Figure 1: The strike-slip tectonic in analysed hydrocarbon zone

Table 1: The list of e-log intervals analysed in this paper. The mark means absolute depth.

Citation of figures and tables – it is cited like “…it can be seen on Figure 2…” or “…measurements taken into calculation (Table 4) clearly show…” etc.

Spelling – paper must be written in English. For spelling check please use British English (UK) spell checker.
