This is similar to the methods used for microchip manufacture. The basic component of the device is a small channel 500 by 40 micrometers in cross section designed to hold a sand-column upto 1mm in length. We have fabricated the device from sodalime glass so that it is chemically resistant and can tolerate high temperatures. The footprint of the device is 8 by 2 cm. Fluids are flown through a single channel of the device by positive displacement using syringe pumps During an experiment glass beads are introduced to the device prior to a 10 000 cp oil being emplaced. Water is circulated. The volumes of different fluids flowing through draining wells is recorded from video-stills. Use of chemical additives for HO-EOR A number of methods have been developed for heavy oil production, a subset of these use chemical additives to modify the properties of the water phase to enhance oil recovery. These generally involve making the water phase more viscous (so that it better displaces oil) and mobilising the oil (by surfacting oil in water or unbonding oil from the host formation). In this situation the key question is how much more oil can be recovered by a specific volume of the additive and will this be economic? Apart from field trials the only way to answer this question is to perform core-flood experiments. However these are difficult to set up and run because they require considerable resources and expertise. Unfortunately the information provided by these experiments is key to the basic Evaluation and Management of a heavy oil reservoir.

Viscosity of crude/ petroleum products by Say-bolt
This document describes how to use a Saybolt viscometer to determine the viscosity of crude petroleum products. It explains that the Saybolt viscometer measures the time it takes for 60cc of a sample fluid to flow through a calibrated orifice under controlled temperature conditions. The longer it takes, the higher the viscosity. The procedure involves preheating the sample, filtering it into the viscometer, stirring to the test temperature, then rapidly removing the stopper to start the timer as the fluid flows to a graduated flask below. The efflux time in seconds is then used to calculate the sample's viscosity in Saybolt universal seconds or centistokes.
Septictankprocessdesign
Domestic septic tanks are underground concrete structures that hold wastewater from homes long enough for solids to settle and be broken down by bacteria. They consist of compartments to prevent sludge and scum from exiting, and effluent flows into a drain field. Septic tanks are designed based on detention time (12-36 hours typically) or rational methods considering settling, digestion and sludge storage zones. Effluent can be disposed of via soak pits, trenches, or irrigation. Septic tanks require periodic cleaning to remove accumulated sludge but provide inexpensive wastewater treatment for small communities if properly maintained.
3. grit chamber
- Grit chambers are used to remove grit (heavy inorganic solids like sand and gravel) from wastewater to protect equipment.
- There are three main types of grit chambers: horizontal flow, aerated, and vortex. Horizontal flow uses gravity settling, aerated uses air to create spiral flow, and vortex uses tangential inflow to induce a vortex.
- Grit chamber design considers the settling velocity and size of grit particles. Parameters like detention time, number of units, flow velocity, and loss of head are also designed.
- Cleared grit is collected manually or mechanically, then disposed of through dumping, burying, or landfilling. Odorous grit should be buried.

Application of Thermal Methods for Heavy Oil.pdf
This document discusses various thermal methods for recovering heavy oil, including cyclic steam stimulation (CSS), steam flooding, in situ combustion (ISC), steam-assisted gravity drainage (SAGD), vapor extraction (VAPEX), and emerging technologies. CSS involves alternating cycles of steam injection, soak time, and production from each well to reduce viscosity and produce heavy oil. SAGD uses horizontal well pairs with steam injected into the upper well to heat the formation and produce heavy oil from the lower well. VAPEX uses solvents instead of steam to reduce viscosity. The document analyzes the application of these methods, their effectiveness in different reservoir conditions, and their use worldwide in heavy oil production.
Aade 07-ntce-18 LIFUBRWIBV
This paper discusses a single-phase microemulsion technology for cleaning oil- or synthetic-based mud filter cakes in a single step. Laboratory tests showed that microemulsions incorporating oil, surfactants, brine and acid could solubilize oil-based mud, make filter cake solids water-wet, and remove acid-soluble particles in one treatment. Sandpack and filtration cell tests demonstrated the microemulsions restored over 90% of original water injection permeability after cleaning oil-based mud filter cakes. The single-phase microemulsion technology allows efficient filter cake clean-up in a single step compared to traditional multiple step methods.

IRJET - Removal of Oil Spillage in Marine Environment using Grooved Type Cyli...
This document describes the design and testing of an oil skimmer with a grooved cylindrical drum to improve oil recovery efficiency. It discusses how existing skimmer designs have low recovery rates and outlines the key parameters for an efficient skimmer. The proposed design uses a polypropylene drum with U-shaped grooves to maximize surface area and enable nearly 100% of adhered oil to be removed. Testing of a fabricated prototype in an oil/water tank demonstrated it could effectively recover oil and control slick thickness. Analysis showed recovery efficiency increased with drum rotation speed up to a point and higher groove depth allowed more oil collection.
Enhanced Oil Recovery
Electro-treatment is a new enhanced oil recovery method that uses electrical pulses to open new pathways for oil to flow out of aging wells. It requires portable, low-cost equipment and little energy. Initial treatments show increased oil production of 10-30% over the next 2-5 years, compared to other expensive EOR methods. The technology was developed in Russia and has been successfully tested on hundreds of wells in Russia and other countries. It works by using micro-explosions caused by the electrical pulses to break up tight spaces in the reservoir and allow more oil to flow through.
Estimating the Amount of Moisture Content in Crude Oil Samples
Abstract :- Determination of the amount of water in crude oil and petroleum products has always been important. Rather than paying crude oil prices for water, contracts have been based on "net dry oil". This is calculated by reducing the total gross standard volume (GSV) by the amount of water and sediment present as determined by analysing a sample of the oil. Accurate analysis for the water content is usually more difficult than the determination of gross volume, temperature, and gravity of the oil.

It provides an overview of alkaline flooding and discusses how alkalis work on a chemical level to improve oil recovery through mechanisms like emulsification, wettability alteration, and chemical precipitation. The contents section lists the various topics that will be covered in the document related to alkaline injection characteristics, mechanisms of action, figures, tables, and
Improving oil recovery in fractured reservoirs
The document discusses improving oil recovery in fractured reservoirs. It aims to investigate oil production in fractured reservoirs and understand recovery mechanisms. The key recovery mechanisms are fluid expansion, capillary imbibition, diffusion, and gravity-controlled displacement. Primary recovery typically recovers 20% of oil using reservoir drive mechanisms. Secondary recovery such as water injection recovers 25-35% by maintaining pressure. Tertiary or enhanced oil recovery (EOR) methods can recover 20-30% more. Common EOR methods discussed for fractured reservoirs include miscible gas injection (CO2, nitrogen), thermal recovery (steam flooding, fire flooding), and chemical recovery (polymer flooding, alkaline flooding). Case studies show methods like steam flooding and nano
Improving Oil Recovery In Fractured Reservoirs (Eor)
The aim of this project is to investigate the oil production in fractured reservoirs and to have an understanding of recovery mechanisms and all the methods that lead to improvement of the production in fractured reservoirs especially the EOR processes and to determine the advantages and limitations of fractures during EOR process.
EOR Methods
EOR methods involve injecting various substances into oil fields to increase the amount of oil extracted. Primary recovery uses natural reservoir pressure to extract 5-10% of oil. Secondary recovery injects water or gas to extract an additional 25-30% of oil. Tertiary recovery injects different materials like steam, CO2, polymers or surfactants to extract another 20-30% of oil remaining after primary and secondary recovery. The three main EOR categories are thermal, gas, and chemical injection. Thermal injection uses heat to reduce oil viscosity while gas injection uses gases like CO2, nitrogen or natural gas to increase oil recovery. Chemical injection uses polymers, alkali or surfactants to improve oil mobility.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
