TY - JOUR ID - TI - Reservoir units of Mishrif Formation in Majnoon Oil field, Southern Iraq AU - Layla khudhur Abbas* AU - Thamar Abdullah Mahdi PY - 2019 VL - 60 IS - 12 SP - 2656 EP - 2663 JO - Iraqi Journal of Science المجلة العراقية للعلوم SN - 00672904 23121637 AB - The reservoir units of Mishrif Formation in Majnoon oil field were studied byusing available wireline logs (gamma ray, porosity and resistivity) and facies thatderived from core and cutting samples for three wells including Mj-1, Mj-15, andMj-20. The reservoir properties were determined and interpreted by using IPsoftware. The results showed that unit D have the best reservoir properties due tohigh effective porosity, low water saturation and very low volume of shale.Furthermore, a large part of this unit was deposited in shoal environment. The otherreservoir units are then graded in reservoir properties including units B, A, F & Erespectively, except unit C, which is considered as a cap unit, because it consists ofrestricted marine facies so that; it has high volume of shale and water saturation andvery low effective porosity.
