Effective Solutions in Planning Field Development

It is impossible to imagine a modern oil/gas producing field without a reservoir simulation model of the production target. It ensures optimal operations and use of investments, maximum risk reduction at all stages of the field development. As the oilmen emphasize, a development simulation model can significantly improve the effectiveness of decisions regarding drilling of new wells or operations in the old ones. 

A hydro-dynamic field model is one of the most essential tools used for planning geological and engineering operations at the field. This model makes it possible to develop a maximum accurate forecast on the field development, verify efficiency of particular actions and create an optimal plan for further field development. However, current programs for hydrodynamic simulation are too complex to be used at the field: Reservoir modellers working at research institutes and simulation centers and on-site specialists communicate literally in “different languages”.

This is one of the main reasons why at most fields hydro-dynamic simulation is not used at all; the developed models are put on the shelf, and most often obsolete methods are used at the fields – two-dimensional maps of reserves distribution and expertise of the experienced specialists regarding the features of the wells in operation. 

Specialists of Rock Flow Dynamics set an ambitious goal for themselves: to develop a powerful program of a new generation, which would be able to perform full-range calculations of flow properties, being maximally easy-to-use at the same time. They succeeded and developed a software package tNavigator.

“We managed to bring the algorithm of work with the engineering program to the level of a common PC user. Instead of traditional methods for the model operation, which require months of special training of engineers, we arranged simple and foolproof buttons. Our specialists spent plenty of time on developing a simple and accessible interface which can be used without any special training. Now tNavigator can be used both at the modeling departments, and at the departments of petroleum engineering and well intervention planning at the fields,” described Vasily Shelkov, General Director of Rock Flow Dynamics.

Actually, the tNavigator software enables on-site specialists “to play” with the field using the ready model: the software has a special button for any action which could be later realized at the field. A graphical software interface makes it possible at any moment to introduce necessary alterations into the current field model and immediately assess the results of this or that action. “With the help of a mouse, it is possible to plan a well according to the selected trajectory, change the well operational mode or perform hydraulic fracturing and immediately see the effect of it on the production curve,” says Vasily Shelkov. It is possible to clearly model in the simulator the effect of hydraulic fracturing, bottomhole formation zone treatment and a number of other operations, optimize the flooding system in various areas of the field and calculate the production forecast, without being a professional modeller, which is not possible with similar software of
