==Reservoir pore geometry and pore type==

Most of the [[porosity]] in the vuggy packstone facies is molds and vugs developed by solution of micrite, algal clasts, and skeletal fragments. There is a range in sizes of the vugs. Most of the larger vugs are connected and effective. Smaller pinpoint vugs and molds lack interconnection and are ineffective. The vuggy packstone facies also contains intergranular (partly modified to intercrystalline) meso- to macroporosity. On the basis of SEM analyses, the particles are larger than 50μ (equivalent to very fine-grained sand). [[Capillary pressure]] data and petrographic analyses indicate the vugs and intergranular pore throats are large, 4-10μ, and well sorted. The r₃₅ analyses (port size) puts the reservoir facies in the macropore type.
