Challenge & Concept of Early Production Set-Up for Commercialization of Hydrocarbon Resources: Step Towards Energy Transition

Abstract An exploratory onshore location of ONGC was released for exploring hydrocarbon potential. The well was observed to produce nearly 1.0 LSCMD gas with associated condensate and approximately 77 m3/d water from Object-I in gas-bearing zone and 5700 SCMD gas, 21 m3/d oil and 4 m3/d water from Object-II in oil-bearing zone. A scheme was conceptualized for early monetization of the discovered hydrocarbon resources by developing an Early Production Set-up (EPS). Simulation studies were carried out using process simulator based on available input data. Vertical lift performance (VLP) analysis and flow hydraulic study were carried out for both the objects for estimating FTHP & FTHT of both the objects. Various modes of artificial lift methods were analyzed for the object to achieve the target. The study also revealed possibility of hydrate formation while reducing the well-fluid pressure to match the EPS battery limit. After studying a series of possible options, a combination of hydrate mitigation techniques was conceptualized for hydrate mitigation consisting of multiple bean arrangement and heat-tracing of well-fluid line. The challenge of commercialization of these resources can be taken up by generating green energy and producing green power as an alternative source.
