These failures, which included the fractured face of each of the parted components, were analyzed and evaluated (Fig. 1). The slanted fracture indicated...

...Trent Jacobs Drill a well. Induce a fracture. Pump water. Start flowback. This sounds like the steps used to bring to life tens of thousands of tight-oil and gas wells over the past quarter century. But what it really describes is the emerging approach that a pair of Houston-based companies...

.... A commercial simulator is used to build a typical horizontal hydraulically fractured well. The outputs from the simulator are time series of oil-, water-, and gasproduction responses. All formation parameters are assumed to have a normal distribution. The description of various formation properties used...

... with evaluation of stress and expected fracture orientation. With this information, an FH pathway can be inferred between the infill and the parent wellbore. Collating this information assists in the generation of a map that captures all FH events with the extension of this analysis to all stages and parent wells...

...Stephen Rassenfoss Fervo Energy has shown that fracturing can be used to build a geothermal heating system in hot, hard rock. During a 37-day test at its Project Red test site, the Houston company produced as much as 63 L/s (998 gal/min) of water heated to 336°F. By pumping water from an injection...

... raised enough red flags for ExxonMobil to rethink its plans for a tight-well design. Multiple sources of data showed the wells were too close, their fracture networks in too much communication. “These results suggest the pilot location was overcapitalized and that future developments should be drilled...

...Zhiming Chen Fractures, whether natural or hydraulic, serve as crucial pathways for fluid flow within rock formations. Because natural and hydraulic fractures are generated hundreds of meters underground, their parameters always seem to be a black box. Their influence on pressure propagation...

...%) but higher than the Eagle Ford (between 8 and 10%). Significant formation thickness drove the application of vertical wells during the first factory drilling in Vaca Muerta. It allowed placement of four to six hydraulic fractures controlled by the lithologies and vertical heterogeneity. In 2015, however...

..., horizontal drilling and hydraulic fracturing were combined to extract hydrocarbons from unconventional shale resources, which helped us meet rising global oil demand. However, production from existing shale oil wells declines quickly, and ultimate recoveries are often less than 10%. To meet global demand, we...

.... EGS mostly involves well designs that rely on fractures for heat extraction. Such systems are different from CLGS wells in that the latter use closed conduits for thermal fluid circulation and heating. CLGS relies on fluids pumped through a closed loop. The authors treat CLGS systems as being...

...Stephen Rassenfoss Two test sites in the southwest US have successfully fractured geothermal injection wells in hot, dry hard-rock formations. Now it is time to find out if they can create really hot water by pumping cold water through the fractures in that hot rock into a second well. Both Fervo...
