Period of 2000-2015 in exploration and production of hydrocarbons was not the most successful. The last major discovery of new reservoirs took place in the second half of XXth century and first half of XXIst century, when the reservoirs of Kościan, Brońsko, BMB and LMG were discovered. Unfortunatelly, following years did not develop these significant discoveries. We can wonder if it was connected with the lack of exploration strategy, problems with financing or less availibility of discovering new reservoirs. Performing work over last three years enabled though first exploration successes, to be mentioned Podkarpacie and Wielkopolska. The total resources estimate of 64 million equivalent barrels of petroleum (boe). New reservoirs are Kramarzówka,
In times of global crisis, there is a dynamic change in the European gas market. This leads to:
- decline or stagnation in demand for gas in the industrial sector;
- growing importance of unconventional natural gas;
- LNGmarket development especially in terminal condensing due to the availability of rawmaterials derived from unconventional gas deposits (USA, Canada);
- development of regasification terminals in Europe due to the possibility of receiving additionalmaterial;
- development of gas exchanges;
- development of cross-border gas pipeline connections leading to a progressive increase in the integration and linkages between markets;
- emergence of unconventional gas in particular shale gas and coal bed methane; in Poland the potential benefits from shale gas exploitation offering opportunities for its wider use in the energy sector;
- attention drawn to the role of unconventional gas, particularly shale gas;
- periodic surplus raw materials for the European market;
- renegotiation of long-term contracts for European customers;
- changes in contracts, which include the introduction of partial indexation to the exchange of gas markets, modification of TorP clauses, contract volume shift to later years;
- stronger bargaining position for the buyer of raw materials;
- possible long-term changes in the valuation of raw material in Europe;
- growing importance of short and medium-term contracts;
- changes in distributor relations - [client on national markets (meaning unclear)];
- activity of new entrants to the gas markets.
This paper presents the existing situation in the energy market in Poland in terms of the types of fuels used especially natural gas in the generation of electricity. It references Poland’s current energy relations with European countries, particularly with respect to the European Union. The analysis includes the size of unit energy consumption in selected EU countries. In addition, it reviews plans to build a major gas plant in Poland.
The potential in coal seams gas resources in Poland is estimated to be similar to known conventional reserves (about 150 bln s.cu.m) but present efficiency of utilization is much lower. Many coalmines utilize this gas for a small-scale heating and electricity generation, but global utilization efficiency is as low as 60%. In Poland, methane is recovered mainly for safety reasons from coalmines. This paper presents new possibilities for methane production from abandoned coalmines and from unmineable, deep coal seams. In the first case the gob gas ventholes can be drilled from the surface, in the second case multilateral wells technology can be employed. In the paper, the simulation models of mined and unmined coal seams are presented and discussed. The results are evaluated from both technical and economical point of view. Economical analysis showed positive NPV and IRR=10%. Two case studies presented in this paper show that both abandoned coalmines and unmineable coal seams could be effectively utilized for coalbed methane production using advanced drilling technologies. During the last decade many coalmines over the Europe have been abandoned for both economical and environmental reasons, others are in the terminal state of production. However, some of these mines still contain large resources of methane that could be used for the local purposes like heating or electricity generation. The case study of the Moszczenica coalmine in Poland, including computer simulation of the coal and methane production shows that gob gas can be successfully recovered using new wells drilled from the surface. Presently, the deep unmineable coal seams are often not utilized from economic reasons. The case study presented in this paper shows that they can be effectively utilized for coalbed methane production using advanced drilling technologies like multilateral wells.
