Welcome to. Oil & Gas Consulting Company. 01 Left Section A wonderful serenity has taken possession of my entire soul.

SEISWELL is new innovative geosciences company The company was created in September 2021 with the rise of startups and local content promoted by the Algerian government The company strengthen its added value in the area of reservoir characterization by adapting a unique approach, called ‘SEISWELL Technology’, based on the concept of Tortuosity, which is considered as the Rock DNA This unique technology is distinguished by the low-down in project execution time without extra-required data other than seismic inversion and few well data for calibration Other areas of expertise include but not limited to: petrophysics, rock-physics, geomechanics, seismic interpretation, seismic inversion and quantitative reservoir evaluation Our know how deals with both conventional and unconventional reservoirs either clastic or carbonates The company possesses three international patents in the field of reservoir characterization.

We are a reservoir Consulting Services with a patented technology Covering : First Advanced well evaluation & re-evaluation in order to unleash true reservoir potential which will benefit the client on  Better Evaluation of SW Independently of Resistivity (Low Resistivity Pay)  True Lithology Identification ( Radioactive Sandstones, Passive Shales, Volcanic Intrusions…)  Better identification of Pay intervals (Recover By-passed Reservoirs)  Propose new perforation intervals  Optimized Net-Pay Calculation and Reserves Estimation  Better handling of reservoir stimulation trough geomechanical modeling  Landing Drain-Hole and Laterals trough sidetracking  Ranking of wells and selection of good candidates for stimulation Anticipate Drilling Problems trough wellbore stability and pre-drill geomechanics Secound is the seismic characterization in order to reduce reservoirs uncertainties which will benefit client on :  Expertise in seismic structural interpretation  Multi-Derived-Seismic-Reservoir-Properties for a wise multi-attribute interpretation  Lithology and fluid separation for accurate sweet-spot identification  Better identification of Reservoir Anomalies (Recover By-passed Reservoirs Zones)  Reservoir delineation and up-front well planning  A Robust deterministic approach in unconventional source rock reservoir characterization (Multi-stage Hydraulic fracturing placement)  A comprehensive full 3D seismic geomechanical workflow for reservoir stimulation and pre-drill wellbore stability (safest drilling trajectory) Last but not least is Optimization through a faster time to insight & decision which will benefit the client on :  Treat every single reservoir differently (adapt to challenges)  Recover full hydrocarbons potential in less time  Propose new Drain-holes from neighboring Dry-Wells  Optimized asset development with faster access to insight and decision  Help in promoting the national mining domain with a demonstrated value and return on Investment To summaries our Solution will be able to reduce uncertainties and risks which allow our client to operate safely,efficiently and optimized cost for the projet

We Propose Critical and unique Solution to Challenging Assets • Bybassed Low-Resistivity Low contrast reservoir Pay • Tight and Naturally Fractured Reservoirs • Carbonates Reservoirs • Heterogenous & Anisotropic Reservoirs

We cover full range of Geoscience training and coaching

Efficiency through Cost & Time optimization Increase Drilling Success rate Help in promoting the national mining domain (Deliver More Reservoir parameter in Less time) HSE Policy: Environment awareness & Safer operation (Predrill Abnormal Pore pressure prediction) Build Trusted Partnership.

Innovative and unique patented technology Founded on Tortuosity Parameter that allows: Extract reservoir architecture and converts the seismic trace to a pseudo-well Develop Calibrated multi-parameter / multi-attribute quantitative reservoir characterization workflows (large number of derived attributes) Reduce uncertainties and help to resolve complex reservoir challenges (Low Resistivity and Radioactive Pay, Heterogeneity, anisotropy and Tight reservoirs) for various geological environments ( Clastic, Carbonates and Unconventional) and fluid types Drastically decrease the Cost and time of execution and De-Risk exploration decisions (faster access to insight and rapid return on investment).
