Abstract
Abstract A vertical cased well penetrates two or more hydrocarbon bearing formations. A deviated well includes a horizontal drain hole extending a substantial distance into at least one of the formations. A production string is cemented in the horizontal drain hole and is cut off inside the vertical cased well. Perforations through the vertical cased well communicate the well with some or all of the formations. A production assembly in the vertical cased well includes a series of external casing packers isolating the hydrocarbon bearing formations. Wire wrapped port collars between the external casing packers controls flow into the production assembly and upwardly through the well. A resin coated sand may be plated in the annulus between the production assembly and the vertical casing to control the production of formation solids. The external casing packers straddling the entry of the horizontal drain hole into the vertical well may be provided with a bypass to allow the resin coated sand to overflow into the annulus above the production assembly.
