Patent attributes
Fracturing tools for use in oil and gas wells are disclosed. The fracturing tools have a run-in position and two operational positions. A sleeve disposed in the bore of the fracturing tool comprises a sleeve port alignable with a first port in the housing of the frac tool, i.e., the first operational position, during fracturing operations. A second port having a restriction member is disposed in the housing and is closed by the sleeve during fracturing operations. After fracturing operations are completed, a return member in the frac tool moves the sleeve from the first operational position to a second operational position for production operations. In this second operational position, the first port is closed and the sleeve port is aligned with the second port. Movement of the sleeve from the first operational position to the second operational position is performed without the need for an additional well intervention step.
