Firmus Process For Solid Drilling Waste

Our Firmus process for solid drilling waste is considered a viable recycling option under the EPA and API waste hierarchy.  Based on accepted solidification and stabilization technology, this service includes the engineering for waste disposition and pit closure, the work to recycle the waste, and the confirmatory testing of the recycled material after placement.

This proprietary process was developed by Scott over several years, for use on freshwater mud and cuttings, oil-based cuttings, and some saltwater mud and cuttings.  The process treats drilling waste so that it can be reused as construction material for lease roads, drilling pads, compressor station pads, tank battery berms, and other load-bearing structures.  The service is typically broken down into two phases:


1 Firmus Pre-stabilization
This phase is designed to reduce the plasticity, dry, and prepare the mud and cuttings for reuse. The resulting material is then transported to the location of the structure to be constructed.


2 Firmus Construction
This phase includes further stabilization and shaping of the material into a monolith to meet the desired loads that will be placed on it. Also during this phase, final samples are taken for confirmation of meeting the closure criteria.

From past experience, we have learned that the Firmus process is most effective when one or more of the following is present:

  • A customer has high contaminant levels
  • Transports the waste offsite for disposal
  • Has multiple wells to drill in a given area
  • Has high construction costs (drill pads that are placed in problematic, unstable locations and lease roads that serve multiple wells)

 

The benefits of the Firmus process are that it takes waste that is otherwise disposed onsite or offsite and recycles the material for the creation of structures that would otherwise need new raw materials to build. The Firmus process also reduces the customers’ environmental footprint and can help mitigate the customers’ future liability.

Firmus is a great way to reduce waste disposal cost, and to cut pad or road construction and maintenance cost.
