ColibriESP – A Revolution in Oil Production

Today, the market for electric submersible pump installations (ESP) is quite saturated; this technology is a priority for oil well operation and the primary method of oil extraction. However, Novomet offers a solution that is unique on the global stage.

ColibriESP systems are pump installations that are lowered into the well on a load-bearing cable.

- The main goal of the technology is to move away from drilling rigs and the costs associated with the work of well maintenance crews (current and capital repairs), which are used to lower and raise traditional installations, - says Dmitry Shevtsov, head of the design bureau at Novomet. - This is especially valuable for offshore projects, as elevators on marine platforms are extremely expensive, and for wells with complex structural profiles where ordinary installations cannot be delivered.

Problems solved by the Colibri technology:

• Time savings
  • lowering the installation on a load-bearing cable is faster than lowering it on pipes, with a descent speed of 1 m/s.
  • there is no need to jam the well to conduct lifting and lowering operations (LLO).

• Cost savings
  • there is no need to engage a drilling rig for LLO.

• Increased flow rate
  • lowering the installation to greater depths compared to traditional ESPs due to its compact size

Thus, Novomet's solution is currently unique in terms of cost and ease of installation. The system ensures minimal capital and operational expenditures for onsite implementation – only a reinforced load-bearing cable is needed. Installation and lowering within the tubing string takes just 3 hours.

ColibriESP is produced both in a basic version – for operation in reservoir fluids up to 120 degrees Celsius, and with the possibility of installation in high-temperature reservoirs – up to 170 degrees Celsius. Additionally, the company's specialists are developing installations resistant to hydrogen sulfide, which presents significant prospects for gas well development. Novomet already has successful experience implementing installations in gas fields.

Another significant advantage of this development is the ability to install and dismantle it on an un-killed well. With traditional installations, work can only be performed after jamming the well, meaning it must first be filled with water and then pumped back out, which takes time and money. Novomet's technology allows for substantial savings by bypassing this step.

In conclusion, ColibriESP enables lifting and lowering operations without expensive equipment and service crews, allows work on an un-jammed well, including in gas fields, and features ultra-compact equipment. The reduction of capital and operational costs for development and mechanized extraction is the best solution created by our specialists!
