Abstract
This paper presents the well clean-up experiences for the Kristin HPHT gas-condensate field. The paper covers the production clean-up campaign design, including up front planning, job design, technology selection and review of the test results vs. the objectives. The paper also addresses requirements for safety and environmental considerations.
Traditional production clean-up methods and equipment has evolved over the years, adapting to changing authority and operator requirements, whilst striving to be more cost effective when it comes to operational cost, particularly in NPT terms. This has resulted in more complex equipment packages and much stricter environmental and safety requirements.
This paper will demonstrate how the above was addressed for the Kristin field development project and how the results compared with the set goals. Descriptions of the key design criteria and technology selection for HPHT gas-condensate well clean-up is covered together with the evolvement of these over time through the well clean-up campaign.
