Geosciences Consulting
Maximizing Oil & Gas Production Rates and Recovery
Assign your company's geosciences challenges to A&A, and let our integrated geophysical, petrophysical, geological, geostatistical, and geochemical consultants build the static and dynamic reservoir models your development decisions can stand on.
Avasthi & Associates, Inc. (A&A) is an independent petroleum engineering and geosciences consulting firm. A&A does not sell geosciences software licenses or data services — our only business is expert technical consulting, which means our geosciences recommendations are never influenced by a stake in any particular software vendor or technology.
Our professional geosciences consultants have extensive experience conducting integrated geosciences analysis of oil & gas reservoirs. They are expert users of industry-standard geosciences software, such as Petrel, Interactive Petrophysics (IP), PowerLog, SMT, ECLIPSE, Landmark, and OFM, and are available for:
• Developing 3-D static reservoir models suitable for dynamic reservoir modeling of future performance predictions under various operating scenarios
• Conducting sensitivity studies to determine the optimal reservoir exploitation scheme
Most of the geosciences consulting services we provide, around the world, are described below:
Integrated Geosciences Analysis
Our professional geosciences consultants have extensive experience conducting integrated geosciences analysis, and are available for interdisciplinary evaluation of oil & gas fields around the world.
Geophysical/seismic, petrophysical, geological, production, and engineering data are evaluated and interpreted in an internally consistent manner, to produce robust geologic models that:
• Expedite project completion
• Provide early identification of potential design constraints
• Optimize scope and cost
These models include identification and quantification of geologic risks, and are suitable for generating dynamic models and defining development and re-development scenarios.
Our geosciences consultants are well prepared to assist our clients, around the world, in developing static models of their oil & gas reservoirs, as well as in:
• Developing additional data-gathering recommendations
• Data interpretation
• Developing proposals for field development
• Mentoring and training clients' staff
Geophysical/Seismic Analysis
Our high-level, seasoned geophysical/seismic analysis consultants have decades of experience providing:
• Structural interpretation
• Time-to-depth conversion
• Seismic attribute analysis
• Correlation with reservoir properties
• Seismic inversion
• AVO (amplitude-versus-offset) analysis
• Seismic velocity model building
• Sub-salt pore-pressure estimation
From data-acquisition recommendations to integrated evaluation with petrophysical, geological, and engineering data, our geophysicists/seismic analysis consultants — working as part of our geosciences team — are well prepared to assist our clients in developing static models of their oil & gas reservoirs.
Petrophysical Analysis
Our high-level, seasoned petrophysical consultants have extensive experience conducting petrophysical analysis — using PowerLog, Interactive Petrophysics (IP), and other commonly used petrophysical analysis software — and are available for evaluation of all types of well logs, including Russian well logs.
In combination with core and production data, well logs are evaluated to determine:
• Reservoir and fluid properties
• Fluid types
• Fluid contacts
• Mineralogy
• Fracturing
From data-acquisition recommendations to integrated evaluation with geological, engineering, and production data, our petrophysical consultants — working as part of our geosciences team — are well prepared to assist our clients in developing static models of their oil & gas reservoirs.
Geological Analysis
Geological analysis can reduce risk and uncertainty in all phases of hydrocarbon exploration and production. Our high-level, seasoned geological consultants have extensive experience conducting geological analysis, and are available for:
• Integrating geophysical, petrophysical, and local/regional geological data; making interpretations; and developing robust 3-D geological models — using Petrel or other commonly used geomodeling software — suitable for export to dynamic simulation models (such as ECLIPSE) for calculating oil and gas in-place
• Identifying geological uncertainties
• Generating a full range of probabilistic volumetrics
• Recommendations for data acquisition and integrated evaluation with geophysical, petrophysical, engineering, and production data
Our geological consultants — working as part of our geosciences team — are ready and well prepared to assist our clients in developing static models of their oil & gas reservoirs.
Geostatistical Analysis
Our high-level, seasoned geostatistics consultants have extensive experience conducting geostatistical analysis, and are available for petrophysical data quality control and normalization.
Other skills of our geostatistics consultants include, but are not limited to:
• Seismic calibration
• Direct hydrocarbon indicator analysis
• Seismic modeling and inversion
• Geological and geostatistical modeling
• Production analysis
• Reservoir simulation
• Database management
Our geostatistical consultants — working as part of our geosciences team — are ready and well prepared to assist our clients in developing static models of their oil & gas reservoirs.
Geochemical Analysis
Our high-level, seasoned geochemical consultants have extensive experience conducting geochemical analysis of oil & gas fields.
From data-acquisition recommendations to integrated evaluation with geological, engineering, and production data, our geochemistry specialists/consultants — working as part of our geosciences team — are ready and well prepared to assist our clients on their projects around the world.
What A&A Delivers
A geosciences consulting engagement with the A&A Consulting Team is built around the practical decisions your company needs to make, including, but not limited to:
• An integrated, multi-disciplinary static reservoir model, ready for dynamic simulation
• Identification and quantification of key geologic and geophysical risks and uncertainties
• Data-acquisition recommendations to close critical gaps before further investment
• Proposals for field development or re-development, supported by a full range of probabilistic volumetrics
• Presentation-ready results, and mentoring/training for your company's technical staff
