Article is devoted to project management experience for the development and implementation of the corporate hydraulic fracturing simulator aimed at improving the efficiency of hydraulic fracturing technology and providing technological independence in the field of engineering software for the design of hydraulic fracturing. It is shown that the following solutions were used to develop a physically adequate model of the fracturing process: the application of the Planar3D-concept to describe the fracture geometry; fully-coupled fully-implicit solution for the elasticity and hydrodynamics; proppant transport solution for each of the pumped proppants, taking into account the rheological properties of the fracturing fluid, the gravitational settling / floating of the proppant, the proppant slowing / acceleration due to interaction with the fracture walls and between the proppant particles.
To keep the high pace of the project implementation, the following organizational solutions proved effective at the software development stage: quick release of the working beta version, the presence of the active pilot test group, bug and tasks tracking system, daily assembly of the new software version, regular distribution of the new software version to the pilot group testing, the constant ranking of planned and unplanned tasks, the start of user training at the beta stage, the constant benchmarking and increasing the productivity of the calculation core. It is noted that the choice of a solid calculation core without separation into program elements for individual physical processes allows to methodically and organizationally concentrate efforts to optimize the core and increase its productivity, which is critical for numerical grid simulation of the fracturing based on Planar3D-concept.
