Drillingtechnology Stories

Correctly evaluating the risk of BHA, casing and/or completion strings getting stuck or locked-up when RIH can ultimately provide a template for ultimate reduction of no...

Indeed, some simultaneous torque-drag-buckling calculations are presented and allow to properly take into account the additional contact force generated in a post-buckli...

Friday night lights... tailgating Saturdays... and of course, armchair quarterbacking Sundays. It's the most wonderful time of the year! Now, imagine if your favorite fo...

As spring approaches in the United States, many of us drilling in Oklahoma and Texas welcome the nicer temperatures but must also remain weather-aware with an expectatio...

The use of time-domain modeling to jointly characterize the behavior of downhole axial and surface oscillation tools introduced in this work allows a better understandin...

When we talk about Actively C.A.R.E.™ (controlling and removing exposures), that can often be interpreted as only focusing on exposures that can harm people on the job...

After two years of testing the recovery control system internally, there were no undetected stalls, no false detections, and no unplanned trips due to motor stall, displ...

We know that energy exposures provide a significant amount of threat to a worker on a drilling rig. We also know it is important to have strong processes in place to hel...

This paper will be presented by E.S. Kolstad at the 2007 SPE/IADC Drilling Conference held in Amsterdam, The Netherlands, 20-22 February 2007. Read and download the tech...

A multi-stage penalized procedure is developed that optimizes this alignment map to minimize a misfit function, while taking the prior knowledge into consideration. Read...

Analysis of low frequency axial drilling dynamics from block velocity input to surface weight on bit (SWOB) or differential pressure outputs, shows significant regional...

This work is novel because it combines a ground based, near-well, magnetic measurement with an airborne derived IFR-1 model. This allows for a greater reduction in posit...

The Coaching Guide originated in 2018 as part of a campaign to equip our Drilling Superintendents and HSE staff with additional tools and skills for coaching employees i...

This paper should provide help to engineers who seek to improve the accuracy of casing wear prediction and hence improve casing wear management. It presents a new way of...

With directional drilling in today's market, well placement is of ever-increasing importance in the process of successfully drilling a well. Well placement by Measuremen...

The dynamics is then calculated by applying a time-integration scheme. The dynamic model is applied to a real case of a quasi-vertical well with field measurements of do...

Directional surveys acquired by Measurement While Drilling (MWD) are subject to many errors that are not easily recognized by traditional Quality Control (QC) procedures...

Thunderstorms are electronically monitored on the platform for lightning strikes, because offshore drilling rig masts and crane booms are normally the tallest structure...

REMOVE UNCERTAINTY WITH DATA AS YOU DRILL Drilling practices alone are not enough to accurately deliver a high quality wellbore, as success is equally dependent on the a...

This paper describes some of the challenges to understanding and ultimately automating drilling processes using models. Examples of models used to solve industry problem...
