A recent study addressed the modelling challenges of Alpha* gas condensate field. Alpha gas condensate field has a gas in-place of about 1 TCF, and both condensate and black oil production in addition. The field has been producing from two reservoirs SI and DI, for the past 26 years. Alpha field is subdivided into two segments called the Central Area and the Northern Area which are separated by a fault as shown in Figure 2. * Not its real name. One of the most unusual features of Alpha field are the'phase switch wells'.
In conventional drilling scenario, the Drilling Manager has to deal with similar drilling problems several times during field development phase. In addition to this he has to manage several service providers which results in increased workload. This increased workload prevents him to focus on the solutions of drilling problem & drilling optimization.
Integrated Drilling Services is a new concept in which all services and equipments are integrated under one contract. It is a contractual model which is technically and economically feasible with efficient risk management. This model reduces non productive time and non conformances with efficient project management and Technology Advancements in order to encourage Drilling Managers "Doing Right Things?? rather than "Doing Things Right??.
This paper describes an engineering approach towards well optimization and efficient project management. Moreover, economic benefits are also the part of the study.
