Swellable spacer fluids can be useful in subterranean operations for sealing an annular space in a well bore, such as the annular space between a tubular and the subterranean formation or between two concentric tubulars, or for forming a seal inside a well bore in the subterranean formation. One embodiment of such methods involves providing a swellable fluid, wherein the swellable fluid comprises: an aqueous fluid, a crosslinking agent, and at least a plurality of swellable particles; and placing the swellable fluid in a subterranean formation, and allowing the spacer fluid to form a semi-solid crosslinked gel structure in the subterranean formation.

Swellable spacer fluids and associated methods

A system for measuring one or more physical properties of cementitious material is operable to cure a slurry of cementitious material under desired conditions of temperature and pressure. Particularly, the system may be operable to cure the slurry under a temperature and pressure expected to be experienced downhole. The system may also be used to determine properties of the cured cementitious material, such as maximum yield strength and shear bond strength at the desired temperature and pressure. The desired conditions of temperature and pressure may be applied both during curing and testing of the cementitious material.

A method of servicing a wellbore in contact with a subterranean formation, comprising: placing a wellbore servicing fluid comprising a crosslinkable polymer system and a filler into a lost circulation zone within the wellbore. A method of blocking the flow of fluid through a lost circulation zone in a subterranean formation comprising placing a first composition comprising a packing agent into the lost circulation zone, placing a second composition comprising a crosslinkable polymer system and a filler into the lost circulation zone, and allowing the compositions to set into place.

A method of servicing a wellbore comprising preparing a liquid plug, allowing the liquid plug to polymerize into a highly deformable elastic plug, and placing the highly deformable elastic plug into a wellbore. A method of servicing a wellbore comprising preparing a liquid plug, allowing the liquid plug to polymerize into a highly deformable elastic plug, combining the highly deformable elastic plug with at least one conventional plug to form plug combination, and placing the plug combination into a wellbore. A method of servicing a wellbore comprising preparing a liquid plug, allowing the liquid plug to polymerize into a highly deformable elastic plug, placing the highly deformable elastic plug into a wellbore, and deforming the highly deformable elastic plug.

Method to control the physical interface between two or more fluids

A hydraulic control and actuation system for downhole tools. In a described embodiment, a hydraulic control and actuation system includes an internal chamber serving as a low pressure region and a well annulus serving as an energy source. A valve assembly provides selective fluid communication between alternating opposite sides of a piston and each of the energy source and low pressure region. Displacement of the piston operates a well tool. Operation of the valve assembly is controlled via telemetry between a remote location and an electronic circuit of the system.

A system and method to model and analyze the mixing energies of high-yielding non-Newtonian fluids to prevent chemical lost circulation is disclosed. Laboratory tests are performed under varying conditions from which data on the mixing energies needed to optimize the use of high-yielding non-Newtonian fluids to prevent lost circulation is obtained. This data is then applied to a non-linear mathematical modeling system that is capable of scaling the data to give a dimensionless value. This value can be combined with historic information to predict optimal flow rates and mixtures to prevent chemical lost circulation. This data may be verified by means of simulation, lab testing, or application to a full-size well.

An internally oriented perforating apparatus and associated method of perforating provide increased reliability in orienting perforating charges to shoot in desired directions in a well. In a described example, a perforating gun includes a tubular gun carrier, multiple perforating charges, multiple charge mounting structures and multiple rotating supports. The rotating supports are attached between the charge mounting structures, or at least between the perforating charges.
