INTEGRATED NUMERICAL SIMULATION OF FISHBONE WELL STIMULATION IN PETROLEUM RESERVOIRS

Unconventional oil reservoirs exhibit low permeability and porosity, requiring
stimulation techniques to ensure economically viable production rates. Alongside conven-
tional methods such as matrix acidizing and hydraulic fracturing, Fishbone drilling has
emerged as a promising alternative. In this work, the OpenFOAM solver upstreamFoam
is employed to evaluate the impact of Fishbone stimulation on oil production yield in a
reservoir-well system, in comparison with a conventional reservoir-well configuration with-
out Fishbone branches. A parametric sensitivity analysis is performed to assess the effect
of the total Fishbone length and inclination angle on the oil production gain.
