Enhancing the effects of a low-pressure zone surrounding a well bore via radial drilling by increasing the contact zone for resident microbial enhanced oil recovery

A method of increasing low pressure zones for microbial enhanced oil recovery comprising:

• 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.
