Drillingtechnology Stories

At H&P we dedicate the month of April to actively promoting vehicle safety in all forms. Our goal is to increase awareness of key topics like distracted driving, fatigue...

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...

These error sources can be reduced significantly by using a local geomagnetic In-Field Referencing (IFR) model and by subsequently applying multistation analysis (MSA) c...

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...

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

This study demonstrates that the procedure reduces the horizontal wellbore position uncertainty by 46% for the study area and more generally from 15 to 50 percent when c...

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

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...

They are then integrated in the torsional equation of motion of the stick-slip model. A case study is carried out to show the consistency between the simulated results a...

Imagine a loved one is going to work in an industry that has been know historically to be dangerous, like mining, forestry, law enforcement, or commercial fishing. What...

These analyses can constitute guidelines about stabilizer design to minimize vibrations. The novelty of this work is to introduce the geometry details of the stabilizers...

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...

Positional uncertainty can be modelled by 3-D EOUs at each survey point in the well path, representing a statistical distribution of where the actual survey may exist. E...

In addition, these results show the significance of string friction along the drill pipe. Next, the use of a downhole instrumented sub, along with wire drillpipe technol...

Already, the methodology has solved challenging directional performances issues, generating significant savings and optimizing the learning curve process. The model is a...

The oil and gas industry is witnessing a significant transformation with the advent of drilling rig automation. Traditional drilling operations are being upgraded with a...

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...

The hybrid AMV offers distinct advantages for geomagnetic data collection in offshore environments. The low cost compared to a seaborne or airborne vehicle allows AMVs t...

WHAT COULD 2-4 ADDITIONAL WELLS PER YEAR MEAN TO YOUR BOTTOM LINE? Contact us for more information on how our FlexRig® Fleet can help you achieve better drilling outcome...

An advanced Archimedes method with all fluid circulation effect has been developed. By tackling the problem of circulating fluid in the drill string using two different...
