摘要： Systems and methods presented herein enable the automation of perforation gun deployment to a downhole location in a well at an oilfield. For example, at least one perforation gun may be deployed into the well with a conveyance line coupled to a head of a downhole tool string that includes the at least one perforation gun, and advanced with pump assistance from at least one pump unit at the oilfield. Deployment of the at least one perforation gun may be adjusted by a coordinated controller in an automated manner based at least in part on monitoring of a pump rate of the at least one pump unit and a tension at a head of the downhole tool string.
