... this goal, a common fact in all is the need for a great number of computationally expensive reservoir simulations, hindering extensive optimizations. This paper proposes the use of deep learning algorithms in proxy models, in order to accurately replicate the behavior of the simulator by forecasting...

..., such as microwave drying. In this scope, dielectric properties of two distinct cuttings, one obtained from clay formations and the other from reservoir, were measured in different conditions. It could be inferred from the results that the cuttings are absorbent materials and the loss tangent is directly...

... by an excitation provided by an electric field. In this sense, polar characteristics of water molecules allow quantification of volume of water present in the reservoir, independently of salinity. Owing to the shallow depths of investigation, dielectric tools are useful in evaluating residual oil in high...

...Abstract Abstract A great deal of attention has been attracted to the exploitation as well as the development of unconventional gas reservoirs, which expect to act as an essential role in counterpoising the daily increasing energy demand around the world. In this research, with the intent...

..., marginal oilfields may be transferred to be conventional ones. Since Petrobras developed the first ever offshore deep reservoir (Lula) by scale in 2006, Brazil has been conducting a progressive campaign targeting hydrocarbons buried under deep water, which contributes to discovery of Lula, Carioca, Jupiter...

... A new methodology to study naturally fracture reservoir with an induced fracture model was proposed using a representative sample of the Pre-salt reservoir. A core was cut longitudinally while the fracture was simulated using a polyoxymethylene spacer (POM). This fracture configuration...

... The disposal of drill cuttings in offshore operations has become a critical issue considering the increasing restrictions imposed by environmental legislation. When reservoir formations are reached in the drilling phase, cuttings contaminated with both drilling fluid and crude oil return...

...Abstract Abstract The high water cut 98,5% caused the abandonment of a directional well, which was reactivated after 3 years using a water shut off technique. Offset wells production behavior, stratigraphic seal layers distribution, reservoir properties, and cased hole logging data played...

... the disciplines may be required, which also contributes to the longer duration of the process. This paper proposes a framework that integrates individual simulation models of Reservoir and Flow Assurance with organizational economic premises. The framework was set to give as a result the NPV (Net Present Value...

...Abstract Abstract In the past decades, water injection development with horizontal wells is seeing more implementations and achieves considerable benefits for carbonate reservoirs in the Middle East. However, significant problems such as early water breakthrough (WBT) and uneven displacement...

... development, such as: (i) low reservoir overburden (800 m); (ii) highly unconsolidated sandstone reservoir (36% porosity and 5,000 mD permeability); (iii) heavy and viscous crude flow assurance (14°API and 228 cP at initial reservoir conditions); (iv) high naphthenic acidity oil (TAN 10 mg KOH/g); (v) high...

...Abstract Abstract The displacement of a given fluid by another in a porous media can occur either in miscible or immiscible conditions. An immiscible displacement happens, for instance, when water displaces oil in a reservoir. It can also occur when the displacing fluid is a gas...

...Abstract Abstract Atlanta is a post-salt oil field located offshore Brazil in the Santos Basin, 150 km southeast of Rio de Janeiro. The combination of ultra-deep water (1550m), heavy and viscous oil (14 API), unconsolidated sandstones, low overburden (800m), faulted reservoir rock, etc...

...Abstract Abstract Experimental data confirm that the EOR-effects observed during Smart Water flooding can be explained by wettability alteration toward more water-wet conditions. Detailed knowledge about the important crude oil – brine – rock parameters affecting reservoir wetting, fluid flow...

However, research is advancing to expand the applicability of this technique to carbonate reservoirs in a cost effective manner. In this paper, we present a comprehensive review on polymer flooding for carbonates under...

...Abstract Abstract Phased Field Development (PFD) is a well-known method to mitigate reservoir uncertainty. However, by its very nature a PFD lowers the Net Present Value (NPV) of the project compared to a Full Field Development (FFD). In this work, multiple scenarios are investigated...

A new analytical model was derived to predict of maximum achievable wellbore length (MAWL) based on the theory of buckling failure. Furui's equation for gas reservoirs was used...

...Abstract Abstract Water injection is a traditional method of secondary recovery used in the petroleum industry. Typically, even with the injection of water supplementing the initial energy of the reservoirs (primary recovery), less than 50% of the original volume of oil is produced. By altering...
