The Resource Estimation and Geologic Risk Assessment for the Southern Structure Belt in Block 69, Yemen

Block 69 in Yemen is characterized by several poor oil forming conditions, such as being low in trap confirmation and poor reservoir quality etc.. Though three wells have been drilled, no commercial hydrocarbon discovery has been made, showing the great difficulties for oil and gas exploration in the block. The author, on the basis of analyzing the oil and gas accumulation conditions, has performed trap conformation in the block and carried out trap resources estimation and geologic risk assessment, thus suggested that the Prospect-1 trap is the most favorable drilling target in the future.
