Innovations in MWD/LWD and drill pipe technologies address key operator concerns and needs, put previously impossible wells into reach

Posted on 12 March 2009 in 2009, Features, Innovating While Drilling, March/April

Operators ask for a lot in their logging-while-drilling (LWD) and measurement-while-drilling (MWD) tools. And why shouldn’t they, considering the sizable chunks these services can chew off of a budget?

Acoustic telemetry, with multiple nodes in drillstring, used to achieve distributed MWD

Posted on 12 March 2009 in 2009, Innovating While Drilling, March/April

Unattended acoustic telemetry in real-time drilling environments can now include multiple nodes in the drillstring. We utilize a primary tool near the drill bit that transmits telemetry and sensor/directional information with one or more acoustic transponding devices at other sites along the drillstring, these incorporating both the primary signal and additional information from their own local sensors…

Along-string pressure, temperature measurements hold revolutionary promise for downhole management

Posted on 12 March 2009 in 2009, Innovating While Drilling, March/April

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…

High-strength, thin-wall, all-steel drill pipe may provide solution for ultra-extended-reach wells

Posted on 12 March 2009 in 2009, Innovating While Drilling, March/April

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…

Lightweight, ultra-high-strength drill pipe may meet demands of ERD, critical deep drilling

Posted on 12 March 2009 in 2009, Innovating While Drilling, March/April

Current and future extended-reach drilling (ERD) and other critical projects exceed the capabilities of conventional steel S-135 drillstring assemblies…

Company taking aerospace alloys to oil/gas

Posted on 12 March 2009 in 2009, Innovating While Drilling, March/April

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…

Review & update: Expandable technologies gain traction through accumulated experience

Posted on 12 March 2009 in 2009, Completing the Well, March/April

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…

Innovative, application-specific drill bit designs prove value, help operators set drilling records

Posted on 12 March 2009 in 2009, Innovating While Drilling, 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…
