Application of Forced Vibration Modeling in Drilling Operations
This technical publication discusses the application of a forced vibration modeling approach to quantify the role of downhole vibrations and excitation tools in drilling operations.
Fifty Ways to Leave Your Wellbore: An Honest Look at the Causes and Costs of…
Unplanned sidetracks are low-frequency, high-cost events that negatively impact the economics of oil field development. This study analyzes data from high-volume drilling operations to establish a meaningful baseline.
Complex Liner Deployment
Innovative engineering workflow used to ensure the safe deployment of deep production liners on long step-out wells of a deep offshore development field.
Typelog Alignment for Automated Geosteering with Multi-Stage Penalized…
Quantitative typelog alignment method using a Bayesian approach, uses drilling data to better estimate 3D geological formations around the drilling path.
USING HYBRID PROPULSION AUTONOMOUS MARINE VEHICLES TO BETTER CHARACTERIZE…
Presents a study conducted to develop and validate new capabilities for offshore geomagnetic surveying that employs the autonomous marine vehicle (AMV) to map the crustal magnetic field and monitor disturbance fields surrounding offshore drill…
Motor Bend Affects Stick-Slip Vibrations: Modeling and Case Study
This technical publication models the relationship of motor bend and stick-slip vibrations during unconventional well drilling. A case study is included.
FOOTHILLS DRILLING PERFORMANCE IMPROVEMENT – A NEW TRANSVERSAL APPROACH
Total E&P initiated a drilling campaign in 2018 near the foothills of Bolivia where wells can be extremely challenging and lengthy to drill. These wells mandate exhaustive planning due to the geological complexity and abrasive environment prone to…
RSS and Motor Directional Analysis: Modelling the Effect of Local Doglegs on…
This paper aims to present a methodology that allows the anticipation of problems such as mechanically stuck pipe or lock up situations when running in hole casing or completion strings.
Axial and Surface Oscillation Tools: Tool Face Control
Two solutions used to overcome friction forces are axial oscillation tools (AOT) and surface oscillation tools (SOT), especially in unconventional well trajectories.
Assessing Stabilizer Design for Drillstring Vibration
A technical publication assessing the effect of stabilizer design on drillstring vibrations through detailed dynamics modeling. Testing stabilizers can be costly.
