Abstract

Hidrauličkim frakturiranjem nastoji se premostiti pribušotinsko oštećenje stvaranjem pukotine visoke vodljivosti. Na taj način omogućen je lakši dotok fluida iz ležišta u bušotinu, što će za posljedicu imati povećanje proizvodnosti bušotine. Uspješnost hidrauličkog frakturiranja ovisi o pravilnom odabiru bušotine za fakturiranje. Izbor odgovarajućeg fluida ovisi o ležišnoj temperaturi, ležišnom tlaku te vrsti ležišne stijene. Smještaj odgovarajuće koncentracije i vrste podupirača u pukotini ključan je za uspješno frakturiranje. Vodljivost, poluduljina i visina frakture, najvažniji su parametri stvorene frakture. U radu je opisan primjer hidrauličkog frakturiranja na plinsko-kondenzatnom polju X.

Abstract (english)

Hydraulic fracturing is performed to bypass the near wellbore damage by creating a high conductivity fracture. Thanks to the created fracture, fluid flow from the formation to the wellbore is improved and that will result with an increased well productivity. Hydraulic fracturing efficiency depends on the selection of a right candidate. The selection of the fracturing fluid depends on reservoir temperature, reservoir pressure and the type of the reservoir. Placing the right concentration of proppant and the right type of proppant is of key importance for a successful hydraulic fracturing treatment. An example of hydraulic fracturing in a gas-condensate reservoir is described in this thesis.
