Oil Field Development

Summary

In hydrocarbon exploration and production, it is important to clearly identify the structure and properties of the underground hydrocarbon accumulation and accommodate them in surface facilities. The reservoir field data is the basis for development of exploration and production planning, which takes into account the economic efficiency and lifecycle cost of the development.

Development Planning

After obtaining mining concession rights and confirming the existence of crude oil, a development plan is prepared. Based on the evaluation of reservoir analysis results, the development planning of the field including the facilities planning is established to optimize the crude production. In this planning, crude recovery is maximized considering the production profile, crude properties change over the production lifetime Additional development may be required in the interim of production phase. It is important to optimize the development cost over the exploration and production life, including initial costs required until the start of production, the development period prior to production and the facility expansion, to accommodate the change of the production profile during the life of production.

Oil field development planning and implementation

The production profile of the oil field is clearly identified by drilling exploration wells, and conceptual planning geared toward production is performed while revising the development plan prepared in the initial stages. It is important that the plan in the initial stages has sufficient tolerance, because the development conditions and other factors have not yet been fully understood. However, too much wider tolerance could increase the initial costs required. At the same time, it is also important to study the environmental impact in the greater interests of global environmental conservation. Since the reservoir performance differs according to each oil field, experience and successful outcomes related to oil well development are necessary when establishing a development planning. Furthermore, detailed consideration is necessary not only for the change in crude oil production and composition over the production lifetime but also for seasonal and daily fluctuation.

Production monitoring and secondary and tertiary recovery

After production starts, production monitoring comes to play an important role. It is important to monitor and record the moisture content of the product, the properties of the crude oil and the pressure decline during the production. Such reservoir performance monitored provide the basis for the selection criterion for appropriate secondary and tertiary recovery methods.
In general, the production process moves from primary production, secondary recovery, and to tertiary recovery. Primary production means using natural energy stored in the reservoir as a driving mechanism for production. Secondary recovery would imply adding some energy to the reservoir by injecting fluids such as water or gas, to help support the reservoir pressure as production take place. Tertiary recovery, known as Enhanced Oil Recovery (EOR), seek for production techniques after primary and secondary recovery methods. Production and recovery methods shall be optimized based on the reservoir dynamic behavior over the lifetime of the production.
