A method and apparatus are disclosed for a mixing system with a recirculation pump and a sensor configured to measure a property of a fluid discharged from the recirculation pump, wherein the sensor may transmit the property to a control system to allow an operator to adjust the mixing system in response to changes in the measurement signal.

A settable composition may be designed to thicken at substantially the same time downhole and/or set at substantially the same time downhole independent of when the settable composition was introduced into the wellbore by varying the concentration of set retarders and/or set accelerators during placement of settable compositions. For example, a method may include introducing a settable composition into a wellbore, the settable composition having an initial portion with a first concentration of a set-time additive, a middle portion with a second concentration of a set-time additive, and a final portion with a third concentration of a set-time additive; choosing the first and the third concentrations of the set-time additive so that the initial portion has a longer set-time than the final portion; and thickening the settable, wherein the initial and final portions thicken to exceed a consistency of about 70 Bc within about 3 hours of each other.

Settable compositions with variable set times

Disclosed herein are methods and systems for the transportation and delivery of set-delayed cement compositions to a well site. A method of cementing may comprise preparing a set-delayed cement composition. The method further may comprise storing the set-delayed cement composition. The method further may comprise transporting the set-delayed cement composition to a well site in a containment vessel. The method further may comprise discharging the set-delayed cement composition from the containment vessel and into a wellbore.

An apparatus for rotating a threaded tightening device includes a guide and an anvil utilized to impact a lug on the threaded tightening device to rotate the tightening device onto or off of a threaded member. The guide has a frame with a support sleeve attached thereto. A reciprocating device is received in and is supported by the support sleeve. The anvil is attached to the reciprocating device. When the reciprocating device is received in and is supported by the support sleeve, actuation of the reciprocating device will cause the anvil to repeatedly impact a lug to rotate the threaded tightening device in the desired direction.
