This paper describes the flow assurance and production chemistry test program implemented during the exploration and appraisal (E&A) phase of a new development area offshore Vietnam. The impact of the program on the facility design is described and program results are compared to operating experience. Fluid samples from several E&A wells were sent to the ConocoPhillips Production Assurance Technology Group in Bartlesville, Oklahoma for analysis. The analytical program consisted of the following groups of tests:

General Properties: API gravity, sulfur content and total acid number (TAN). 
Separation Properties: Emulsion and foaming characteristics and asphaltene deposition tendencies 
Flow Assurance: Viscosity, pour point, paraffin content/distribution, wax appearance temperature (WAT), wax deposition rate and gel strength.

The flow assurance test results had several positive impacts on facility and infrastructure design. Coordination between the Project Team, Operations and the Production Assurance Technology group led to significant insights which improved the facility design and operating procedures.
