Production optimization allows to increase productivity from the existing fields and uses encompass several areas of interest. In this context, contributes can come from the application of different technologies.
1. Intelligent Well Completion
An Intelligent (Smart) completion is a well that contains a “Remotely Operated Adaptive Completion System” which provides real-time data and the capability to re-configure the Well architecture without well interventions.

The system is able to collect, transmit, and analyze reservoir production data and to proof completion integrity, and to enable remote action to better control reservoir, well, and production processes.
2. WELL PRODUCTIVITY
Ideal Well productivity is the final goal of Production Optimization. In particular, well productivity is determined by a well inflow performance and in this context, a common approach is “Nodal Analysis”. It is a system analysis approach applied to analyze the performance of systems composed of interacting components.

3. WELL STIMULATION
Well stimulation is a term describing a variety of operations performed on a well to improve its productivity. Stimulation operations can be focused on the wellbore or in the reservoir. They can be conducted on old wells and new wells and they can be also designed for remedial purposes.
There are two main types of stimulation operations:
Matrix stimulation is performed below the reservoir fracture pressure in an effort to restore the natural permeability of the reservoir rock. Well matrix stimulation is achieved by pumping acid mixtures (acidizing) into the near-wellbore area to dissolve the limestone and dolomite formations or the formation damage particles between the sediment grains of the sandstone rocks.
Hydraulic fracturing is the most common mechanism for increasing well productivity.
4. SAND CONTROL MANAGEMENT
When the oil is produced from relatively weak reservoir rocks, small particles and sand grains are dislodged and carried along with the flow. This sand production can create erosion in flowlines and other equipment. Sand management can be considered as a key issue in field development in most of the world’s oil and gas fields.
