Abstract
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.
Highlights
Major petroleum companies operating in the Persian/Arabian Gulf, regardless of the relative low and fluctuating oil prices, have the intention of increasing their oil production and even doubling it in the few years

Summary
Major petroleum companies operating in the Persian/Arabian Gulf, regardless of the relative low and fluctuating oil prices, have the intention of increasing their oil production and even doubling it in the few years. The companies are putting great efforts on reducing the operational cost of the ongoing development projects and they are looking for a proven income by investing in mature oil field revitalization These projects are undergone by drilling new infill wells, drilling sidetracks from existing wells, workovers with massive matrix acid stimulations, drilling and completion of power water injection wells with surface water treatment facilities and the drilling and intelligent completion of subsea natural dump flooding wells. Water flooding is one of the most common secondary oil recovery methods for reservoir pressure support in partially depleted oil and gas fields (Subhi et al, 2011). Since formation water is used for dump-flood, water compatibility is usually not an issue, it does not require any treatment or processing prior to injection inside the formation (Abdulhadi et al, 2019)
