Many articles have been writing about this matter, some with high technical explanation other with complicated terminology; this time we like to simplify and explain it using simple terminology the complex behavior of influxes (gas kicks) in Oil Based Mud (OBM) and Water based mud (WBM). In the video below you can see the differences Continue reading
Introduction Why do we need to perform torque and drag analysis? Torque and drag removes superstition and reduces dependence on assumptions from well planning by taking into account all aspects of the plan from equipment specifications and formation properties. Changes made to specific components during planning is readily computed for the entire system. This allows Continue reading
A successful validation of Drillsoft® hydraulics software transient well model was carried during the drilling operation in deep-water well in West Africa. Using Pressure-While-Drilling (PWD – measurement of downhole annulus pressure and temperature) to compare the measured ECDs and static mud densities with hydraulic transient model predictions. This article present actual pressure and temperature data during Continue reading
Managed Pressure Drilling: Operations Safety Measures Question: How do you know is the managed pressure drilling Operation matrix is “safe”? RCD Limit: 450 psi LOT: 13 ppg Min Influx allowed while drilling: 2 Bls* Max Influx allowed while drilling: 5 Bls* * Data as per company’s polices Answer: Run IME and check safe influx values.
