About the Company History highlights - founded and acquired first clients in 2005 - two large corporate license deals with Oil&Gas Majors (TNK-BP, GazpromNeft) in 2010 - entered 3-year global co-marketing, technology cooperation agreement with Intel in 2010 - received VC investment from Intel Capital in 2010 to expand operations in USA, - other clients include: LUKOIL, Rosneft, Gazprom, Sinopec Development center - 30 math, physics, software engineers based in Moscow, Russia Worldwide sales & marketing: - sales, engineering support team in Houston, USA (1980 Post Oak Blvd, Suite 2030)

Worldwide Client Support Supporting clients across the globe - with more than 200 active users worldwide, RFD provides comprehensive technical support for its clients in Russia's European, West & East Siberial regions (Saint Petersburg, Moscow, Tyumen, Kazan, Nizhnevartovsk, Irkutsk), Kazakhstan (Aktau), UAE (Dubai), China (Beijing), USA (Houston) - more then 10 fully documented training courses are available for all the expert levels - only in 2010 alone 15 training sessions were offered with more than 60 engineers trained Documentation - professional documentation is available: User's Manual provides info on approximations, algorithms, keywords (600 pages) User's Guide describes GUI, standard workflows (300 pages)

Key technological advantages

Interactive desktop supercomputer First parallel simulator supporting 3D monioring and User’s interactivity at runtime: - automatically accelerates simulations on any number of CPU cores available (3-10 times) - monitor all 3D dynamic reservoir & well data at runtime - add wells, patterns, re-start runs, generate forecasts interactively at runtime - pre-, post-processing, monitoring through one intuitive multiplatform GUI - runtime analytics, 3D streamlines, drainage matrix, waterflood and injection optimization - split full-field models into sectors, merge them back without using Petrel, Gocad, etc. World's fastest parallel simulations for HPC clusters: - industry first hybrid parallel solver combining shared memory algorithms inside cluster nodes (threads) and MPI synchronization between nodes - typical acceleration factors for 20 node cluster are 40-50 instead of 8-12 (any existing industry simulators) New technologies: hydraulic fractures for full-field (shale gas), nano-polymers, etc.

ROI. Major reasons to switch

Seamless support of the existing models - loads Eclipse-100 models directly, no need to convert formats (also Tempest MORE, STARS*) - the simulation results can be written as the industry standard binary files Zero Tax for parallel performance - the license price is per computer and doesn't depend on the number of CPUs, cores used - automatically turns 4,12-core computer (e.g. HP Z800) into desktop supercomputer - run existing models 3-10 times faster on existing hardware - run models with minimum or no upscaling on multicore desktops, HPC clusters Software for all model sizes, all levels of expertise - powerful 3D GUI allows to perform many operations interactively, no keywords typing - users enjoy run-time live results monitoring, 3D streamlines, interactive re-starts - 32, 64-bit Linux, Windows systems, runs models from 1 to 100 million active grid blocks

Case studies

TNK-BP - corporate server license, statistics show more than 150 users, 80/day on average - universal support for all the corporate - use parallel performance, - , built-in 3D streamlines analysis for waterflood, workovers, and sidetrack planning directly at the field production units of Samatlor field (special accelerated training was designed). Gazpromneft - 30 licenses for desktop supercomputing using HP Z800 (8 cores, 16 threads) - 5 licenses for full-field massive hydraulic fracture modeling at low perm Priobskoye field LUKOIL - evaluating hybrid tNavigator for its HPC cluster intended for giant Iraq fields modeling

Support of standard functionality

- multi-component, fully-implicit calculations - black oil, live oil, wet gas, compositional, thermal compositional (research versions) - corner point, general mesh formulation (NNC, LGR, faults, pinch, etc.) - multi-reservoir option, surface network option - BHP, THP well controls, controls by debits, group, field including surface - multiple filtration, PVT (including multibranching), equilibrium regions - 3-phase permeabilities (end-point scaling), gravitation, capillary effects - vertical, deviated, horizontal, multi-segmented wells, fractures - segmented well density model - aquifers (constant flux, Fetkovich, Carter Tracy) - tracers, (nano)polymer flooding, collectors with salt - 3D streamlines modeling, drainage matrix analysis, injection efficiency evaluation - local multipoint flux approximation

Interactive GUI + Parallel simulations

- multi-screen interface allows for live monitoring of any dynamic reservoir properties, well production data, 3D streamlines - access different layers of data, analytics using mouse - simulator automatically runs on all the computers cores (e.g. quad-core laptop)

Advanced fracture modeling

- the hydraulic fractures are simulated as a network of

that ensures correct physics behavior - special tNav keywords allow to add propant tables to simulated dependencies of fracture permeabilities as functions of pressure, accum. flux - simulation of dynamic fracture behavior auto opening of fractures at the injectors

Application for shale oil production at Eagle Ford shale

- Grid sizes:

dx = dy = 25m dz = 1m

- Avg Perm: ~20 nano Darcy

- BHP = 50 atm

- Oil: 1.2 cP

Wells and fracture configurations at Eagle Ford shale

- wells length: 2 km

- well-to-well: 800 m

- fractures: +/- 1m high random 100-200 m wide - microseismic data - fracture completion with chemicals

Benchmarking with other simulators

- many clients run very detailed internal evaluations, comparing typical industry standard simulators they already use and tNavigator, - according to our statistics approximately 300 models were checked against Eclipse-100 and about 150 against Tempest MORE, - overall, the consistency is found to be very good, no major problems found!
