The Antarctic continent, which is nearly completely covered by a thick ice sheet, and the surrounding ocean with its fringing belt of sea-ice, ice shelves and drifting icebergs, offer challenges to geological investigations that seek to unravel the history of one of Earth's last frontiers.

A proposal that the megacycles of the Campanian strata in the Cordilleran foreland basin in southern and central Utah resulted from interaction of a seasonal, wet monsoonal climate and topography rather than lowstand deposits formed by downstream changes in sea level.

Marita Bradshaw, an AAPG member and retired geologist with Geoscience Australia, has spent her career helping to uncover Australia’s oil and gas potential and is now pleased to see recent large discoveries on the continent and the expansion of the export LNG industry. A symposium will be held in her honor this month at the AAPG-SEG International Convention and Exhibition (ICE) in Melbourne.

Unconventional plays in the Permian Basin are nothing new to the shale scene, as the basin has been horizontally drilled and hydraulically fractured for years. Still, a new approach for evaluating sweet spots, particularly in the Avalon Shale of the play’s Delaware Basin, is slowly changing the way unconventional resources are explored – and perhaps one day, developed.

When 3-D seismic technology became a must-have tool for the E&P crowd beginning in the mid-1990s, there was considerable scurrying to get up to speed on this then-daunting high-tech application. Even today, it’s not uncommon to see a non-geophysicist’s eyes glaze over when a discussion turns to even basic seismic terminology like P-waves, which move through both solid rock and fluids, and S-waves, which travel only through rock.

The goal of this workshop is to review mature fields and to identify the amount and nature of oil that can be recovered, and to evaluate competing strategies for economically producing the remaining reserves. In addition to looking closely at fields, we will review new and improved technologies that may help revitalize reservoirs and overcome problems such as low pressure, paraffin, corrosion, and more. We will identify companies willing to offer a “no money down” approach, or other forms of innovative financing. In addition to reviewing the technology, we will review case studies.

Join AAPG Europe and the Lithuanian Geological Survey for this exciting Core Workshop. This workshop will follow on from the 'Hydrocarbon Exploration in Lithuania and the Baltic Regions' event taking place at Vilnius University on 24th – 25th October.

The Early Palaeozoic Hydrocarbon System in the Baltic Basin and adjacent territories involves Middle-Late Cambrian, the Late Ordovician (Mossen & Fjacka Formations) and the Early Silurian Graptolitic Shales source rocks and the major complexes of reservoirs, associated with Middle Cambrian sandstones, Ordovician and Silurian reefogenic and carbonate build-ups.

The major reservoirs of the Baltic Basin are:

  • The Middle Cambrian (Deimena Fm). Sandstones - Producing
  • The Early Ordovician (Tremadoc, Salantai Fm.) sandstones
  • Late Ordovician (Early Ashgill) organogenic limestones/carbonate buildups
  • Late Silurian (Late Ludlow/Pridoli) reefogenic carbonate build-ups
Core Presentation:
Cores presented from the following 3 reference wells:

1. The Middle Cambrian - the Early Ordovician quartz sandstone reservoirs

The Middle Cambrian Deimena Group sandstones comprises all the major economically important oil fields located Lithuania, Latvia, Kaliningrad district and Polish onshore and Baltic Sea offshore. The other, much less significant, potential reservoirs are the Late Ordovician carbonate build-ups of Gotland (Sweden) and Southern part of Lithuania and the Late Silurian carbonate reefogenic buildups in South Lithuania (Zdanaviciute O., Sakalauskas J. eds., 2001, Zdanaviciute, Lazauskiene 2007; Kanev et al., 1994).

The reference sections would demonstrate core from fine-grained (dominated by 0.25-0.1 mm fraction (30-75%)) quartz sandstones containing thin clay and siltstone interlayers. The sandstones are to a different degree litified by compaction and predominantly cemented by quartz and diagenetic quartz cement that has the major control on reservoir properties.

The Early Ordovician

The early Ordovician Tremadoc age (Pakerort Regional Stage, Salantai Fm.) strata distributed rather locally are a reservoir unit at the base of the Ordovician succession, comprising quartz sandstones and quartz siltstones of only 0.5 to 4 m thick. It overlays directly to the Middle Cambrian Deimena Group sandstones and together form one reservoir unit with similar reservoir properties. The formation is overlain by the Early Ordovician shales. Several small oil fields are producing from this reservoir unit in the western part of Lithuania.


2. The Late Ordovician (Early Ashgill) and Late Silurian (Late Ludlow/Pridoli) organogenic limestone and reefogenic carbonate buildups reservoirs

The Late Ordovician - The Late Silurian

The reservoir rocks within the Silurian succession are the Wenlock - Early Ludlow and Pridolian reefogenic carbonates comprising secondary dolomites and reefal limestones with thicknesses of tens of meters. Silurian sequences are locally distributed along the Eastern slope of the Baltic Basin. The Wenlockian - Early Ludlow strata are up to 28 m thick; the effective porosity ranges from 12% to 17% and average permeabilities – 12-15 mD. The most favourable conditions for the formation of non-structural traps (reef-associated, lithologic-stratigraphic and combined) are associated with the carbonates (mainly stromoporoidal and crinoidal limestones) sucession of about 90 m thick of the late Ludlow- earliest Pridoli (Minija and Ventspils Formations). The reservoir rocks has mean porosities of 6-15 % and up to 26% and permeability ~465mD, reaching up to 2400mD. The Late Silurian reservoir rocks mainly occur in central and southern Lithuania in the central part of the basin.


3. Late Ordovician (Mossen & Fjacka Formations) and the Early Silurian Llandovery Black Shales

The Late Ordovician Shales

In the central and eastern part of the Baltic Basin the potential source rocks comprises dark grey and black shales of the Late Ordovician Late Caradoc-Early Asghill Fjacka and Mossen formations. Both units are generally thin, reaching only up to 5–10 m; the thicknesses of Fjack & Mossesn Formations are 6 m and 4 m respectively. TOC content are mostly in the 0.9 to 10 % range, with occasional higher values of up to 15 %. The source rock facies are kerogen type II and II-III.

The Early Silurian Shales

Potential source rocks in the Silurian succession are found within the Llandovery, Wenlock and, presumably, Ludlow-aged strata. The Silurian source rocks are composed of dark grey and black graptolite shales and dark grey and black clayey marlstones. Within the Baltic Basin organic matter content generally ranges from 0.7 to 9–11%, but can be as high as 16.46 % (fig. 5.5.b; Zdanaviciute, Lazauskiene, 2004). In terms of petrography, the organic matter is dominated by syngenetic, sapropelic and marine material, together with vitrinite-like particles and abundant faunal remains. Detrital sapropel is scattered as very fine-grained particles and lenses. Liptinite (up to 20%) generally occurs together with dispersed liptodetrinite in sapropelic organic matter, or more rarely as scattered particles. (Zdanavičiūtė, Swadowska 2002, Zdanaviciute, Lazauskiene, 2004, 2007, 2009).

Maturities in the area of interest attain at pre-Silurian level 1.3% Ro and around 1.0% Ro at Silurian source rock level, and reach 1.9% on the prominent West-Lithuanian local temperature high Zdanaviciute, Lazauskiene, 2004, 2007, 2009)

The paradigm of sequence stratigraphy has entered a new phase and these once revolutionary concepts are now applied in pre-drill exploration at ever-increasing resolution. The concepts also prove useful in production geology, especially in enhanced oil recovery efforts in previously abandoned fields.
