Sites preparation

Once the objectives of the well are clear, further decisions have to be made. One decision will be where to site the drilling location relative to the subsurface target and which type of rig to use. 

If no prior drilling activities have been recently carried out in the area, usually an environmental impact assessment (EIA) will be carried out as a first step. An EIA is usually undertaken to  

A site survey will be carried out, from which a number of parameters can be established, e.g. carrying capacity of the soil at the planned location, possible access routes, surface restrictions like built-up areas, lakes, nature reserves, the general topography, possible water supplies. The survey will allow the adequate preparation of the future location. For instance, onshore in a swamp area the soil needs to be covered with support mats. 

The size of the rig site will depend on operational requirements and possible constraints imposed by the particular location. It will be determined by  

A land rig can weigh over 200 tons and is transported in smaller loads to be assembled on site.

Equipment and Economics A veiy large electrodialysis plant would produce 500 /s of desalted water. A rather typical plant was built in 1993 to process 4700 mVday (54.4 /s). Capital costs for this plant, running on low-salinity brackish feed were 1,210,000 for all the process equipment, including pumps, membranes, instrumentation, and so on. Building and site preparation cost an additional 600,000. The building footprint is 300 itt. For plants above a threshold level of about 40 m Vday, process-equipment costs usually scale at around the 0.7 power, not too different from other process eqiiip-ment. On this basis, process equipment (excluding the ouilding) for a 2000 mVday plant would have a 1993 predicted cost of 665,000. 

Design and Operation ImpoiTant consideration in the design and operation of landfarming systems include (1) site selection, (2) site preparation, (3) waste charac tei istics, (4) method of waste application, (5) waste-application rate, (6) site management, and (7) monitoring. Important factors related to these design and operation considerations are reported in Table 25-75.

Site preparation and soil analysis are very important for grassroots plant estimating. If the stage of the project is such that no site has been selected, a generous allowance for site preparation should be included. Once the site has been selected, this phase of the estimate should be firmed at once. If soil conditions are less than ideal, an estimate of the added cost for piling, compacting, or whatever the soil conditions require must be included.

Time and effort must be spent in preparing a site for the cleanup activity to ensure that response operations go smoothly and that worker safety is protected. Site preparation can be as hazardous as site cleanup. Therefore, safety measures should be afforded the same level of care at this stage as during actual cleanup. Table 16.11 presents the major steps in site preparation prior to any cleanup activities.
