Abstract: Fluid tests may be performed to determine suitability of an additive for a production enhancement treatment. In one aspect, a measuring device is used to determine a result of adding a sample of solid material to a test fluid that includes an additive. The result may include, for example, a change in surface tension, a change in contact angle, and/or another result. The measured result is used to determine the suitability of the additive for use in a stimulation treatment for a subterranean formation. For example, the additive may be determined suitable for use during a pad phase of a fracture treatment, during a proppant-laden phase of a fracture treatment, and/or for other phases and/or types of stimulation treatments.

Abstract: In one aspect the invention is a method of managing an entity. The method includes associating an identity of an entity to reputation data, associating a rule to the identity based on status data and the reputation data associated with the identity. The method also includes determining a response based on the rule associated with the identity.
