Abstract: An orientation sub includes a pair of connectors that consists of a first connector and a second connector with the first connector. A center section joins the first connector to the second connector. The second connector connects the orientation sub to a tool. The center section has a predetermined geometric configuration with that self-orients the tool when the orientation sub and the tool are inserted into a well defined by casing.

Abstract: A bridge plug for deployment in a well defined by casing has a stackable tubular body having a front portion, a middle portion, a back portion, and an internal bore extending therethrough with the front portion having a first opening in fluid communication with the internal bore and the back portion having a second opening in fluid communication with the internal bore. The stackable tubular body has an outer configuration shaped to receive another adjacent bridge plug when the adjacent bridge plug is stacked within the well. The middle portion includes an expandable component that can frictionally engage the casing to hold the bridge plug in a fixed position within the well. The expandable component can be destroyed, at least partially, to facilitate movement of the bridge plug within the well while maintaining fluid communication between the first opening and the second opening.

Abstract: A method includes determining a stress variation of a geological formation disposed on a wellbore; determining a breakdown pressure of each perforation of a plurality of perforations along a length of the wellbore based on the stress variation; calculating a flow rate of a pumping operation of a hydraulic fracturing process based on the breakdown pressure of each perforation of the plurality of perforations; and hydraulically fracturing a geological formation disposed on the wellbore based on the flow rate.
