Abstract

Although hydraulic fracturing has been used for many decades, in recent years its taking a much bigger interest of companies around the world. With hydrocarbon reserves depleting every year the need for production from unconventional reservoirs increases. Therefore, the application of the hydraulic fracturing simulation method has enabled production from such reservoir types and thus provided a new momentum in the oil and gas industry. With the huge contribution that hydraulic fracturing provides to the production of hydrocarbons from unconventional reservoirs, there is no need to neglect either the great added value that this technology provides in numerous projects run on conventional oil and gas reservoirs. This thesis will follow an onshore exploration well which was a project from a Croatian oil company. The well confirmed existence of gas and gas condensate in projected volumes but due to low permeability of reservoir it was not possible to produce economically. The decision was made to improve production by implementing hydraulic fracturing stimulation. Which allowed a successful resumption of exploration project, whose initial unsatisfactory results did not provide sufficient basis for putting the well in production. Every part of the project will be analysed with possibility of revealing and improving any aspect. The main focus will be on hydraulic fracturing part of the project and evaluation of production performance which was expected with the one attained from hydraulic testing.
