Abstract:

AG Formation in northeastern Muglad Basin of Sudan can be divided into lower,middle,and upper sequences.The lower sequence, formed in the early chasmic stage of the basin,mainly consists of rapidly accumulated coarse sediments.The middle sequence,deposited in the spreading period of the basin,is an important interval with well developed source and reservoir rocks in Muglad basin.The upper sequence is mainly composed of fluvial formations, deposited in the shrinking stage of the basin.Comprehensive evaluation shows that the middle sequence with favorable combination of source,reservoir and cap rocks is an important series of strata for exploration in AG Formation in Muglad basin.The middle sequence in the eastern gentle slope zone is the most favorable play,where the prospect I is a relatively mature exploration target.

Key words: Muglad basin, sequence stratigraphy, series of strata for exploration, play, exploration target
