System and method for fracturing of oil and gas wells
View Patent ↗A system and method for fracturing a well, wherein the system can comprise a base pipe comprising an insert port capable of housing a stop ball partially within the chamber of it, and a sliding sleeve. The sliding sleeve can comprise a first sleeve with an in inner surface. That inner surface can comprise a void. The first sleeve can be maneuverable into two positions. In the first position, the void can rest on a surface of the base pipe not comprising an insert port. Such positioning can prevent a stop ball from exiting the chamber of the base pipe. In the second position, the void can rest over an insert port. Such positioning can allow the stop ball to the chamber of said the base pipe and to enter the void.
1. A well fracturing system, comprising
a base pipe comprising
a fracturing port first portion and
an insert port capable of housing a stop ball, said stop ball partially within the chamber of said base pipe;
a sliding sleeve comprising
a first sleeve, said first sleeve comprising an inner surface, said inner surface comprising a void said first sleeve maneuverable into
a first position, wherein said void rests on a surface of said base pipe not comprising said insert port, preventing said stop ball from exiting the chamber of said base pipe; and
a second position, wherein said void rests over said insert port, said stop ball capable of exiting the chamber of said base pipe to enter said void;
a second sleeve;
a fracturing port second portion; and
one or more curved sheets connecting said first sleeve to said second sleeve, wherein the space between said one or more curved sheets defines said fracturing port second portion.
2. The well fracturing system of claim 1 wherein said base pipe further comprises a production port.
3. The well fracturing system of claim 2 , wherein said sliding sleeve, while in
said first position, said second sleeve blocks said production port; and
said second position, said second sleeve does not block said production port.
4. The well fracturing system of claim 1 , wherein said sliding sleeve, while in
said first position, said fracturing port first portion aligns with said fracturing port second portion; and
said second position, said fracturing port first portion does not align with said fracturing port second portion.
5. A well fracturing system, comprising
a base pipe comprising an insert port capable of housing a stop ball, said stop ball partially within the chamber of said base pipe;
a sliding sleeve comprising a first sleeve, said first sleeve comprising an inner surface said inner surface comprising a void, said first sleeve maneuverable into
a first position, wherein said void rests on a surface of said base pipe not comprising said insert port, preventing said stop ball from exiting the chamber of said base pipe; and
a second position, wherein said void rests over said insert port, said stop ball capable of exiting the chamber of said base pipe to enter said void;
an impedance device that impedes a biasing device from moving from a first position to a second position, wherein said impedance device is a string, the first end of said string connected to said base pipe, the second end of said string connected to said sliding sleeve, said string within a fracturing port first portion and a fracturing port second portion.
