Optimising Fluid Choices for Landfarm Applications

A well established method for bioremediation of drilled<br>cuttings and adhering base fluids is the use of landfarming or<br>composting. All base fluids are amenable to this method.<br>However, degradation of organic materials takes place over<br>different timescales, and there is potential for toxic residues to<br>affect the future use of land to which cuttings have been<br>applied. This paper describes a project where a degradation of<br>a range of different commonly use base fluids was<br>investigated and the use of various commercial accelerants<br>was also tested to determine their impact on degradation rates.<br>It subsequently describes an investigation into plant and<br>animal toxicity of soils to which base fluids have been applied.
