Annotation:

Maximum recovery of hydrocarbon reserves remains one of the main tasks of the oil and gas industry. Special attention should be paid to such large fields, the main objects of which are low-permeable deep-lying layers of the Jurassic deposits. The main advantage of horizontal wells is associated with an increase of the contact area of the well with the formation, thus allowing significant increase of hydrocarbon recovery factor. One of the current issues at present is the efficiency of their drilling and advantages over directional wells as well as the length of the horizontal wellbore, etc. Directional wells are not just a tool for oil and gas production, but also a multifunctional tool – their flexibility and efficiency make them an indispensable element in modern methods of hydrocarbon development. The authors of the article present a comparative analysis of the efficiency of oil reserves extraction by directional and horizontal wells at the YuV1 oil and gas condensate field.
