Annotation:
Well test surveys are important source of data for geological structure identification and O&G fields development control. The most valuable surveys results acquired over non-stationary filtration regimes. The most interesting surveys conducted at pressure draw-down during production, but requires initial reservoir pressure. Article propose two mathematic models for well test interpretation of data gained in wells with alternating flow-rates producing from homogeneous reservoir with linear no-flow boundary and two parallel no-flow boundaries. These models make available identification of capacitive-conductivity properties and reservoir pressure. Testing models on synthetic data envisage good results.
