Production Analysis/PDG (DDA II)
KAPPA courses | In-house training | Free training | Consulting

Schedule & booking

  • Modern production analysis (PA)
  • Managing and using permanent downhole gauges (PDG) data
  • Immediate return on investment with attendees able to perform commercial analysis upon completion of the course
The KAPPA production analysis / permanent downhole gauge (PA/PDG) course is designed to teach the generic methodology and the practice of production analysis (PA), in addition to the mechanics of Topaze NL software which is learned almost as a by-product. The emphasis is on a visual and conceptual approach to interpretation including only essential mathematics. Full theory, including formulae and derivations are provided, as well as the conceptual explanation of PA in the accompanying KAPPA dynamic data analysis (DDA) handbook provided to each attendee.
Field examples are used to illustrate each concept. The final afternoon is a workshop, to which participants are encouraged to bring their own data.

Dynamic Data Analysis (DDA)
The production analysis/permanent downhole gauge (PA/PDG) course is the second week of the two-week dynamic data analysis (DDA) course and can be taken as part of a continuous two-week session, or as a single standalone one-week course.
Pre-requisites to attend the course
You have attended the equivalent of our foundation pressure transient analysis course (DDA I). To check your current level please try the self assessment test.
Software usage
The use of the Ecrin DDA software suite including the PTA module (Saphir NL), the PA module (Topaze NL) and the PDG data management module (Diamant) will be taught as part of this course.

Course programme
Quick revision on analysis theory and concepts
As learnt in the FPTA (DDA I) course with particular reference to long term data and pseudo steady state conditions typically found in PA cases.
Using numerical models
Building a complex numerical model for use in PTA and PA including irregular shapes, with multiple wells, compartments and geological discontinuities and heterogeneity.
Production Analysis
After a brief historical overview from empirical methods to modern plots, the application with field data of the principal techniques: Arps, Fetkovich, Blasingame, loglog, material balance, Pavg/Z, Pwf/z, P vs Q plots and history matching/forecasting.
Permanent downhole gauges
Handling very large datasets, wavelet filtering, working with incomplete and unplanned shut-ins. Processing multiple buildups and monitoring changing parameters, such as skin, with time. Setting up persistent links to data sources, issues and pitfalls, Specifying data requirements.
Field example
Working on a library of data from permanent gauges facilitating the analysis of multiple build-ups, single build-ups and production profiles. Other single profiles using surface recording or intermittent data will be analysed. PA and PTA examples will be handled analytically and numerically as applicable.
Workshop session
The final afternoon is an opportunity to work with real data provided by attendees or specific cases from the extensive KAPPA example catalogue.
