A controlled rate of propagation of the fluid saturation front or thermal front is desired in may oil and gas and geothermal operations. Natural fractures and fractures created during hydraulic stimulation may have heterogeneous hydraulic properties resulting in uneven flow distributions, therefore leading to short-circuiting and breakthrough issues. The present invention relates to wellbores connected hydraulically by multiple fracture zones; methods are directed to control for even flow distribution among fractures, regardless of heterogeneities in fracture hydraulic properties, and to control propagation of saturation fronts and thermal fronts in subsurface reservoirs.

An insulated joint in a pipe-in-pipe system comprises a weld that connects two inner pipes while respective outer pipes circumferentially enclose the inner pipes and terminate at a position distal from the weld. Respective rings are coupled to the inner pipes at the distal position and the outer pipes are welded to the rings. A joint insulation material covers the weld, and a sleeve segment covers the weld and joint insulation material. Preferably, the sleeve segment is formed from two half-pipe sleeve portions and welded to the rings to so secure the sleeve segment to the joined pipe-in-pipe segments. Contemplated pipe-in-pipe systems have significantly reduced thermal loss and provide strength sufficient for a pipe laying process that includes pipe bending and pipe straightening.

A method for predicting a deep geothermal field based on a temperature, pressure, and resistivity coupling constraint includes: equally dividing logging resistivity—overburden pressure—temperature data of m boreholes in a study area into N formations on a depth basis, and normalizing resistivity in each formation; deducing an accurate relationship characterization between a normalized resistivity, a temperature and a pressure in different formations of different formations; inverting an electromagnetic data volume in the study area to obtain a resistivity distribution characteristic, equally dividing an inverted resistivity into M formations, and normalizing the inverted resistivity into a normalized inverted resistivity; inverting a density distribution based on gravity observation data, and converting the density distribution into an overburden pressure; and calculating a distribution characteristic of a deep underground temperature field based on the accurate relationship characterization in different formations, the normalized inverted resistivity, and the overburden pressure.

Systems and techniques may be used for incorporating direct air carbon dioxide capture capabilities into a working fluid condensing process of a geothermal power plant. An example technique may include causing, using fans, air to flow across condenser coils of a condensing unit, through which power cycle working fluid is circulated, and through a direct air capture (DAC) filtration component, which separates carbon from the air, capturing heat from a geothermal working fluid, and using the heat as thermal energy input to the DAC filtration component or using electrical energy generated from the geothermal power plant as electrical energy input to power the condensing unit and the DAC filtration component. The example technique may include gathering the carbon separated from the air to be injected into a geothermal reservoir or repurposed for another industrial process.
