Right-sizing ESP systems requires equipment that can deliver the appropriate production rates within the physical constraints of a wellbore. This is especially true in new unconventional drills which typically feature extra-long laterals, slimmer casing sizes, and doglegged sections.
To address this growing need in the market, we developed THE VIKING™ — a powerful slimline ESP motor that packs all the power of our 456 series in a skinnier profile.
In narrow wells completed with 5.5-inch 20 lb. or 23 lb. casing, standard 4.56-inch diameter motors often come close to or exceed the API drift tolerance, which may increase the risk of clearance-related issues.
Boasting a 4.22-inch outer diameter and up to 400 horsepower in tandem, THE VIKING was specifically engineered to deliver maximum horsepower requirements while markedly reducing the risk of equipment snags in tight deployments.
When one Permian operator was grappling with heavy scale buildup and costly fishing delays in a new horizontal well, selecting Valiant for a system redesign proved to be a game-changer.
- Midland Basin
- Wolfcamp Formation
- New horizontal well with 5.5-inch, 20 lb./ft casing
- Well depth: 9,353 ft.
After analyzing the provided well data, our team concluded that implementing THE VIKING would be necessary to slim down the production string without sacrificing production rates. A system featuring 335 stages of enhanced high pressure, abrasion resistant modular VC4300 pumps and two THE VIKING motors was swiftly designed and installed.
After startup, the operator was relieved to see immediate results, achieving consistently stable production and efficiency during the critical payback period.
When the frequency was raised over the next two months of operation, it was found that the motor requirements at 60 Hz were just above 300 HP — well within the capabilities of THE VIKING tandem configuration.
For those requiring a more compact solution, THE VIKING is also available in a single-piece UT configuration to accommodate smaller pumps. This application-dependent versatility ensures that it remains a good fit throughout the entire ESP lifecycle by minimizing wasted capacity.
