A set of sixty four Mercury Injection Capillary Pressure curves from a Middle East tight carbonate reservoir were modelled with Thomeer hyperboles and grouped using K-medoids clustering.

Capillary pressure (P c) is the difference in pressure measured across the interface in the capillary (P c = P nw - P w). This pressure results from the contrast in pressure gradients caused by the different densities of the nonwetting ( ρ nw ) and wetting ( ρ w ) phases (right).

The MICP study demonstrates that the pore volume of the micropores (~25% of pore space) is volumetrically significant. Using Thomeer type curve analysis to fit the MICP data of our very large MICP data set, the pore systems’ volumes and entry pressures are quantified. capillary pressure model was derived theoretically. It was found that the universal capillary pressure model could be reduced to the frequently-used Brooks-Corey capillary pressure model and the Li-Horne imbibition model when the fractal dimension of the porous media takes a limiting value. The primary motivation for my work is to “close the loop” on relating mercury injection capillary pressure data and the simplified “bundle of tubes” permeability power law model by Brook and Corey, and is extended to incorporate the permeability model proposed by Huet-Blsingame [3] using the theory of Purcell [4] and Burdine [5], combined with the function fitting parameters of Brooks DOI: 10.2118/105139-MS Corpus ID: 140667487.

Thomeer capillary pressure model

The above equation gives the mapping between the elevation and the capillary pressure. The capillary pressure is proportional to the elevation above the free water level and the constant of proportionality is the product of the density difference and the acceleration due to gravity. A Capillary Pressure Function for Interpretation of Core-Scale Thomeer (1983), as well as Polynomial, Sigmoidal, Exponential (e.g., such as poor matches of threshold pressure and irreducible/residual fluid saturation, as well as inability to model a sharp capillary transition. For reservoir rock/fluid In this paper, we developed a novel methodology, based on Thomeer formalism and optimization techniques, for capillary pressure estimation using “standard” log data. With this methodology, capillary pressure will cover a larger volume of the reservoir than the volume covered by the SCAL. 2017-08-20 A new capillary pressure model is proposed. It is based on previous study, and largely empirical.

2017-04-26 · The Thomeer function has three parameters: the threshold pressure P ct, the pore geometric factor G, and the mercury saturation at infinite capillary pressure S Hg∞. (Thomeer wrote Eq. 15.8 with bulk mercury saturation instead of mercury saturation. In this paper, we developed a novel methodology, based on Thomeer formalism and optimization techniques, for capillary pressure estimation using “standard” log data. With this methodology, capillary pressure will cover a larger volume of the reservoir than the volume covered by the SCAL.

Capillary pressure is a critical property for reservoir modeling. Reservoir engineers use capillary pressure to compute the original hydrocarbon in place and to estimate the ultimate recovery using fluid flow simulation. Traditionally, capillary pressure data are obtained from special core analysis (SCAL).

With the method proposed by this study, synthetic capillary pressure curves can be obtained and applied to petroleum exploration and production.

I also incorporate characteristics of capillary pressure behavior using the classic Brooks-Corey power-law model. The final form of my new proposed model allowed us to predict absolute permeability as a function of effective porosity, irreducible wetting phase saturation, displacement or threshold pressure corresponding pore throat radius, and basic pore size characteristics.
