he objective of this document is to give a quick yet exhaustive overview of the v4.12
additions. Items have been split into the following categories: Analysis – Saphir – Topaze –
Diamant – Rubis – Generic. The format is deliberately concise. For more detailed information,

Amethyste: Well Performance Analysis

Ecrin v4.12 includes major additions to existing modules but Ecrin v4.12 also
integrates a whole new module for Well performance Analysis called Amethyste. If
you are using any KAPPA product, you have access to Amethyste until April 2010.
With Amethyste in Ecrin, any module may now run a complex wellbore model
dynamically. You can refer to the Amethyste white pages on the Ecrin v4.12
download page for more details.
.Numerical
– Unconsolidated in multiphase (NL)
– Desorption in gas or gas-water using Langmuir isotherm model to address shale gas and
coalbed methane situations; saturated or undersaturated (NL and Rubis)
– Desorption with diffusion in the coal matrix (NL and Rubis)
– Desorption combined with unconsolidation (NL)
– Fractured horizontal well
– ‘Stadium’ composite region for horizontal and fractured wells
New structure
The Topaze document structure was changed to allow the multiwell mode. The changes have
brought the following enhancements:
‐ PVT in the analysis – Distinct reference wells in different analyses – Reference well and PVT
can be changed after creation – Any rate can be loaded (no init checkboxes)

Plots
‐ ‘Flowing material balance’ plot
‐ Multiwell option in BTC, p-q, q-Q plots
‐ Generate model from all relevant diagnostic plots
‐ King p/z* analysis for CB
