What NSI Technologies does
NSI Technologies is a privately held Tulsa, Oklahoma-based software and engineering services company founded in 1984 that specializes in hydraulic fracturing design, analysis, and optimization for the petroleum industry. Its flagship product, StimPlan, is a proprietary software platform that uses 3D finite element simulation, Discrete Fracture Network modeling, stress shadow calculation, and integrated reservoir simulation to predict fracture geometry and optimize treatment schedules for shale, tight gas, carbonate, and conventional reservoirs. The platform is delivered as StimPlan V8 (with a cloud subscription option), supplemented by specialized modules — StimPlan Shale, E-StimPlan, an Acid Fracturing Module, a Frac-Pack Module, and a Numerical Reservoir Simulator — that integrate with downstream tools such as CMG, Halliburton QuikLook, and REXCEL/SENSOR.
The company monetizes through a combination of software subscriptions and licenses (StimPlan cloud and on-premise), professional engineering services (fracture design, look-back studies, microseismic analysis, geothermal support), and recurring industry training courses delivered in-person in Houston and Calgary and online. NSI emphasizes its independence — it does not sell pressure pumping services or stimulation equipment — positioning itself as an unbiased third-party advisor to operators, with named enterprise customers including Chevron and Saudi Aramco and operations extending into Brazil, China, Canada, Saudi Arabia, and Norway. Beyond software and services, NSI operates the Wed(NSI)Days weekly webinar series and the PEER Consortium, a multi-company research initiative on perforation erosion launched in February 2022.

NSI Technologies product offering
Product offeringCore offering
NSI Technologies develops and sells StimPlan, an integrated software solution for hydraulic fracture design, analysis, and optimization, using rigorous 3D finite element simulation. The company complements the software with professional engineering services (fracture design, look-back studies, microseismic analysis, geothermal support) and industry training courses in hydraulic fracturing, DFIT analysis, acid fracturing, and rock mechanics. Customers include oil and gas operators developing unconventional shale, tight gas, and carbonate reservoirs.
Product overview
NSI Technologies offers StimPlan, a comprehensive hydraulic fracturing engineering software solution with multiple modules. The core product, StimPlan V8, is a complete platform for fracture design, analysis, and optimization featuring fully 3D finite element simulation, cloud computing capability, and multi-cluster simulation for horizontal wells. Specialized capabilities include the StimPlan Shale module for unconventional reservoirs (with DFN modeling and microseismic integration), the Acid Fracturing Module for carbonate reservoirs, the Frac-Pack Module for sand control completions, and an integrated Numerical Reservoir Simulator for production forecasting. The company provides engineering consulting services (fracture design, look-back studies, microseismic analysis, geothermal support), industry training courses (hydraulic fracturing, DFIT analysis, rock mechanics), hosts the Wed(NSI)Days weekly webinar series, and leads the PEER Consortium for perforation erosion research. V8 Cloud subscriptions enable cloud-based parallel simulations.

NSI Technologies competitors and assessment
Company assessmentDirect peers
- ResFrac: ResFrac is a direct competitor offering a 3D hydraulic fracture and reservoir simulator used by operators for unconventional completion design. It targets the same petroleum engineer buyer with a cloud-native, fully 3D finite element/finite volume approach, making it the closest functional analog to StimPlan.
- Itasca (FracMan): Itasca's FracMan is a long-standing discrete fracture network (DFN) and hydraulic fracturing simulator widely used by operators and consulting firms. Its DFN and stress-shadowing capabilities overlap directly with NSI's StimPlan Shale module, making it a primary alternative for unconventional completions modeling.
- KAPPA Engineering: KAPPA provides pressure transient, production analysis, and fracture diagnosis software (Saphir, Topaze, Rubis) widely used alongside fracture design tools. It competes with NSI in DFIT analysis and fracture pressure interpretation, targeting the same petroleum engineer workflow.
Broad incumbents
- Computer Modelling Group (CMG): CMG is an established reservoir simulation incumbent whose reservoir solvers integrate with NSI's fracture simulation outputs (per NSI's documented integration). It competes on the reservoir side of the coupled frac-to-production workflow and is a likely alternative or complement to StimPlan Reservoir.
- Petroleum Experts (Petex): Petex's integrated production and reservoir software suite (PROSPER, MBAL, GAP) overlaps with NSI's reservoir simulation and production forecasting capabilities. Petex is often on the operator's approved software list, making it a substitute for NSI Reservoir in production modeling workflows.
- SLB (formerly Schlumberger) — Petrel: SLB's Petrel platform includes fracture modeling modules (Visage, Mangrove) integrated into a full E&P subsurface suite. SLB competes with NSI through bundled offerings and global enterprise reach, though its equipment/pumping ties reduce its independent-vendor appeal.
- Halliburton — Landmark DecisionSpace: Halliburton's Landmark DecisionSpace Geosciences and related completions software (including integration with QuikLook, which NSI explicitly outputs to) compete for the same operator IT budgets. Halliburton's integrated pumping and software portfolio gives it scale advantages NSI lacks.
- Baker Hughes — JewelSuite: Baker Hughes' JewelSuite Reservoir and Earth modeling software includes geomechanics and fracture simulation capabilities that overlap with StimPlan's 3D finite element workflows. As an integrated oilfield service vendor, Baker Hughes competes on enterprise platform breadth.
Regional players
- GaffneyCline: GaffneyCline is an upstream consulting and software advisory firm serving international operators, with overlapping technical consulting services in completions and reservoir engineering. It is more regional/advisory-focused but competes for similar engineering services budgets in markets outside NSI's core North American footprint.
Emerging players
- Geosteering & Reservoir Modeling Services (GeoRMS): Smaller specialized firms offering fracture modeling and consulting services that compete with NSI's engineering services arm, particularly in regional markets or for boutique operators that do not license StimPlan directly.
