Continuous capillary injection surfactant selection/testing

29 July 2019 Folks,

We have some depleted gas condensate wells that are starting to get close to critical rate and suffering from liquid loading issues.

We have recently undertaken various simulations on options to extend production life.
Workover and recompletion is not commerically viable, and results of CT velocity string simulations were less than encouraging given limited life expectancy vs installation cost and complexity.

We are now moving towards foam assist lift via capillary injection as a more viable medium term solution, and have various Cap string installation options under evaluation currently.

Where I am struggling however is with the identification of suitable chemical vendors with proven Cap string surfactant experience in the region.

We are looking for companies that have the capability to undertake comprehensive testing and selection process and understand the particular issues that we face (offshore, hot, deep, high CO2, mix of water and condensate to lift etc etc) and how to replicate these in testing/selection process and also support during field testing/optimisation. 

Anyone got any experience with companies here in the UAE/middle east that have requisite experience and may be able to support?

Thanks in advance!
