Seismic Reflection Methods in Offshore Groundwater Research

Marine geophysical methods, in particular seismic reflection data, can help characterize offshore hydrogeological systems and yet the existing global database of industrial basin wide surveys remains untapped in this context. In this paper we highlight the importance of these data in groundwater exploration, by reviewing existing studies that apply physical stratigraphy and morpho-structural interpretation techniques to provide important information on—reservoir (aquifer) properties and architecture, permeability barriers, paleo-continental environments, sea-level changes and shift of coastal facies through time and conduits for water flow. We then evaluate the scientific and applied relevance of such methodology within a holistic workflow for offshore groundwater research. Keywords: submarine groundwater; continental margins; offshore water resources; seismic reflection 1. -
18 December 2020 Reliance and Bp Announce First Gas from Asia's
18 December 2020 Reliance and bp announce first gas from Asia’s deepest project • Commissioned India's first ultra-deepwater gas project • First in trio of projects that is expected to meet ~15% of India’s gas demand and account for ~25% of domestic production Reliance Industries Limited (RIL) and bp today announced the start of production from the R Cluster, ultra-deep-water gas field in block KG D6 off the east coast of India. RIL and bp are developing three deepwater gas projects in block KG D6 – R Cluster, Satellites Cluster and MJ – which together are expected to meet ~15% of India’s gas demand by 2023. These projects will utilise the existing hub infrastructure in KG D6 block. RIL is the operator of KG D6 with a 66.67% participating interest and bp holds a 33.33% participating interest. R Cluster is the first of the three projects to come onstream. The field is located about 60 kilometers from the existing KG D6 Control & Riser Platform (CRP) off the Kakinada coast and comprises a subsea production system tied back to CRP via a subsea pipeline. Located at a water depth of greater than 2000 meters, it is the deepest offshore gas field in Asia. The field is expected to reach plateau gas production of about 12.9 million standard cubic meters per day (mmscmd) in 2021. Mukesh Ambani, chairman and managing director of Reliance Industries Limited added: “We are proud of our partnership with bp that combines our expertise in commissioning gas projects expeditiously, under some of the most challenging geographical and weather conditions. -
Geophysics Were Associated with Salt-Domes, and Were Detected Through Gravity Surveys with Torsion Balances and Pendulums (Geophysics 224, Section B)
C2.9 Hydrocarbon exploration with seismic reflection Seismic processing includes the steps discussed in class: (1) Filtering of raw data (2) Selecting traces for CMP gathers (3) Static corrections (4) Velocity analysis (5) NMO/DMO corrections (6) CMP stacking. (7) Deconvolution and filtering of stacked zero offset traces (8) Migration (depth or time) Question : This sequence is for post-stack depth migration. How will it change for pre- stack depth migration? Processed seismic data can contribute to hydrocarbon exploration in several ways: ●Seismic data can give direct evidence of the presence of hydrocarbons (e.g. bright spots, oil-water contact, amplitude-versus-offset anomalies). ●Potential hydrocarbon traps can be imaged (e.g. reefs, unconformities, structural traps, stratiagraphic traps etc) ●Regional structure can be understood in terms of depositional history and the timing of regression and transgression (seismic stratigraphy, seismic facies analysis). This can sometimes give an understanding of where potential source rocks are located and the relative age of reservoir rocks. 1 C2.9.1 Direct indicators of hydrocarbons 2.9.1.1 Bright spots As shown in C1.3, a gas reservoir can have a P-wave velocity that is significantly lower that the surrounding rocks. This can lead to a high amplitude (negative polarity) reflection from the top of the reservoir. ● However, not all bright spots are hydrocarbons. They can be caused by sills of igneous rocks or other lithological contrasts. In areas of active tectonics, ponded partial melt can produce a bright spot (e.g. Southern Tibet). ● It should also be noted that true amplitudes are not always preserved in seismic data recording and processing. -

Physical Logs i. Caliper Logging A caliper log is a well logging tool that provides a continuous measurement of the size and shape of a borehole along its depth[1] and is commonly used in hydrocarbon exploration when drilling wells. The measurements that are recorded can be an important indicator of cave ins or shale swelling in the borehole, which can affect the results of other well logs. ii. Temperature Logging iii. Pressure Logging b. Electric Logs i. SP logging - spontaneous potential The spontaneous potential log, commonly called the self potential log or SP log, is a passive measurement taken by oil industry well loggers to characterise rock formation properties. The log works by measuring small electric potentials (measured in millivolts) between depths in the borehole and a grounded electrode at the surface. -

Geothermal Aspects of Hydrocarbon Exploration in the Nojrth Sea Area
Geothermal Aspects of Hydrocarbon Exploration in the Nojrth Sea Area CARL-DETLEF CORNELIUS Cornelius, C.-D. 1975: Geothermal aspects of hydrocarbon exploration in the North Sea Area. Norges geol. Unders. 316, 29-67. A statistical analysis of the distribution of hydrocarbon phases indicates that in a time-temperature diagram these phases are restricted to hyperbola confined areas. Thus, the 'liquid-window-concept' has been improved by inferring a time correction. Based on a survey of recent temperature conditions and the recon struction of paleo-temperatures, it has been applied to the North Sea region. Furthermore, the survey of present geothermal gradients has made it evident that the region north of the Variscan orogen is a type region of an inverted geothermal realm. This can be explained by the abundance of source beds and other sediments of low grade lithification in the subsiding areas. The maximum temperatures have been preferentially determined by the vitrinite (coal) reflec tivity method; because it allows measurements without physical-chemical alterations of the organic matter and because the reflectibility depends on the gradational changes of aromatization, which is one of the significant processes during the formation of crude oil. A Table for the determination of time corrected temperatures from vitrinite reflectivities has been added to this paper. The relationships between recent and paleo-temperatures have been sys tematized and some paleo-thermal events have been interpreted: a. The temperature high above the Bramsche Massif which formed during the Austrian orogeny. b. The Mid-Jurassic event which led to the formation of the gas deposits in the Rotliegend of the British part of the southern North Sea. -
