Abstract: The disclosure presents a technique for determining how downhole material will be distributed among two or more active perforation clusters in a hydraulic fracturing well system. The determination can be conducted during the execution of a treatment stage allowing modifications prior to completion of the treatment stage. The technique utilizes a three-step process where a first step can determine a predictive model of the wellbore, such as subterranean formation properties, wellbore properties, and target goal of the treatment stage. A second step can calibrate for unknown parameters, such as downhole HF fluid pressure at the active perforation clusters and downhole HF fluid flow rate at the perforation clusters. A third step can predict how downhole material will be distributed to the active perforation clusters and fracture clusters. The prediction result can be utilized to modify a pumping plan of the treatment stage to better achieve the targeted goal.

Abstract: A dual-factor PIN based authentication system and method uses a cryptogram provided by a contactless card associated with the client in association with a PIN stored by the contactless card to authenticate the client. In some embodiments, cryptogram authentication may be preconditioned upon a PIN match determination by the contactless card. In other embodiments, the cryptogram may be formed at least in part using the personal identification number (PIN) stored on the contactless card encoded using a dynamic key stored by the contactless card and uniquely associated with the client. Authentication may be achieved by comparing the cryptogram formed using the PIN against an expected cryptogram generated an expected PIN and an expected dynamic key.
