This book was released on 2018 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Taranaki Basin is located off the coast of the north island of New Zealand and is currently the only producing basin in New Zealand. Hydrocarbon accumulation in the Tui, Maari, and Maui fields is sourced to the Late Cretaceous and Paleogene units. Exploration of these units has extended from the continental shelf of the Taranaki Basin into the deep-water to the northwest. The Romney 3D survey and Romney-1 well are some the first public exploration projects to supply data from this area. The objective of this study is to estimate source rock quality and distribution of the Rakopi Formation in the Romney 3D survey utilizing seismic facies analysis, log motif, and geochemical evaluations. The Rakopi Formation records the northwest prograding megasequences of the Taranaki Delta. Seismic facies are defined by internal reflection configuration, reflection amplitude, frequency, continuity, and boundary relationships found in these sequences. Specific depositional environments are interpreted and calibrated using gamma ray log motif and biostratigraphy. These were used to generate paleogeographic reconstructions illustrating areas with the best source potential within the Rakopi Formation. Although seismic stratigraphy does not quantify source rock quality, higher quality organic-rich facies are identified based on geochemical analysis and tied to specific intervals on the Romney-1 well. The results of this study confirm primary source potential from type II/III, oil and gas prone non-marine coal-rich facies. This source interval contains type II kerogen with excellent total organic content, hydrogen index above 300, and above average generative potential. A potential secondary type I, oil prone, marine algal source facies may also be preserved in the far northwest portion of the Romney 3D and extend westward beyond the survey.

This book was released on 2017 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of Plio-Pleistocene mass transport deposits (MTD) have been identified in the deepwater Taranaki Basin, in New Zealand, using the Romney 3D seismic survey, which covers an area of approximately 2000 km2. One of these MTDs has been chosen for description and interpretation based on high confidence mapping of its boundary surfaces. The deposit exhibits an array of interesting features similar to those documented by researchers elsewhere plus a unique basal feature unlike those previously observed. The basal shear surface exhibits erosional features such as grooves, "monkey fingers", and glide tracks. Internally, the MTD is typically characterized by low impedance, chaotic, semi-transparent reflectors surrounding isolated coherent packages of seismic facies interpreted as intact blocks rafted within the mass transport complex. Distally, the deposit presents outrunner blocks and pressure ridges. The new element described in this work consists of a composite feature that includes a protruding obstacle ("shield block") on the paleo-seafloor that acted as a barrier to subsequent flows as they advanced downslope. These blocks disrupt the incoming flow and result in elongate, downflow negative features ("erosional shadow scours"), which are then infilled by the mass transport deposit, and are preserved as elongate isochore thicks. Kinematic evidence provided by various structures suggests that the MTD flow direction was SE-NW toward bathyal depths. The features presented and the absence of extensional headwall structures, such as local arcuate glide planes and rotated slide blocks, suggest that this part of the deposit belongs to the translational to distal domain of the MTD, and its source area is expected to be somewhere toward the SE in a paleo continental slope.

This book was released on 2016-10-06 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Practical Petroleum Geochemistry for Exploration and Production provides readers with a single reference that addresses the principle concepts and applications of petroleum geochemistry used in finding, evaluating, and producing petroleum deposits. Today, there are few reference books available on how petroleum geochemistry is applied in exploration and production written specifically for geologists, geophysicists, and petroleum engineers. This book fills that void and is based on training courses that the author has developed over his 37-year career in hydrocarbon exploration and production. Specific topical features include the origin of petroleum, deposition of source rock, hydrocarbon generation, and oil and gas migrations that lead to petroleum accumulations. Also included are descriptions on how these concepts are applied to source rock evaluation, oil-to-oil, and oil-to-source rock correlations, and ways of interpreting natural gas data in exploration work. Finally, a thorough description on the ways petroleum geochemistry can assist in development and production work, including reservoir continuity, production allocation, and EOR monitoring is presented. Authored by an expert in petroleum geochemistry, this book is the ideal reference for any geoscientist looking for exploration and production content based on extensive field-based research and expertise. - Emphasizes the practical application of geochemistry in solving exploration and production problems - Features more than 200 illustrations, tables, and diagrams to underscore key concepts - Authored by an expert geochemist that has nearly 40 years of experience in field-based research, applications, and instruction - Serves as a refresher reference for geochemistry specialists and non-specialists alike
Download or read book Seismic Data Interpretation and Evaluation for Hydrocarbon Exploration and Production written by Niranjan C. Nanda and published by Springer. This book was released on 2016-03-10 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces readers to the field of seismic data interpretation and evaluation, covering themes such as petroleum exploration and high resolution seismic data. It helps geoscientists and engineers who are practitioners in this area to both understand and to avoid the potential pitfalls of interpreting and evaluating such data, especially the over-reliance on sophisticated software packages and workstations alongside a lack of grasp on the elementary principles of geology and geophysics. Chapters elaborate on the necessary principles, from topics like seismic wave propagation and rock-fluid parameters to seismic modeling and inversions, explaining the need to understand geological implications. The difference between interpretation of data and its evaluation is highlighted and the author encourages imaginative, logical and practical application of knowledge. Readers will appreciate the exquisite illustrations included with the accessibly written text, which simplify the process of learning about interpretation of seismic data. This multidisciplinary, integrated and practical approach to data evaluation will prove to be a valuable tool for students and young professionals, especially those connected with oil companies.

This book was released on 2015 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this study was to construct a new stratigraphic framework for the Victorian section of the onshore Otway Basin, while answering unresolved questions about the basin's early rift history. These include the order in which individual depocentres were formed, the timing of deposition of laterally varying stratigraphic packages, which units were confined to individual rift depocentres and how the transition between depositional environments was controlled by rift related tectonism. The approach first involved the integration of stratigraphic correlations, petrophysical interpretation, drill-core descriptions and biostratigraphy with seismic facies analysis. This resulted in the identification of at least two new lithostratigraphic members and the construction of a new stratigraphic framework for the sediments. Structural analysis was then undertaken by building a 3D structural model which was used to calculate cumulative displacement rate across depocentre bounding faults and sediment accumulation rates within the main depocentres. This analysis suggests that changes in rates of fault activity were the primary control on temporal shifts in depositional environments. The results were then enhanced by building a series of continental sequence stratigraphy models for each depocentre. These demonstrated that a series of age correlatable regional tectonic events controlled common variations in the vertical stacking order of stratigraphy in all the depocentres. Sequence stratigraphy interpretation also allowed detailed palaeogeography mapping which in turn led to the construction of a high-resolution volumetric model of the Crayfish Group members. This resulted in a revised chronostratigraphic framework for the onshore Otway Basin, which provided a basis for explaining the relationship between fluvio-lacustrine sedimentation and tectonism during the early history of intercontinental rift systems. Finally, the resulting geological model was used to evaluate its consequences on the thermal history and source rock maturation of the basin. This was done by building a series of 1D and 3D thermal models. These models allowed investigation of the potential for both conventional and unconventional petroleum systems and carbon capture and storage potential. They demonstrate that the highest quality source rocks in the system are mature for hydrocarbon generation but are restricted to a series of ancient lacustrine environments within the central Otway Basin. They also demonstrate that highest quality reservoirs are buried deeply enough and are hot enough to store carbon dioxide in its supercritical phase within many of the existing drilled structural culminations.
