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...

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...

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...

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...

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

The drilling and completion of oil and gas wells is a collaborative business, involving employees from many contractors working together. Well construction generates man...

One of the largest and longest operating onshore drilling and technology companies in the world, known for our signature. FlexRig® fleet, unmatched efficiency gains, and...

In the future, by demonstrating improved results over these baseline values, new technologies and drilling practices can better estimate the value provided to a drilling...

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...

Once the tasks of laying down casing and drill pipe were completed, the derrick was then lowered and replaced. The crew was cleared to resume drilling ahead. "Yeah...

A "trip" is the process of pulling drillpipe from the wellbore or running the pipe back to the bottom of the wellbore. The manual work performed during a trip...

64% reduction in the average torque standard deviation, indicating a smaller severity of torque swings Intermediate Section BHA Count 66% reduction in total intermediate...

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...

This modeling led to an optimum drill string design associating the steerable mud motor assembly, aluminum drill pipe, axial oscillation tool and steel drill pipe. The n...

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...

Viterbi is an established algorithm with many applications, but the splitting of stratigraphic mappings into a Bayesian state space and application of Viterbi is novel a...

The drilling industry faces challenges when it comes to implementing physics-based decisions in real-time, resulting in missed opportunities to improve drilling performa...

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...

Building upon the decision-making foundation, the next level of automation executes the steering decisions from the bit guidance system automatically. Read out the full...

Today, Drillers and Drilling Engineers are faced with significant challenges in effectively managing drilling parameters and mitigating risks associated with drilling dy...
