This article, written by Technology Editor Dennis Denney, contains highlights of paper SPE 106858, "Technology Integration in the Caspian," by Ian Pannett and David Hodgson, BP plc, prepared for the 2007 SPE Digital Energy Conference and Exhibition, Houston, 11- 12 April.
BP’s Azerbaijan Strategic Performance Unit (ASPU) was developed to meet key challenges of operating within the Caspian region and to maximize business value. Key challenges include complex depletion plans; unconsolidated reservoirs; a difficult-to-drill overburden; and an integrated development, gathering, and export system. To meet these challenges, advanced seismic, intelligent completions, zonal-flow monitoring and control, and field of the future (FOF) technologies collectively address the business challenges.
Integration is key for the Azerbaijan strategy, specifically the technology strategy. The assets and reservoirs are integrated in a variety of ways and designed to operate in an integrated way. This integration is essential to maximize reservoir recovery. As the strategy developed, increased integration could create additional opportunities for performance improvements.
As shown in Fig. 1, the BP-operated assets center on development of two very large hydrocarbon reservoirs in the Caspian [the Azeri, Chirag, and Guneshli (ACG) oil fields and the Shah Deniz (SD) gas development], although it is fully expected that other assets will be added. In addition, BP operates two major pipelines through which these hydrocarbons are exported—the Baku-Tbilisi-Ceyhan (BTC) and the South Caucasus Pipeline (SCP), which originate at the Sangachal terminal, south of Baku. These pipelines are designed to take ACG and SD reserves to market with capacity to take oil and gas from other fields and operators. A fully redundant data network is in place linking all facilities with a high-bandwidth optical-fiber “ring-main” backed up by satellite data systems. Fig. 2 summarizes the ACG full-field development.
The 5-year technology plan integrates all functional and asset-based activities across business areas supporting the ASPU. The strategy includes leadership in a few key areas, efficient deployment of technology in other areas, bias toward rapid application of proven technology, and healthy progression of options in selecting available technologies. This strategy has helped to focus and prioritize technologies.
The technology plan was developed in conjunction with field-depletion plans. The technology plan also was designed to improve ultimate recovery. The current ACG-development plans recover approximately two-thirds of the potential. Obtaining maximum value requires sophisticated reservoir management and application of advanced technologies such as multilateral completions and other enhanced-oil-recovery technologies.
