WHAT WE DO
Three Pillars of Expertise
We bridge advanced, physics-based understanding with modern automation so operators can make faster, data-informed completion decisions.
Real-time analytics &
automation
Turn live frac data into automated, physics-based diagnostics and optimization insights while the job is still in progress.
Technology development & integration
Build intelligent, scalable platforms that improve operational efficiency and consistency across pads and assets.
PRODUCTS
Software Built from Real-World Engineering Practice
Our platforms codify workflows our team has refined in the field - so operators get consistent diagnostics without extra hardware or field staff.
WHY SSD
Integrated Expertise. Real-Time Insights.
We combine reservoir engineering, hydraulic fracture diagnostics, flowback analysis, and automation so operator's teams act on live context - not delayed reports.

TESTIMONIALS
What Our Clients Say
“I want to say how impressed we are with Real Time Frac Optimization (RTFO) platform and your team's responses to our requested changes. It really helped us understand and communicate operations to our stakeholders.”
Wes Hill
Team Lead - Completions
Vermilion Energy
“RTFO was a helpful addition for our first multi-well pad. It integrated seamlessly with multiple data sources to provide early insights into fracture geometry, stress shadowing and reservoir response.”
Greg Niebergall
VP of Exploration
Yoho Resources
“We were happy with the Flowback Data Analysis (FBA) results. I have used the results to calibrate RTA models, plus we can use the frac results for comparison with previous phases and help fine-tune our frac designs.”
Mike Miller, P.Eng.
Sr. Reservoir Engineer

Frequently Asked Questions
Quick answers about our platforms, workflows, and engineering services.
Subsurface Dynamics combines reservoir engineering, geoscience, hydraulic fracture diagnostics, and digital technology to help operators make faster, data-informed field development and completion decisions.
RTFO (Real-Time Frac Optimization) is our web-based platform that turns live frac treatment data into automated, physics-based diagnostics. Teams get stage-level insights on execution quality, interaction risk, and geometry while pumping - without extra equipment or field staff.
FBA uses flowing well pressures and production rates from short post-frac flow tests to estimate fracture and reservoir properties that drive long-term productivity - typically 6-12 months sooner than classical rate-transient analysis on long-term production data.
FBA can estimate hydraulic fracture properties (including mobile fracture volume, conductivity, and half-length), reservoir or SRV permeability, and support long-term production forecasts from early-time data with limited field cost.
No. We deliver multidisciplinary consulting - integrated studies, fracture modeling, reservoir characterization, seismic services, and technical due diligence - alongside technology products like RTFO and FBA that codify those engineering workflows.
