ABSTRACT:
The present method of drilling, completing and fracturing enhances the production from any reservoir where artificial lift devices are required. However, this method is most suitable for a low pressure, partially depleted subterranean reservoir (50) where secondary recovery methods have proven unsuccessful, or where virgin drainage and pressure has been depleted. The method comprises drilling a substantially horizontal wellbore (20) which penetrates a subterranean reservoir (50) at a degree sufficient to provide drainage through the total vertical section of the reservoir. The horizontal wellbore (20) intersects a vertical wellbore (10) at the lowest vertical depth reached. Fracture stimulation may be applied from either the vertical wellbore, the horizontal wellbore, or both. Moreover, several horizontal well bores (20) can be drilled from a single surface (a) location to intersect other vertically drilled wells (10) or existing producing wells in a reservoir.
