Introduction: KOSUN’s professionally custom drilling waste management solution and equipment for Algeria customer meet drilling project requirement of cuttings discharge less than 5%. Site treatment effect of drilling waste management equipment rivals that of world famous brand products, which are highly recognized by the customer.

 

Background information: SONA TRACHSH is a large international petroleum company with oilfield exploration and development business covering all over the world. The company has always been using KOSUN solids control equipment. In March, 2014, SONA TRACHSH is launching new drilling operations in Northern Algeria and gets the information that drilling waste management of the EN46F drilling project is required to meet environmental protection requirements (oil based mud is used on the project), among which the first and foremost technical index, OOC (oil on cuttings) shall be lower than 5%.

Features & Benefits 
With rapid development of the industry nowadays, all customers demand better and lighter equipment with easier operation. Vertical centrifuge is specially designed for high cost oil based mud operation and mainly has the following three effects: 
1. Cost; 
2. Environmental protection; 
3. Drilling fluid saving. 
 
Main objectives for research and development of vertical centrifuge during equipment designing are to: 
1. Reduce waste generated; 
2. Improve separation efficiency and save cost and customer budge compared with common solids control equipment; 
3. Be easy for operation and maintenance, all parts can be accessible for cleaning and maintenance; 
4. Enhance safety of personnel operation.
