“…The petroleum extracted from Kazakhstan fields is mainly characterized by a high content of paraffin hydrocarbons, which is one of the factors for asphalt-resin-paraffin deposits (ARPD) formation 1,2 . Intensive formation of ARPD on the inner surface of oilfield and refinery equipment, especially in cold period of year, significantly reduces pumping units efficiency, impairs the throughput of oil pipelines and shortens the turnaround time of equipment operation 3,4 .…”

“…Using of chemical methods based on dosing of chemical compounds in production, reducing and sometimes completely preventing deposits formation is the most promising method of combating ARPD [13][14][15][16] . An inhibition degree of ARPD formation in the use of reagents ranges from 50% to 95%, while the main condition for high efficiency of the method is correct reagent selection and its dosage depending on deposits composition 4 .…”

Possibility of heated petroleum application with various additives addition as solvents for asphaltene-resin-paraffin deposits was analyzed. An object of this investigation was chosen petroleum selected from tank farm of the Kazakhstan oil refinery and samples of bottom sediments (ARPD) formed during storage in tanks. Deposits type in line with ARPD classification was identified. Additives impact on petroleum capacity in relation to ARPD was investigated. The most effective additives to inhibiting and removing bottom settlings formed in petroleum storage tanks were determined.

“…High quality cementing inevitably required regulation of the main properties of grouts using various chemicals. At the same time, grouts most frequently require correction of filtration characteristics, waiting on cement, pumpability, rheological indicators, and properties of the cement obtained [1,2].…”

Relevance of this study is concluded in the fact that high quality cementing requires regulation of the cement grouts’ properties using various chemicals. The objective of the work is based on the study of polyelectrolytes’ application efficiency used for regulation of cement slurries’ properties. In order to conduct the research the authors used the devices meeting the API requirements. Properties of cement slurry and cement were evaluated according to GOST 1581-96. In order to study the gas show emergence mechanism during the procedure of WOC (waiting on cement), the authors used a special experimental plant. It has been found that high efficiency during the research was shown by water soluble cationic polyelectrolyte (WSC-402), belonging to the class of cationic polymers. Also the paper considers its analog – cationic polyelectrolyte (PAK) released under the trade mark Praestol. Studying the mechanism of polyelectrolyte additives’ effect on cement showed that the chemicals can slow down the hydrating reaction of С3А in cement-water suspension, and prevent from the growth of gel strength of the grout, which causes drop in hydrostatic pressure of the cement grout column, provoking gas shows.
