Well Liquid Loading 2

[Morph711]

Hi Folks,

We have a well that has liquid loaded, that is foamed and eventually on the 6th attempt will flow. Except recently we cannot get the well on. The process is to open the choke sharply to 100% with a CITHP pressure of 80bar, the well will produce some gas, but drop off after 20min, where the temp will rise to 40C and then drop off. The back pressure from the manifold is 10bar, cannot reduce this with the compressors.

Suggestions are to try and open the well slower perhaps 30% for 10mins and see what happens. We have no gas lift and no means to flow in a smaller pipeline size or vessel to create a mist flow.

We are talking about N2 bullheading,but that will need further evaluation. Any of you good folk have any other suggestions, perhaps flowing the well in our test manifold, slightly smaller bore, but could cause issues in our test sep.

Sounds like you need an ESP....

Whats BHP readings?
Water cut / GCR over time?
Gas well or oil well?

What does the flow / pressure graph look like?

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

I think you need to pump the liquids out.

Answer the previous questions and provide formation depth, permeability/porosity, shut-in formation pressure, recent production history, last drawdown test data, well completion and profile details and oil's API.

--Einstein gave the same test to students every year. When asked why he would do something like that, "Because the answers had changed."

Thanks for the replies. I will get the information from the Production Reservoir Engineer.[pre][/pre]
