                  Geological Atlas
                  The idea of the North African Petroleum Geological Atlas (NAPGA) project is to give easy and inexpensive access
                  to the accumulated knowledge held by several organisations on the basins of the area and to help gaining a bet-
                  ter understanding of the geology of North Africa. It is to present a comprehensive and systematic overview of the
                  results of over 100 years of petroleum exploration and research in the North African region, including Morocco,
                  Algeria, Tunisia, Libya and Egypt. Publication will be both in paper and digital (GIS) format. It follows the successful
                  launch in 2003 of the ‘Millennium Atlas: petroleum geology of the central and northern North Sea’ and the highly
                  successful Petroleum Geological Atlas of the Southern Permian Basin Area (2009).

                                      The Gemsa oil fields in Egypt and the Ain Zeft oil field in Algeria were the first discoveries in the
                                      North African region during the period 1907-1910. Important discoveries in this region include
                                      giant fields like Hassi Messaoud in Algeria (more than 10 billion barrels of oil and 8 Tcf of gas) and
                                      Attahadi in Libya (some 10 Tcf of gas). To date, more than 101 billion barrels of liquids and 378 Tcf
                                      of gas have been discovered in the North African region. As the petroleum provinces within North
                                      Africa continue to mature, and with field sizes decreasing, more careful data integration and
                                      geoscientific effort will be required to discover new reserves and to augment the recovery of
                                      proven hydrocarbon accumulations. The large volumes of data that are or will be made available
                                      publicly will allow production of an authoritative compilation to support the E&P industry in their
                                      efforts to fully develop the basins within the region in the coming decades. At the same time, easy
                                      and inexpensive access to the accumulated knowledge held by educational organisations will lead
                                      to a better understanding of the geology of North Africa. The documentation of this knowledge
                                      will assist in training the next generation of petroleum geologists.

                                      The North African Petoleum Geological Atlas is a joint project of the National Oil Companies in
                                      North Africa and the Geological Surveys of the Netherlands and the United Kingdom. The aim of
                                      the Atlas, which will be published in 2015, is to present a comprehensive overview of the results of
                                      over 100 years of petroleum exploration and research in the North African region. The Atlas aims to
                                      stimulate the petroleum E&P industry to continue their activities in the region by cooperation
                                      between (national and international) Oil Companies, universities and research institutes. By
                                      sharing the knowledge and experience acquired in previous Atlas projects the project will assist in
                                      training petroleum geologists employed in the North African region. Subsurface characterisation
                                      will also be of great value to governments, researchers and other individuals interested in the deep
                                      subsurface. With this in mind, it is intended to make the Atlas available at a low price, so it will be
                                      accessible to a wide audience. We are confident that this publication will become the definitive

  Atlas’ contents
                            The Atlas will review the entire North African region, covering Morocco, Algeria, Tunisia, Libya
                            and Egypt. If desirable, parts of Mauritania and Mali could be included. The area under review
                            is situated between latitudes 25 and 38 degrees North (see maps).

                         The Atlas will address the geological evolution and hydrocarbon potential for each stratigraphic
                         interval. The paleogeographic and tectonic evolution will be described within the framework of
                         the principal stratigraphic intervals, from the Neoproterozoic basement to the Holocene. The
                         structural and stratigraphic settings will be elucidated by a detailed set of field examples,
                         overview maps and illustrations. In addition, petroleum generation, migration, trapping and
                         production, as well as the history of exploration and licensing in the North African region, will be
                         covered, together with a summary of resource assessments. Other potential options for use of the
                         deep subsurface such as gas storage and geothermal aspects will also be addressed. The Atlas
                         content will be generated through contributions from international experts, geological surveys
                         and petroleum exploration companies.

                         The Atlas will be available on printed paper (A2 size) and on CD in an interactive PDF format.
                         All attribute data and spatial data (rasters and vectors) will be offered digitally on DVD or will
                         be made online available through a GIS. The GIS will be developed for viewing spatial and
                         attribute (tabular) data such as depth maps, well attributes and oil and gasfield attributes. This
                         will greatly increase the utility and accessibility of the maps, and will allow their integration with
                         other, perhaps more detailed datasets. It will also enable user-defined web-based access to the
                         Atlas content and hence provide an invaluable training tool for postgraduate students and for
                         new graduates employed by the petroleum industry.

                         The project would be launched at the EAGE Conference scheduled for March 2011 and will take
                         four years to complete. A Steering Committee will be established that will consist of mainly
                         representatives from the North African National Oil Companies, the Sponsors (E&P industry) and
                         from the main data providers. TNO will manage the project and compile the database and GIS; the
                         British Geological Survey will edit the Atlas; PESGB will support in training courses.

                 An estimated budget of at least EUR 6 million will be required, in
                 addition to free author commitments and data supply. In order to
                 produce a high-quality Atlas with very a low purchase price, it is
                 intended to fund the project through corporate sponsorship by
                 companies/agencies from all sectors that would benefit from further
                 development of the hydrocarbon industry in North Africa (e.g.
                 exploration, development, contracting, banking and law). A number
                 of different sponsorship levels will be determined, reflecting the size
                 and activity levels of the various companies or agencies:
                 • For multinational companies with a high level of involvement in
                   the North African region we would request their support as Patrons
                   by sponsoring a certain amount. These Patrons will have their
                   company profile and corporate logo displayed in the Atlas.
                   Representatives of such sponsors would be appointed as members
                   of the Steering Committee.
                 • For companies active in one of the participating countries, or with
                   a relative low level of involvement in the North African region, we
                   would request a lower sponsorship amount. These sponsors will
                   have their corporate logo displayed in the Atlas and an
                   acknowledgement of their support.

                 Several parties have already expressed their interest in participation
                 in this exciting project, such as several National Oil Companies, E&P
                 companies and some data providers such as IHS, TNT and Lynx.
