Although the oil and gas industry has a good environmental spill record, sometimes a spill of condensate occurs on oil and gas leases, flowlines/pipelines, gas plants and other sites. Due to the different characteristics of condensate, when compared to crude oil, the remediation of these spill sites varies. Many of the typical options in use today are soil removal, soil venting, soil farming, bioremediation, and thermal-desorption. The challenge for the environmental and operations managers is to select the best system for the each particular site.

Costs and liability for off-site disposal and potential groundwater contamination are ever increasing. Kerr-McGee conducted a study of passive and mechanized soil venting of condensate contaminated soils in the panhandle area of Texas. Both systems proved to be practical and effective.

Goals of the project were to:

  1. Remediate the contaminated soils to the Railroad Commission of Texas limits.

  2. Determine the effectiveness of both systems.

  3. Remove the possibility of any groundwater contamination by remediation of the soil profile.

All three goals were met and this paper summarizes the results of this project and provides another tool for remediating condensate-contaminated soils.
