Capillary suction-timers
This document describes an experiment to evaluate the capillary suction time (CST) test for measuring sludge dewaterability. The objectives were to evaluate alternative test apparatus designs and procedures to improve precision and reduce costs. The CST test measures the time for filtrate to travel between electrodes using a filter paper under suction. Variables tested included funnel geometry, filter paper type, stirring, temperature, and sludge concentration. The results could help recommend improved CST test methods and better understand relationships between CST and other sludge dewaterability tests.
mud filtration
1) The document summarizes an experiment to measure the static filtration behavior of a water-based mud. Key measurements taken include the volume of mud filtrate collected after 30 minutes and the thickness of the resulting filter cake.
2) The experiment involves placing a mud sample in a filter press cell between two rubber gaskets and a filter paper. Pressure is applied and the volume of filtrate is measured over 30 minutes.
3) Results showed a mud cake thickness of 3mm and filtrate volume of 25ml. The document discusses factors like the purpose of rubber gaskets and screens, how mud cakes form in real wells, and advantages of mud cakes.
Improving the strength of concrete
This document analyzes the effect of replacing sand with glass powder at ratios of 5%, 10%, and 20% on the compressive strength of concrete mixtures at water-cement ratios of 0.50, 0.55, and 0.58. Testing was conducted after 7, 14, and 28 days. Results showed that concrete with a 0.50 water-cement ratio maintained strength regardless of glass content, as did mixtures with 0.55 ratio and 20% glass. The study concludes that flat glass powder can be used to replace sand to produce structurally sound, environmentally-friendly concrete, though fluidity and void content require further study.
Drilling Lab - Mud Filtration
This experiment aimed to determine the filtration rate of mud under 90-100 psi pressure using a standard API filter press. Mud was prepared using water and bentonite and tested in the filter press, which applied pressure for 30 minutes. The mud formed a 4 mm thick cake and 18.7 cc of filtrate was collected. Temperature affects viscosity and filtration rate, so should be reported. The experiment showed how mud cake thickness and filtrate volume can be measured under controlled pressure and temperature using a filter press.
Physical test of cement
This document outlines various physical tests conducted on hydraulic cement, including normal consistency, setting time, fineness, soundness, compressive strength, and specific gravity. It describes the test methods, equipment, and precautions for each test according to Indian Standards. Maintaining proper temperature, humidity, and equipment calibration is important. All tests should be performed following the specified standards.
Helum porosty meter
This experiment aims to determine porosity using a helium porosimeter. The student, Kamal Abdurahman, will conduct the experiment supervised by Mr. Ali Kamal. The helium porosimeter works by measuring the volume of helium gas that expands into sample pores based on Boyle's and Charles' laws. This allows direct measurement of grain volume and pore volume, from which porosity and grain density can be derived. The apparatus includes a helium porosimeter, pressure gauge, and various sample holders to accommodate different sized rock plugs and cores.
Mud Filtration Test
This document discusses mud filtration experiments. It aims to monitor the rate of fluid loss from a filter press under controlled conditions and measure the thickness of residue deposited on the filter paper. Filtration properties are important for understanding invasion into porous formations and filter cake buildup on wellbores. The experiment uses a standard filter press to test mud samples under static and dynamic filtration conditions at varying temperatures and pressures. Results like fluid loss volume and filter cake thickness indicate how much water/oil wetting and permeability damage may occur in formations. Formation damage can reduce productivity and is affected by factors like filter cake properties, filtrate invasion, and drilling/completion operations.

This document describes an experiment to measure the sand content in drilling mud using a sand content kit. The objectives are to determine the volume percentage of sand-sized particles (>74 μm) in the mud. The procedure involves adding mud and water to the sand content tube, shaking, pouring onto a screen, and measuring the volume of sand collected. Periodically measuring sand content is important because high levels can cause issues like increased filtration or interference with downhole tools. The sand content kit provides a simple method compared to other analysis techniques. Safety precautions and maintenance of equipment are also outlined.

SMHL profile
The Soil Mechanics & Hydraulics Laboratory in Karachi was established in 1956 by USAID to conduct soil mechanics and geotechnical investigations. It has 54 employees including engineers and technicians. The laboratory performs various soil, concrete, aggregate, cement, and steel tests according to ASTM and AASHTO standards. It also conducts geophysical surveys and pile installation. The laboratory works with both public sector organizations like irrigation departments and private sector clients on projects including buildings, roads, towers, and barrages.
Sampling techniques
1. Sampling of minerals involves collecting portions of rocks or ores to determine their quality and composition. There are different types and methods of sampling depending on whether it is done above or below ground.
2. Common sampling methods include grab sampling, channel sampling, chip sampling, and drill hole sampling. Grab sampling involves collecting rock specimens while channel sampling cuts channels across rock faces.
3. Sampling seeks to provide a representative sample of the whole deposit but can be subject to random and systematic errors from factors like improper spacing, insufficient samples, or incorrect analysis. Proper sampling techniques aim to minimize these errors.
Dilution
1. The aim of the experiment was to reduce the mud's density through dilution by adding water. This reduces the hydrostatic pressure.
2. Procedures involved mixing bentonite and water to create mud, then adding additional water to dilute the mud. Density measurements before and after dilution showed a reduction from 8.58 ppg to 8.45 ppg.
3. Mud dilution with fresh water is not effective for field drilling or acceptable for drilling shale formations, as fresh water can damage shale through swelling. Other methods like adding bentonite or barite are required to control mud density and pressures.
Drilling Lab - Sand Content
This document summarizes an experiment conducted by Muhammad Sulaimon Rasul to determine the percentage of sand-sized particles in a drilling fluid sample using sand content equipment. The experiment involved preparing a water-based mud using bentonite and barite, then measuring its density. The sand content equipment was used to separate sand-sized particles from the mud sample by filtering. The percentage of sand was then read directly from the graduated measuring tube of the equipment. The results showed a sand content of 5% for the tested water-based mud sample.

PENETRATION TEST ON BITUMINOUS MATERIALS.
This document describes a penetration test performed on bituminous materials to determine consistency. The test involves vertically penetrating samples of the material with a standard needle under controlled conditions and measuring the penetration distance. Bitumen is characterized based on penetration grades like 30/40 and 40/50, with higher values indicating softer consistency. The document outlines the test apparatus, sample preparation process, testing procedure, and results, noting a mean penetration value of 37.37mm for the tested sample.
Drilling Lab - Mud Dilution
This document describes an experiment to create drilling mud with different densities by diluting an initial mud sample. The experiment aims to lower the density of an initial mud sample from 8.8 ppg to 8.7 ppg by adding a calculated volume of water. The procedure involves creating an initial mud sample, measuring its density, adding a calculated volume of water, and measuring the density of the diluted mud. The results show errors in the final densities compared to the targets, likely due to inaccuracies in measuring or adding the water volumes. The document concludes that performing these types of experiments helps students learn how to create and dilute drilling muds as required for different well conditions.
Summer Project Poster - 802116
This document summarizes a study that used particle image velocimetry (PIV) to analyze the velocity profiles of glass beads in a glass cell during withdrawal. Water and glass beads were filled in the cell and mixed with magnetite to facilitate PIV analysis. PIV analysis found that the particle velocity profile fit a Gaussian model over time. The standard deviation of the Gaussian was found to depend on both the withdrawal time and position in the glass cell. While the study provided interesting results, further work is needed to better reproduce the conditions proppants experience during hydraulic fracturing.

Dye Penetrant Test
Dye penetrant testing is a non-destructive testing method that uses dye penetrant and developer to locate surface-breaking defects in non-porous materials like metals and plastics. The process involves applying penetrant, removing excess penetrant, and applying developer to make any defects visible. Ultrasonic thickness inspection and radiographic testing are also common non-destructive testing methods. Non-destructive testing allows inspection without damaging the test object.
Mud weight and density test ex.no(1)
1. This document describes an experiment to test mud weight and density. The aim is to understand how to use a mud balance apparatus and how density changes when barite is added to water.
2. The procedure involves calibrating the mud balance with water, mixing bentonite mud, measuring its density, adding barite, and remeasuring density. Calculations are shown for determining mud component volumes and weights.
3. Results found the initial bentonite mud density was incorrect due to poor mixing. Adding barite increased density as expected to control hydrostatic pressure and prevent fluid influx from formations. Limitations like dirty equipment and inexperienced users could impact results.

This document describes a test method for determining the shrinkage limit of soils. Key points:
- The test involves compacting a wet soil sample into a small dish, then slowly drying it to a constant mass to determine the moisture content at which no further volume change occurs upon drying.
- The dried soil pat is coated in wax to prevent water absorption, then its mass is measured both in air and submerged in water to calculate its volume.
- The shrinkage limit is the moisture content where the soil reaches its minimum volume, below which further drying does not cause shrinkage. It indicates the soil's shrinkage and cracking potential.

Analysis for predicting the Input Interactions of HBF Performance at -10 μm P...
This document summarizes an analysis of factors influencing the performance of a Hyper Baric Filter (HBF) used to treat iron ore fines. Experiments were conducted using a 3^3 full factorial design to examine the effects of vessel pressure, snap blow, and filter disk rotation on moisture reduction and material throughput. Linear regression models were developed for each response and validated. Vessel pressure had the greatest effect on moisture reduction, explaining over 80% of the variation, while vessel pressure, disk rotation, and their interaction most influenced throughput. The models can predict HBF performance within the required level of confidence.

Non destructive testing
Non-destructive testing (NDT) refers to a group of analysis techniques used to evaluate materials, components, or systems without causing damage. Common NDT methods include liquid penetrant testing, magnetic particle testing, and ultrasonic testing. Liquid penetrant testing uses a dye that is drawn into surface-breaking flaws by capillary action and visualized. Magnetic particle testing magnetizes a part and uses iron particles to indicate areas of magnetic flux leakage from subsurface flaws. Ultrasonic testing uses high frequency sound waves that reflect off internal flaws and interfaces, with the reflections analyzed to detect and characterize imperfections.
