Operators are facing tremendous challenges with being able to optimize their frac designs while minimizing risks of:

  • Fracture driven interactions or FDI (also known as “frac-hits”)

  • Well integrity failures

  • Production impairment/effects

  • High CAPEX from fraccing operations

Solution: Viking’s Frac-Hit Minimization Process

Viking Engineering has developed the “Frac-Hit Minimization Process” or “FHM” to address these critical concerns in the industry for unconventional plays. The FHM Process is a holistic workflow that incorporates all areas and proprietary knowledge-base as mentioned below into one complete and seamless process.

The goal is to ensure a fit-for-purpose well design, for the completion/fraccing and production requirements of the well based on the reservoir at hand.

The FHM Process – Foundation

FHM’s foundation is based on Viking’s proprietary knowledge-base:

  • Frac-Hit Risk Quantification

  • Failure Investigation Database

  • GATE Phro™

Frac-hit or FDI Risk Quantification

This unique process is able to quantify potential risks to operators pertaining to FDIs and helps optimize completion/frac designs to maximize production while minimizing frac stages.

The evaluation consists of analyzing all pertinent variables including geologic factors such as faults, frac orientations, stress ratios, well spacing, well trajectories, and other. The evaluation also consists of analyzing well designs and applicability to reservoir requirements from a fraccing and production perspective. A risk component to well design and well integrity also plays a key role in the process.

Well Failure Database

Viking’s FHM process is able to provide potential well integrity failure risks and probabilities by utilizing a proprietary well failures database developed over the years. This database consists over 500 failures from a variety of different operators.

Viking’s vast experience with failure investigations provide critical lessons learned that are then incorporated into our FDI Risk Assessment and the well and completion designs.


The GATE Prho tool provides rate transient analysis (RTA), fracture performance and evaluation, and identifies potential risks, including suboptimal production, suboptimal gas lift injection rate, FDI/Frac-Hit Detection, corrosion, erosion, casing-tubing connection (hole), liquid loading and flow restriction.
