Well preparation for the CO2 injection : master's thesis

U diplomskom radu je obrađena cijelokupna prenamjena postojeće proizvodne bušotine u utisnu bušotinu za ugljikov dioksid (CO2). Priprema bušotine se sastoji od dvije osnovne operacije; pripreme za dozacjevljenje i samog dozacjevljenja. Tijekom pripreme za dozacjevljenje sanirana su oštećenja bušotine (propuštanje), te je obavljena cementacija pod tlakom (‘’skviziranje’’). Tijekom samog dozacjevljenja u bušotinu je ugrađena nova kolona zaštitnih cijevi i nova proizvodna oprema.Abstract: The main subject of this work is the recompletion of the production well into injection well. Recompletion of the well is composed out of two basic operations; the preparation for the relining and the reliningitself. During the preparation for re-lining well leakage has been fixed and secondary cementing has been done. Regarding the re-lining, a new casing column and tubing equipment has been installed
