Abstract (english)
In the process of oil reservoir waterflooding, natural water dump flood technology for reservoir pressure decline prevention is considered as an unconventional but technically less demanding, more economical and safer method in comparison to surface power water injection. With natural dump flood technology, a single well serves as a water producer from a water bearing layer (aquifer) and simultaneously through gravity and the pressure difference between the aquifer and the depleted oil reservoir, it serves as a water injector inside the oil reservoir without expensive and complex injecting water treatment facilities at the surface. With the use of such technology and the running of intelligent well completion, it allows for the permanent monitoring of water production, injection rates and temperature inside the chosen reservoir. In addition, in offshore operations, the use of a subsea wellhead with a mud line suspension system allows for the placing of the injector well at the best predetermined position for water injection in a targeting reservoir and, together with an efficient subsurface acoustic data acquisition system, leads to better reservoir management and well integrity improvement. The overview and critical reflection of the drilling and intelligent completion of a natural dump flooding well for reservoir pressure support in partially depleted oil reservoirs in the Persian/Arabian Gulf has been given, referring to both their preparation and execution phase. The possibility of applying natural water dump flood was also considered in the Croatian onshore Beničanci oil field through a pilot project of water injection into the Be-62 well.
Abstract (croatian)
U postupku zavodnjavanja ležišta nafte radi podržavanja tlaka prirodno zavodnjavanje ležišta smatra se nekonvencionalnim, ali zato tehnički manje zahtjevnim, ekonomičnijim i sigurnijim u usporedbi s metodom utiskivanja vode s površine. Tehnologija prirodnoga zavodnjavanja podrazumijeva upotrebu iste bušotine za proizvodnju vode iz vodonosnoga sloja te simultano, s pomoću djelovanja gravitacije i razlike slojnih tlakova u vodonosnome sloju i djelomično iscrpljenome naftnom ležištu, utiskivanje vode u naftno ležište bez izgradnje skupih i kompleksnih površinskih sustava za utiskivanje. Primjenom najsuvremenije tehnologije i vođenjem tzv. inteligentnoga opremanja bušotine omogućeno je stalno praćenje proizvodnje vode, kapaciteta utiskivanja i temperature unutar odabranoga ležišta. Osim toga, u odobalnim operacijama korištenje podvodne bušotinske glave sa sustavom za privremeno napuštanje bušotine omogućava najbolji položaj za utiskivanje vode u ležište i zajedno sa sustavom za prikupljanje podataka vodi do boljega upravljanja ležištem i poboljšanja integriteta bušotine na odabranome naftnom polju. U ovome radu dan je pregled i kritički osvrt na bušenje i inteligentno opremanje bušotina prirodnoga zavodnjavanja ležišta u djelomično iscrpljenim ležištima nafte u Perzijskome zaljevu, a odnosi se i na fazu pripreme bušotine i na samo izvođenje. Dan je i primjer mogućega korištenja tehnologije prirodnoga zavodnjavanja ležišta na hrvatskome (kopnenom) naftnom polju Beničanci koji je u visokome stupnju iscrpljenosti.
