Elemental sulfur (S8) is often present in considerable amounts in sour gas reservoirs at the reservoir conditions (pressure and temperature). For the isothermal conditions in the reservoir, the reduction in reservoir pressure below a critical value will cause the elemental sulfur to deposit in the formation. Sulfur deposition can cause severe loss in the pore space available for gas, and in tur...

Thermal recovery involves well-known processes such as steam injection (cyclic steam stimulation, steam drive, and steam-assisted gravity drainage), in situ combustion, and a more recent technique that consists of heating the reservoir with electrical energy. When high frequency is used for heating, it is called electromagnetic (EM) heating. The applications of EM heating for heavy-oil reservoi...

We present results from an experimental study of the decoherence and decay of quantum states of a trapped atomic ion’s harmonic motion interacting with several types of engineered reservoirs. We experimentally simulate three types of reservoirs: a high-temperature amplitude reservoir, a zero-temperature amplitude reservoir, and a high-temperature phase reservoir. Interaction with these environm...

the karkheh dam reservoir with a capacity of more than 5 billion cubic meter is the largest dam in iran with both agricultural and drinking usages. its hydrodynamics and water quality were modeled and simulated to analyze the total maximum daily load (tmdl) of total dissolved solids (tds). the simulation was supported with measurements of temperature and tds measurements during two years. a lat...

background: dams are one of the most important manmade buildings to provide of drinking water. in order to manage of water quality in dams reservoirs, the recognition of phenomena that occurred in it is essential. thermal stratification is one of the major problems that decrease the water quality of dam. the aim of this study was to investigate thermal stratification of ekbatan dam (hamadan) as...

In experimental sciences, random processes often place a fundamental limit on the achievable measurement resolution. A well known example is the Johnson noise voltage across a resistor. In this paper, we describe observations of the spontaneous transfer of heat in two equilibrium systems: one consisting of a thermometer linked to a reservoir, the other consisting of two thermometers connected t...

Understanding and controlling the mechanisms that determine the efficiency of photoelectric devices is of fundamental importance in the quest for efficient and clean sources of energy. Thermodynamically speaking, these devices are driven by the temperature difference between a hot reservoir sun, temperature Ts and a cold reservoir earth, ambient temperature T . Therefore, like any heat engine, ...

A simple urn model is presented that may describe heat engines employing as working agents spin2 particles (e.g., electrons) or twolevel atoms. In this model the cold reservoir is an urn located at altitude ǫc that contains N balls of total weight nc. Likewise, the hot reservoir at altitude ǫh contains N balls of total weight nh. A cycle consists of exchanging two randomly selected balls betwee...

Selective withdrawal from a thermal stratified reservoir has been widely utilized in managing reservoir water withdrawal. Besides theoretical analysis and numerical simulation, model test was also necessary in studying the temperature of withdrawn water. However, information on the similarity theory of the withdrawn water temperature model remains lacking. Considering flow features of selective...
