Upstream Technical Solutions
Petrophysical Services
OilNet offers a broad range of petrophysical services ranging from single well evaluations to fully integrated multi-well petrophysical studies, data room evaluations and equity determinations. Petrophysical services are either provided to customers as standalone studies or designed to support multi-disciplinary studies. Combined with specialized and routine petrophysical studies, our team works with exploration and production (E&P) asset groups to extract the incremental recovery from existing properties.
We utilize an effective and proven method for developing a petrophysical model. We integrate geological facies with engineering petrophysical units, referred to as hydraulic units, and petrofacies with logs to support exploration efforts and maximize field understanding of pore and rock type distribution for optimal well placement and recovery.
The following petrophysical services can be offered as standalone, fully integrated service or tailored to suite our clients need:
- Log Evaluation
- Rock & Pore Typing
- Permeability Modeling
- Core-log Integration
- Saturation Height Modelling
- Pressure Data Analysis
- Borehole Image Analysis and Interpretation
- Thin-Bed Evaluation
- Wellbore Stability Analysis
- Monte Carlo Error Analysis
Geological Services
OilNet technical solutions group offers geological services that support E&P projects, from basin-scale to regional petroleum systems modeling and play fairway analysis. Our group of subject matter experts utilize E&P experience from years of working, and knowledge of geological formations including; clastics, carbonates, deep-water turbidites, shale tight oil and gas formations, to develop reservoir models that are used for better understanding of the subsurface.

Production Engineering
Identifying the mechanism behind field production decline is essential for proper diagnosis of field productivity issues and designing a remediation strategy that will boost oil and gas recovery. Our approach to production enhancement solutions is based on defining methodology to improve productivity. We believe that a productivity enhancement study cannot be effectively performed without proper reservoir description and characterization. Therefore, we follow a process which we refer to as a “Systems’ Approach” which entails:
⦁ Evaluation of the production potential of a well based on drilling and completions
⦁ Diagnostic methodology for the identification of productivity impairments/improvement
⦁ Systematic and tractable approach to identify and quantify the mechanism of near- wellbore formation damage. Specifically, the thermodynamic (pressure, temperature, composition, and CO2 content) at which impairment begins to occur, review of secondary recovery methods and effects on productivity
⦁ Inflow performance relationships to determine well potential based on geological and petrophysical controls
⦁ Vertical lift performance and optimization Surface facilities constraints
Our services include:
- Well performance optimization
- Flow assurance problems
- Gas lift optimization
- Production system optimization
- Artificial lift studies
- Reservoir optimization including water flooding
Integrated Reservoir Characterization
OilNet reservoir study group brings together multi-domain expertise in integrated reservoir characterization to help clients better understand their reservoirs and mitigate subsurface and operational uncertainties, thereby allocating capital and resources more efficiently. This is achieved by integrating geological, geophysical, petrophysical, and engineering information into an accessible platform where they can be used by the integrated team to create the most realistic geologic and simulation model.
An Integrated Project Management Approach (IPMA) is employed to ensure that the project deliverables are achieved while the professionals assigned by the clients to the project make their contribution and learn from working with our experienced Geoscientists and Engineers. At the outset we identify the project team along with a project manager and the task leaders within the team. Further, the resources are allocated such as to best impact the successful completion of the project within the time proposed. Once the client has approved the project, the project team will critically evaluate the available data to create a detailed work breakdown structure from which the detailed tasks and assignments are made.
Any static or simulation model requires an integrated reservoir characterization approach which comprises of a seismically generated structural framework for a geological architecture that governs the up-scaling of petrophysically derived reservoir properties through fluid volumes and flow units, in a manner that conforms to engineering performance of the reservoir (Paul Worthington, SPE 2002).
