Review of EGS and Related Technology – Status and Achievements Chapter 4 431 • In contrast to what happened at Rosemanowes – where stimulation almost always focused on the bottom of the wells – the upper zones at the Soultz project would stimulate readily when fresh water was used; while, with heavier brines, the lower zones would be stimulated. • While microseismic monitoring works well overall to map fractures, we still do not completely understand the relationship between mapped acoustic emissions events and fluid flow. • We can drill deep wells into hard crystalline rock, control their direction, and log them. • There are aspects of drilling these wells that still need work. Problems with hightemperature mud motors make directional control of deep, hightemperature wells difficult. • Nearwellbore pressure drop can have a significant impact on the overall pressure drop throughout the system. • There are several methods for reducing nearwellbore pressure drops such as acidizing, emplacing proppants, and stimulating with fracturing fluids. Further testing is needed to determine which of these is most beneficial. • Acidizing reduced the injection pressure for a given flow rate but the reason for this is not clear. • Injection testing shows a nearly linear correlation between wellhead pressure and injection rate. This is typical of flow in porous media in general, suggesting that there was an overall fracturing pattern, not separate discrete fractures. It also reinforces the suspicion that the permeability is not dependent on pressure. • While injecting at high pressures can increase flow rates during operation of the reservoir, it can also stimulate fracture growth. Another alternative to highpressure injection is pumping the production well. • Logging tools have temperature limits, and there is little incentive for oil and gas to raise these limits to very high temperatures.PDF Image | Review of EGS and Related Technology

Infinity Supercritical CO2 10 Liter Extractor Design and Worldwide Rights: The Infinity Supercritical 10L CO2 extractor is for botanical oil extraction, which is rich in terpenes and can produce shelf ready full spectrum oil. With over 5 years of development, this industry leader mature extractor machine has been sold since 2015 and is part of many profitable businesses. The process can also be used for electrowinning, e-waste recycling, and lithium battery recycling, gold mining electronic wastes, precious metals. CO2 can also be used in a reverse fuel cell with nafion to make a gas-to-liquids fuel, such as methanol, ethanol and butanol or ethylene. Supercritical CO2 has also been used for treating nafion to make it more effective catalyst. This NFT is for the purchase of worldwide rights which includes the design. More Info
