Hi guys,

I am new to Olga user, I need basic level help and will really appreciate for quick support.

I was running slug tracking enabled simulation and want to know.

How to interpret total slug volume out of simulation to size the slug catcher?  How to interpret slug length, no. of slugs and other outputs to total slug volumes for slug catcher sizing?

What drain rate should be considered for slug volume calculations?

What is basic purpose to enable water options under FA mode in Olga?

How to enter water cut present in feed stream into Olga inputs?

 

Regards,

MT

My suggestion is that you hire someone with experience to design your system.

MTQ80,
 
OLGA is a very good software for multi-phase pipeline transient analysis and specifically for scenarios such as slugging and hydrate formation. The slug volumes predicted by OLGA are quite accurate for sizing of slug catchers.
 
However, the problem with OLGA is that it is not the most user friendly software. Also when pipeline profiles are complicated (many undulations in the pipeline profile) it takes a hell lot of time to converge, sometimes weeks. Right now I am facing the same problem for a complicated pipeline profile and network where the OLGA run has not converged for days together and it is becoming a major problem to run the many cases that we have defined.
 
If you are a beginner in OLGA, I am sorry to say but it is way beyond a beginner to comprehend the complexities of OLGA. You should get in touch with SPT technologies (now Schlumberger) to either enroll for a training course or seek their direct help for solving an OLGA simulation exercise. 
 
Regards,
Ankur.

Hello Ankur Sir, 

 

Have you got OLGA tutorials ?

 

Thanks in advance

Zorro2107², and everyone else:

 

The company SPT Group owns the rights to Oil and Gas Simulator (OLGA).  The tool has been under continuous and still ongoing development, among others in the HORIZON II project where IFE and SPT Group are partners.  OLGA has a global market share of about 90%.  The technology is regarded as a central success for Norwegian petroleum research.  OLGA has enabled the development of oil and gas fields at deeper seas and farther from shore than would otherwise be possible without this technology, for example the fields Troll, Ormen Lange, and Snøhvit.

 

If you own a licensed, legal copy of the software and you need help or a “tutorial”, then contact the SPT Group.

 

If you don’t have a licensed copy of OLGA and you want to learn about it, contact the SPT Group.
