Modeling of oil displacement by the injection of hot water through high permeable well radial channels
(2011) Bekibaev, T.T.; Kabdulov, Serik Zejnullič; Sahariev, Bolat Bejsembaevič; Žapbasbaev, Uzak K.; Kenzhaliev, B. K.; Assilbekov, B. K.
In this paper we investigate the efficiency of water-oil displacement by injecting hot water into the stratum through the highly permeable radial channels, created by jetting method of drilling. Increasing of the oil recovery factor and the volume of cumulative production by 7-12% showed as a result of our calculations.
Badania skuteczności działania inhibitorów korozji dla wytypowanych odmian stali w środowisku cieczy kwasującej
(2011) Fabia, Bogusława; Bielewicz, Danuta; Stachowicz, Agnieszka
The most commonly used method in intensification of hydrocarbon production is acid treatment. It is connected with corrosion of production pipes. The aim of the research was to determine effectiveness of four corrosion inhibitors: ACI 130A, AI 600, Antykor PP, SAFE-COR which are used in the industry and Inhibitor PPT which was created on the Faculty of Drilling, Oil and Gas, at the AGH University of Science and Technology. The research was conducted on temperature of 20 degrees of Celsius (293.15 K) and 60 degrees of Celsius (333.15 K) on five samples of different types of steel strength (according to nomenclature API: J-55, K-55, L-80, N-80 and P-110). The most effective inhibitors and the most resistant types of steel were selected as materials in production of production pipes.
Polyglycol mud for drilling in clay and shales
(2011) Gąszcz, Krzysztof; Suchar, Mariusz; Wysocki, Sławomir
Drilling a wellbore in formations containing water-sensitive shales can cause many serious technical problems. Especially mud which enable safe drilling in shales and clays formations must be characterized not only by features of standard modern mud, but also has to reduce water adsorption and thus hydration of clays and shales. This paper was prepared so as to present the results of laboratory investigation in which a glycol and ion - polymer fluid based on potassium salt was made. Obtained mud is characterized by high-temperature resistance, good rheological properties, low water loss and resistance to salt ions.
Model stanowiska laboratoryjnego przeznaczonego do pomiarów przepuszczalności stwardniałego zaczynu uszczelniającego, zbudowany w oparciu o dynamiczną prasę filtracyjną HTHP
(2011) Hendel, Jacek; Złotkowski, Albert; Stryczek, Stanisław
The qualification of permeability cement rock is very difficult process, which success depends from good tightening and correct measuring value of liquid by sample filtration. Lower permeability, typical for cement rock, requires use high pressure. Investigation then will be exact, if the volume of liquid filtration will be considerable. Therefore to get high volume liquid to measurement was adapted filtration press HPHT (High Pressure, High Temperature), which give possibility to make this research in pressure 8 MPa.
Production logging test in horizontal wells
(2011) Kabdulov, Serik Zejnullič; Jiyembayeva, Kalamkas; Kalev, B; Manhanova, Azhar Erlanovna
Horizontal drilling technology has significantly influenced the industry's approach to the development and recovery of hydrocarbons. Advances in drilling technology have led to improved well productivity, increased drainage areas, especially in low permeability reservoirs. These day companies adopted an approach that has assigned a high priority to monitoring horizontal wells in order to maximize benefits. The testing and logging programs are aimed to assess the flow profile of the horizontal wells, optimize well production rates and plan future production and workover strategies. For this reason development of new methods and technologies has become crucial. This paper covers peculiarities of production logging test techniques used in horizontal wells. This includes technological as well as technical innovations based on deeper understanding of the phenomena through detailed research of this area.
