... and perpendicular to the minimum horizontal stress. There are two distinct directions the wellbore can be drilled to enhance fracturing operations. If the horizontal well is drilled in the direction of the least horizontal stress, several vertical fractures may be spaced along its axis wherever perforations...

... fracture intercepting a horizontal well. Microfractures are usually performed on vertical wells to determine the minimum horizontal stress while minifractures are performed to determine leakoff coefficient. Because a vertical well is in the plane of a vertical fracture, determination of horizontal stress...
