Abstract:
The present invention relates to a system and method of increasing low pressure zones for microbial enhanced oil recovery through radially drilled narrow, high surface area bore holes around a well bore. A drill string is inserted into the well bore and is thereafter directed horizontally and perpendicularly from the well bore by a tool at the end of the radial drill to create the narrow, high surface area bore holes. These bore holes extend through surface materials including pipes, casings, cement, rock material and the like. The drill is then rotated a distance about the well bore. The process may then be repeated to create bore sets positioned below or above one another relative to a pay zone. The process lowers the pressure gradient along a skin around the well bore and a larger surface area extending away from the well bore to create a larger oil drainage and microbial interaction area. The invention further includes injecting a nutrient package formulated to activate resident microbes such that the microbial morphology is physically changed which in turn increases the relative permeability of the oil, water, and rock interaction thereby enhancing overall oil production and recovery.

Claim (Index 1):
A method of increasing low pressure zones for microbial enhanced oil recovery comprising:\n drilling a plurality of narrow, high surface area bore holes radially and perpendicularly from a vertical well bore by a radial drill; inserting a one inch diameter drill string of the radial drill in to the well bore; directing the drill string horizontally by a tool at the end of the radial drill to drill a first bore hole through surface materials; retracting the drill string in to the well bore; rotating the drill around the well bore a predetermined distance from the first bore hole of the plurality of narrow, high surface area bore holes; repeating the process to create at least a second, third, and fourth bore hole of the plurality of narrow, high surface area bore holes creating a first set of bore holes; injecting a tested and determined nutrient formulation designed to activate resident microbes into the well bore such that the nutrient formulation and reservoir fluids flow toward a producer well; lowering the pressure at a skin area a distance from the well bore and over a larger area created by the set of bore holes such that large low pressure microbial saturation zones are created; and wherein lowering the pressure creates a large area of positive flow or oil toward the well bore due to the interaction with activated microbes such that oil well production and recovery are increased.
