Drilling
An earlier deal to double Israel’s gas exports to Egypt led to approval of Leviathan’s Phase 1B expansion by guaranteeing long-term cash flow to finance the project.
Rystad Energy expects the continent to account for the largest share of frontier and basin-opening wells in 2026 as operators pursue scale and untapped resources.
This paper presents a multifaceted approach leveraging precise rig control, physics models, and machine-learning techniques to deliver consistently high performance in a scalable manner for sliding.
-
The complete paper presents a solution that integrates a physics-based torque-and-drag (T&D) stiff/soft string model with a real-time drilling analytics system using a custom-built extract, transform, and load translator and digital-transformation applications to automate the T&D modeling work flow. -
The complete paper discusses a new performance-evaluation methodology that combines bottomhole assembly (BHA) modeling with field data.
-
The complete paper presents a methodology designed for optimally matching drill bits, mud motors, and bottomhole-assembly components for reduced failure risks and improved drilling performance.
-
This paper explores the nature of the vibrational dysfunction known as BHA chatter. A field-proven frequency-domain model illustrates the cause of the dysfunction, its rotary-speed dependence, and mitigation methods and results.

The London-based company is seeking to restructure more than $3 billion in debt as it struggles to find work for its offshore fleet.
-
Achieving and sustaining performance drilling’s intended benefits—improved drilling efficiency with minimal downhole tool failures and the associated reductions in project cycle time and operational costs—requires new protocols in drilling-system analysis.

A Canadian company reports that it has drilled and completed a historic horizontal well in Saskatchewan.
-
Through the end of October, 38 rigs have been retired this year. Predicting future rig attrition is not an exact science, but certain metrics help identify those rigs.
-
There is a growing interest in using nanocomposites to improve drilling-fluid rheology. In recent years, an additive derived from a sequence of graphene-based materials has been reported. The progress of these graphene derivatives has been used as a paradigm for water-based drilling fluids.
