Abstract
Nowadays, the acquisition of Gas While Drilling (GWD) is applied widely in the Oil and Gas industry. The analysis of gas data plays a remarkable role in evaluating the hydrocarbon potential of the formations, especially in high-pressure, tight, and fractured carbonate reservoirs. In addition, the GWD finds its application in geo-steering to drive high-angle or horizontal wells to achieve maximized reservoir contact (MRC). This paper presents a procedure of interpreting gas data while drilling and its application in formation evaluation, determination of productive intervals, fluid characterization, and identification of fluid contacts. The study discusses the Upper and Middle Jurassic reservoirs in New Fields, West Kuwait. The excellent result of the GWD analysis efficiently identifies the hydrocarbon potentials and fluid contacts in New Fields. The well test results of recently drilled wells absolutely prove the successful deployment of the GWD method in West Kuwait.
