Yes you are right there is no an easy solution to overcome this issue and now its under study to evaluate the options stated above or to start trucking. thanks for your valuable comments .
its light crude so the main reason for back pressure is gelling but you are right waxing issue is also factor that we need to considered in FA, actually we don't find software simulating the gelling issues. batching with water is an option but the pipeline designed to handle processed crude so...
Thanks LittleInch
yes pipeline rated to 100 bar and now the operating pressure is only 10 bar, the ten options you stated we already sort it and i will state our point of view for each one as follow:
1) Yes raise pressure to combat the increased viscosity of the pipe (1st ranking option we...
Thanks MortenA for your reply actually we checked the PP recently and as you said it was changed from 33 to 36. and as you said using PP depressant is not economically feasible with the current low production and high OPEX so we try to find another less cost and permanent solution for this back...
Hi All
we have 12” pipeline , 44km long at 75c exporting temp the initial production is 10000 BOPD, (70m3/hr). now the production decline to 2000 BOPD which has raised flow assurance risks in view of the low flow (pipeline minimum flow rate) which associated with the crude gelling (pp =36c) ...
