234 Chapter 2 Geothermal ResourceBase Assessment 2.6.4 EGS in sedimentary basins beneath hydrocarbonbearing fields Table 2.4 Comparison of cost components for “EGS” development (previous model for geothermal development vs. reality in oil patch situations). Components of Direct • Drill wells that reach hot temperatures.>150°C (>300°F), EGS Development Cost • Fracture and/or horizontally drill wells to develop high water flow and/or acquire makeup water, • Install infrastructure, roads, piping, and power line routing, • Build power stations Actual Field Conditions • Many wells with BHTs of more than 150°C (300°F) at 4,570 m (15,000 ft) or less, • Wells fractured or horizontally drilled in many cases, • Water available from the well or adjoining wells in fields or as externally supplied disposal water (paid for by disposer), Another scenario exists for geothermal development in many of the areas exploited for deep oil and gas production, especially in the Gulf Coast and mountain states regions. In these areas, EGS development in the deep, hightemperature part of the sedimentary section might be more cost effective than basement EGS systems. Table 2.4 shows a comparison of needs for EGStype development costs vs. reality in existing hydrocarbon fields. It is clear that many of the upfront reservoir costs have been reduced, and that the existing infrastructure can be readily adapted to geothermal electrical power production. • Inplace infrastructure of power lines, roads, pipelines, • Continued production of gas and oil in otherwise marginally economic wells. Direct Costs to Develop a Gulf • Build power station, Coast EGS System • Recomplete wells, in some cases, and test flow system, • Minor surface infrastructure upgrades (i.e., insulating collection pipes, etc.) Future work must be performed on the suitability of some of the wells/fields now being developed as deep, hot, tight, sandstone gas reservoirs; but, overall, it appears that large areas of the United States are suitable for future geothermal exploitation in the near term that have not been considered in the past. Many of these areas are hot, and most are being artificially stimulated (fractured), or horizontally drilled, or both. These areas are clearly “EGS” types of systems but with known drilling and development costs and abundant water. Because of the thousands of wells drilled, the costs may be in some cases onehalf to onethird of those for hard rock drilling and fracturing. A failed well in oil and gas exploration often means too much associated water production. In some areas, such as the Wilcox trend in south Texas, there are massive, highporosity sands filled with water at high temperature. These situations make a natural segue way into largescale EGS development.PDF Image | Geothermal Resource Base Assessment
