This disclosure provides a pre-mixed lost circulation treatment that can be pre-mixed ahead of time at a plant and delivered to a drilling site in one or more transport containers because the pre-mixture having a shelf life of at least one month and possibly longer. Because the components of the lost circulation treatment are mixed at a controlled mix site, the consistency of the lost circulation treatment is improved and can be better maintained from one lost circulation treatment to another. Further, one or more of the components of the pre-mixed treatment can be placed in a portable tote container that can be quickly and easily transported to the drilling site upon demand, or the tote can be delivered to the drilling site before a lost circulation zone is actually encountered.

Mixing process and delivery of lost circulation slurries

Generally, assessing the properties of a plug comprising wellbore strengthening materials may enable the design of more efficient wellbore strengthening additives and fluids because the properties of the plug may translate to the near wellbore strengthening effect of the wellbore strengthening materials of the plug. Assessing such properties may involve applying a differential pressure to a plug formed in a passageway of a tool comprising at least one sensor proximal to the passageway plug, and then measuring at least one attribute selected from the group consisting of a normal plug pressure, a normal plug displacement, and any combination thereof with the at least one sensor.

Methods relating to designing wellbore strengthening fluids

A method of treating a formation that includes injecting gelling components curable by a moisture cure into a selected region of the formation; and controlling the onset of curing of the gelling components by contacting the gelling components with a drying agent is disclosed.

Methods of delaying the curing of moisture sensitive curable elastomers

A method of treating a well the method including the steps of: (A) forming a fluid including: (i) a shear-thinning aqueous liquid phase; and (ii) an inorganic setting material; wherein the fluid is shear-thinning, pumpable, and settable; and (B) introducing the fluid into the well.

Viscous settable fluid for lost circulation in subterranean formations

A method of treating a formation that includes exposing a region of the formation occupied by a hydrolysable gel to a hydrolyzing agent; and allowing sufficient time for the hydrolyzing agent to hydrolyze the gel. Various methods may also include the use of a swelling agent to allow for expansion of the gel.

Degradable non-aqueous gel systems

A lost circulation material and method for well treatment employing the material that is effective at sealing or plugging fractured zones and has utility over a wide range of temperatures, including high temperatures. The lost circulation material includes particulate material to quickly de-fluidize the fluid formulation, fibrous material to suspend particles in the slurrified form of the composition and increase the shear strength of the resultant seal, and non-Portland cement material for increasing the compressive strength.
