ABSTRACT

The paper presents results of hydraulic fracture modeling of parallel wells system using
special developed software. The crack propagation stability in a complex stress state
and the pressure effect were studied. Also, the maximum distance between hydraulically
fractured wells at which a connected crack formed was calculated. The data obtained
can be used to solve problems concerning coal seams degassing or coal bed methane
(CBM) production.
