Of the conventional "equation based" approaches, the Thomeer and Skjaeveland models appear to have the most utility and are recommended as first choice saturation-height models to test. The two best known methods to analyze MICP measurements and to estimate saturation height curves are Thomeer-and Leverett J functions. However, neither method has been satisfactorily upscaled until now.

Methods disclosed herein may create a saturation-height function by: quantitatively measuring microporosity, using techniques such as laser scanning confocal microscopy and/or MICP data; determining the distribution of facies and microporosity as a function of depth using techniques such as conventional openhole logs, core, borehole images, nuclear magnetic resonance (NMR) logs, and analysis of sequential core samples using confocal microscopy and/or MICP; and evaluating the effect of 2015-06-24 · In a manner similar to that described in the previous P c /S w section, height/saturation curves are often fitted to these resistivity-log-derived S w data to enable reservoir hydrocarbons-in-place volumes to be calculated. The function forms are similar to or are the same as those described above for P c /S w.

Primary Drainage Saturation-Height Modeling pieces of special core analysis to produce these capillary pressure-derived saturation functions. A Thomeer water saturation model was used for fitting parameters, such as irreducibl Wettability, capillarity, relative permeability and residual oil saturation are capillary pressure responses of rocks (Corey, 1954, Thomeer, 1960, Brooks an average gas saturation, and a saturation-height function, but not necessa Resistivity 'driven' by Phi and Saturation-Height(Pc), input to Archie Thomeer, J.H.M.

Workshop. Day 4 will cover show how to convert lab measured capillary pressure data to reservoir conditions to determine height above free water, seal capacity and initial water saturation. The use of the Thomeer method for the Arab D Reservoir at Ghawar is focused on three issues: (1) facies-dependent saturation-height modeling; (2) free-water level determination; and (3) facies-dependent recovery estimation.

The Thomeer function has three parameters: Threshold pressure P ct; Pore geometric factor G; Mercury saturation at infinite capillary pressure S Hg∞ (Thomeer wrote Eq. 3 with bulk mercury saturation instead of mercury saturation. Bulk mercury saturation equals the product of porosity and mercury saturation. The saturation height functions can describe the drainage process during the hydrocarbon migration and are expressed as a relationship among the saturation, the height above the free water level and some model properties (commonly porosity and permeability). Saturation-Height Equations There are various practical techniques for correlating capillary pressure curves according to rock type for a heterogeneous formation and generating field wide saturation-height function that relates capillary pressure curves to porosity, permeability or rock type in general. The classic method is based on Saturation Height Functions Saturation Height functions (SWH, Swht) are a means of assigning a saturation to a volume of rock e.g. a geocell which is not penetrated by a well by virtue of that cells porosity, permeability and capillary pressure.

Saturation Height Function In the oil and gas industry the description of the hydrocarbon volume is one of the key disciplines. The hydrocarbons initially in-place (HCIIP) are defined as: HCIIP = Gross Rock Volume x Net-to-Gross x Porosity x Hydrocarbon saturation The two best known methods to analyze MICP measurements and to estimate saturation height curves are Thomeer-and Leverett J functions.
