Perforation Cluster Design Method and System Based on a Hybrid Model to Predict Proppant Distribution
14 Apr 22
A method for determining the distribution of a proppant and associated slurry exiting perforations made in a casing, which is placed in a well, includes receiving settling data describing the proppant settling in the casing; receiving a slip parameter describing a casing velocity of the proppant relative to a perforation velocity of the proppant; calculating with a computing device, based on a constant proppant concentration model, (1) initial flow rates Q′(i) of the proppant through the perforations and (2) initial flow rates Q′case(i) of the proppant through the casing, wherein i is the number of perforations; and calculating with the computing device, based on (1) a variable proppant concentration model, (2) the settling data, (3) the slip parameter, (4) the initial flow rates Q′(i) of the proppant through the perforations, and (5) the initial flow rates Q′case(i) of the proppant through the casing, normalized flow rates Q′s(i) of the proppant through the perforations.

Addressable switch assembly for wellbore systems and method
22 Mar 22
A method for controlling a target switch assembly in a chain of switch assemblies includes distributing the chain of switch assemblies in a wellbore; placing a controller at a head of the wellbore; making a first decision, at the controller, to actuate a corresponding detonator of the target switch assembly; transmitting, from the controller to the target switch assembly, a fire command to activate the corresponding detonator; and making a second decision, locally, at the target switch assembly, to activate the detonator, after the fire command from the controller is received.
