Sohail Waziri

Reservoir Simulation Engineer

[email protected]

Sohail Waziri is a Reservoir Simulation Engineer with ResFrac, responsible for programming the reservoir simulator of ResFrac.

Prior to joining ResFrac, Sohail earned a Bachelor’s degree in Petroleum and Natural Gas Engineering, with a double major in Chemical Engineering, from METU in Ankara, Turkey. He then earned a Master’s degree in Petroleum Engineering and a Ph.D. in Energy Science & Engineering from Stanford, where his research focused on developing a robust, fully implicit nonlinear solver for condensing geothermal systems that converges for arbitrarily large time-step sizes. He also completed internships with Chevron and TotalEnergies, focusing on the simulation of coupled flow and geomechanics in subsurface CO₂ systems and developing multi-phase reservoir initialization algorithms.

Outside of engineering, Sohail enjoys family walks, gym workouts, and weekend online gaming with friends and family.

Targeting the reserves between clusters: modeling strategic refracs and infills in ResFrac

Older, wide-spacing Delaware Basin wells can leave high-pressure rock stranded between fractures. Devon used ResFrac to design liner refracs whose peak rates came in within 1% of forecast, and to show why an offset infill beats a refrac at tight cluster spacing.

Automatic Report Generation in ResFracPro

This month’s release has a feature that I am particularly excited about – automatic report generation. The reports are generated automatically when a simulation finishes. Also, reports can be generated on-demand for simulations that have already been completed. The reports are highly customizable, allowing the user to generate different line plots, 3D visualizations, preview plots, and tabular data. The user can provide a template PPT, so that the report is made with their preferred PPT style.

Introducing ResFrac’s New Multisector Capability

This month’s ResFrac release has a ton of new capabilities. The most important is called ‘multisector’ – the ability to split different sections of the well across different computers. This capability provides a computationally efficient and practical way to run larger models and handle complex scenarios. Hats off to Danial Zeinabady and Michael Nole, who have been the main developers on this project. Beyond them, it’s been a big team effort, pulling in folks from cloud, simulator, and user-success. First, let’s review – what is sector modeling? Why do we need a ‘multi’ version of it?
