Seventh, natural gas plays are replete with plastic pipe. Such pipe as shown in Figure 17is used for many purposes such as;fresh water transmissionfrac water transmissiongas transmissionsurface water drainageFigure 17 – HDPE solid wall, PVC solid wall, and HPDE corrugated pipe (various sources).-21-
The pipe is generally HDPE or PVC and can be solid wall (for transmission) or corrugated withslots or holes (for drainage). Whatever the case, natural gas plays require the use of plastic pipein a major way.<strong>Opportunities</strong> at Temporary LocationsFirst of all, temporary roadways of weeks or months are necessary in connection withsetup and eventual demobilization at natural gas plays. The geosynthetics industry has thecapability of providing wearing surfaces placed directly on the ground. Shown in Figure 18 arelight and heavy roadway systems developed by the Dutch Military for rapid deployment of heavyvehicles and equipment. They are typically 60 ft. long and 10 ft. wide and the weight varies withtype. Obviously, they can be redeployed as often as necessary.Secondly, temporary dams may be used for surface water control or for accidental spillsassociated with the drilling or containment operations. Figure 19 shows that geomembranes canreadily provide such temporary containment and be adaptable to myriad applications.Third, on sloping surfaces soil erosion is a concern and must be avoided so as to preventsilting of off-site areas and local streams and rivers. Geotextile silt fences have played aneconomical role in this regard for decades. Figure 20 shows such a silt fence being installed andproperly functioning.Fourth, rather than containing the site’s erosion after it occurs it is better to control andstabilize it before it starts. This has been traditionally provided by geosynthetic-erosion controlmaterials of which there are a great variety. The two major categories are shown in Figure 21 forslopes and channels/ditches, respectively. Designs are well advanced in both cases.-22-
