摘要

In order to solve sand shale sequences tie mystery, four sequences were proposed for Late Messinian, Abu Madi Formation, which is a multi story fluvial channel system recorded and represented completely in the off shore area with maximum thickness about 320 m. Relative energy, accommodation space, sediment supply, reservoir quality and thickness are decreasing with time starting from sequence one to four, from bottom to top respectively. Each sequence containing three system tracks with a definite sand distribution trend, and subdivided into 13 layers with 10 zones and 9 tested reservoirs. Early Messenian, Qawasim Formation complex channel system composed of two sequences underlying Abu Madi channel with 500 m average thickness. Upper sequence (sequence two) is occasionally eroded, it can be subdivided into 6 layers with 5 zones and 4 tested reservoirs. Lower sequence (sequence one) which is preserved but not completely penetrated in all studied wells is characterized by an average thickness about 240m and divided into 5 tested reservoirs in the relatively high structure block in onshore area. Sequences Three and Four in Abu Madi Formation and sequences One and Two in QawasimFormation can be easily discriminated by the different tools and became the main goal in the exploration strategy in the area. Accordingly, three successive exploratories and six development wells were drilled to explore and exploit these sequences and resulted in high daily production rate about 70 Mscft per well achieved.
