Jeff Reddoch, Sr. CEO, was the founder, President and CEO of Apollo Services, Inc., a Registered Mechanical Engineer in the USA, was heavily involved in the design, planning, operational aspect and quality assurance.  Up until Mr. Reddoch left the company in 2002, he daily reviewed all CRI operational reports from around the world and made sure that all operations continued successfully. 

DRILL CUTTINGS REINJECTION

Down-hole cuttings injection (CRI) has come of age over the past 10 years and is considered a viable option for drilling operations.   Environmental regulations are based upon the cradle-to-grave concept, and thus the operator never relinquishes responsibility for the drill cuttings and the chemicals left on them.   Tightening of the allowable discharge limits, revocation of many once-accepted disposal methods of the past and the resulting major clean-up operations (even on the seabed), and the increasing cost of land fills/farms, have forced many operators into switching from short term planning to long range planning for drilling waste.  Additionally, in the North Sea, land for land farming is just not available and regulations do not normally allow for land farming.     

Many operators have acknowledged that the least expensive way to handle their drill cuttings waste is to handle waste only once.  Operators who have acknowledged this waste paradigm and have aggressively attacked the engineering concerns of CRI, are presently re-considering and implementing CRI as the way forward.     

CRI consists of a different set of parameters other than typical fracture models.  The fracture models for hydrocarbon stimulation are designed and noted as follows.
