Diatomite is a near pure sedimentary deposit consisting almost entirely of silica. The Greeks first used diatomite over 2,000 years ago in pottery and brick. There are many diatomite deposits throughout the world, but those of high-purity which are commercially viable are rare. The properties which make diatomite valuable include low density ...

Mar 08, 1995 Diatomite reservoirs have a very low matrix permeability (generally of the order of 1 md or less), high porosity (40-70%), and high oil saturations (frequently grater than 40%). Because of the low matrix permeability, hydraulic fracturing is the recovery method of choice for light oil diatomite reservoirs.
