Systems and Methods to Predict and Inhibit Broken-Out Drilling-Induced Fractures in Hydrocarbon Wells

摘要

Provided are embodiments that include the following: determining that a minimum circumferential hoop stress (σθθ^MIN) of a wellbore drilled into a subsurface formation is less than or equal to a tensile strength (T_o) of formation rock in the wellbore; determining that a lamination density (D_L) of the formation rock is greater than a threshold lamination density (D_Lthres); determining that a composition of the formation rock is a clay rich laminate; determining that a linear swelling ratio (LSR) of the formation rock is within a specified range; and in response to the determinations, operating the well to inhibit the occurrence of broken-out drilling-induced fractures (BODIFs).
