Elk Hills Monterey Formation - Challenge of Incorporating Complex Natural Fractures to Improve Production Understanding Elk Hills, initially designated as Naval Petroleum Reserve No. 1, is a large anticlinal field discovered in 1911 in the southern San Joaquin Valley of California. Elk Hills is a complex structure with multiple reservoir horizons including a highly fractured bio-siliceous unit. Focus of this paper will be on the Antelope Shale (Antelope) member of the Monterey Formation which has variability in production due to variations in net pay and degree…

MAJOR EXPLORATION SUCCESS IN THE SURINAME-GUIANA BASIN The Suriname-Guiana Basin at the north coast of South America has proven to be extremely prolific with some 11 billion BOE rec discovered since 2015. Exxon is still drilling successful exploration wells in Guyana and the past year Apache had three discoveries in Suriname. Everything indicates that there is still a lot to be found. In my talk I will give details about the geological setting and structural framework of the basin, the…

A Framework for Inclusion of Faults in Coal Seam Gas Risk Assessments, Narrabri Project Case Study Assessments for Coal Seam Gas (CSG) projects may be required to consider the potential hydrological impacts of faults on surface and near-surface groundwater assets. This paper presents three distinct end member geological scenarios and outlines methods for characterising fault-related groundwater flow within a risk assessment context. Scenario 1 A regional aquitard isolates the water assets from the coal seams. There is little risk of…

Hydrocarbons in a new early Paleocene sedimentary section recovered from the Campbell Plateau, south of New Zealand, by IODP Expedition 378 International Ocean Discovery Program (IODP) expedition 378 “South Pacific Paleogene Climate” took place offshore New Zealand from January to February 2020. Expedition 378 recovered the first continuously cored, multiple-hole Paleogene sedimentary section from the southern Campbell Plateau at Site U1553. Coring at Site U1553 reached a maximum depth of 584.3 mbsf and recovered a 581.16 m long sedimentary succession…

Event cancelled Microbial enhancement of Coal Seam Gas reservoirs - A multi-disciplinary approach to enhance biogenic gas production In the subsurface, coal seams represent something of an oasis for microbial life. The environment is anoxic, warm, often wet and contains an abundant, but intractable source of carbon held in the organic matter of the coal. In eastern Australian coal seams, microbial community complexity depends on temperature with hotter, deeper coals typically hosting less diverse communities. Regardless, coal seam biodiversity ranges…
