"The main objective of the stage - preparation of the field to be put into the production."
At this stage, in turn, is the gradual transfer of functions and responsibilities of the project from the project team to the subsoil user. Also performed detailed design (stage "D"), is preparing detailed documentation of the approved baseline scenario, ordered equipment with long term manufacturing, in other words - implemented a detailed phased plan input field into the production, formation of the organizational structure of the subsoil user company.
The result of this stage is fully equipped with staff production subsidiary, the relevant development plan asset, completed pilot work (ODA), begins drilling of the priority areas of the field, constructed and put into operation the first phase of infrastructure facilities.
By and large, the stage "Define" - this is a rehearsal before the premiere. All roles are defined and rehearsed. Perhaps there were even held closed shows for a limited audience. The main costs (capital expenditure) have been spent. It remains to complete the installation of decorations, sewing costumes .... and we can begin. But the intrigue remains.
And our experience shows - to be sure of the correctness of the choice made will be when the field (development project which we did) will be fully developed. ... But without detracting from the importance of phase "exploitation", it is necessary to bear in mind - would not that effective project that went without changes to the implementation up to the end of production, and the one which provides for logical and premeditated sequence, choosing such equipment which will allow to make adjustments along the way, but without significant delay in the timing and without significant changes of target parameters of the project (production levels, costs, the key indicators of economic efficiency).
In conclusion, the narrative of the cycles (stages) of the project is necessary to emphasize the fact that the effectiveness of the implemented project we will know not soon. Sometimes it takes a few years (3-5) before appear the main drawback of the design (over or lack of capacity of _ objects of gathering system, treatment and transportation of produced products, underestimation complicating technological factors - the content of mechanical impurities, the rheological properties of the produced fluids, dynamics of water production / water cut and associate...more info
Sometimes this stage is preceded by stage "Preappraise", it is called initiation. "The main objective of both stages is to find at least one investment-attractive option of the project, it is also called the most probable (P50) or the base case". In addition to the base case are calculated optimistic (P10) and pessimistic (P90) scenarios that allow us to estimate the stability of the base case to the realization of key uncertainties in the development concept of such uncertainty are most often could be original oil in place, recoverable r...more info
"The main objective of stage - identification of alternative options for the development of the project, choice the basic variant and working on the optimization of the basic technical, technological and economic performance." At this stage, the main focus of the project team aims to elaborate the best scenario of 2-3 alternatives. Under the alternative is understood not so much completely different technology as elaboration of alternative options in case the internal heterogeneity of the project will be significant. In our own experience we can say that at thi...more info
The project at this stage started and gaining momentum. All authority transferred to the subsoil user. The project team has completed its work....more info
