Application on Heavy Oil Production with ALS - ESP

Home / Application areas / Experiences

Main Needs Identified

Identified needs for this application of additive in well with ALS – ESP

  • High viscosity of produced fluids and low volumetric efficiency of ESP
  • Well Heads over pressured
  • Oil dehydration and compatibility with the installed process
  • Retention time at production facilities
  • Organic material precipitation

Solution Proposal

Bottom Hole SF – FL Fluidifier Application Through Capillary Injection

Benefits from the bottom hole application

  • Viscosity reductions were higher than 50%.
  • Increase volumetric efficiency of the ALS – Higher subsurface pump performance – Higher Run Time.
  • Reductions in electric consumption associated with overpressure wellhead.
  • The lower injection rate of additive compared to diluents.

Solution Development at Laboratory

It was designed the need SF – FL product according to the properties of the DHA1 sample.
