Abstract: A technique facilitates reducing or eliminating the risk of premature actuation of a liner hanger system and/or premature release of a miming tool. According to an embodiment, the technique utilizes a running string for deploying a liner hanger assembly having a liner hanger which may be actuated at a desired location to suspend a liner/casing from a surrounding casing string. An anti-preset module may be used in cooperation with the liner hanger to prevent premature actuation of the liner hanger. By way of example, the anti-preset module may use pressure equalization between a region within the miming string and a region between the miming string and the liner hanger to prevent pressure imbalances which could actuate the liner hanger. Additionally, a locking mechanism, e.g. releasable lock dogs, may be used to temporarily lock the liner hanger against premature actuation.

Abstract: A technique facilitates simplified cementing operations in a borehole with fewer trips downhole. The technique utilizes a cementing system having a stage cementing collar in combination with a cup tool. According to an embodiment, the stage cementing collar may comprise a collar body, a no-go connected to the collar body, and a port closure sleeve which serves as a valve positioned to close/open flow ports extending laterally through the collar body. The cup tool may be conveyed downhole on, for example, jointed pipe or coiled tubing, for engagement with the port closure sleeve. The cup tool is used to shift the port closure sleeve between operational positions, e.g. from a port open to a port closed position.

Abstract: A downhole isolation tool including a sub, a sleeve disposed in the sub, and a ball seat mandrel coupled to the sleeve, the ball seat mandrel having at least two ball seats axially aligned with at least two throughbores disposed within the ball seat mandrel. A method of isolating a well, the method including running a downhole isolation system into a well, wherein the downhole isolation system includes a first downhole isolation tool, the first downhole isolation tool including a first sub, a first sleeve disposed in the sub, and a first ball seat mandrel coupled to the first sleeve, the first ball seat mandrel having at least two ball seats of a first size axially aligned with at least two throughbores disposed within the first ball seat mandrel, dropping at least two balls of a first size into the well, and seating the at least two balls of the first size in the at least two ball seats of the first ball seat mandrel.

Abstract: The present invention relates generally to a rotary handle. More particularly, the invention encompasses a deliberate action rotary handle. The invention further includes an extended drive-plate deliberate action rotary handle, such that to turn on a component, such as, a circuit breaker, requires a deliberate manual action by the user. If a deliberate action is not taken by a user but the handle is accidentally pushed then the handle does not engage with a drive shaft and the handle moves to an outer edge of a drive plate thus preventing the engagement of the handle with the other components to turn on the component.
