OPTIMAL BOTTOM HOLE ASSEMBLY CONFIGURATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240044238 titled 'OPTIMAL BOTTOM HOLE ASSEMBLY CONFIGURATION

Simplified Explanation

The abstract of this patent application describes a method for designing a bottom hole assembly (BHA) using numerical optimization. The method involves applying a BHA design criterion using a numerical optimization algorithm to identify a set of BHA designs from a larger pool of possible designs. Multiple objective functions are evaluated for each design in the set, taking into account modeling constraints. A pareto-front of the solution space of the objective functions is identified using the optimization algorithm. A data point is selected from the pareto-front using a cost function, and a BHA design is selected from the set of designs using the selected data point. Finally, a BHA is built using the selected design to be deployed downhole in a wellbore.

Original Abstract Submitted

a method of defining a bha design includes performing a numerical optimization process, which includes applying a bottom hole assembly (bha) design criterion using a numerical optimization algorithm to identify a set of bha designs selected from a plurality of possible bha designs, evaluating multiple objective functions for each bha design of the set of bha designs based at least in part on a modeling constraint, and identifying a pareto-front of a solution space of the multiple objective functions using the numerical optimization algorithm. the method also includes selecting a data point from the pareto-front using a cost function, selecting a bha design from the set of bha designs using the selected data point, and building a bha using the selected bha design to be deployed downhole in a wellbore.
