The effect of the asymmetric arrangement of the horizontal shaft at different parameters of the formation anisotropy

The article is devoted to the calculation of the productivity of a horizontal oil well for the development of oil or oil and gas fields is important. There is no doubt that for powerful formations, dense reservoirs, fractured deposits with vertical cracks, etc., the use of horizontal wells is becoming a necessity and has practically no alternative. But this provision is not a guarantee of obtaining an oil flow rate for a long time that significantly exceeds the flow rate of vertical wells. The stability of a horizontal well with a high flow rate requires the study of the influence of several factors on the performance of horizontal oil wells. In particular, these factors include: reservoir parameters (permeability, anisotropy, depression on the formation, etc.); the location of the horizontal trunk relative to the roof and sole of the skid-shaped formation and pressure loss in the horizontal trunk.
