Abstract: A method for detecting the occurrence of an event at a well comprising: recording a first set of measurements collected from the well; processing the recorded measurements to provide a first set of data; calculating a first score based on the first set of processed data; recording a second set of measurements collected from the well; processing the second set of recorded measurements to provide a second set of data; calculating a second score based on the second set of processed data; wherein the first set of processed data and the second set of processed data is the number median of absolute difference from normal; combining the first score and the second score using a weighted average; and comparing the combined scores to a predetermined rule based on a specified time frame; and allowing an operator to adjust parameters of the well operation based on the score comparison.

Abstract: Systems and methods for treating wastewater with an oil-specific viscosifier composition and separating viscosified oil, undissolved solids and/or particulates, and/or other waste materials in such wastewater are provided. The methods further include: providing wastewater that includes oil; mixing the wastewater with an oil-specific viscosifier composition to form a viscosified oil; and separating at least a portion of the viscosified oil from the wastewater to provide treated water.

Abstract: Automated systems and methods for treating wastewater or effluent are provided.

Abstract: Apparatuses and methods measuring properties of drilling fluids in which the drilling fluid is contained in a structure, and a measuring device and a processor are used to measure the properties. The measuring device is immersed within the drilling fluid. The measuring device can comprise a shell defining a chamber, a weight adapted to cause the measuring device to sink through the drilling fluid, a transmitter and at least one sensor adapted to measure a property of the drilling fluid. The transmitter is adapted to transmit data representing the property to the processor.
