Drilling hybrid energy storage system diagram

Can hybrid energy be used to power a drilling rig?

In this article, the aim is to develop a model for efficient energy management using hybrid energy to power a drilling rig. This involves utilizing wind turbines and emergency generators, as well as charging battery storage systems with recycled energy from the depot through regenerative braking.

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.

Can a hybrid energy accumulation system be integrated into a rig power circuit?

The efficiency of using a hybrid energy accumulation design is proven; the design calls for joint use of Li-ion cells and supercapacitors, as well as three-level inverters, to control the storage system. The article reviews all possible options for connecting the system into a unified rig power circuit, and the optimum solution is substantiated.

What is a hybrid energy storage module?

Based on the research, a generic architecture of the energy storage module is developed, and an engineering prototype is built. The efficiency of using a hybrid energy accumulation design is proven; the design calls for joint use of Li-ion cells and supercapacitors, as well as three-level inverters, to control the storage system.

Can energy storage systems improve energy eficiency of DPS-powered rigs?

Based on average daily power consumption statistics and load diagrams for various rig operating modes at more than fifty pads equipped with DPS, it was proposed to improve the energy eficiency of individual DPS-powered rigs by introducing energy storage systems (Fig. 1).

How a drilling rig is powered by a diesel generator?

According to the conditions of drilling string movement, P1 power from the diesel generator was used to feed the drilling rig and P2 power was used to charge the battery bank. The power of P3 stored in the battery and hybrid energy will be fully able to supply the energy required by the drilling rig during low consumption hours.
