“…More reasonable values can be obtained by treating the different subgroups separately (Table 2, 3 and 4) and combining them with the historical trends in giant oilfield behaviour. When it comes to the average decline rates of giant oilfields, our results end up in the same range as CERA (2007) andIEA (2008). This is discussed in more detail in Höök et al (2008).…”

The giant oil fields of the world are only a small fraction of the total number of fields, but their importance is huge. Over 50% of the world oil production came from giants by 2005 and more than haft of the worlds ultimate reserves are found in giants. Based on this it is reasonable to assume that the future development of the giant oil fields will have a significant impact on the world oil supply.In order to better understand the giant fields and their future behaviour one must first understand their history. This study has used a comprehensive database on giant oil fields in order to determine their typical parameters, such as the average decline rate and life-times of giants. The evolution of giant oil field behaviour has been investigated to better understand future behaviour. One conclusion is that new technology and production methods have generally lead to high depletion rate and rapid decline. The historical trend points towards high decline rates of fields currently on plateau production.The peak production generally occurs before half the ultimate reserves have been produced in giant oil fields. A strong correlation between depletion-at-peak and average decline rate is also found, verifying that high depletion rate leads to rapid decline. Our result also implies that depletion analysis can be used to rule out unrealistic production expectations from a known reserve, or to connect an estimated production level to a needed reserve base.

“…Most of the world's giants have also reached maturity and many of these fields are subject to measures to increase recovery (Babadagli, 2007). Drilling of new wells and installation of more equipment can delay the actual onset of decline for some years, but once that oil field starts to decline the decline is faster.…”

“…Depending on the type of a field, petrophysical and fluid properties, history of its production, we can choose one of the above methods, or use both at once. Every hydrocarbon reservoir is specific so it is important to consider all available method and choose properly one of them, following by the criteria of selection the optimal revitalization method [1]. Figure 1 shows the general distribution of revitalization methods.…”

“…Every field has a specific production curve over which production grows to a peak level and then declines until it reaches the point at which operation is no longer economic. Revitalization extends the natural decline curve to provide an economic profits from hydrocarbon production [1,6].…”

“…In EOR operations a range of chemicals are used, e.g, injection of alkaline solutions, polymers, surfactants, as well as combinations of these [1][2][3][4][5][6]. Other techniques use low salinity water, foam, nanoparticles that react to block larger pores and microbial reactions MEOR (see [7,8] for recent reviews). One of the challenges in EOR-operations is to quantify the potential for producing remaining oil and to evaluate the effect of EOR measures, often done using pilot studies.…”

Abstract. In enhanced oil recovery (EOR), chemicals are injected into the oil reservoir, either to increase macroscopic sweep efficiency, or to reduce remaining oil saturation in swept zones. Tracers can be used to identify reservoirs that are specifically suited for EOR operations. Injection of a selection of partitioning tracers, combined with frequent sample analysis of produced fluids, provides information suited for estimation of residual oil saturation. Tracers can also be used to evaluate and optimize the application of EOR chemicals in the reservoir. Suitable tracers will follow the EOR chemicals and assist in evaluation of retention, degradation or trapping. In addition to field applications, tracers also have a large potential as a tool to perform mechanistic studies of EOR chemicals in laboratory experiments. By labelling EOR chemicals with radioactive isotopes of elements such as H, C and S, detailed studies of transport mechanisms can be carried out. Co-injection of labelled compounds in dynamic flooding experiments in porous media will give information about retention or separation of the unique compounds constituting the chemical formulation. Separation of such compounds may be detrimental to obtaining the EOR effect expected. The paper gives new information of specific methods, and discusses current status for use of tracers in EOR operations.
