for Hydrocarbon Exploration New Opportunities for Hydrocarbon Exploration in Offshore Atlantic Morocco Ladies and Gentlemen, Good morning! I am very pleased to make this presentation in this important event of the petroleum industry about the New opportunities for Hydrocarbon Exploration in offshore Atlantic Morocco. Mohamed EL ALJI ONHYM March 3, 2010
Outline Introduction Exploration Status Petroleum System Open Acreage Play Concepts & Prospects The outline of the presentation includes a brief introduction of Morocco, then …………….. Summary of Atlantic Prospetivity March 3, 2010
Morocco Profile of an Attractive Destination Open & Growing Economy Challenging and Promising HC Potential Attractive fiscal terms There are many reasons that make Morocco an attractive country for exploration. Its geographic location in the crossroads between Europe, the Middle East, the sub-Saharan Africa and the Americas; Open & Growing Economy with growth rate of about 5% over the last 5 years. Morocco has a stable socio political environment. Challenging and Promising HC Potential Attractive fiscal terms and Finally; It has also world class basic infrastructures. Robust infrastructure March 3, 2010
Morocco Exploration Status Variety of thick Sedimentary Basins (S.B) Under- explored S.B onshore & offshore 3 500 Km of Coast line Where adequately explored, these S.B have produced HC Let’s go to the EXPLORATION STATUS Morocco, as shown this geologic map offer a variety of sedimentary basins onshore and offshore ranging from Precambrian and Paleozoic in Zag and Anti Atlas, Mesozoic in the Atlas Domain, Tafaya lagwira, the Rif and the offshore atlantic and Cenozoic basins in the Garb, Guercif and Mediterranean sea. Most of these S.B are Under- explored. For example with 3 500 Km of Coast line we have only 33 exploratory wells. Where adequately explored, these S.B have produced HC. In the last decade; Adequate data base has been acquired in some S.B These data base leads to the definition of Myriade of Play concepts. Adequate data base acquired in some S.B. Myriade of Play concepts defined March 3, 2010
Petroleum Exploration Activities in Morocco Achieved objectives: 2010 Partnership Portfolio: 133 Exploration Permits 4 Reconnaissance Licenses 10 Concessions The promotional effort done by ONHYM during the last decade allows the increasing of Partnership Portfolio, as you can notice in these two maps: The first one in 1997 with few partners located mainly in the offshore and Gharb basin, and the second one in 2008 with 29 partners active in 110 Exploration Permits, 7 Reconnaissance licenses (onshore) and 10 Concessions for production You can notice that only a few onshore areas still open. March 3, 2010
Morocco 18 Blocks offshore 12 blocks onshore Open Acreage status The actual open acreage situation is shown in this map with - 21 Blocks offshore - 05 blocks onshore - 5 of these blocks are under négociations March 3, 2010
Open Acreage Petroleum Systems March 3, 2010 Now we will have a look to the petroleum system of the offshore open acreage. I will start first by presenting the chronostratigraphic chart of the Moroccan sedimentary basin then I will develop the elements of the Atlantic offshore petroleum systems. March 3, 2010
SOURCE ROCKS Petroleum Systems March 3, 2010 For the source rock they are aged within the Jurassic-Upper Cretaceous interval. March 3, 2010

RESERVOIR ROCKS Let us move to the resrvoirs March 3, 2010
Reservoir Rocks: Lower and Middle Jurassic Lower Cretaceous Petroleum Systems Reservoir Rocks: Lower and Middle Jurassic Lower Cretaceous Upper Cretaceous Tertiary Concerning the U C reservoirs, it’s well documented so far just in outcrops along the Atlantic cost and need more investigations in deep offsore. March 3, 2010
Reservoir Rocks (Data Evidence from wells) Jurassic Carbonate Tarfaya - 1 - 100 m net reservoir with an average porosity of 13.7%. MO - 5 - 330 m net reservoir with an average porosity of 15%. Lower Cretaceous 15A – 1 - 88 m net sandstone with an average porosity of 20%. 51a - 1 - 287 m with an average porosity of 15%. Upper Cretaceous 47a - 1 - 30 to 75 m of sandstone with an average porosity of 15-25%. 51a - 1 - 200 m of limestone with an average porosity of 25%. Tertiary 51a - 1 - 80 m of silty limestone with an average porosity of 30%. 15a - 1 - 24 m of limestone with an average porosity of 20%. DSDP 369 & 379 - Turbidite with porosity up to 25%. We have also data evidence of the reservoirs from wells. Here, I will show hou some examples of them from different ages: March 3, 2010

Summary of Atlantic Prospetivity Seismic mapping identified more than 210 prospects and leads of various types; Data evidence from wells and outcrops show good Source Rocks; Data evidence from wells, outcrops and 3D seismic interpretation supports the presence of various levels of reservoirs; The Open Acreage in the Atlantic Deep Offshore offers many attractive 3D & 2D leads and mature prospects. At this stage, a substantial drilling efforts is necessary that will led to future discoveries. March 3, 2010
