A century ago, a gusher helped transform Venezuela from an agricultural country known as an exporter of coffee, cacao and cattle into one of the world’s largest oil producers. It was front-page news on the world’s most important newspapers. The country’s most significant 20th-century discoveries took place in the Maracaibo Basin between 1910 and 1925 and were based on surface geological exploration of concessions held by American and European companies. One of the strikes, the large La Rosa Field, was discovered in 1917 by Venezuelan Oil Concessions, a Royal Dutch Shell affiliate, on a 3,000-square-mile concession.

In the world of oil and gas, an increasing number of plays in stratigraphic traps are being made – in large part due to ever-evolving seismic technology. The Discovery Thinking forum at the annual IMAGE conference in August served to highlight some of these plays in offshore frontier basins and the role that geophysics played in their discovery. “We are seeing more giant stratigraphic fields, and seismic is the key,” said past AAPG President Charles A. Sternbach, chair of the Discovery Thinking forum. “And, we are seeing more oil found at greater depths. Unconventional plays are migrating outside of the Western Hemisphere.”

Deepwater turbidite reservoirs hold some of the largest petroleum reservoirs and thus are important exploration targets. By identifying and mapping the diverse architectural elements of the turbidite system and placing them within the correct geologic framework, a skilled interpreter can predict which components of the system are more likely sand or shale prone. Seismic data and seismic attributes also provide insight into the connectivity or compartmentalization of different parts of the reservoir which can be used to estimate the number of wells needed to drain the reservoir.

This debate began decades ago: How much of the planet's natural gas is abiotic – made up of methane with nonbiological origins? At times, the scientific back-and-forth argument has resembled a slow-motion tennis match, with a new volley coming every few years. Now, Daniel Xia thinks he has helped deliver a winning smash across the net. His findings were most clearly laid out in a recent article “Validity of geochemical signatures of abiotic hydrocarbon gases on Earth,” by Xia and coauthor Yongli Gao, published in the Journal of the Geological Society.

In 1949 an historic oil field was discovered under the Caspian Sea. The field was named “Neft Dashlari, which in Azerbaijani means “Oil Rocks,” and it was a milestone in the development of the global oil industry. Oil Rocks, an iconic “city in the sea,” pointed the way to modern offshore drilling as we know it today.

There are two main oil and gas producing sedimentary areas in France: the Paris Basin and the Aquitaine Basin. The presence of oil seeps and bitumen deposits has been known since ancient times in the western part of the Aquitaine basin, a 35,000-square-kilometer triangular polygon bordered to the north by the city of Bordeaux, to the east by Toulouse and to the south by the Pyrenees Mountain chain separating France from Spain. These hydrocarbon shows were observed close to surface anticlinal structures such as the Sainte-Suzanne dome, southwest of Pau or in the caprocks of salt diapirs at Salies de Bearn and Dax to the north.

Presented by Kevin C. Hill, Associate Professor, University of Melbourne Gravity modelling of Australia's southern margin reveals that the initial rift with Antarctica was beneath the current Ceduna Delta. A regional, high-quality seismic traverse from the coast to oceanic crust across the Bight Basin has been assembled and interpreted in detail, then balanced, restored, decompacted, and replaced at paleo-water depths. The Late Cretaceous Ceduna Delta developed above a Late Jurassic-Early Cretaceous rift basin in three stages punctuated by significant pulses of uplift and erosion across areas >100 km wide and with up to 1 km of erosion. The Cenomanian White Pointer delta prograded into deepening water and hence underwent gravitational collapse. This was terminated in the Santonian when the Antarctic margin was pulled out from below, thus supplying heat to a remnant thicker outer margin crust, causing doming and erosion. Importantly, this established the saucer-shaped geometry of the Ceduna Delta that persisted throughout its development, so that any hydrocarbons generated in the southern half of the basin would have migrated towards this outer margin high. The Tiger Formation was deposited in shallow water in a full rift basin prior to breakup, which was followed by regional thermal subsidence. The Hammerhead delta developed on the newly formed passive margin but was terminated by another pulse of uplift and erosion, perhaps associated with a change in plate motion at the end of the Cretaceous. The finite element modelling of this proposed tectonic evolution will test its validity and predict hydrocarbon generation and migration through time.

VG Abstract

Production from unconventional petroleum reservoirs includes petroleum from shale, coal, tight-sand and oil-sand. These reservoirs contain enormous quantities of oil and natural gas but pose a technology challenge to both geoscientists and engineers to produce economically on a commercial scale. These reservoirs store large volumes and are widely distributed at different stratigraphic levels and basin types, offering long-term potential for energy supply. Most of these reservoirs are low permeability and porosity that need enhancement with hydraulic fracture stimulation to maximize fluid drainage. Production from these reservoirs is increasing with continued advancement in geological characterization techniques and technology for well drilling, logging, and completion with drainage enhancement. Currently, Australia, Argentina, Canada, Egypt, USA, and Venezuela are producing natural gas from low permeability reservoirs: tight-sand, shale, and coal (CBM). Canada, Russia, USA, and Venezuela are producing heavy oil from oilsand. USA is leading the development of techniques for exploring, and technology for exploiting unconventional gas resources, which can help to develop potential gas-bearing shales of Thailand. The main focus is on source-reservoir-seal shale petroleum plays. In these tight rocks petroleum resides in the micro-pores as well as adsorbed on and in the organics. Shale has very low matrix permeability (nano-darcies) and has highly layered formations with differences in vertical and horizontal properties, vertically non-homogeneous and horizontally anisotropic with complicate natural fractures. Understanding the rocks is critical in selecting fluid drainage enhancement mechanisms; rock properties such as where shale is clay or silica rich, clay types and maturation , kerogen type and maturation, permeability, porosity, and saturation. Most of these plays require horizontal development with large numbers of wells that require an understanding of formation structure, setting and reservoir character and its lateral extension. The quality of shale-gas resources depend on thickness of net pay (>100 m), adequate porosity (>2%), high reservoir pressure (ideally overpressure), high thermal maturity (>1.5% Ro), high organic richness (>2% TOC), low in clay (<50%), high in brittle minerals (quartz, carbonates, feldspars), and favourable in-situ stress. During the past decade, unconventional shale and tight-sand gas plays have become an important supply of natural gas in the US, and now in shale oil as well. As a consequence, interest to assess and explore these plays is rapidly spreading worldwide. The high production potential of shale petroleum resources has contributed to a comparably favourable outlook for increased future petroleum supplies globally. Application of 2D and 3D seismic for defining reservoirs and micro seismic for monitoring fracturing, measuring rock properties downhole (borehole imaging) and in laboratory (mineralogy, porosity, permeability), horizontal drilling (downhole GPS), and hydraulic fracture stimulation (cross-linked gel, slick-water, nitrogen or nitrogen foam) is key in improving production from these huge resources with low productivity factors.
