addition to [...]
Improved design processes allow bits to fit specific applications, set new drilling records
Posted on 30 October 2009 in 2008, Drill Bits, July/August
By Jerry Greenberg, contributing editor Designing a drill bit with the correct configuration and hydraulic performance for a specific application has everything to do with a well’s success. A wrong bit for the application can result in low rate of penetration (ROP), inefficient hole cleaning and expensive wells that sometimes won’t reach the operator’s geological [...]
Innovative, application-specific drill bit designs prove value, help operators set drilling records
Posted on 12 March 2009 in 2009, Drill Bits, March/April
A well is successful as a result of a drill bit with the correct configuration and hydraulic performance for the particular application. Designing the wrong elements can lead to low penetration rates, inefficient hydraulics for hole cleaning, and wellbores that may not reach the operator’s objective…
