Benefits of technology

[0009]The present invention increases system effectiveness and reduces mechanical risk, thereby increasing system reliability while lowering cost. Operators need not be concerned about impacting the shifting ball into a seat at too high of a rate or pressure which may lead in some cases to a failure of the ball or sleeve.

Problems solved by technology

Embodiment Construction

[0029]When used with reference to the figures, unless otherwise specified, the terms “upwell,”“above,”“top,”“upper,”“downwell,”“below,”“bottom,”“lower,” and like terms are used relative to the direction of normal production through the tool and wellbore. Thus, normal production of hydrocarbons results in migration through the wellbore and production string from the downwell to upwell direction without regard to whether the tubing string is disposed in a vertical wellbore, a horizontal wellbore, or some combination of both. Similarly, during the fracing process, fracing fluids move from the surface in the downwell direction to the portion of the tubing string within the formation.

[0030]FIG. 1 depicts a valve seat assembly 22 in which the tool to be actuated is a ported sleeve. A tubing string section 26 provides a fluid communication path between the ported sleeve assembly 22 and other downhole tools or accessories.

[0031]The ported sleeve assembly 22 can transition between three stat...

Abstract

A valve seat assembly for actuating a connected downhole tool. The connected downhole tool may be mechanically connected, such as a sleeve positionable between flow ports through a housing, or hydraulically connected, such as through establishing a fluid communication path to the tool to cause actuation thereof. The valve seat assembly generally has a seating element with an having an inlet and an outlet; and a counting element configured to keep a tally of the number times a first pressure at the inlet exceeds a second pressure at the outlet by at least a pre-determined amount.
