1.3.3. MEDCO-FACT-Software
Fatigue Analysis for Coiled Tubing
FACT is a management tool that can be used to maximise the safe use of coiled
tubing strings. The Fatigue Analysis, tracks life consumption of individual coiled
tubing strings and parts of the strings subject to jobs carried out in wells or in the
yard, and showing life consumption per job.
In addition, the module gives the user the option of finding the maximum number of
cycles to fatigue failure, with or without internal pressure and subject to a user
specified geometry of the goose-neck and the reel.
In all the computations of this module, corrosion factors (due to acid, cement, etc.)
and stress concentration factors (due to welds) are taken into account.
There are two modes of operation of the program, as a stand-alone program where
data can be entered manually, or can be used in real-time reading data directly from
a data-logging program such as DART producing up-to-date state of the pipe as well
as the real-time tri-axial stresses.
At any time, the user can view the current status of the coiled tubing or can review
the history of the string.
A database of the most common coiled tubing sizes and materials currently produced
by the manufacturers is included. In addition, a database of most common corrosion
factors and stress concentrations due to welds are also included. The user is also
able to add new records to the supplied databases.
1.3.4. MEDCO-TAS-Software
Tubing Analysis System
TAS is a computer program designed to perform various calculations and simulations
often needed in tubular applications. TAS is used as a coiled tubing job simulator.
TAS is an integrated modular program incorporating Force and Stress Analysis, Fluid
Circulation, and Transient Simulator, in addition to numerous quick computations
often needed in tubular computations.
Force and Stress Analysis Module
The computations in this module include the effects of weight, friction, buoyancy,
well head pressure, pressure drop through downhole tools, dog-leg severity, and
extra friction (in buckling modes, i.e. sinusoidal and helical).
The module will automatically detect critical conditions such as lockup and severe
dog-legs. Furthermore, several options are available for simulating different
scenarios such as applying weight-on-bit, bottom-hole pull, changing well
conditions to account for fluid circulation effects, predicting maximum pull, and
predicting maximum push to lockup.
