Petroleum Development Oman (PDO) is the countrys second-largest employer after the government. The company is a consortium comprised of the Omani government (60 percent), Shell (34 percent), Total (4 percent), and Partex (2 percent). It holds over 60 percent of the countrys Oil reserves, and accounts for 85 percent of production. PDOs main hopes of stemming its decrease in production involve increasing recovery rates, and discovering and exploiting new fields, particularly in the south. Among its southern prospects, PDO has the most hope for a cluster of fields that includes Ghafeer, Sarmad, and Harweel. PDO estimates there may be reserves of 250 million barrels in these fields, with a potential maximum production level of 100,000 bbl/d. One small new find was reported in July 2004, in the Shuaiba area in northwestern Oman, which tested at 2,600 bbl/d. PDO awarded a contract to Petrofac of the UK in November 2005 for development of Natural Gas injection infrastructure at the Harweel field. One of the difficulties that PDO will face in the south is the very large water cut in the fields. A proposed solution is the construction of a 300-kilometer (186-mile) Pipeline that will carry water from the south for use in reinjection in the north where "water flooding" already has been used successfully on wells in the Yibal and Bahaja fields.
