Identification of the Shale Production Model

The technique of appraisal have been proposed for the evaluation of the recoverable reserves according to production schedules for the total wells number of the same calendar year into operation. NPV formula representation and necessary conditions for optimality have been proposed. Recoverable reserves and rate of production (production decline) have been identified for the wells put into operation in 2012 – 2017. As a trend, the initial production rate of wells and recoverable reserves grew from year to year, as well as investments in one well. The ties between the length of horizontal wellbores multiplied by the volume of injected proppant and production parameters have been studied. The choice of production technology depends on the actual oil price. With an increase in the oil price, optimaly coordinated increase both the recoverable reserves and the rate of production at the well.
