Abu Dhabi Company for Onshore Petroleum Operations Ltd. (ADNOC Onshore) intends to increase crude oil production from the current production rate of 1.4 Million Barrels Oil per Day (MMBOPD) to 1.8 MMBOPD. This increase in production will be achieved by developing different reserves (building block development) in ADNOC Onshore fields. ADNOC Onshore plans to develop the new Thamama-A and Thamama-H zones in Bab field to produce an additional 30 MBOPD which, along with other on-going developments, will sustain a production of 400 MBOPD. At the same time, ADNOC Onshore plans to develop the new Updip & Attic zone to sustain the current production of 300 MBOPD from Thamama-B zone. Currently, in the Bab field, several projects (either completed or at the Execution Stage) are undertaken to develop other new zones such as Thamama-G, Habshan-2 and Habshan-1 which form some of the building blocks producing the required additional 400 MBOPD. These are dealt with separately under various Bab field expansion projects.

The Bab field is located in a desert area, approximately 160 km southwest of Abu Dhabi city (Figure 1.1). The field covers an area of approximately 45 km by 25 km. The main processing facilities are located around Bab Habshan. The field is sour with high H2S content (up to 11% H2S content). The wells to the northeast of Bab field exhibit generally higher H2S content than wells to the southwest. Aquifer water is injected into the producing zones for reservoir pressure maintenance. Associated gas separated at BCDS is delivered to GASCO for processing and processed Crude Oil is pumped to ADNOC Onshore export network.
