Abstract
This specification discloses a method of producing hydrocarbons from an unconsolidated hydrocarbon-bearing formation that is penetrated by a well that has an irregular wall adjacent the formation. Granular particles that are water-wet are injected down the well to fill the irregularities in the wall and a packer that has lateral passageways therethrough is set against the well wall. Pressure is applied via the packer to the formation in an amount no greater than the overburden pressure on the formation and hydrocarbons are produced from the formation via the lateral passageways of the packer into the well.
