Annotation:

One of the frequently used methods for increasing a well productivity factor is hydraulic fracturing (HF) of a formation, which involves creating new cracks in the productive formation under the influence of high fluid pressure. The method increases the recovery of products from the subsoil, but raises concerns among environmentalists due to possible negative consequences, such as groundwater pollution and seismic activity. In addition, with inaccurate calculations and actions, a crack in the productive formation formed by HF can break the productive formation, thus leading to water-flooding of the product. Also, one should bear in mind the high cost and complexity of this operation. The authors of the article consider Fishbone technology as an alternative to HF. Its technological indicators and economic efficiency are calculated. The results of the technology implementation are analyzed out using the example of a conventional field. The geological characteristics of the deposit are considered to predict the results of further development.
