Abstract

Field development of Giant gas reservoirs unlike oil reservoirs is typified with market linked necessities coupled with a compulsory plateau period. Techno-economics of gas reservoirs thus invariably take into cognizance the gas quality/ quantity/ input-pressure needs of the user industry along with delivery commitment period and profitability. Giants are thus developed with care and caution, as fall back for committed sales is rare and mid-course corrections are limited. Initial field development based on the delineation wells fall short in the desired level of characterization and absence of pressure - production history with time limits understanding from reservoir engineering perspective. Knowing the reservoir with time is thus the key and phase development the solution, but integrating the same in the business model is the challenge
