Abstract
A system for use in treating a wellbore may include a tubular string deployed in the wellbore; and at least one valve assembly connected to the tubular string, each valve assembly for establishing communication between the tubular string and a formation zone, the at least one valve assembly comprises a sleeve having at least one fluid port therein that expands in an axial direction when the valve assembly opens to form a flowpath between an interior of the tubular string and the formation zone.
Claims22
A system for use in treating a wellbore, the system comprising:
- a tubular string deployed in the wellbore and that extends in an axial direction along the wellbore;
- at least one valve assembly connected to the tubular string and configured to establish communication between an interior volume of the tubular string and a formation zone, wherein the at least one valve assembly comprises:
- a sleeve with at least one fluid port wherein the sleeve is configured to expand in both the axial and the radial directions when an inner sleeve of the valve assembly is in an open position and the sleeve is exposed to pressure;
- and
- wherein the at least one fluid port is configured to expand in the axial direction when the inner sleeve of the valve assembly is in an open position.
A system for use in treating a wellbore, comprising a casing deployed in the wellbore and fixed therein by cement;
- and
- a plurality of valve assemblies connected to the casing, each valve assembly for establishing fluid communication between the casing and a formation zone, the valve assembly comprising;
- a sleeve having fluid ports therein wherein each fluid port comprises an hourglass shaped slot, and wherein the sleeve expands in both an axial and a radial direction when an inner sleeve of the valve assembly is in an open position and the fluid ports expand in an axial direction from a flowpath between an interior of the casing and the well bore.
A method of treating a lateral wellbore through a formation, comprising:
- deploying a tubular string having at least one valve assembly connected thereto into the lateral wellbore;
- actuating an inner sleeve of the at least one valve assembly into an open configuration, thereby creating a flow path between an interior of the tubular string and the formation;
- delivering a treatment fluid through the opened valve assembly;
- expanding a sleeve of the at least one valve assembly in both an axial and a radial direction;
- and
- fracturing the formation along a plane that is substantially transverse to the lateral wellbore.
