Analiza badań niektórych właściwości ropy naftowej ze złoża LMG
(2007) Janocha, Andrzej; Steliga, Teresa; Bęben, Dariusz
Oil field Lubiatów-Międzychód-Grotów (LMG) is diversified geologically. Samples of each part of the oil field deposits possess peculiar properties. Smooth exploitation can be carried on only when the composition and properties of the natural gas and the crude oil well are known. Special attention should be paid to threats connected with precipitating hydrates, paraffins, asphaltenes and salt. The results of analyses of oil field LMG are presented in the paper. The analysis of these results points out to the trends to be taken into consideration when designing technological solutions.

Demulgatory i ich wpływ na procesy eksploatacji ropy naftowej
(2007) Bęben, Dariusz; Jewulski, Jan; Janocha, Andrzej
A considerable part of exploited oil is emulsion, which according to the World's statistics constitutes 25-35% of extracted oil. The presence of emulsion decreases oil production from wells, resulting in the increase of cost of its separation and acceleration of corrosion of production utilities. A number of methods of oil emulsion separation exist; however majority of them are based on the surfactants (demulsifiers). A specific surfactant may be efficient only for a given emulsion. It cannot be used for other emulsion without prior studies and analyses as may result in stabilization or formation of hardly separable multiple emulsions. The demulsifier should be so selected as not to cause corrosion of utilities. It should also be non-toxic and easily removable from sewage water. These issues are discussed in the paper.

Specyfika eksploatacji ropy ciężkiej ze złoża "Lubaczów"
(2006) Jewulski, Jan
The proposal of choice of the heavy oil production method from ,,Lubaczów' reservoir is presented in article. This selection was made with regards of oil physicochemical properties and their change with temperature and geological properties of reservoir. Author proposes to heavy oil production the use of rod modified pumps or screw pumps.

Wtórne metody eksploatacji złóż karpackich na przykładzie złoża ropy naftowej Osobnica

Natural oil leaks in the Carpathians have aroused interest of people inhabiting the Carpathian Foothills since time immemorial. Successive studies of the geological setting and productivity of Carpathian anticlinal folds resulted in the discovery of numerous oil fields. When applying only the so-called primary exploitation methods, involving natural field energy, primary geological reserves may be exploited at low recovery factors of ca. 10-35%. Therefore, in order to increase oil recovery, secondary exploitation methods are used. The Carpathians are an excellent example of applying the above-mentioned methods with very good results for many years, since the 1930s. One positive example of a field in which primary methods were accompanied by secondary ones, i.e. water and gas injections, is the Osobnica oil field. Up to the present day, recovery factors obtained at the site with the introduced methods attained a level of 33% of geological reserves.

Zastosowanie odwiertów multilateralnych na złożach ropy naftowej w późnej fazie eksploatacji
(2007) Stopa, Jerzy; Rychlicki, Stanisław; Wojnarowski, Paweł
Multilateral systems as compared with the conventional wells offer a number of advantages, e.g. possibility of increasing resources through opening a part of the unproduced reservoir, acceleration of production, lowering the cost of realization of exploitation project owing to the use of a common vertical section for a number of horizontal or inclined branches. Thanks to the high oil price, now this type of wells is an attractive alternative of opening deposits at any stage of exploitation. The technical efficiency of a multilateral well was assessed on the example of a partly depleted oil field in Poland. Using computer simulation methods, a comparative analysis of vertical, horizontal and multilateral wells was carried. Moreover, the efficiency of these wells was evaluated. According to the simulation results, the use of a multilateral well significantly increased the production and uniform depletion. This was due to the fact that a large part of the field was being exploited.

Zastosowanie odwiertów rozgałęzionych w eksploatacji złóż ropy i gazu
(2007) Stopa, Jerzy; Rychlicki, Stanisław; Wojnarowski, Paweł; Kosowski, Piotr
Multilateral wells in comparison with traditional, vertical wells may bring many benefits like: increase of the reserves, significant increase of production, decrease of operational and capital costs and higher profits. But on the other hand one multilateral well requires substantially higher capital costs than single vertical well and such wells are more risky and more technically complicated. In this paper authors present evaluation of technical and economic efficiency of multilateral wells applied to exemplary oil and natural gas fields in Poland. Variant, numerical simulations were conducted in order to evaluate productivity of multilateral and vertical wells and their results were used in economic estimation. KEYWORDS: multilateral well, numerical simulations, oil exploitation, gas exploitation.
