PFAS RochMech Tools is an add-on to PFAS. For a period, this
tool will be available for all users of PFAS Standard and PFAS Plus.
Beta version of PFAS RockMech Tools is planned to be released
in February 2004.
Well Path Planner - Survey
We have included this module to enable simulation of various well
paths, to find the ideal inclination and azimuth to drill through
This module is used to to insert well geometry data, such as
placement of wellhead and target, build and drop rates and more. The
module performs all the necessary calculations.
The resulting survey can be used directly in PFAS.
Frac & Collapse extensions in RochMech Tools
Collapse - Multiple failure criteria
In the Fracture and Collapse calculation section of the RockMech Tools
edition, there will in now be some more failure criteria in addition
to Mohr Coulomb:
Hoek & Brown
Insert Maximum Allowable Breakout Angle (MABA)
In this way you can plan very critical drilling operations, like
drilling through depleted zones, because you will accept for example 60
degree breakout angle, thus accepting a certain amount of breakouts. Your
hole cleaning capacity will determine how much.
Additional Fracture model
The Breckles and van Eekelen model is added to the fracture
calculations. A preferred model by many rock mechanics.
This module is used to predict uncertainty in prognosis established in
PFAS. All types of data and other factors related to the prognosis
can be taken into consideration. Use sensitivity analysis to weight the
A good tool to persuade your management to collect more data for
