ESeal 3.0 RF Liner System - The Ultimate Diverter

Complete, cost-effective solutions for today’s refracturing challenges
ESeal ReFrac Liner 3.0

The next generation of expandable zonal isolation products from Enventure

Today’s refracturing challenges require solutions that provide maximum results while managing predictable production results. Enventure’s next-generation Refrac System does both. More than two decades of experience and client collaboration have given us the edge in developing an expandable zonal isolation system that provides

  • Customized refrac isolation solution
  • Largest inside diameter (ID) possible
  • More flow and power to the reservoir
  • Permanent solutions to zonal isolation.
  • Ability to operate in higher temperature reservoirs

ESeal system of mechanical diverters

Enventure’s ESeal 3.0 Refrac System employs solid expandable mechanical diverters. Each is designed to provide refracturing solutions in specific well environments. All effectively create a new wellbore with the maximum ID (inside diameter) for the isolation of existing perforations, thereby providing more flow to your reservoir. This helps you have more power for your refrac – to get a better frac and increased flow area for production afterwards.

Designed to meet your specific refracturing needs

The ESeal 3.0 RF and RF-HT deliver higher pressure integrity by optimizing the expansion process. Both use our Engineered Liner Analysis service.

  • ESeal 3.0 RF - Our next level system utilizes newly enhanced connections that are 16% stronger than the previous generation and are ideal for vertical and horizontal wells in less extreme temperature environments.
  • ESeal 3.0 RF-HT - Our highest rated system, the ESeal 3.0 RF-HT (High Temp) Refrac Liner, uses the toughest connections in the industry: 40% stronger than the previous generation.

Liner Analysis Service

Thanks to continuous feedback from our clients, Enventure now offers a powerful service to calculate the safe operating window for your refrac using any solid mechanical diversion technique. Our Engineered Liner Analysis will allow you to balance cost vs. frac effectiveness and production rates. That analysis will help determine the most effective approach to refracturing.

Considerations in the Liner Analysis

The Liner Analysis estimates tension in the liner for different plug locations by considering the possible ranges of Treatment pressure, downhole temperature, frac fluid density and reservoir pressure and then comparing that to connection ratings to determine feasibility of fracturing solutions. Enventure will walk you through the factors and scenarios that significantly affect the loads or provide the considerations for you to compare with your own internal models.

Benefits to Asset Managers

Regardless of oil prices, you need predictable costs and reliable results when refracturing. Enventure’s next generation Refrac System delivers this by improving upon previous mechanical diversion techniques, which already have the highest success rate and reliability in the industry. Pairing this with our Engineered Liner Analysis service, you can make data-based decisions about your refrac options and choose the most cost effective option from our tiered system.

Benefits to Operators

Today’s oilfield operations are a constant balancing act. You need to optimize ROI and minimize risk during multi-zone isolation and recompletion operations, while balancing cost vs. frac effectiveness and production rates.  Now you can make this balancing act easier with Enventure’s comprehensive Refrac System. Efficient and cost-effective options will enable you to mechanically isolate old perforations to provide internal pressure integrity and zonal isolation, with largest ID possible, providing more flow and more power to your reservoir.
