About Geomechanics

Geomechanics software provides User to predict the well mechanical behavior before-, while- and after drilling.
Geomechanics software includes all necessary tools for the following tasks:

• Drilling risks reduction due to a reliable evaluation of the safe mud weight window, including wellbore instability intervals, AHRP, mud loss, etc.
• Drilling problems prediction as an oil and gas showing, blow out, sticking, collapsing, sand production, overpull, landing of drilling bit, etc.
• Well design optimization and correction of casing shoes depth landing
• Optimal direction and angle of drilling determination
• Real-time drilling support to increase rate of penetration, minimize downtime and inefficient construction costs
• Optimization of hydraulic fracturing design
• Critically stressed fractures identification
• Sand production and mud loss prediction in terms of wellbore stability influence to drawdown

Input Data

Geomechanics software allows User to download and analyze all data that required for geomechanical modeling.

The LAS bootloader allows batch input of information with the specification of several criteria (certain logging methods, selected depths and wells).

Stratigraphy columns data, core analysis tables, well tests, lithology columns, mechanical facies, drilling complications are conveniently inputted through the clipboard using the most common office software. The supported formats are LAS, DLIS, CSV, XML, TXT.

Data Analysis

Geomechanics software has a complete set of utilities that allow User to properly prepare various data before Geomechanical modeling:

• Logging data merging, matching, smoothing
• Petrophysical rock characteristics calculation
• Logging data synthesis with using of the most extended methods (Gardner-Castagna's, Han's, Faust's, Zalyaev's)
• Convertation of wave velocities data to slowness and backwards
• The scripts are based on C# machine language. The script allows to create own wizards in Project with using constants, arrays, rules, etc.

The next tools are using for vizualization of all data types:

• Well sections for displaying of logging data, well testing data, casing, stratigraphy and lithology column.
• Cross-plots for constructing various dependency graphs (as types as Core-Core, Core-Log, etc.), obtaining trend lines and correlation coefficients
• Multiwell correlations for selection of stratigraphy, lithology, geomechanical boundaries and picking on the polygon

1D-Geomechanics Model

The Geomechanics software allows User to obtain the following results in the simulation:

Geological Risks Analysis

Taking into account drilling problems, it allows User to assess the origin of geological risks and correct the geomechanical model.
Modeling in Geomechanics software allows User to minimize the possible risks associated with:

• Wellbore instability
• Determining the depths of landing shoes casing columns
• The ES on the site (oil and gas showing, blow out, sticking, collapsing, etc.)

Multi-Well Mode

Multi-well mode makes it easier to work with large amount of data. Geomechanics software provides functionality for the automated calculation of 1D-geomechanical models based on the User-planned Scenario (Workflow).
