Hydraulic fracturing system, apparatus, and method
An apparatus according to which a subterranean formation in which a wellbore extends is hydraulically fractured, the apparatus comprising first and second manifolds, the first manifold including first and second flow lines adapted to be in fluid communication with first and second pumps, respectively, the first pump being adapted to pressurize fluid received from the first flow line, and the second pump being adapted to pressurize fluid received from the second flow line, and the second manifold including a third flow line adapted to convey pressurized fluid from the first and second pumps to the wellbore to hydraulically fracture the subterranean formation in which the wellbore extends. The apparatus is adapted to be connected to another apparatus used to hydraulically fracture the subterranean formation in which the wellbore extends by moving one, or both, of the first and second flow lines relative to the third flow line.
1. An apparatus used to hydraulically fracture a subterranean formation in which a wellbore extends, the apparatus comprising:
a first platform supporting:
first and second flow lines adapted to be in fluid communication with first and second pumps, respectively, the first pump being adapted to pressurize fluid received from the first flow line, and the second pump being adapted to pressurize fluid received from the second flow line, and
a third flow line adapted to convey pressurized fluid from the first and second pumps toward the wellbore to hydraulically fracture the subterranean formation in which the wellbore extends; and
a second platform, distinct from the first platform, supporting a fourth flow line in fluid communication with the third flow line, the fourth flow line adapted to convey the pressurized fluid from the third flow line toward the wellbore.
2. The apparatus of claim 1 ,
wherein the apparatus is adapted to be connected to another apparatus used to hydraulically fracture the subterranean formation in which the wellbore extends; and
wherein one, or both, of the first and second flow lines are movable relative to the third flow line to permit the connection of the apparatus to the another apparatus.
3. The apparatus of claim 1 , wherein:
the first platform and the second platform comprise separate skids, each skid having first and second rails; and
first and second trucks to which the first and second flow lines, respectively, are connected;
wherein one, or both, of the first and second trucks are movable along the first and second rails, respectively, to thereby permit the movement of one, or both, of the first and second flow lines relative to the third flow line.
4. The apparatus of claim 1 , further comprising:
a fluid block connected to the third flow line and adapted to receive the pressurized fluid from the first and second pumps; and
first and second valves connected to the fluid block and adapted to selectively prevent communication of the pressurized fluid from the first and second pumps, respectively, to the fourth fluid line.
5. The apparatus of claim 4 , wherein the second platform is supported in an elevated position above the first platform so that the third flow line is vertically offset from the fourth flow line.
6. The apparatus of claim 1 , wherein the first, second, and third flow lines define first, second, and third, inner diameters, the third inner diameter being greater than the first and second inner diameters.
7. The apparatus of claim 1 , further comprising a zipper manifold adapted to convey the pressurized fluid from the fourth flow line to the wellbore to hydraulically fracture the subterranean formation in which the wellbore extends.
