Techniques for plugging at least one zone of a hydrocarbon well are disclosed herein. The techniques include methods for deploying a wellbore dart configured for plugging the at least one zone of the hydrocarbon well, receiving, by a first node, location information indicating a first location of the wellbore dart, receiving, by a second node, location information indicating a second location of the wellbore dart, and detecting, an arrival of the wellbore dart at an intended location for the dart to plug the zone of the hydrocarbon well. In some aspects, the method further includes sending a command to a firing module of the wellbore dart, the command effective to cause the wellbore dart to plug the zone of the hydrocarbon well. Systems and computer-readable media are also provided.

Automated isolation system

Aspects of the subject technology relate to systems and methods for pumping multiple wellbores from a common pumping source. A fluid pump of known operating pump capacity can be selected. The pump can be fluidly connected to a common pumping source that is fluidly connected with each of a plurality of cased wellbores in a subterranean formation for providing pumped fracturing fluid to each of the wellbores. Each of the plurality of wellbores can have at least one perforation through a casing of the wellbore with a known rate range within which fracturing fluid is required to be provided to the perforation to successfully fracture the subterranean formation outside the perforation, through the perforation. Further, the wellbores can be configured so that the common pumping source provides fracturing fluid to each of the perforations within the known rate range of the respective perforation to successfully fracture the subterranean formation.

Wellbore hydraulic fracturing through a common pumping source

Aspects of the subject technology relate to systems and methods for pumping a wellbore with a pump operating in a damage avoidance mode during a hydraulic fracturing job. A fluid pump of known operating pump capacity measurable in barrels per minute is selected. The pump is fluidly connected with each of a cased wellbore in a subterranean formation for providing fracturing fluid to the wellbore. The wellbore has at least one perforation through a casing of the wellbore that has a known rate range within which fracturing fluid is required to successfully fracture the subterranean formation outside the perforation through the perforation. The pump is configured to provide fracturing fluid to each perforation within the known rate range of the respective perforation to successfully fracture the subterranean formation outside of the perforation while operating the pump in a damage avoidance mode.

Wellbore hydraulic fracturing through a pump operating in a damage avoidance mode

A plurality of clean fluid pumps fluidically coupled to a common line, the plurality of clean fluid pumps configured to pump a clean fluid. A plurality of individual lines extending from the common line to a plurality of wellbores, each wellbore of the plurality of wellbores having at least one individual line of the plurality of lines solely fluidically coupled thereto. A plurality of dirty fluid pumps, each wellbore of the plurality of wellbores having at least one of the dirty pumps solely fluidically coupled thereto, the fluidic coupling being downstream from the common line. A flow control device, such as a choke, installed in at least one of the individual lines, the installation being downstream from the common line and upstream from the point of the fluidic coupling of the at least one dirty fluid pump to the corresponding wellbore.

Simultaneous multiple well stimulation

Aspects of the subject technology relate to systems and methods for injecting down-hole tools into a fracturing line. A fracturing system may include a fracturing line of a respective wellbore and a launcher operationally coupled to the fracturing line though a respective supply line at a pressure lower than a pressure of the fracturing line. The fracturing system may further include a magazine containing a plurality of down-hole tools that is operationally coupled to the launcher for sending a down-hole tool of the plurality of down-hole tools to the launcher. The fracturing system may also include a launching chamber operationally coupled to the respective supply line for receiving the down-hole tool and having a pressure automatically adjustable to substantially equal the pressure of the fracturing line after the launching chamber is sealed from the respective supply line for disposing the down-hole tool into the fracturing line.

Multiple down-hole tool injection system and method

Aspects of the subject technology relate to systems and methods for pumping multiple wellbores to form and stabilize fractures during a fracturing job. A fluid pump of known operating pump capacity measurable in barrels per minute is selected. The pump is fluidly connected with each of a plurality of cased wellbores in a subterranean formation for providing fracturing fluid to each of the wellbores. The plurality of wellbores each have at least one perforation through a casing of the wellbore that has a known rate range within which fracturing fluid is required to successfully fracture the subterranean formation outside the perforation through the perforation. The pump is configured to provide fracturing fluid to each of the perforations within the known rate range of the respective perforation to successfully fracture the subterranean formation outside of the perforation.
