What is Ava® Structure?

Software to optimise the structural modelling workflow

Reservoir compartmentalisation is a major uncertainty in the appraisal of petroleum reservoirs. Poorly understood reservoir compartments and the connections between them affect the volume of movable oil or gas in a given field and can have a serious impact on field viability and profitability. Ava Structure, a plugin for the Petrel* E&P software platform, allows you to assess the impact of fault connection uncertainty by generating alternative plausible fault networks in four intuitive and efficient steps.

Assess Interpretation Confidence

Using published structural geology rules, Ava Structure carries out multiple quality control operations directly on seismic interpretation data, providing a basis for interpretation confidence.

Define Connectivity Scenarios

Ava Structure’s unique throw extraction methodology generates throw profiles for each interpreted fault, used to estimate probabilistic fault tip extensions, objectively defining P10, P50 and P90 fault extension and connection cases.

Reliably Quantify Uncertainty

Ava Structure reports numerous diagnostics for each case, including number of fault blocks, fault block area or area connected to a well, as well as plotting the extracted throw data. Histograms provide connectivity distributions, allowing uncertainty to be reliably quantified and understood.

Address Structural Uncertainty

Stochastic realisations can be exported to Petrel and can be fed directly into structural modelling workflows, automating the grid building process and allowing compartmentalisation uncertainty to be routinely integrated into the reservoir modelling workflow.


Data Aware?

Ava Structure is data aware, which means that any change to a data item is flagged and recorded within the assessment card, allowing you to track your interpretation progress, quality and confidence through the workflow.



All your data is treated as confidential, remaining within the Petrel project and never taken to the cloud.



All assessment steps are recorded and saved within the Ava Structure data card. Updates and modifications to interpretations are flagged, providing a fully auditable trail of your interpretation progress, which can be exported as a PDF file.
