FEESA Limited - Flow assurance and optimisation of Oil and Gas Systems

FEESA have recently attended the MPT Multiphase Production Technology annual conference in Cannes, where Dr Martin Watson presented an approved paper, entitled "Application of advanced chemical process design methods to integrated production modelling" by M.J. Watson, N.J. Hawkes and E. Luna-Ortiz

FEESA were represented by Dr Marco Montini and Adrian Johnson at the 7th International Conference on Gas Hydrates in July, where they presented a paper to well over 400 personnel from industry and academia.

Copies of the paper entitled "A probabilistic approach to prevent the formation of hydrates in gas production systems" by Marco Montini, Andrew I. Humphrey, Martin J. Watson and Adrian E. Johnson

Both papers can be supplied on request to Info@FEESA.net

FEESA visited the OAG Malaysian Oil and Gas conference in July, and a series of visits and roadshows to Houston, Abu Dhabi, Muscat,Doha and Kuwait to continue the promotion and expansion of Maximus in the Gulf of Mexico and the Arabian Gulf regions. FEESA will shortly announce a selection of qualified partners and representatives in these regions.

OLGAS Multi-Thread Type Implementation Speed-Ups

SPT's steady state OLGA™ model (OLGAS™) has been available in Maximus for some time, but many users found OLGAS slowed down their Maximus models too much to be of practical use, particularly on life of field simulations of huge gas networks, so they resorted to using one of the published mechanistic models.

The published mechanistic models are not particularly faster than OLGAS, however they are multithreaded in Maximus, i.e. they can use all the processors available on a computer, whereas OLGAS is not multithreaded and so only one OLGAS pipeline or well could be integrated at a time, creating a bottleneck.

In response to users, Maximus programmers have worked on this OLGAS time penalty and, in negotiation with SPT, have come up with a workaround to allow OLGAS 2 and 3 phase to run as though it were multithreaded. As a result, models of large networks with OLGAS have increased in speed by between 3 to 5 times, depending on their complexity. This opens up the possibility of using OLGAS on larger, more complex networks such as life of field LNG, tight and shale gas network studies.
