Bulla-Deniz

Location and Operator

The Bulla-Deniz field is situated in the Caspian Sea, off the coast of Azerbaijan. It is operated by Azneft Production Association, which is part of the State Oil Company of the Republic of Azerbaijan (SOCAR).

Field Characteristics

• The field is a conventional oil field located in shallow water, with sea depths ranging from 10 to 25 meters.
• It is one of the several offshore fields in Azerbaijan, contributing to the country's oil and gas production.

Operational Details

• The field has been in operation for several years, with ongoing production activities managed by Azneft Production Association.
• The drilling operations in this field involve complex well profiles, such as J-profile wells, which require advanced drilling technologies. For instance, SOCAR and Schlumberger collaborated on a project to drill a J-profile well in the Bulla Deniz field, using specialized equipment like the PowerDrive X6 RSS and Rhino XS reamer to overcome formation and well-plan challenges.

Drilling and Technological Innovations

• The drilling operations in Bulla-Deniz have involved the use of advanced technologies to address the complex geological and operational challenges. This includes the deployment of a customized Bottom Hole Assembly (BHA) that integrates the PowerDrive X6 RSS and Rhino XS reamer for directional drilling and underreaming capabilities. Additionally, services like arcVISION and TeleScope are used for real-time logging and interpretation.
• A notable achievement in this field was the successful drilling of a complex well profile without non-productive time (NPT), stuck pipe, or tool failures, completing the objectives 79 days sooner than the planned 118 days.

Geology and Production

• The target formations in the Bulla-Deniz field are characterized by lithology that can slow the rate of penetration (ROP) during drilling. The field operates in high mud weight conditions, which adds to the complexity of the drilling process.
• Despite these challenges, the field has been successfully producing oil and gas, contributing to Azerbaijan's overall energy output.

Historical and Current Production

• While specific current production figures for the Bulla-Deniz field are not provided in the sources, it is part of Azerbaijan's broader oil and gas production landscape. Azerbaijan as a whole produced about 33 million tonnes of oil and 35 billion cubic meters of gas in 2022.

In summary, the Bulla-Deniz oil and gas field is an important offshore production site in Azerbaijan, operated by Azneft Production Association. It involves complex drilling operations and utilizes advanced technological solutions to overcome geological and operational challenges, contributing significantly to Azerbaijan's oil and gas production.
