This book covers research on horizontal well seepage, fracture optimization, and water control. It analyzes nonlinear seepage in low permeability reservoirs and proposes methods for tight reservoirs. Shear fractures' impact on permeability and stress sensitivity is studied. Oil recovery, waterflooding, and residual oil distribution are examined. Simulations on depletion mining, waterflood, and CO2 flooding are included. Key development parameters...
