Definitions
- This disclosure relates to a fracturing system and method for acquiring oil and gas.
- Multi-stage Tracking is a method that involves pumping large amounts of pressurized water or gel, a proppant and/or other chemicals into the wellbore to create discrete multiple fractures into the reservoir along the wellbore.
- proppant fracturing usually involves multiple steps and requires several tools in order to be performed successfully.
- Such practice that will allow even distribution of proppant between fractures highly depends on setting, plugs between the fracture stages or using frack balls of increasing sizes.
- plugs are either set after each fracture has been perforated and pumped, or frack balls are dropped from the surface to successively open fracturing valves placed along the well.
- frack balls are dropped from the surface to successively open fracturing valves placed along the well.
- balls of different diameters are dropped into the well corresponding to a specific fracturing valve's seat.
- the ball will no longer pass through due to a decrease in well diameter.
- tracking can take place.
- the plugs must be drilled out and the balls must be recovered.
- a delayed actuating system can comprise a base pipe comprising a first portion of an orifice, a sliding sleeve around the base pipe, the sliding sleeve comprising a second portion of said orifice, further said sliding sleeve maneuver able into a first position, wherein said first portion of said orifice rests at least partially over said second portion of said orifice, a second position, a distance away from said second position.
- the delayed actuating system can comprise a biasing device biasing the sliding sleeve toward the second position, and a destructible impedance device at least partially in side said orifice, the destructible impedance device preventing the sliding sleeve from leaving the first position.
- a method of delaying actuation comprising is disclosed.
- the method can comprise connecting a base pipe within a pipe string, the base pipe comprising a first portion of an orifice, applying a force on a sliding sleeve using a biasing device, the force configured to actuate the sliding sleeve from a first position to a second position, the sliding sleeve comprising a second portion of an orifice, the sliding sleeve positionable into said first position, wherein the second position of the orifice rests at least partially over the first portion of the orifice, said second portion, a distance away from the second position, and preventing the sliding sleeve from leaving the first position using a destructible impedance device.

While intact, bar 701 can prevent actuator 206 from releasing. As actuator 206 attempts to push or pull sliding sleeve 200 in one direction, it applies a tension force bar 701. Bar 701 can be held in place in a number of ways. In one embodiment, bar 701 can be connected to base pipe 100 and/or sliding sleeve 200 in a fixed manner. In another embodiment, the sheering force of sliding sleeve 200 and base pipe 100 can hold bar 700 into place. In another embodiment, bar 701 can fit into brackets attached to shding sleeve 200 and/or base pipe 100.
- impedance device can be destructible.
- a deshuctible impedance device is one that is designed to fail under the right conditions.
- One method of breaking the impedance devices is by pushing a corrosive material reactive with impedance device 206 through tracking port, deteriorating the impedance until actuator 206 can overcome its impedance.
- This method can work in embodiments wherein impedance device comprises a corrodible material (such as animal hair in the case of string 601). Corrosives material can be an chemical snch as hydrochloric acid. If impedance device comprises erodible material, then other methods can be used to break it.
- empedance device is made of thin steel or some other material, it can predictably fail after enough fluid passes around it, eroding it over time.
- Another method of breaking impedance device is by pushing a fluid comprising particulates snch as sand, glass or rocks through fracking port 102, in an embodiment wherein impedance device comprises an erodible material such as a soft rock, or sand that is mixed, formed and hardened with a weak epoxy.
- Another method of breaking the impedance devices is by pushing a large object such as a ball down the hole and through fracking port 102.
- Figure 8 illustrates fracturing valve 500 in production mode.
- fracking port 102 can close and production port 103 can open.
- track ball 501 can push stop balls 502 back into the inner end of first sleeve 202 which can further allow track ball 501 to slide through base pipe 101, to another fracturing valve 500.
- production port 103 is opened, extraction of oil and gas can start.
- production ports can have a check valve to allow fracking to continue downstream without pushing frack fluid through the production port.
