Drilling Fluid That Fracks While Drilling And Can Be Used In Well Completion

摘要

A method of fracturing a subterranean formation while drilling, applying a new combination of completion techniques. When combined to work simultaneously together, these techniques have synergistic amplified benefits, dynamically opening fissures deep into the production zone. The saturated saltwater phase of the drilling fluid dehydrates all the clays and shale that are drilled through, by osmosis-opening up or enlarging production channels or paths while the relaxed filtrate penetrates further into the wall of the well bore through the naturally occurring fissures or channels in the formation. The saturated salt water fluid with a relaxed filtrate combines with a (0.5-5% by volume) variety of acids (encapsulated by natural oils or polymers) to acid etch or scour the clay or shale walls leaving an acid etch matrix of channeling for later hydrocarbon production.

主权项

1) A drilling fluid method that opens fractures and completes a well comprising the steps of:
applying a salt saturated or near salt saturated drilling fluid with water phase to dehydrate shale formations through osmosis; enlarging a crevice or fracture in hydrocarbon producing formations; and applying HCL to acid etch matrix shale, enlarging a crevice or fracture in hydrocarbon producing formations, applying “gravel packing” of proppants into the producing zone with a saturated salt fluid with an acid resistant polymer to hold open the newly enlarged fracture which would swell and begin to narrow when exposed to the less than saturated salt fluid flow of ground water during production of hydrocarbons.
