Empirical Analysis of Lateral Spacing Uncertainty in North America Due to MWD…
Analyzes uncertainty in lateral spacing due to MWD survey errors in North America, considering the significant uncertainties in bottom hole locations from MWD instruments.
A Comparison of High-Resolution Trajectory Methods and Their Impact on…
Wellbore trajectories are a fundamental piece of data used for decisions throughout the oilfield. Trajectories are typically mapped through measurement-while-drilling (MWD) survey stations collected at 95ft intervals. Previous work suggests that…
Wellbore Placement Challenges and Solutions in the Barents Sea
Discusses challenges and solutions for accurate wellbore placement in the Barents Sea, emphasizing the importance of precise local magnetic field specification for reliable orientation in horizontal drilling, and the need for spatial models to…
Enhanced Wellbore Placement Accuracy Using Geomagnetic In-Field Referencing…
This paper discusses enhanced wellbore placement accuracy using geomagnetic in-field referencing and multi-station correction. IFR models are computed from high-resolution satellite and aeromagnetic measurements of the geomagnetic field. A new…
Economic Impact of Spacing Uncertainty in Long Laterals
This technical publication models the economic impact of spacing uncertainty in unconventional long laterals due to common survey practices.
Optimizing Lateral Well Spacing By Improving Directional Survey Accuracy
Optimizing lateral well spacing is a challenging problem that has significant economic consequences, field development requires spacing horizontal wellbores at an optimum distance.
IMPROVING DIRECTIONAL SURVEY ACCURACY THROUGH REAL-TIME OPERATING CENTERS
Web-based software was developed to provide rig site personnel with a simple interface to transfer survey data in real-time to survey analysts in a remote operations center.
Modeling Axial Oscillation Tools in Drilling Computations
Axial Oscillation Tools (AOT) can be used when drilling complex wells to introduce axial vibration to the drillstring and better transmit weight to the drill bit.
Axial Force Transfer of Buckled Drill Pipe
Technical publication about axial force transfer in deviated wells, focusing on the effect of drill pipe rotation on force transmission, even beyond buckling criteria.
