The Khuff gas is the main source of energy in the State Of Bahrain. The production from Khuff reservoir was started in 1969 when the country decided to embark into a major industrialization program. Since that time, 20 wells were drilled and completed in the Khuff zones and all these wells have been producing smoothly and without any major mechanical failure.

Recently, the later stage wells which are mostly in peripheral locations have exhibited some problems like relatively low deliverability compared to other Khuff wells, high H2S production and downhole scaling problems.

This paper discusses the recently detected problems and suggests remedial work. Also, it proposes modifications in the current completion of Khuff wells specifically the completion design, completion fluid, sequence of perforation, testing and stimulation of the producing zones.
