Comparative Analysis of Drilling Waste Disposal Method by Ogbeide, P. O. and Onaiwu, O. D.. Vol. 25 ( Nov. 2013). pp 177-182
Sale price: $5.00

 Biodegradation, Stabilization, Incineration (Burning) and re-injection methods of handling drilling wastes were investigated and the central objective is a comparative analysis of  drilling waste disposal methods, while the specific objective is to examine the various methods of managing drilling wastes and adapt the technique which is more effective and efficient.  

The re-injection method is chosen based on the fact that it gives permanent ‘elimination’ of the waste (s) from the environment.The stabilization method causes great corrosion to the adjacent properties (materials). The biodegradation was not chosen because of the disadvantages such as the presence of resins and asphaltenes, which are resistant to biodegradation and sometimes the environmental conditions may not be favorable for the micro-organism to act on the waste material(s).The incineration method causes atmospheric pollution and has a very short life span. The pre-treatment of the waste, such as flocculation, should be carried out before adopting the re-injection method.
