摘要： An optimal perforating gun method for accurate perforation in a deviated/horizontal wellbore is disclosed. The method includes a gun string assembly (GSA) deployed in a wellbore with shaped charges arranged in rows in a cluster and a total number of the shaped charges is equal to a total number of the rows. A total number of charges for each cluster in a stage is selected with the best statistical probability for a desired number of perforations in the cluster. The number of charges and the number of rows per each cluster in a stage is optimized such that there is a maximum probability of perforating into a low compression region in an upward and downward direction.

摘要： A shaped charge that includes a case, a liner positioned within the case, and an explosive filled within the case. The liner is shaped with a subtended angle ranging from 100° to 120° about an apex, a radius, and an aspect ratio such that a jet formed with the explosive creates an entrance hole in a well casing. The jet creates a perforation tunnel in a hydrocarbon formation, wherein a diameter of the jet, a diameter of the entrance hole diameter, and a width and length of the perforation tunnel are substantially constant and unaffected with changes in design and environmental factors such as a thickness and composition of the well casing, position of the charge in the perforating gun, position of the perforating gun in the well casing, a water gap in the wellbore casing, and type of the hydrocarbon formation.

摘要： A sleeve actuation method for actuating sleeves in a reverse direction. The method includes a use of stored energy created by injecting into a connected region of a well such that the stored energy is used to actuate a tool installed in a wellbore casing that is either heel ward or uphole of the connected region. The tool actuated in a direction from toe end to heel end while the tool reconfigures to create a seat for seating plugging elements.
