Title:
SYSTEMS AND METHODS FOR WELLBORE DRILLING UTILIZING A THERMOCHEMICAL SULFATE REDUCTION (TSR) PROXY
Document Type and Number:
WIPO Patent Application WO/2024/044962
Kind Code:
A1
Abstract:
This disclosure relates to systems for wellbore drilling and methods for preparing wellbore drilling fluid. The system can include a drilling fluid tank that holds wellbore drilling fluid for introduction into a wellbore, an additive distribution component fluidly coupled to the drilling fluid tank that holds a first additive, and a computing device communicatively coupled to the additive distribution component. The methods can include a computing device performing at least the following: receiving drilling parameters that identify wellbore drilling conditions of a wellbore drilling system, calculating a thermochemical sulfate reduction (TSR) proxy value of the wellbore. In response to determining that a predicted hydrogen sulfide concentration meets a predetermined threshold, the computing device can determine a first quantity of a first additive to be added to the wellbore drilling fluid and combine the first quantity of the first additive with the wellbore drilling fluid.
