Yemen Rock Catalog


Core Laboratories completed a project to measure, document and interpret, in a catalog format, an extensive array of geological and petrophysical properties for Cretaceous, Jurassic and Paleozoic reservoir rock types in the Republic of Yemen. The analyses was performed on conventional core samples selected to represent the full spectrum of various reservoir rock types encountered in clastic and carbonate producing and potentially producing formations. The various rock types and their associated data in the Yemen Rock Catalog serve as reference analogs for more accurate estimates of formation parameters, producibility and reservoir behavior of non-cored reservoir intervals. The catalog will also supply geologists and engineers with analog data and parameters for modeling reservoir behavior and making reservoir management decisions.

The study is patterned after our Worldwide Rock Catalog™ which characterizes and evaluates the geological, petrophysical and engineering properties of sandstone and carbonate rock types on a worldwide basis. The Worldwide Rock Catalog is organized and presented in a standardized format which serves numerous member companies as a primary source of rock property data covering a broad spectrum of reservoir rock types for improved exploration and production related formation evaluation. Core Laboratories developed the Yemen Rock Catalog which focuses on the spectrum of clastic and carbonate rock types found in the Republic of Yemen.

The objectives of the Yemen Rock Catalog are the same as for the Worldwide Rock Catalog:

  • Provide a reference manual containing “analog” sandstone and carbonate rock types for more accurate estimates of formation parameters
  • Establish a comprehensive geological and engineering data base over a spectrum of sandstone and carbonate rock types
  • Define relationships and correlations between laboratory measured petrophysical data and estimates of reservoir rock properties from visual observations of core, sidewall, and/or rock cuttings material
