The study [5] describes the process and results of radial jet drilling at some fields for improved oil production. At the Tarim oil field in China, the oil production rate was increased significantly by 200%. [PERSON] and [PERSON] (2013) carried out a survey RJD at the Donelson West oil field (the reservoir consists of limestone). Research showed that the monthly recovery oil rate increased from 197 barrels before radial drilling to 1100 barrels per month after RJD [5]. [PERSON] et al. 2011 described experiments of the application of radial jet drilling technology on three oil wells in Egypt (Belaym oil field), where there was a decrease in oil production and at one of the three experimental oil wells, no oil production rate increase was achieved. The reason was the poorly cemented sandstone and the canal colmation. This demonstrates one of the disadvantages of radial drilling since it is not recommended for use in unconsolidated sandstone [6; 7]. [PERSON] et al. [8] describe the experimental use of RJD at Oil India Limited (OIL) to recover oil from a low-permeability reservoir with a high recovery rate near the well bore, by means of reinforced stimulation, in order to stimulate the oil selection. Research shows that the conditions for the successful use of the technology are: shorter time of stimulation with pumped liquids; presence of a thick oil-saturated reservoir; radial canals that stretch beyond the mined zone, involving the non-covered interlayers into production; good reservoir energy. [PERSON] [9] assesses the application of RJD in different reservoir conditions. It may be noted that the greatest production increments are typical for low-permeability reservoirs with four radial canals. Comparing the production rate increment depending on the quantity and length of canals and the reservoir permeability, it can be concluded that the greatest effect is achieved at low permeability of the reservoir, four canals, and with a canal length of 300 feet (91 m). The study [10] describes the use of radial drilling in Egypt. The technology was used in two oil wells for stimulating oil production in a carbonate reservoir. In the first well, the oil production rate increased from 220 to 289 barrels per day, and in the second well, it grew from 465 to 686 barrels per day. The papers [9; 10; 11; 12] note that RJD is most efficient for high-viscosity oil that frequently forms stagnant zones in the low-permeability parts of the reservoirs. The study [13] analyzes the efficiency of using the radial jet drilling technology at the D1 site of the Vakhitovskoe oil field (Russia). The success of the radial jet drilling was assessed as 75%. The technology increased the oil production rate by 1.5 to 5 times. [PERSON] et al. [14] show the average annual efficiency indexes of well stimulation during the recent years in the Perm Territory. According to which the efficiency changed from 38 to 48% for acid treatment, from 38 to 49% for hydraulic formation fracturing, ND from 42 to 78% for RJD. The effect of the drilling was assessed as the achievement of the planned production rate [1]. According to the research data [15], RJD can be regarded as the main alternative to extra small-radius sidetracks. In the articles [16; 17; 18], statistical methods were applied to compare RJD, acid treatment, and re-perforation in the Perm Territory. Radial jet drilling was more effective for the oil production rate increment. From the literature, it was noted that the radial drilling technology is a global practice, but the actual data that the previous studies are based upon appear insufficient, therefore, the influence of the geological and physical properties of the reservoir on the efficiency of the technology has not been properly studied. The accumulated experience of using the technology at the Perm Territory oil fields (Russia) allows for the use of statistical methods and machine learning methods for the analysis.
