Rotation is a legitimate way to overcome drag. There is a fixed amount of friction that needs to be overcome to move the string, in any direction. When tripping in, all friction acts in the axial direction, and generates drag. When rotating at a fixed depth, all friction acts in the radial direction, and generates …
ERA Software has a Predictive ROP Algorithm – it’s fast and easy to use and one more tool in the box for improving ROP and overall performance improvement. The concept is a simple one, we basically take the MSE Equation and re-arrange it to solve for ROP: Note that there’s a couple of new parameters …
The Time Plot Below, Shows The Sequence Of The Connection At This Depth: During connections, setting the slips under compression in high angle wells can lead to a bit / BHA components damage or drill pipe failure. The drill pipe must be set in slips with a tension very close to the Rotating Off Bottom …
It is possible for the bottom hole circulating temperature to be higher than bottom hole static temperature? This is contrary to popular belief that circulation cools down the well/BHA. The reason that the circulating temperature is higher is because the pressure drop along the drill string during circulation is dissipated as heat energy to increase …
Did you know that in a high angle well, poor hole cleaning results in lower ECD? This is contrary to the popular belief that ECD increases when hole cleaning is poor. The reason that ECD decreases with poor hole cleaning is that only cuttings suspended in the mud contributes to ECD while cuttings laying on …
In high angle or extended reach wells, Torque is generally not a good indicator of hole condition – in most cases torque friction factors actually REDUCE over the course of a long drilling section. In the example below, a 6000ft section of high angle 9⁷⁄₈” hole was drilled. Right after drilling out the previous casing …
K&M Technology’s Proprietary Software Platform ERA (Extended Reach Architecture) features a “steady state” circulating temperature model that is used to correct fluid density, downhole rheology, and metallurgical properties of tubulars to adjust for temperature effects. The temperature in the well is computed based on the heat transfer between formation, pipe and fluid in the annulus. …
K&M Technology’s Proprietary Software Platform ERA (Extended Reach Architecture) Sweeps and Tripping Circulation feature allows you to see the pressure (ECD) at any point in the wellbore while a sweep moves through the annulus.
K&M Technology’s Proprietary Software Platform ERA (Extended Reach Architecture) has a Built in Sensitivity Analysis feature. ERA allows the user to see results with sensitivity to practically any drilling, tripping or cementing parameter. You can choose which parameter to run sensitivity on or rely on ERA’s built in set of standard plots which is populated …
K&M Technology’s Proprietary Software Platform ERA (Extended Reach Architecture) Time Based Data feature (imports bulk time data from drilling recorders and filters out T&D measurements and other drilling parameters).
