QATAR'S OIL AND GASFIELDS: A REVIEW
A. Al-Siddiqi* and R. A. Dawe**
In this
paper, we review the oil- and gasfields located within the State of Qatar, and survey the
discovery and development of hydrocarbons in Qatar over the past 60 years. This
development history can be divided into two phases - before and after 1990. Until 1990,
four producing areas had been identified, one onshore and three offshore. The single
onshore field (Dukhan) has three oil producing reservoirs, beneath which is a
non-associated gas reservoir. Offshore, the first producing area comprises three oil and
associated gasfields (Idd El Shargi, Maydan Mahzam and Bul Hanine); while the second is
the super-giant North gasfield. Qatar also shares with Abu Dhabi the offshore Al-Bunduq
gasfield. Although a number of other areas were explored by seismic survey and drilling,
no further commercial oil was declared. Since 1990, however, there has been considerable
further exploration around the offshore producing areas, and a number of new fields have
been discovered (e.g. Al-Khalij, Al-Rayyan and Al-Shaheen).
