The workshop in brief:
Session 1: The Kirkuk tertiary reservoir has fractured rock matrix with porous blocks. Oil production occurs from matrix and fractures, creating water-filled voids at oil/water contact (OWC) and gas-filled voids at gas-oil contact (GOC). Fractures allow faster oil rise, resulting in submerged blocks that can only contribute through slow imbibition, the only way to recover oil trapped under water. Temperature affects imbibition recovery with a wettability index of 0.24 indicating weak water-wet characteristics. “All faces open” boundary conditions yield efficient and fast imbibition oil recovery. This session provides an overview of experimental work, imbibition cell design, and study results.
Session 2: Water flooding is crucial for maintaining reservoir pressure and improving oil recovery in fractured carbonate reservoirs, which hold the majority of the world’s oil reserves. Challenges such as fractured and oil-wet conditions hinder oil recovery. Research focuses on altering wettability through chemical methods like surfactants and temperature-induced changes. A suggested study is modeling spontaneous imbibition in Kirkuk tertiary reservoir cores using finite-difference implicit scheme to match numerical results with lab data and evaluate key variables like relative permeability, viscosities, and saturations, as well as assess capillary pressure sensitivity on imbibition. Objectives are to show what happens actually in field. The study case is Kirkuk oil fields.
