Abstract: FIELD: oil and gas industry. 
     SUBSTANCE: invention relates to technologies of the oil and gas industry, in particular, to methods for determining the filtration characteristics of the reservoir of inter-well intervals. A method for determining the filtration-capacity properties of the inter-well interval of the reservoir consists in conducting studies of the reacting well using the pressure recovery curve (hereinafter – PRC) or pressure stabilization curve (hereinafter – PSC), recording the change in the flow rate of the reacting well and obtaining a model curve of the change in the bottom-hole pressure of the reacting well using historical data of the flow rate measurement at the reacting well and conducted studies using the PRC or PSC method. During the operation of the reacting well, without stopping it, hydraulic monitoring of the reservoir between the interacting disturbing and reacting wells is carried out to obtain the actual curve of the change in bottom-hole pressure at the reacting well. Differentiation of the response at the operating reacting well, during hydraulic monitoring, is carried out by subtracting the pressure values at the points of the model curve from the corresponding points of the actual curve to obtain the pressure response curve cleared of extraneous noise. The pressure response curve is interpreted to obtain quantitative characteristics of the inter-well interval of the reservoir, taking into account the cycles of the disturbing well.  
     EFFECT: invention is aimed at providing the possibility of obtaining the most accurate quantitative characteristics of the filtration parameters of the inter-well intervals in the drainage area of the disturbing and reacting wells without stopping the reacting well stock.

     SUBSTANCE: invention relates to the oil and gas industry, namely to methods for remote ignition of a natural gas stream (an open gas fountain) in an accident at gas fields. The method for remote laser ignition of open gushing of a gas well consists in the fact that the ignition of open gushing of a gas well is carried out by the thermal effect of laser radiation on sand particles located in the gas fountain. The intensity of the laser radiation is set in the range (1.5÷2) ×10 4  W/cm 2 . In the process of igniting the open gushing of a gas well, the laser beam is automatically moved at a speed of 1 m/s along the axis of the preventer in the direction of the gas outflow from the cut-off area of the gas preventer with a change in the angle of the place α within 0÷45°. After each segment of the movement of 1 m, there is a pause in the movement of 18÷20 s.  
     EFFECT: reduction of the time of emergency ignition of natural gas while increasing the safety of emergency work.
