This article presents applying of system engineering approaches to develop software “Drilling Cost Engineering” to assess the well cost. V-model of lifecycle was used to develop this product and the following steps were taken: business requirements specification, system requirements specification system design, architecture design, detailed design, coding, unit testing, system testing, integration testing, validation and verification, operations and maintenance. The specific practices and tool were applied at each stages of lifecycle, such as identification and poll of stakeholders, methodology development, prototyping, concept model, functional requirements, database model, external environmental of the system, technical scope and architectural design, testing procedures. Cooperation of drilling engineers, IT architectures, programmers, business analysts, database specialists on each stage of system lifecycle allowed producing unique software to make assessment of well cost on different stages of oil and gas projects at different levels of available information. Using of system engineering approach at project realization helped to pass efficiency of the main gates of project and realize the software for integration well cost estimation. Initial and claimed business effects have been achieved on the stage of verification and validation, what is the result of success of using system-engineering approaches. Next stage is improvement of developed system “Drilling Cost Engineering” and V-model is transforming to W-model. The main tasks for improving are integration of this system to conceptual engineering process in Gapzrom Neft Company, increasing the detail of input data and the depth of existing system capabilities; development of new functionality of a matrix system for assessing the cost of well construction for ranges of variable conditions, expansion of the organizational volume of the project.
