Abstract: The effect of drilling fluids on particular subterranean environments can be analyzed to improve the formation of drilling fluids and additives such as lost circulation materials. A plug can be generated by a particle plugging apparatus by injecting lost circulation material into the particle plugging apparatus. A set of tests to be performed on the plug can be identified. The set of tests can include at least one physical test and at least one electronic test. A test schedule indicating the order in which each test of the set of tests is to be performed can be defined. The set of tests can be executed to generate a testing output. The testing output can be used to generate a three-dimensional network model of the plug.

Abstract: Described herein are methods and apparatus for testing bond strength of a chemical-sealant, lost circulation material to a subterranean sample. An apparatus can include a body defining walls of a chamber to receive a subterranean core sample from a wellbore, the body being sized to receive a chemical-sealant lost-circulation material (CS-LCM) to an area of the chamber between the core sample and the body, and a removable insert mateable to the body, the insert defining a base of the chamber, where the test apparatus is positionable to transfer a force to the core sample to decouple the core sample from the CS-LCM such that a shear bond strength of the CS-LCM to the core sample is determinable based on a maximum amount of force used to decouple the core sample from the CS-LCM.

Abstract: Methods for using cement compositions in subterranean formations are provided. In some embodiments, the methods comprise introducing a first treatment fluid comprising a first base fluid and a metal oxide into a wellbore penetrating at least a portion of a subterranean formation; introducing a spacer fluid into the wellbore that separates the first treatment fluid from at least a second treatment fluid; introducing the second treatment fluid into the wellbore, wherein the second treatment fluid comprises a second base fluid and a soluble salt; allowing the first treatment fluid to contact the second treatment fluid to form a cement mixture; and allowing the cement mixture to at least partially set.
