Petroleum and natural gas deposits

Description

The topic shows the outlines of the oil and gas deposits according to the current geological knowledge. Petroleum or natural gas deposits are economically viable, natural accumulations of petroleum or natural gas and, if necessary, other hydrocarbons in storage rocks. The outlines of the oil and gas deposits presented in the data set represent boundaries that can be of a diverse nature: In a simple case, this is the interface between the oil/gas accumulation and the surrounding marginal water (so-called oil/gas/water contact). In other geological situations, the boundaries can also be formed in whole or in part by the spatially changing rock properties or tectonic structures, such as faults or discordances. Furthermore, for various reasons, the geological structure of a deposit is not always sufficiently known to define its boundaries in an unequivocal and precise manner. In these cases, the limits concerned have been estimated to the best of our knowledge for the present data set, e.g. by using known gas or oil down-to(s) or estimates of the areas of the deposits drained by extraction. The boundaries of the deposits are also subject to temporal variability, which starts with the commencement of production and the associated extraction of oil or natural gas. With a few exceptions, the present dataset reproduces the initial outlines of the deposits, i.e. the outlines found at the beginning of production. In addition to geological boundaries, there may also be boundaries in the dataset that have an administrative background, e.g. to separate storage areas of different operating companies. The data set is based on geological structure maps of the deposits, which are regularly transmitted to the LBEG by the respective operating companies as part of their reporting on their mining activities. The scale of these structural maps depends on the size of the respective deposit and is usually between 1:10,000 and 1:50,000. This data set is therefore not suitable for applications on a larger scale. Since no structural maps are available to the LBEG for a few small deposits that have already been abandoned, in these cases the outline of the deposit was estimated via a strike circle placed around the corresponding production well(s). Cumulative production data refer to the reference date 31.12. of the previous year and are reported in the 3rd or 4th quarter of each year. Updated calendar month of a year. If the cumulative production data are added to totals for federal states, the sums differ slightly from the sums published in the LBEG’s annual report ‘Oil and natural gas in the Federal Republic of Germany’, as the annual report also takes into account test production volumes that originate from individual wells and did not lead to field development. Furthermore, the annual report divides the production volume of the cross-border Sinstorf oil deposit according to a certain ratio between the Länder of Lower Saxony and Hamburg.
