Successful First Commercial Production of Halfaya Field – Feedback on Mishrif

The Halfaya field, discovered in 1976, is located in the south area of Iraq towards the border with Iran in the Amara region. The field structure is an anticline of about 10 km width by 30 km length with several oil bearing reservoirs of Cretaceous to Miocene age. These reservoirs in either carbonates or clastics formations contain large volumes of hydrocarbons (>16 Gbbl OOIP), the Mishrif reservoir containing around three fifths of the OOIP. First Commercial Production commenced on June 16th 2012 with contribution from 27 wells including 6 originally existing producers. With the rapid development of the Mishrif reservoir, a large data acquisition program was carried out. The 30 new wells penetrating the Mishrif were fully logged with a standard suite of tools and some wells were logged with Nuclear Magnetic Resonance or imagery tools.
