ERS 1.3.8

ERS (Electric Reservoir Stimulation) by Schlumberger is a technology that uses electrical current to enhance oil recovery from reservoirs. It involves injecting electric current through the formation to improve fluid flow and increase production rates.

ERS involves inserting electrodes into the wellbore and connecting them to a power source. Electric current is then passed through the formation, creating electrochemical reactions that enhance reservoir properties and improve oil mobility.

Some of the benefits of ERS include improved sweep efficiency, enhanced well productivity, increased oil recovery, reduced water production, and improved economics of field development.

ERS can be applied to a wide range of reservoir types, including both conventional and unconventional reservoirs. However, its effectiveness may vary depending on specific reservoir characteristics and conditions. A detailed evaluation is necessary to determine its suitability for a particular reservoir.

Potential risks of ERS may include formation damage, equipment failure, increased water production, and uncertain long-term effects. Thorough analysis, planning, and monitoring are essential to mitigate these risks and achieve successful results.

Yes, ERS can be combined with other EOR techniques such as chemical flooding, gas injection, or thermal methods to further optimize oil recovery. Integrated approaches can leverage the synergies between different methods for enhanced results.

ERS typically requires modifications to the well infrastructure, including inserting electrodes, designing suitable power connections, and ensuring proper wellbore integrity. Collaboration with experts and specialized equipment is crucial for successful implementation.

ERS technology is continually evolving, and its applicability has been demonstrated in various field trials and commercial projects worldwide. Schlumberger has successfully applied ERS in multiple reservoirs, delivering improved production performance.

Yes, there are numerous case studies available that demonstrate the effectiveness of ERS in improving oil recovery and reservoir performance. These case studies provide valuable insights into the implementation and outcomes of ERS projects.

ERS technology has undergone extensive research, development, and field testing. It has been proven effective in certain reservoir conditions. However, evaluating its applicability on a case-by-case basis through comprehensive reservoir analysis is necessary.
