... in compartmentalized reservoirs. In such conditions, it seems reasonable to use extended horizontal wells as pilot holes, as it will allow to obtain information about the geological structure from a much larger area. In the case of horizontal pilot hole drilling through the reservoir rocks within the oil-saturated...
