The present invention comprises a method of Enhanced Petroleum Recovery (EPR) combining technical, economic, environmental and social effectiveness to increase the recovery factor of onshore or offshore fields having a high degree of exploitation, more precisely through the use of a substance miscible with the diverse types of petroleum of low fluidity found in various regions. More specifically, the present invention refers to the use of solvents such as light liquid fractions of petroleum, for example diesel oil and gas oil, a light petroleum, and the essential oils derived from renewable sources such as for example biodiesel, used pure or mutually admixed in any proportion, for injection into a geological formation through an injection well, there resulting a final mixture (petroleum / injected solvent) presenting much lower viscosity and much greater fluidity than the original petroleum, having an impact throughout the petroleum production chain. The present patent presents real gains in all phases of the production chain.For the purposes of the present invention biodiesel is understood to be oil having characteristics similar to diesel produced from mineral sources, however having been produced from renewable sources, usually agricultural sources.

An improved organo-refining process to produce low ash clean coal from high ash coal, comprising: mixing coal, solvent and a co-solvent to produce a slurry; feeding the slurry to a reactor by pumping; extracting a coal-solvent mixture from the reactor; feeding the extracted mixture to a flasher unit; recovering about 30% of the solvent from the flashing unit; feeding the remaining heavy material to an evaporator; extracting about 60% of solvent from the evaporator; discharging the residue from the evaporator to a precipitator having water which produces a coal slurry; filtering the slurry in a rotary drum; collecting the super clean coal as a residue and feeding the filtrate into a distillation unit; and separating the water and the organic material in the filtrate to recover at least 7 to 8% of the remaining solvent.

The invention discloses a microcosmic location selection system of a high-altitude mountain wind power plant. The microcosmic location selection system is formed in a way that a data input module, a preprocessing module, a scheme database, a microcosmic location selection module, a power generation amount calculation module, a technical economy module and a data output module are connected in sequence, wherein the microcosmic location selection module is also independently connected with an electronic module and a civil engineering module; and the technical economy module is also independently connected with the electronic module and the civil engineering module. The microcosmic location selection system integrates professional templates of specialties including a technology specialty, an electronic specialty, a civil engineering specialty, a techno-economic specialty and the like in a wind power plant engineering design specialty, can lower a manual intervention rate while convenience is brought for coordinated management, minimizes human factor influence, improves the consistency and the accuracy of the microcosmic location selection design achievement of the high-altitude mountain wind power plant, realizes the intellectualization, the systematization and the high efficiency of microcosmic location selection work, and solves the difficulty that microcosmic location selection can not be accurately and reasonably carried out in the design of the high-altitude mountain wind power plant.

The invention discloses a horizontal well drilling borehole trajectory optimization method and belongs to the technical field of oil and gas development. The optimization method comprises the steps of: determining n technical and economic indicators related to optimization of a wellbore trajectory in a horizontal well, the technical and economic indicators comprising at least one engineering technical indicator and at least one economic indicator; establishing m horizontal well drilling well trajectories; obtaining the values of each technical economic indicator corresponding to each horizontal well drilling well trajectory; normalizing the value of each technical economic indicator corresponding to the drilling trajectory of each horizontal well; determining the weight value of each technical economic indicator; calculating the combined utility values of the wellbore trajectories for each horizontal well separately, wherein the combined utility value is the sum of the value of each technical economic indicator in the wellbore trajectory of each horizontal well, and the sum of the normalized value and the corresponding weight value; determining the optimal horizontal well drillingwell trajectory based on the combined utility value of each horizontal well drilling well trajectory.
