Background/unmet need

To reach many petroleum reserves, operators often drill through shale formations or other unpredictable or unstable media, which may cause wellbore collapse. Such events cost billions of dollars for the industry.

Invention Description

This software program provides guidelines for controlling wellbore failure through the adjustment of drilling fluid density, salinity, azimuth, and well declination. DRILLER includes additional input data such as thermal and chemical affects, thereby achieving greater results.

Benefits/Advantages

    Improved drilling operations and reduced risk

Features

    Includes all primary factors that effect wellbore stability in wells using water-based or oil-based drilling fluids, including affects of ion flow and temperature on pore pressure changesAccounts for any general 3-dimensional stress state, chemical affects arising from fluid-shale interactions and thermal stressesUser friendly visual displaysExecution speed suitable for onsite field-type applications

Market potential/applications

DRILLER is an application for drill operators of petroleum producing companies and would be utilized for most drilling activities. GRID Technology Transfer LLC is currently representing DRILLER in the commercialization effort.

Development Stage

Beta product/commercial prototype
