It’s widely known that the majority of stuck pipe incidents occur while pulling out of hole. If we can detect where an incident might occur – for example, in a 20,000-ft well – that could mean a radical reduction in nonproductive time (NPT) related to wellbore stability or drillstring integrity…

In planning for ultra-extended-reach (uER) wells, projected torque & drag (T&D) loads exceed the capabilities of existing high-strength drill pipe. As operators continue to evaluate uER well options, they have been forced to consider using non-steel drill pipe materials (such as aluminum, titanium, composite or other) for reduced surface loads…

It’s estimated that less than 1% of the oil and gas market uses aluminum drill pipe (Al DP). Although there are many claimed benefits – primarily its lighter weight vs steel – the higher costs involved have generally confined the pipe to niche applications…

In a down market, at least one sector of the oil and gas industry is holding steady – the well intervention business. Some service providers even anticipate an uptick in business that could sustain for the next two years…

As expandable technology matures, it has become a larger part of the wellbore construction toolbox. Operators no longer see expandables as problem-solving contingency tools, in part because of service companies’ aggressive development…

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…

This is the downturn everyone expected. They just didn’t expect it so soon. Anyone with a sense of history of the oil and gas business is wise to the reality that a ceaseless upward cycle just is not in the cards. The cards always come tumbling down…

The average age of the worldwide well servicing rig fleet is over 25 years old, and many of these rigs are much older. The idea of using 25- to 30-year-old equipment seems ludicrous in most industries, yet there are still more rigs working today over 25 years of age than there are under age 10…
