Belinda Wong graduated from the University of Adelaide in 2011 with a Bachelor of Science (Honours) in Geology, Geophysics & Environmental Geoscience. Belinda was awarded first class honours for her thesis titled “Grenvillian-aged reworking of late Paleoproterozoic crust in the southern Aileron Province, central Australia: Implications for the assembly of Mesoproterozoic Australia”. After university, Belinda worked for Glencore Xstrata in copper mining and exploration in Mount Isa, Queensland before joining Beach Energy in 2015. She is currently a geologist in the Western Flank Oil E&A team, focusing on Namur/McKinlay field appraisal and stratigraphic Birkhead exploration in the Cooper Basin. Previously she has worked in the Cooper-Basin Joint Venture Group and Drilling Operations

PESA SA/NT April Technical Luncheon

Estimation of Hydrocarbon Liquid Yields in Gas Zones Using Mudlogs, Patchawarra Formation, Cooper Basin

When: Thursday 4th April, 12pm for 12:30

Where: Club Braggs at The Public Schools Club, 207 East Terrace, Adelaide SA 5000

Speaker: Belinda Wong (Beach Energy)

The Patchawarra Formation is a Permian age fluvial sand and coal measure system deposited in the Cooper Basin of Central Australia. Fluvial sand channels up to 20m thick form conventional gas reservoirs, and are inter-bedded with seal and hydrocarbon source play components of overbank silts, clays and coal seams. This stacked play system presents a challenge to completion optimization and efficiency, which are critical components for achieving an economic well. A key driver to the success and economics of a well is the presence of liquid hydrocarbons (LPG; Propane and Butane and condensate; Pentane plus). As the liquid yields composition varies significantly throughout the Cooper Basin, estimating the liquid yield in new gas zones is vital to valuations of any potentially commercial development in this area.

This presentation will introduce a new quantifiable method to forecast the liquid yields of specific gas zones utilizing mud gas logs. The method uses simple formulas applied to mud gas ratios to provide estimates of liquid yield per individual gas zone. Examples demonstrate the application of the method, calibration of fluid estimates to real PVT samples from corresponding gas zones and how the results have successfully optimized completion strategies in the Beach Energy operated Western Flank gas area. It is anticipated that with continued application, this simple method will become a useful tool in assessing the commerciality of gas wells and assist in identifying future exploration/appraisal and development targets.
