“…We suggest the morphological evolution of the colloform bands is a consequence of increasing crystal mush thickness with progressive differentiation. with examples ranging from CO 2 , water and hydrocarbon migration within sediments (Tissot & Welte, 1984;MacMinn et al, 2010;Minescu et al, 2010) to extraction of partial melt from the mantle (McKenzie, 1984;Daines & Kohlstedt, 1994;Lundstrom et al, 1995;Kelemen et al, 1997;Dijkstra et al, 2003;Katz et al, 2006). When the infiltrating fluid is out of thermal or compositional equilibrium with the solid matrix (Jupp & Woods, 2003), it may react with its surroundings, potentially resulting in local solid dissolution and precipitation of new phases (Ortoleva et al, 1987a;1987b;Chadam and Ortoleva, 1990;Aharonov et al, 1997;Maisse & Pousin, 1997;Kang et al, 2003).…”

“…The connection angle of the interface with the solid surface is called the contact angle. It is defined as the plane angle of the dihedral angle between the plane tangent to the solid surface and the plane tangent to the fluid-fluid interface taken at a three-phase contact point, measured in the reference phase [8].…”

Defining the transition zone in clastic oil formations with mixed or water-preferential wettability is useful in estimating the initial oil resource, locating production and injection wells, choosing drilling intervals, predicting water intrusion into production wells, and modeling the reservoir for simulation purposes. The purpose of this article is to define the initial distribution of water in oil reservoirs and especially the knowledge of the transition zone, presenting theoretical concepts and practical methods for planning the necessary experiments and interpreting the data collected to define this part of the oil structure. The article presents the theoretical elements of the methods of obtaining and using capillary pressure curves, data on interfacial tension and contact angle. The dynamics of the saturation state during oil reservoir formation and the most optimal method for determining fluid contacts and free water levels are also described.

Minescu et al (2010) analyzes the mechanism and influencing factors involved in tertiary migration and introduces two production projects in Romania to prove the effectiveness of tertiary migration. Jacota (2014) discusses tertiary migration from the perspective of gravity differentiation and studies the parameters that mainly affect tertiary migration and combines with actual production cases.…”

Worldwide, for older fields that are in the late stages of production period, production wells that lose production value due to high water cut are usually shut down. In this situation, the remaining oil in the reservoir will be re-enriched under the influence of gravity differentiation and capillary forces. Production practices find when the production well is closed for a long time and then opened for restarting production, the water cut drops dramatically and the output rise sharply. In order to anticipate the effects of enrichment of remaining oil in the reservoir, this paper analyzes 10 influencing factors respectively. Secondly, change of water cut before and after shut-in is used as the evaluation index of residual oil enrichment effect. Numerical simulation method is used to simulate the influence of different factors on the effect of external migrations of remaining oil at different levels. Grey correlation analysis is utilized to rank the correlation of 10 factors on residual oil enrichment and then we can get the main controlling factors affecting residual oil enrichment. Finally, the response surface analysis method is used to establish a 5-factor 3-level model, and the corresponding prediction results are obtained through numerical simulation experiments. The main control factors are fitted to obtain the prediction formula of the remaining oil enrichment effect. As a result, we can use the prediction formula to forecast the enrichment effect of remaining oil under different reservoir parameters.
