Abstract

The invention provides a system and computer program for identifying the depth of leaks in well casing strings after receiving temperature-depth data from a thermally conditioned well. Upon receiving the data, the system calculates moving average temperature gradients over a specified length of the casing. It then computes the mean and standard deviation of these gradients to determine a lower control limit (LCL) using a predefined formula. The system identifies leak depths by locating gradients below the LCL. The computer program generates control charts, visual alerts, and detailed reports to facilitate leak detection, offering a streamlined and effective approach to well integrity assessment.

Abstract

A computing system identifies a geographical region of interest. The computing system generates a background numerical weather prediction using a mesoscale numerical weather prediction model. The computing system identifies information associated with wind farms for inclusion in the geographical region of interest. For each wind farm, the computing system determines a wake effect of neighboring farms to the first wind farm by projecting wind deficits for the neighboring farms to generate a plurality of wake effects for the geographical region. The computing system generates an estimated power output for the wind farms in the geographical region of interest based on the plurality of wake effects.

Abstract

A method for predicting fluid flow fields in a subsurface reservoir or aquifer inputs training sets of geologically realistic models, fluid properties, and reservoir properties to a dynamic simulator to generate a set of labelled geologically realistic models. The labels relate to reservoir pressure and one or more of reservoir fluid saturation and reservoir fluid mass accumulation. The labelled geologically realistic models are then used to train a backpropagation-enabled process. The trained backpropagation-enabled process is then used to predict reservoir pressure and one or more of reservoir fluid saturation and reservoir fluid mass accumulation for a non-training model.

Abstract

A method for detecting leaks in a casing involves running a fiber-optic distributed temperature sensing cable into a well casing to obtain at least one trace in real time. The method includes thermally conditioning the well by inert gas injection and utilizing a trace to calculate moving average temperature gradients at predetermined intervals, determine the mean and standard deviation of these gradients, and establish a lower control limit based on the mean and standard deviation. By identifying any moving average temperature gradient below the lower control limit, the method enables the determination of the depth associated with leaks in the casing.
