PerfAct® Completion Engine – Optimizing Frac Efficiency and Performance
The PerfAct engine uses the accuracy of RockMSE derived from the OmniLog process providing a unique, reliable measurement that is a close proxy for unconfined compressive strength (UCS). This produces observable insights of the near wellbore rock properties that impact fracture efficiency and performance.
The PerfAct engine uses an automated, computation workflow that combines the gamma ray (GR), mud log, OmniLog outputs, geosteering, and other pertinent datasets when available, to give a modified completion design in a lateral that is optimized using all available measurements.
This enables optimized stage design and frac performance in an existing completion design, in order to achieve a client’s design objectives. Important considerations such as perforation phasing, induced stress, and perforation friction are embedded in the PerfAct engine.
Fluid Distribution Model in PerfAct Engine
A standard deliverable with every PerfAct job are fluid distribution models that are based on the interaction between perforation design and near-wellbore heterogeneity. These models use the OmniLog lateral profile (generated from common drilling data) combined with standard limited entry equations and first principle fluid dynamic calculations to estimate the relative amounts of fluids that enter each cluster within the lateral. These fluid distribution models allow our clients to quickly explore different completion designs such as number of clusters, perforation diameter, number of perfs per cluster, and cluster location to minimize over-stimulated and under-stimulated clusters.
The images below show the fluid distribution model of two scenarios in the same well – one completed with geometric configuration and one optimized based on rock properties:
- Identify like rock, for placing perforations in the optimal position for the most efficient fracs.
- Optimize base fracturing plan based on multi-variate analysis and treatment preferences.
- Optimizes diversion by modeling well heterogeneity with diverter analysis.
- Recognized by World Oil as the most outstanding completions technology in 2018.
- Performing “lookback” analyses of wells using available drilling and completion data.
- Optimize frac performance by understanding the effect of changing parameters and treatments.
