Geomechanical modeling helps to match the density of drilling mud

«Tatneft» has implemented the first full cycle geomechanical modeling software product in Russia.

The complex includes traditional 1D modeling tools, such as pore pressure forecast, calculation of the trajectory and stability of the wellbore. The software allows to determine the windows of the safe density of the drilling mud, to choose the intervals of the methods of intensification of the inflow. Specialists of the oil company, TatNIPIneft Institute (Bugulma) and Innopolis worked on the complex. This is reported by the portal “Production Management”.

“Geomechanical tools make it possible to increase the efficiency of drilling wells, for example, to choose the density of drilling mud,” said one of the authors of the development, an employee of TatNIPIneft.

When drilling, the software is used to prepare the drilling program before the start of work and when drilling online. There will be an opportunity to adjust during the work. The software tools are implemented in 3D format. It has full functionality for spatial modeling, including calculation of the stress-strain state, accounting for fracturing and fault tectonics of oil and gas deposits.

The complex also includes 4D modeling tools that allow you to work considering dynamics and time changes. A separate module of the program for processing the results of geomechanical studies has also been developed. It automates file processing using machine vision.
