victimisation Pore-Cor to Model Mercury Porosimetry, Absolute Permeability and Formation Damage
Pore-Cor croup be used to obtain enhanced information from the hydrargyrum intrusion porosimetry of oil-reservoir sandstone core plugs. Although the geometry of the PoreCor vane is simplistic, it is nevertheless flexible comme il faut to closely simulate the percolations properties of actual sandstone samples. Also, crucially, it makes an allowance for the shielding of macroscopicalr pores by small throats, which is not allowed for in the implicit dandy capillaric approximations commonly used. As an example, we show how the method was applied to a core plug supplied by Oil Plus from a Chevron Texaco oil field. It was found that the permeability reduction repayable to colloid occlusion / formation damage is later (i.e. commences at high sizes of included species) and then drops faster than the capillary bundle model. The resulting whole carrel, when occluded by colloid, shows clearly the blocking of access to large pores by small occluded throats. These effects can immediately be viewed in virtual reality. Other properties, such as the effect of polymer pore plugging, and the extent of fast wetting of samples, can also be calculated.



Before using Pore-Cor RS on their testify samples, all users should work through the PoreCor tutorials in the Pore-Cor RS sustain system, in particular the Application Tutorial on Porous Rock. This Help system is supplied with the software, and is also downloadable from http://www.pore-cor.com/downloads.htm . Attendance at a two-day training course is also recommended. Introduction The Pore-Cor void network comprises unit cells with periodic boundary conditions. Each unit cell is made up from up to 1000 cuboidal pores, connected by cylindrical, oval-cross sectioned or slit-shaped throats. Fluid is intruded at the xy rag at maximum z in the z statement i.e. from the top surface downwards in Figure 1.
