MANIFOLD AND SYSTEM FOR SERVICING MULTIPLE WELLS
First Claim
1. A manifold for delivering a fluid for selectively servicing two or more wells comprising:
- a manifold body having a live bore formed therethrough, the live bore having a live bore cross-sectional area;
an inlet fluidly connected to the live bore for receiving the fluid therein;
two or more distributors, each distributor being fluidly connected to the live bore, each distributor having two or more outlets fluid connected to one well of the two or more wells for delivery of fluids thereto, each outlet having an outlet bore with an outlet cross-sectional area; and
a valve positioned in each outlet bore of the two or more outlets for selectively isolating the fluid from one or more of the two or more wells,wherein the total outlet cross-sectional area for each of the two or more distributors is greater than the live bore cross-sectional area for reducing the velocity of the fluid in the two or more outlets.

Abstract
A manifold for distribution of well servicing fluids, such as fracturing fluids, to a plurality of wells. The manifold has a single bore through which the fluid flows and a plurality of outlets which are connected to the bore. Two or more of the outlets deliver the fluid to each wellhead. Valves are positioned in each of the outlets so that each of the wellheads can be independently isolated from the fluids for selecting which of the wells will be serviced at any given time. A total cross-sectional area of the outlets feeding each of the wells is greater than the cross-sectional area of the bore which results in a velocity reduction in the outlets which reduces erosion in the manifold and the downstream components Systems are described using prior art manifolds or manifolds according to embodiments of the invention for use specifically with fracturing fluids containing proppant. Proppant can be delivered to the fracturing fluid through the manifold, directly to the wellhead or both, to reduce erosion. Use of a manifold according to embodiments of the invention, in combination with the systems described, are particularly useful for reducing erosion with proppant-laden fracturing fluids.

12. A system for servicing two or more wells accessing a formation, the wells having wellheads attached thereto, the system comprising:
-
a manifold having a bore formed therethrough for receiving a fluid; an inlet fluidly connected to the bore for delivering the fluid to the bore; two or more outlets fluidly connected to the bore, at least one outlet fluidly connected to one of the two or more wells; and valves operatively connected between the bore and each of the one or more wells for isolating the fluid from one or more of the two or more wells, a source of the fluid, fluidly connected to the inlet; and a fluid connection for fluidly connecting between the at least one outlet with a wellhead of one of the two or more wells, wherein when the fluid is pumped from the fluid source to the manifold, the fluid flows unimpeded through the bore of the manifold for delivery to the two or more outlets, and when the valves are selectively actuated to an open position, the fluid flowing through the manifold is delivered to the one or more wells fluidly connected thereto; and when the valves are selectively actuated to a closed position, the one or more wells fluidly connected thereto are isolated from the fluid flowing through the manifold. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A method for replacing or repairing a valve in a manifold for selectively accessing two or more wells, the manifold having two or more distribution flow blocks, each distribution flow block fluidly connected to a main manifold bore and having two or more outlets fluidly connected to one well of the two or more wells for delivery of fluids thereto, each outlet having an outlet bore and a valve removeably secured thereto, comprising:
-
discontinue flow of fluid to the manifold bore; disconnect removeable connectors between the outlet and the valve; reconnect a new or repaired valve to the outlet; and reestablish the flow of fluid to the manifold bore.
