Top drives have transformed drilling: Now, new design targets ultra-deep, ERD

Posted on 30 October 2009 in 2008, Innovating While Drilling, Onshore Advances, September/October, The Efficient Rig

By David Reid, Larry Wells and Jeremy Ogg, National Oilwell Varco In 1982, a radically new drilling system appeared in the oil patch, one that would ultimately allow tremendous advances in the oil and gas industry’s well construction capabilities. The advent of the original Top Drive System (TDS) foreshadowed the development of reservoirs that were […]

Geothermal drilling market heats up

Posted on 30 October 2009 in 2008, Global and Regional Markets, Innovating While Drilling, Onshore Advances, September/October

by Linda Hsieh, Assistant Managing Editor As oil prices reach unheard-of highs in the $140/bbl range, energy sources that have historically been considered too expensive to produce economically are getting new leases on life. Many such energy sources, like wind and solar, tend to reside far outside the realm of the oil and gas drilling […]

Geothermal holds potential for new energy – and for new drilling

Posted on 30 October 2009 in 2008, Global and Regional Markets, Innovating While Drilling, July/August, Onshore Advances

By Linda Hsieh, assistant managing editor Like many renewable energy sources, geothermal carries substantial potential for powering the world in an environmentally friendly way. However, also like many renewable energy sources, geothermal remains unable to evolve into a fully viable alternative to oil or natural gas. The late 1970s and early ’80s saw rapid growth […]

Tough directional TCIs deliver longer runs with higher ROP in Canadian build sections

Posted on 30 October 2009 in 2008, Innovating While Drilling, 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, Innovating While Drilling, 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 […]

Casing Drilling improves mature field production, eliminates fluid losses, directionally drills well

Posted on 30 October 2009 in 2008, Innovating While Drilling, July/August

By Eric Moellendick, TESCO Corp CASING DRILLING has been used in numerous difficult wells and to drill through troublesome well sections that would not have been possible with conventional drilling techniques. The process eliminates tripping of the drill string and requires only a Range II rig with a single mast. In addition, by reducing or […]

Seismic-while-drilling: Where is it heading?

Posted on 30 October 2009 in 2008, Innovating While Drilling, July/August

The concept of seismic-while-drilling (SWD) promises so much, yet still the industry has realized so little of that promise. Drilling Contractor spoke with Robert Radtke, president of Technology International, about where SWD is at, and where it might be headed. Technology International has been working on a joint project with the US Department of Energy […]
