Overview of Reservoir Simulation by Prem Dayal Saini
Reservoir simulation is the study of how fluids flow in a hydrocarbon reservoir when put under production conditions. The purpose is usually to predict the behavior of a reservoir to different production scenarios, or to increase the understanding of its geological properties by comparing known behavior to a simulation using different geological representations.

Abstract: This work is devoted to CO2 Huff-n-Puff studies on heavy oil. Oil recovery for heavy oil
reservoirs is sufficiently small in comparison with conventional reservoirs, and, due to the physical
limitation of oil flow through porous media, a strong need for better understanding of tertiary
recovery mechanisms of heavy oil exists. Notwithstanding that the idea of Huff-n-Puff gas injection
technology for enhanced oil recovery has existed for dozens of years, there is still no any precise
methodology for evaluating the applicability and efficiency of this technology in heavy oil reservoirs.
Oil recovery factor is a question of vital importance for heavy oil reservoirs. In this work, we repeated
Huff-n-Puff tests more than three times at five distinct pressure points to evaluate the applicability
and efficiency of CO2 Huff-n-Puff injection to the heavy oil reservoirs. Additionally, the most critical
factor that affects oil recovery in gas injection operation is the condition of miscibility. Experimental
data allowed to distinguish the mixing zone of the light fractions of studied heavy oil samples.
The experimental results showed that the pressure increase in the Huff-n-Puff injection process does
not affect the oil recovery when the injection pressure stays between miscibility pressure of light
components of oil and minimum miscibility pressure. It was detected that permeability decreases
after Huff-n-Puff CO2 tests.

1. Introduction
The continuous increase in energy consumption [1] enhances the total demand for every type of
hydrocarbon resource [2,3]. Despite the very challenging production of oil from heavy oil reservoirs,
heavy oil is becoming a very prospective and valuable source of energy these days. Combined with
the facts that (1) oil production from conventional reservoirs is decreasing [4], (2) tremendous heavy
reserves are more than 3 times bigger than conventional oil reserves [5], and (3) tertiary oil recovery
techniques are advancing each year [6,7], we predict that more and more studies about heavy oil will
be published in the upcoming years.

Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

CW RADAR, FMCW RADAR, FMCW ALTIMETER, AND THEIR PARAMETERSveerababupersonal22
It consists of cw radar and fmcw radar ,range measurement,if amplifier and fmcw altimeterThe CW radar operates using continuous wave transmission, while the FMCW radar employs frequency-modulated continuous wave technology. Range measurement is a crucial aspect of radar systems, providing information about the distance to a target. The IF amplifier plays a key role in signal processing, amplifying intermediate frequency signals for further analysis. The FMCW altimeter utilizes frequency-modulated continuous wave technology to accurately measure altitude above a reference point.
2. 1. INTRODUCTION
Reserves are those quantities of petroleum which are anticipated to be
commercially recovered from known accumulations from a given date forward.
All reserve estimates involve some degree of uncertainty.
The uncertainty depends mainly on the amount of reliable geologic and engineering
data available at the time of the estimate and the interpretation of these data.
The relative degree of uncertainty may be conveyed by placing reserves into one of
two principal classifications, either proved or unproved .
Unproved reserves are less certain to be recovered than proved reserves and may be
further sub-classified as probable (2P) and possible (P10) reserves to denote
progressively increasing uncertainty in their recoverability.

4. 1. INTRODUCTION
Estimating hydrocarbon reserves is a complex process that involves integrating geological and
engineering data. Depending on the amount and quality of data available, one or more of the following
methods may be used to estimate reserves:
• Volumetric
• Material balance
• Production history
• Analogy
Volumetric estimates of OOIP and OGIP are based on a geological model that geometrically describes the
volume of hydrocarbons in the reservoir. However, due mainly to gas evolving from the oil as pressure and
temperature are decreased, oil at the surface occupies less space than it does in the subsurface. Conversely, gas
at the surface occupies more space than it does In the subsurface because of expansion. This necessitates
correcting subsurface volumes to standard units of volume measured at surface conditions.

8. RECOVERY FACTOR (RF)
The basic equation to calculate recoverable oil reserves is
Recoverable Oil reserves = OOIP x RF
Where, RF = Recovery Factor = RFp + RFs
RFp is primary recovery which depends on drive mechanism
RFs is secondary mechanism = EDxEAxEV
ED is Displacement efficiency
EA is Areal sweep efficiency
EV is vertical sweep efficiency

The recovery factor (RF) is typically higher than for oil reservoirs; it is often
near unity for dry gas reservoirs.
