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.

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.

Are energy storage systems a key component of the energy transition?

Energy storage systems are an important component of the energy transition, which is currently planned and launched in most of the developed and developing countries. The article outlines development of an electric energy storage system for drilling based on electric-chemical generators.

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.

Do drilling rigs have power operating modes?

The article studies power operating modes of drilling rigs, provides general conclusions and detailed results for one of more than fifty pads. Based on the research, a generic architecture of the energy storage module is developed, and an engineering prototype is built.

What are the benefits of powering drilling rigs?

1. Capital costs of powering drilling rigs are reduced with tings check once per shift. Also, the ESS does not need 2. The diesel fuel consumption will be reduced by up to 3. The DPS life cycle increases by up to 40% due t o the 4. The service life of frequency con verters, the momentum 5. The energy efficiency of drilling is improved through
