Abstract: Systems and techniques may be used for identifying geology, state of stress, or heat in place for a horizontal well. An example technique may include generating a 3D geologic model or a 3D temperature model of a horizontal well, receiving an indication of an orientation of a stress field in the horizontal well, and optionally drilling the horizontal well using the 3D geologic model, the 3D temperature model, or the indication of the orientation of the stress field. The example technique may include iteratively updating the 3D geologic model or the 3D temperature model of the horizontal well, for example based on in-well data.

Abstract: The present invention relates to systems and methods for developing and characterizing geothermal well systems. Data collected from a survey area is used to generate a 3D geologic model and a temperature distribution model of a subsurface region in the survey area. Using the 3D geologic model and the temperature distribution model, a vertical observation well is drilled to a specified depth, facilitating further collection of data from the survey area and improvement of the 3D geologic model and the temperature distribution model.
