The estimates area 296520 acres (1200 km2) could possibly contain 5 billion barrels of original hydrocarbon in place. It should be noted here that the main purpose of this study has been the evaluation of the hydrocarbon potential of the Ghareb and upper Amman formations. A suitable recovery technique is proposing a pilot project for in – situ combustion underground and horizontal producer wells to increase the productivity, reduce the viscosity of the residual hydrocarbons, and should prove to be an economically viable means of heavy oil and asphaltic extraction. The study of a pilot project of in-situ combustion to drill one vertical well for injecting air into the top reservoir, the other horizontal well for injection in the middle reservoir and the third horizontal producing well in the line of the reservoir. If the project proves to be profitable producing 124.43 bbl per day at least which means the recovery of capital expenditure in around 999.9days (2 .732 years ) and the recovery efficiency proves to be high which makes the horizontal producer wells technology to increase the productivity. The project could be expanded in the Azraq region area. The possible method is proposed for thermal recovery of this reservoir, a dry forward combustion and wet combustion underground project is the preferred one or alternatively a combination of steam soaking and steam drive.

INTRODUCTION The purpose of this study is to provide an assessment of the heavy oil and asphaltic residues which occur in the upper Cretaceous (Maestrichtian) Ghareb and upper Amman (Campanion –Santonian ) formations in the Azraq area. In order to assess the nature and distribution of these bituminous rock which is found in the subsurface at depths ranging from 1108.97 ft Wadi Ghadaf to X7 - 3553.32 ft, in the west Azraq area of The Hashemite Kingdome of Jordan. The widespread distribution of bitumen and asphaltic bearing rocks of Maestrichtian age of Azraq region has been clearly established through the drilling of 29 oil exploration wells, 16 of which are located in the Hamza area. Although bitumen, asphalt and heavy oil are sporadic throughout the stratigraphic column, the richest occurrences of heavy residual hydrocarbons are found in the Ghareb formation of late Cretaceous age. The depth to the top of the Ghareb formation in the area study ranges from 2788.85 ft at Well - X2 to a currently recorded maximum of 3553.32 ft at Well - X7 . If pilot tests are to be undertaken in Wadi Rajil – Hamza area. Figure 1 shows the study area, and if these prove
