Site Selection, Layout, and Spacing

From the perspective of process safety, key considerations with respect to site selection, layout, and spacing can be summarized as... 

The rig selection will dictate the basic layout of the pad. Based on the necessary area needed to support its functions, ancillary equipment may be added in space conservative measures. In addition to the placement of various stationary rig site components, other operations such as logging, trucking and subsequent completion operations must be provided for. The most environmentally sensitive design will impact the least amount of area, and in that it will be the most economic. Potential pad sites and access routes should be laid out on a topographic map prior to the actual survey. At this time, construction costs can be estimated and compared. Figure 4484 shows such a layout. The cost of building a location includes the cost of reclamation such as any remediation. 

Selection of tertiary containment options will be highly dependent on site-specific factors such as layout, topography and available space. The term transfer systems (CIRIA 164 3 chapter 13) is used to describe the means for collecting and conveying spillage/firewater to remote and combined...
