Abstract

Summary

The B14 field, discovered in 2013, is a multi-TCF Upper Miocene carbonate pinnacle reef discovery lying in Central Luconia Sarawak, Malaysia. During the exploration drilling of the field, neither cuttings nor wireline logs were acquired. Data from a single production test indicated a significant gas column of up to 550m as well as the presence of up to 3,500ppm H2S.

The uncertainty on the maximum H2S concentration in the field especially towards the GWC and base of the structure is concerning due to its toxicity and impact on material selection during the appraisal and development phase of the field as well as its impacts the field’s full life-cycle economics.

In the absence of abundant well and field data, a semi-regional study was carried out to investigate the likely factors controlling the distribution and concentration of H2S in nearby offset fields within the eastern Central Luconia province. It was observed that the underlain water of these gas fields acts as potential H2S scrubbers and therefore impacts the H2S concentration of these fields. This conclusion is used to deduce the maximum concentration of the B14 field as well as future exploration and development wells and fields respectively.
