we know that a kill well with drilling relief well is a one of prevalent process and all of company know a managing this work is a one of hard working . In this article , we try to study managing kind of relief wells and show relief well planning. relief well planning was started as a contingency immediately after the blowoutoccurred with full resources derected to that effort after the second drill pipe kill attempt failed. these design process steps , in generic terms are the following : defining relief well objective , defining kill point s , defining hydraulic communication method, evaluate position uncertainty , evaluate gelogy, define attack angle , develop an electromagnetic ranging strategy , determine surface location s , develop relief well trajectory , define relief well casing program , define survey program evaluate kill hydraulics determine the number of relief wells define kill equipment , and project refinement for drilling and kill. the team was broken into four primary units each with leader.<\div>

we have two kinds of blowout that are underground gas blowout and shallow gas blowout. Underground blowouts involve significant downhole flow of formation fluids from a zone of higher pressure the flowing zone to one of lower prssure the chaarged zone or loss zone. they are the most commonof all well control problems. this phenomenon differs from cross flow wich typecally occurs within a long perforated interval and involves little or no reserves loss or escalation hazard. underground blowouts can occur in drilling wells or producing wells, and are thought to be the most common in the latter because of tubulars corrosion in older completions. two factors make shallow gas drilling a difficult challenge . first unexpected pressure at the top of the gas bearing zone, due most often to the gas effect dictated by zone thickness and \ or natural dip, can be significant . this pressure is usually unknown seismic surveys being often unable to give an idea either about thickness or in–situ gas concentration. in more complex situations , deep gas may migrate upwards along faults. gas blowout is one of the dangerous event that may be happen in all of the gas or oil wells. this kind of blow out is one of unknown and uncontrolled event that can be accurate in all fields .<\div>

the collapse of casing and tubing may lead to the loss of a well . Studies on this issue have been of great interest to the oil industry . At present , we have the technology and systems that can identify the most relevant contributing factors to this phenomenon , which permits development of preventive measures that will save significant economic resources. collapse is a complex phenomenon with a great many factors and parameters that influence its effect. the collapse phenomenon is commonly attributed to suspected quality problems in the pipe. however , studies show there are a set of causative factors, such as : wear on casing wear due to buckling increased external pressure due to temperature improper depressurization geostatic loads overburden due to plastic formations and tectonic activity . we can predict some of these factors and do preventive methods to reduce costs of collapse but some are not predictable and have huge costs to surmount them like what happened in dangan field because of unreliability of well stiuation.<\div>
