Title (EN) MICROBIAL ENHANCED OIL RECOVERY IN WELL BORE VIA RADIAL DRILLING TO CREATE A LOW-PRESSURE ZONE
(FR) RÉCUPÉRATION AUGMENTÉE PAR VOIE MICROBIENNE DE PÉTROLE DANS UN PUITS DE FORAGE PAR FORAGE RADIAL POUR CRÉER UNE ZONE BASSE PRESSION
Abstract:
(EN) A system for increasing low pressure zones for microbial enhanced oil recovery through radially drilled narrow, high surface area bore holes around a well bore is provided. A drill string is inserted into and directed horizontally and perpendicularly from the well bore by a tool at the end of the radial drill to create bore holes which extend through surface materials. The drill is then rotated a distance about the well bore and process repeated to create bore hole sets. 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 which in turn increases the relative permeability of the oil, water, and rock interaction thereby enhancing overall oil production and recovery.
(FR) L'invention concerne un système pour augmenter des zones à basse pression pour une récupération augmentée par voie microbienne de pétrole par l'intermédiaire de trous de forage étroits, à surface élevée et forés radialement autour d'un puits de forage. Un train de tiges de forage y est introduit et dirigé horizontalement et perpendiculairement depuis le puits de forage par un outil au niveau de l'extrémité du foret radial pour créer des trous de forage qui s'étendent à travers les matériaux de surface. Le foret est ensuite mis en rotation à une certaine distance autour du trou de forage et le procédé est répété pour créer des ensembles de trous de forage. Le procédé abaisse le gradient de pression le long d'une peau autour du puits de forage et une zone de surface plus grande s'étendant à partir du trou de forage pour créer une zone d'interaction microbienne et de drainage de pétrole plus grande. L'invention comprend en outre l'injection d'un ensemble de nutriments formulé pour activer des microbes résidents qui, à leur tour, augmentent la perméabilité relative de l'interaction entre le pétrole, l'eau et la roche, améliorant ainsi la production et la récupération globales de pétrole.
