Drilling
Operators aren’t rushing to drill, even as the closure of the Strait of Hormuz drives oil prices up.
This paper presents the first global application of autonomous drilling in deepwater and the journey to reach optimal drilling parameters, integrating proprietary tools from the project’s business partners.
This paper describes the evolution of the operator’s initial PWC (perforate, wash, and cement) abandonment projects performed in deepwater Brazil.

The wireline formation tester (WFT) is a well-developed technology used to collect representative downhole fluid samples. The authors introduce a simple but effective method for monitoring WFT sampling when targeting the low levels of contamination needed for asphaltene-onset-pressure analysis. -
This work focuses on the laboratory techniques for developing, assessing, and analyzing innovative water-based drilling fluids containing iron oxide (Fe2O3) and silica (SiO2) nanoparticles.

At certain conditions, the good performance of synthetic-based mud (SBM) will degrade, particularly because of the effect of chemical instability under high temperature. Silicon dioxide (SiO2) nanopowder (nanosilica) holds the potential for performance improvement.

Experience has revealed that frictional pressure loss in the wellbore hinders the full use of the entire length of the horizontal well. This paper presents a new approach to maximize the use of the full length of long horizontal drainholes.

This study compares the performance of openhole-packer completion systems with that of cemented-liner completion systems in the northern Montney gas resource play.
-
In horizontal and extended-reach wells in which long completions are run into highly deviated or lateral zones, large compression loads arise because of running friction.
-
The engineering and operational planning to ensure that no uncontrolled hydrocarbon releases occur during the execution of subsea big-bore gas wells are described.
-
Understanding drilling dynamics, the downhole shock and vibration that occur while drilling, is a crucial step to improving drilling efficiency and reducing nonproductive time (NPT).
-
In organic shales, hydraulic fracturing is important for optimizing the production of horizontal wells. For a standalone lateral, the propped surface should be maximized to increase production. In the case of a pad, well spacing is an additional factor.

With limited resources and lots of dedication, West Virginia University students wowed judges of the ATCE Drillbotics drilling automation challenge with the automated drilling device they built.
