Drilling Three-Mile Laterals with Magnetic Reference Technique
This article discusses the challenges of wellbore positioning and anti-collision when drilling three-mile laterals in onshore US drilling operations.
Fluid Circulation Effects on Torque and Drag Results
Hydraulic effects on torque and drag modeling have been thoroughly studied, yet their interpretation causes misunderstandings. Historical models disregard circulation effects.
Casing Wear in the Culzean Field: A Technical Analysis
This paper presents measured vs. predicted wear for six wells in the high-pressure, high-temperature Culzean field, located in the central North Sea.
Modeling Axial Rotary Drilling Dynamics for Drilling Automation
Analysis of low-frequency axial drilling dynamics shows significant regional variation from block velocity input to surface weight on bit (SWOB) or differential pressure outputs.
Bayesian Approach for Automated Geosteering
This technical publication explores how a Bayesian approach can overcome noisy data and interpretation ambiguity in automated geosteering systems.
Sustainable Efforts in the Oil Industry
The oil industry is investing in sustainable efforts amid concerns about climate change, with major companies exploring renewable energy sources.
DYNAMICS VIBRATION PREDICTION AND COMPARISON WITH DOWNHOLE DATA MEASUREMENTS…
During drilling operations, high drillstring vibrations may originate from various sources, namely, the bit-rock interaction, drillstring-wellbore contacts, stick-slip phenomena, fluid-structure interaction, and mass unbalances. Excessive…
Dynamic Downhole Drilling Simulation
This paper simulates a dynamic downhole drilling phenomenon resulting in non-productive time and unnecessary cost, optimizing drilling technique and recognizing dysfunction.
Learning Curve Benefits Resulting From the Use of a Unique BHA Directional…
This paper presents a unique automated methodology for Post Analysis of BHA directional behavior. It is based on modern 3D analytical models, combining BHA, BIT and formation effects with highly flexible data management.
MITIGATING AND UNDERSTANDING STICK-SLIP IN UNCONVENTIONAL WELLS
Stick-slip is still present in most wells drilled today, especially in unconventional wells. Friction is an inevitable and important force along the long lateral section, but it contributes to many types of dysfunctions that lead to drilling…
