Al Khalij field offshore Qatar is formed of a highly heterogeneous carbonate reservoir with significant remaining dynamic uncertainties. Moreover, given the current high field water cut, any operation to decrease it can have a large effect on field oil potential. This paper details the design, planning, and execution of the intelligent-completion technology in the field and covers the value generated for field development.
Field Location
The field, discovered in 1991, is located offshore Qatar (60-m water depth) and is adjacent to the Iranian border (please see the complete paper for a reservoir and geological description). The field was put into production in 1997 and has been developed through three successive phases.
In 2013, 42 electrical-submersible-pump (ESP) -activated wells were producing 223,000 B/D of liquid, with an average water cut slightly below 90%. Eight injectors are available for a total injection capacity of 205,000 BWPD. A water-treatment platform, PP1 (adjacent to the DP2 platform), allows an injection rate of 190,000 BWPD on the DP3 and WP3 platforms. On the DP4 and DP1 platforms, injected water is produced from a regional shallow aquifer, Umm Er Radhuma (600 m). The production is exported to Halul Island facilities through two pipes (Fig.
