A properly designed diverter strategy can increase stage lengths as well as

increase fracture density and complexity. . .

The end result is better frac performance at a lower cost !

“We decided to use D2F Engineered Diversion Service on several wells in Eagle Ford and it executed perfectly with diverters
hitting targeted perforations as planned, producing expected pressure responses, zero screen outs, and pumping rates
according to schedule. Overall, we are very pleased with D2F’s services and their valuable impact on our fracture performance.”
-VP of Completions – Eagle Ford Operator

The Drill2Frac Engineered Diverter Solution estimates the stresses along the lateral. By knowing the stresses at each cluster, we can determine which clusters will break down and take fluid first, then design the completion in such a way that only those clusters take fluid initially, and that the secondary clusters do not break down during the initial pumping segment. Also, by knowing how many clusters will initially take fluid, we can determine how much diverter to use. Then we determine which clusters are likely to take fluid next and design for that.

To ensure that clusters are properly segregated into distinct pump segments, we use a multi-faceted approach which is grounded on a stage-by-stage pressure balance. This pressure balance ensures that clusters are only broken down and treated according to the design. This is done using multiple approaches including placing clusters in opposing stressed rocks, adjusting perforation design, adjusting pump rates, and inducing intrastage stress shadows.

Eagleford Case Study:

An Eagle Ford operator wanted to better understand their diversion results in order to improve cluster performance and reduce operational complexity prior to scaling up operations.

Post-job fracture treatment reports showed that 88% of the diversion drops in the D2F recommendation were successful. In contrast, the two offset wells averaged 64% effectiveness. Also, the number of screen-outs in the D2F well was just 1/3 of the number of screen-outs in each of the offset wells.

Wolfcamp Case Study:

A Wolfcamp operator was focused on reducing completion times without negatively impacting production. Post Frac results show that not only was the operator able to see a meaningful reduction in completion times but 90 day cumulative volumes showed a 4% increase in production.

Engineered Diversion Strategies answers the following questions:

1. How many diverter slugs are needed?

2. How much diverter should you use in each slug?

3. What is the best way to perforate?

Operating blindly (without knowing rock properties across the stage) can lead to the following undesirable conditions.

1. Blocking of perforations without diversion of fluid

2. Over pressure from too much diverter

3. Inadvertent creation of dominant fractures

The Drill2Frac Engineered Diverter Strategy service predicts pumping pressures and diverter pressure response.

That means you can plan your diverter strategy more effectively, and verify in real time that the strategy is effective.
