Investigation of solid precipitates and petroleum phase in Kauri-A4, -E1 and -E2 wells, Onshore Taranaki

This report discusses six separator liquid samples from Kauri-A4, -E1 and -E2 and three solid samples from Kauri-A4 and -E2 supplied to GNS by Swift Energy New Zealand Ltd for geochemical analyses. The objectives of the study were to: 1. Compare the geochemistry of the liquids produced from the Kauri-E2 well before and after fracturing of the reservoir. 2. Compare the geochemistry of the liquids produced from the Kauri-A4, -E1 and -E2 wells and evaluate any fluid heterogeneity. 3. Compare the geochemistry of the liquids produced from Kauri-A4, -E1 and -E2 to the solid precipitates from Kauri-A4 and -E2 and assess if any genetic relationships exist between the liquids and solid deposits. 4. Infer the source(s) and maturity(ies) and identify the degree of any biodegradation for the liquids produced from Kauri-A4, -E1 and -E2.
