This article examines the factors affecting the productivity of horizontal oil wells in the example of the oil reservoir of the Karachaganak field. The paper presents several methods for calculating the productivity of horizontal wells, taking into account the geometry of the drainage zone. The formulas describing the productivity for each of the methods are analyzed, and the results of calculating the flow rates of horizontal wells for various parameters are presented. The authors considered the following methods: Yu. P. Borisov, S. D. Joshi F. M. Method Giger, method G. I. Renard, J. M. Dupug and Z. S. Alieva, V. V. Sheremet. All methods are based on the assumption of a stationary filtration regime, uniformity of the reservoir, and the location of the horizontal wellbore symmetrically or asymmetrically in thickness. Calculations were performed for well No. 918 in the Karachaganak field using various values of reservoir thickness, horizontal wellbore length, permeability, drawdown, and distance to the feed loop.
