Thermal recovery methods within catalytic aquathermolysis is a new promising exploitation approach in extracting heavy oil and natural bitumen. In this technology, the catalyst is added in a stage of injecting high-temperature steam. At the pay zone, three types of reactions takes place: thermolysis, reaction of high temperature steam and catalysis. As a result, the injected steam changes to water transferring its heat to rocks across the interface. Thus, the interfaces of catalyst solutions and hot rocks are cruc...

Extra-heavy oil is considered as one of alternative energy sources mainly because of reserve potentials, rich in organic compounds and rare transition metals like V and Ni. Extraction from this hydrocarbon resource has always been a challenge due to high oil viscosity and as a result low mobility within porous media. Conventionally the production from extra-heavy oil reservoirs is achieved by thermal methods such as SAGD, CSS, Insitu combustion, etc. However, these techniques do not consider the post productionsпї...

Up to date the high content of toxic and corrosive compounds in petroleum gas is one of the main problems. Hydrogen sulfide, a gray carbon monoxide, carbon disulphide, mercaptans; sulfides and disulfides in gas condensates are the most often appeared among the sulfur-containing impurities. This problem can be solved by creation new technological methods for preparation of oil-dissolved gas or development existing ones. Hydrogen sulfide has a high corrosion activity, and the existence of water in the gas increases ...
