Enhanced deep micro-fracturing tool using laser beams and acoustic waves

Abstract

A well system includes a wellbore extending from a wellhead and penetrating a producible reservoir and a downhole assembly extendable into the wellbore and including a laser component operable to emit a laser beam into the producible reservoir to induce a first plurality of micro-fractures extending radially outward from the wellbore. The downhole assembly includes a stimulation tool that includes an acoustic component including one or more acoustic generators operable to generate and propagate acoustic waves into the producible reservoir and thereby induce a second plurality of micro-fractures extending radially outward from the wellbore, and one or more acoustic receivers operable to detect and receive reflected acoustic waves returned back from the producible reservoir. The downhole assembly includes a fluid sampling component operable to extract fluid samples from the wellbore at locations radially adjacent the producible reservoir wherein data related to the reflected acoustic waves and the fluid samples is analyzed to characterize the first and second pluralities of micro-fractures.
