Oman has awarded BP a concession to develop two large natural gas fields onshore Oman, said Ministry of Oil & Gas technical adviser Khalifa al-Hinai.
Reuters quoted al-Hinai as saying that Oman expected the production of large quantities of gas from the tight gas reserves in the Khazzan and Makarem fields, which cover 2500 square kilometre near existing gas fields operated by state-owned Petroleum Development Oman (PDO).
Omani Oil Minister Mohammed al-Rumhy said last month that eight international consortia had sent proposals to the Ministry of Oil & Gas in Muscat for the development.
Rumhy declined to give any estimate of the gas reserves in the geologically complex field, which has three reservoir structures with low permeability. Since the gas in place is difficult to flow, complicated techniques are needed to develop the field.
An official from Petroleum Development Oman (PDO) said recently that the Khazzan-Makarem area holds an estimated 20 trillion cubic feet of gas in-place but low permeability means that it is uncertain how much can be produced.
Other oilmen agreed recoverable reserves are uncertain and will not be known until much more work is done. Some think they are in the range of 6 Tcf to 8 Tcf, while others think potential could be even higher than 20 Tcf.
