In order to improve the development of fields at a later stage, this article considered use water-gas repression together with dissolved gas energy. The theoretical basis study is based on application method physical modeling oil displacement by water. As result, it was found that waterflooding would be more effective when such an activity carried out in early stages development. Waterflooding ...

Counter-current imbibition in one dimension is analyzed, in which a wetting phase (water) displaces a non-wetting phase against gravity. An approximate analytical approach is used to derive an expression for the saturation profile in the case where the mobility of the displaced phase at the inlet is finite. This approach is applicable to waterflooding in hydrocarbon reservoirs, flow in geotherm...

Waterflooding adalah salah satu metode pemulihan sekunder yang bertujuan untuk mempertahakan tekanan reservoir. Volume air injeksi disesuaikan agar tidak terjadi penurunan oil recovery. Tujuan dari penelitian ini mengoptimalkan nilai Injection dan Recovery Factor (RF) dengan menggunakan Artificial Neural Network (ANN). Parameter digunakan porositas, permeabilitas horizontal, vertikal, saturasi ...

This work focuses on evaluating the effect of steam quality upgrading and recovering extra-heavy crude oil in presence absence two nanofluids. The nanofluids AlNi1 AlNi1Pd1 consist 500 mg·L?1 alumina doped with 1.0% mass fraction Ni (AlNi1) Pd (AlNi1Pd1), respectively, 1000 tween 80 surfactant. Displacement tests are done different stages, including (i) basic characterization, (ii) waterfloodin...

Generally, long-term waterflooding development often leads to the change of reservoir pore and clay mineral composition, which results in permeability wettability. In order explore relationship between core micropore structure water cut, based on physical simulation experiments fractal theory, we proposed a evolutionary model describe evolution characteristics microstructure driving reservoirs....

Introcution: Water-flooding is an effective way to develop the extra-low permeability oil reservoirs and water-flooding induced fracture (WIF) can improve waterflooding efficiency. However, geomechanical properties of rocks may alter due water-rock interactions, which usually increases heterogeneity reservoir affects WIF propagation. Methods: In this study, a method calculate propagation length...
