A survey of private and public collections produced information on 410 fluted point yielding localities within a single county in east central Ohio. Analysis of techno-functional attributes of the fluted points resulted in the definition of four general settlement types including large and small workshop/occupations, chert processing loci, and food procurement/processing loci. The distribution of these loci in relation to various features of the local paleoenvironment suggests that Paleo-Indian bands were seasonally exploiting the diverse environments of the Appalachian Plateau. Subsistence activities appear to have focused primarily on dispersed, non-aggregated game species such as white-tailed deer. The dense concentration of fluted points here may simply reflect the high redundancy in the Paleo-Indian land use system in areas with limited loci of availability for critical chert resources.

The article presents the results of the analysis of legislation and practice of its application in the sphere of legal regulation of relations on the design of oil field development, including fields with hard‑to‑recover minerals. It is noted that the definition of «hard‑to‑recover minerals «is not fixed in the regulatory documents. To develop the concept of «hard‑to‑recover mineral deposits», it is necessary to attract special knowledge from the field of Geology, Economics of the geological industry. Signs of oil deposits (as well as other minerals) located in specific geological conditions, for example, in shale formations; at great depths in the earth’s interior, and therefore requiring special technological and technical solutions for their extraction, it is advisable to fix at the level of law. In this regard, special design rules are required for deposits containing hard‑to‑recover minerals. In order to implement the main provisions of the Energy strategy, the state should ensure systematic and comprehensive legal regulation of economic (business) relations in the field of oil production by adopting a special law.

Market Capitalisation

Oil production from Cooper/Eromanga started in 1978, peaked in the 1980s and began a steady decline. Oil production from the Western Flank commenced in 2002 and has steadily increased. In the year until July 2014, a total of 8.6 million BBL of oil was produced from 16 active fields along the Western Flank, bringing the cumulative total to 24 million BBL. Western Flank oil has underpinned a ten-fold growth in market capitalisation in four listed Australian companies: Beach Energy, Drillsearch Ltd, Senex Energy and Cooper Energy. Two sandstone plays dominate the Western Flank petroleum geology: the Namur Sandstone low-relief structural play and the mid-Birkhead stratigraphic play. The use of 3D seismic has improved the definition of both plays, increased exploration success and optimised field appraisal and development drilling. Success rates have improved despite most Namur structural closures being close to the resolution margin for depth conversions (less than 8 m). Seismic attribute mapping is being refined in the more difficult search for mid-Birkhead stratigraphic traps with recent exploration discoveries indicating improved success. Reservoir properties in the Namur are excellent with multi-Darcy permeability, unlimited aquifer strength, low gas/oil ratio (GOR) and low residual oil saturation. This combination leads to an oil recovery factor greater than 75%. Initial free-flow production rates commonly exceed 6,000 BBL per a day. The mid-Birkhead reservoir is also of high quality but the lack of a strong aquifer drive reduces primary recovery. New and re-processed 3D seismic and water-flood projects are expected to drive further discoveries, reserve and production growth.
