Oil drilling energy storage

How can energy storage improve land drilling operations?

Overall, energy storage solutions integrated with natural gas, dual-fuel, or diesel technology can reinvent land drilling operations by lowering fuel costs, maximizing capital efficiency, and meeting lower emissions regulations. This hybrid system is a significant reduction in the total cost of ownership for drilling contractors and operators.

Can electric energy storage systems be used for drilling rigs?

The work to develop electric energy storage systems for drilling rigs has been underway worldwide for the last 5 years, however, mainly targeting isolated offshore rigs.

Which rigs have energy storage systems for onshore drilling?

The energy storage system developed for onshore drilling is among the world’s first ones. As a foreign analog, only the project of the German rig manufacturer Bentec implemented in Oman can be highlighted. In 2017, the container-type 0.9 MW Bentec ESS with a storage capacity of 0.3 MW was put into trial operation on the KCA Deuteg T-94 rig.

Can electric energy storage be used for drilling based on electric-chemical generators?

The article outlines development of an electric energy storage system for drilling based on electric-chemical generators. Description and generalization are given for the main objectives for this system when used on drilling rigs isolated within a single pad, whether these are fed from diesel gensets, gas piston power plants, or 6–10 kV HV lines.

Why do drilling rigs need a permanent energy source?

An energy source permanently integrated into the rig circuit will allow drilling contractors to compensate for voltage dips and surges, which will reduce emergency shutdowns and downtime of drilling equipment (Chervonchenko and Frolov 2020), minimize drilling hazards, and improve the DPS operation stability.

What makes a good energy storage system?

Due to specific requirements of land-based drilling rigs, the energy storage system ought to be robust, compact and easily transportable, and characterized by inherently high operational safety.
