Abstract
Official abstract text for this publication.
Methods and systems for controlling drilling operations include using a statistical model to identify at least two controllable drilling parameters having significant correlation to one or more drilling performance measurements. The methods and systems further generate operational recommendations for at least two controllable drilling parameters based at least in part on the statistical model. The operational recommendations are selected to optimize one or more drilling performance measurements.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of drilling a wellbore, the method comprising: receiving surface measurement data regarding drilling parameters characterizing ongoing wellbore drilling operations, wherein at least one of the drilling parameters is controllable; determining rate of penetration (ROP) and mechanical specific energy (MSE) utilizing the received surface measurement data; utilizing a computer processor to calculate (i) a drilling performance measurement embodied in an objective function comprising a relationship between the determined ROP and the determined MSE, wherein the objective function comprises at least one of; OBJ ( MS E , R O P ) = δ + Δ R O P / R O P o δ + Δ M S E / M S E o . a OBJ ( MS E , R O P ) = δ + Δ R O P / R O P δ + Δ M S E
