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 associated gas ).
This fact, precisely lateness feedback and as a result, substantial capital investment risk of exceeding economical efficiency and obliges us be fixed at each step and verify all the results obtained.
Optimally, and we talked about in the beginning, to make such a stop at each stage of main cycle, firstly, with the assistance of independent experts in areas (geology, development, engineering, drilling, pipelines), and secondly (and this is very important) - with the involvement of the latter stages of the project representatives of the organization that will be responsible for the operation phase.
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 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 ...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
