Libya Reservoirs – Phase I, Onshore Basins

Reservoir characterization data pertaining to reservoirs of fields and basins of Libya is critical to many companies’ evaluation of opportunities in Libya. This data is generally not available to companies other than NOC. With much of the archived data of 1960’s and 70’s vintage; a new consistent and compatible dataset, and evaluation of that dataset has not been previously conducted on a regional scale.

Core Laboratories and Petroleum Research Center, NOC have obtained approval to describe, sample and analyze cores and cuttings samples from approximately seventy (70) wells from producing fields and exploration wells in all of the onshore basins in Libya All the major reservoir formations will be evaluated in this study.

The proposed study will focus on determining the sedimentological and fracture characteristics of the reservoirs, along with their petrographic and petrophysical properties. In addition, high resolution, quantitative biostratigraphical analyses will be performed on drill cutting samples in order to place the reservoir intervals into a regional stratigraphic framework. The analysis of seal rocks and their hydrocarbon column capacity will compliment the reservoir description. These types of data and interpretations, integrated into a regional evaluation, will significantly enhance participating companies’ understanding of these reservoirs for improved exploration and exploitation efforts. The final report will be available in hard copy and HTML formats.

The project has been divided into two phases which are available separately:

  • West Libya (Ghadames and Murzuq Basins)
  • East Libya (Sirt Basin)

The primary objective of the project is to provide each participating company with detailed geological, biostratigraphical, and petrophysical characterization and evaluation of numerous conventional reservoir and seal cores taken in all major basins of Libya. This large database will significantly improve participating companies’ understanding of the reservoirs and result in more successful exploration and exploitation of these fields.
