Production Technology
Course Duration:
5 Working Days
Course Overview:
The course discusses a standard technique in production optimization to integrate the entire producing system from reservoir to surface facilities. The total production system consists of reservoir, near well bore, the well, tubular, artificial lift, gathering lines and manifolds. The objective of Nodal Analysis is to identify bottlenecks and optimize the entire system. On the contrary maximizing individual components, with suboptimal overall system may result in unnecessary costs with little or no increase in the production. In this context NODAL analysis becomes a powerful tool for production enhancement. NODAL analysis can be used in designing new wells that would deliver at optimum rates or diagnosing production problems in existing wells where well productivity is sub-optimal due to various reasons. The objective of this five days course is to have an in-depth understanding of NODAL analysis from back of the envelope calculations to excel based analysis to standard computer software.
Course Objective:
The course provides an insight in to the Field Development Process and the role of Production Engineering. It will explain the important concepts in reservoir and well productivity optimization, downhole completion concepts, completion equipment’s, wire line services, perforating, multiple zone completions, well intervention and workover, and advanced wells. The goal of the course is to provide an insight into the role of production engineer and basic concepts in well productivity, as well as covering various operational issues.
