RTD is a software designed for drilling and completion engineers to achieve a safe drilling and wellbore integrity during drilling processes. RTD can be applied during pre, real-time, and post-drilling processes, respectively. 3D in-situ stresses and geomechanical parameters can be calculated or interpreted via MEM module, which can be built up based on seismic, core, leak-off, Mini-Frac tests, mudlog and mono/dipole logging data. During real-time drilling, WITSML data are utilized and drilling risks such as stuck-pipe, differential sticking, cavings-in, kick, breakout, losses and pack-off can be predicted and diagnosed . Wellbore stability can also be evaluated and forecast subject to the real & planned well trajectory. Surface design parameters can be adjusted based on the real-time drilling info accordingly.
The RTD Features includes :
-
Reading and displaying real-time drilling data such as well trajectory and WITSML data for more than 20 wells simultaneously.
-
Developing 3D MEM from various of data sources.
-
Allowing imported or interpreted in-situ stresses and geomechanics data.
-
Predicting wellbore stability at any given depths and providing safe windows
-
Design and display 3D well trajectory
-
Allowing surface pressure and pumping rate design and adjustment for stability and risk-free purpose.
-
Forecasting formation pressures and wellbore stability problems ahead of drilling bit.
-
Allowing MPD and UBD designs
-
The mud osmosis effects is considered to handle the impacts of swelling clay on wellbore stability.
-
Casing depth design can be performed based on mud density design.
-
Surface mud density, pumping rates, and pressure can be adjusted for the target and current drilled wells.
-
MEM model is developed based on off-set wells and also from the drilled section of the current well.
-
Temperature effects include heat conduction & convection
-
Predicting downhole pressure profile
-
Calculation of rock mechanical parameters
-
Sensitivity analysis on key parameters
