IADC operations push forward with focus on improving drilling efficiency worldwide

Posted on 30 October 2009 in 2008, Drilling It Safely, IADC: Global Leadership, Global Challenges, Innovating While Drilling, Onshore Advances, September/October, The Offshore Frontier

It’s been another exciting and challenging year as IADC strives to fulfill the needs of an intensely demanding and always-evolving industry. In government affairs, for example, we continue to provide critical input on the EU’s Working Time Directive and critical court appeals that will impact day-to-day drilling operations. Our accreditation & certification department is further […]

MPD planning: How much is enough?

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

By Paul Spriggs, Philip J Frink, Blade Energy Partners This article addresses the key drivers and risks associated with the use of applied backpressure managed pressure drilling. One of the two key issues that must be understood early on is whether the well can be drilled statically overbalanced or if it needs to be drilled […]

Defining drillstring specifications to maximize safety, performance in sour service environments

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

By Anne Sevignon and William Gamisans, VAM Drilling The evolution of drilling programs has driven the industry to develop more suitable solutions adapted to extreme and aggressive environments such as sour service. High-strength drill pipe is necessary to achieve deeper drilling objectives, even if the sulfide stress cracking susceptibility is an acknowledged concern starting with […]

Service company geomechanics group: Knowledge integration is our objective

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

In today’s high-cost drilling environment, the lack of integration of valuable pore pressure or other reservoir information can cost a company millions of dollars, said Colin Sayers, scientific advisor for Schlumberger’s geomechanics group. He cited an example of one oil company where the geophysics department never told the drilling department about a small fault above […]

Working the pore pressure puzzle: Different Languages, same goal

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

Pore pressure knowledge is critical when designing a well. It’s unlikely that anyone in this industry would argue with that. Pore pressure drives the casing design, which drives the well plan, including hole sizes and mud weight. An inaccurate pore pressure model could even lead to a well control event, causing financial losses or, worse, […]

Case study: new concentric expandable reamer tool used in Gulf of Mexico

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

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

Posted on 30 October 2009 in 2008, Drilling Rigs & Automation, Innovating While Drilling, Onshore Advances, September/October

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 […]
