Research of Different Well-type's Drilling Cost in Beach and Offshore Oil-gas Field
Zhong Shui-qin · Natural Gas Technology · 2009
With special regional natures of beach and offshore area,well types of vertical well,directional drilling,horizontal well and extended reach well are usually adopted for oil and gas development in this area.Based on historical data of different well-type's drilling cost in other beach and offshore oil-gas fields' development,by means of hypothesis testing method used for mathematical statistics and methods of classification,the drilling cost forecasting model of different well-type's in beach and offshore oil-gas development is established.By applying this model,unit drilling cost of the four well types are forecasted respectively.
