On the 28th of June 2017, the Polish Ministry of the Environment announced the boundaries of the tender areas selected for the third licensing round for concessions for prospection, exploration and exploitation of hydrocarbons. This round is going to be proceeded in the 4th Quarter of 2018 and 1st Quarter of 2019. The geologists of the Polish Geological Survey selected 15 tender areas (promising for discoveries of conventional and unconventional oil and gas fields) based on the geological data resources stored in the National Geological Archive, other published data, as well as the knowledge and experience of employees of the Polish Geological Institute - National Research Institute and the Polish Ministry of the Environment. All selected areas are located onshore. In this article we describe 10 tender areas located in the Gdańsk, Pomerania and Wielkopolska petroleum provinces. Other tender areas situated in the Carpathians (Błażowa, Proszowice W, Rudnik-Lipiny, Wetlina) and in the Lublin Petroleum Province (Ryki) will be discussed in the next publication. Three areas: Wejherowo, Bytów and Braniewo-Miłakowo are located in the northern Poland (Gdańsk Petroleum Province). The exploration targets of these areas are generally related to structural-lithological traps in the Middle Cambrian beds of the Baltic Basin, as well as to unconventional shale oil and gas in the Lower Paleozoic. Seven tender areas are situated in the northwestern Poland (Pomerania and Wielkopolska Petroleum Provinces). Three of them - Chodzież, Piła and Leszno are dedicated to conventional gas deposits in the Rotliegend sandstones and, in some cases, also oil deposits in the Zechstein/Main Dolomite. Excluding the Leszno tender area, chances for tight gas discoveries exist within the Rotliegend sandstones. The exploration target of the Konin tender area is related to possible conventional fields in the Jurassic and Lower Cretaceous beds. In the Pomerania region the exploration target is generally related to conventional hydrocarbon deposits in the Devonian, Carboniferous and Permian (Rotliegend and Zechstein/Main Dolomite). Three tender areas are situated within the region of: Sierpowo, Orle and Chełmno. As a rule, a concession is granted for a period of 10 to 30 years and is divided into 2 phases: 1) prospecting and exploration phase (which lasts from 4 to 5 years and can be extended to another 2-year period), 2) production phase. Every entity interested in obtaining a concession needs to undergo the qualification procedure. We believe that this publication will contribute to better understanding of the offered tender areas and encourage activity in the Polish oil and gas sector.

Ostatnie kilkanaście lat to okres dynamicznego rozwoju metod i technologii stymulacyjnych. Rozpoczął się on od momentu zakupu nowoczesnego sprzętu zabiegowego oraz nowoczesnego wyposażenia laboratorium zajmującego się problemami stymulacji wydobycia. Te zmiany pozwoliły na wprowadzanie do powszechnego zastosowania nowatorskich technologii intensyfikacyjnych. Dotyczyły one głównie dwóch obszarów. Pierwszy z nich to zmiana technologii w zabiegach hydraulicznego szczelinowania. W okresie kilkunastu lat wdrożono do stosowania nowoczesne ciecze technologiczne do szczelinowania oraz nowe materiały podsadzkowe w celu zwiększenia efektywności zabiegów. Drugi obszar doskonalenia technologii intensyfikacyjnych to zabiegi szczelinowania kwasem i kwasowania matrycowego. W tej dziedzinie przygotowano i wdrożono do stosowania technologie wieloetapowego kwasowania złóż, wykorzystania żeli i emulsji kwasowych do szczelinowania kwasem i kwasowania matrycowego. Wszystkie wspomniane technologie są stosowane obecnie w pracach intensyfikacyjnych wykonywanych złożach ropy naftowej i gazu ziemnego w kraju i zagranicą.

Last decade it is period of dynamic development of stimulation methods and technologies. The first stage of this was purchase of new stimulation service and stimulation laboratory equipment. It allows to introduce new technologies for industry use. The new technologies was prepared for two types of stimulation acivities. The first on is hydraulic fracturing. New kind of stimulation fluids and new proppants were prepared to increase treatment efficiency. The second area of activities is development of novel acid fracturing and matrix acidizing methods. New technologies of gelled and emulsified acid were prepared for industry use. All prepared technologies are used for stimulation treatment of oil and gas wells in Poland and abroad.
