Abstract: Reservoir perforation allows for interfacing of the pay-zone and the production casing in the petroleum wellbore. Perforations are key interface for fluid movement in completion and they are extremely important for effective design and itis to beensured that well has appropriate number and size of perforation. For directing formation petroleu mfluid from subsurface zone, cased well must be perforated. Perforationis created by implementing controlled detonation of steel casing, cement casing and surrounding rock using specially design edand manufactured shaped charges. Perforating shockwaves and high impact pressureshattertherockto breakdown and propagate crack through it. Numerical model of acuboidal rock sample is createdto decide the preferred fracture plane. Under balance forces have also been taken in account to calculate Von-misesstress. Simulations are performed in order tostudy the behavior of compound stress during chargede to nation of rock and casing fracture. Crack propagation in different directions and principal planes has been found out. Usingthese results, location ofchargesoncasingcanbe defined to propagate fracture indesired locations. This report presents numerical analysis of fracture propagation during charged detonation using finite element methods (FEM).. 2014 CAFET-INNOVA TECHNICAL SOCIETY.
