Square Root K/Ø Methods: Leverett J Function and Flow Zone Indicator (FZI) Technique Whereas the Thomeer method has been used for many years in Shell, in other companies the Leverett J Function method ( Leverett, 1941 ) and the related FZI technique

2019-05-03 · Saturation Height Function kokokyi Uncategorized May 3, 2019 1 Minute Further to the presentation on “Saturation Height Function” (prepared by Mr Leong) which I posted previously, I would like to stress that Leverett-J method of generating SHF is one of the many methods used in the industry. Applying different saturation height models “A saturation height model is an equation that represents the water saturation profile in a reservoir interval as a function of the fluid/rock properties and the distance above the Free Water Level (FWL) and is constructed from capillary pressure data” (Valentini et al. 2017). Presentation to illustrate links between saturation height relationships, permeability and flow prediction. Saturation modeling features.

4. 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. Air Permeability as a Function of Three Pore-Network Parameters, 10.9.3 Other Approaches to Saturation-Height Functions. If core data is not Capillary pressure curves and analysis by Thomeer's equation.

Buiting J (2007) Fully upscaled saturation-height functions for reservoir modeling based on Thomeer’s method for analyzing capillary pressure measurements. In: Paper SPE 105139 presented at the 15th SPE Middle East oil & gas show and conference held in Bahrain International Exhibition Centre, Kingdom of Bahrain

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.

The nearest height in the table is 4.55 meters (column 10) and the corresponding saturation (column 3) is 0.497. Use interpolation or plot a detailed graph for better accuracy.

Highlight matches. Saturation-height functions in oil and gas reservoirs are determined using methods that include quantifying the microporosity of the subterranean formation; determining the distribution of facies and microporosity as a function of depth; and calculating the saturation-height function for a given formation.

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).

Summary: Saturation height function using the Thomeer model The saturation-height function using Flow Zone Index (FZI): •Breakthrough pressure, Pb = 6.4468(FZI-0.7918) •Thomeer Shape factor, C = 0.3174(FZI-0.1586) •Capillary Pressure from height above FWL (m) Pc = (Height above FWL x 62.42762 (ρ w –ρ g ) x 3.28084)/144

This functions correlated data over several orders of magnitude change in permeability. Also, notice that the J function value where most of the saturation change occurs is close to the value of 0.49 for a bundle of identical capillary tubes.
