1. n. [Drilling Fluids] Abbreviation for density, pounds per gallon, more correctly written lbm/galUS. For example, the density of water is 8.33 ppg at 60 degF [16 degC].

What does PPG mean in drilling?

In the oil industry, mud weight is the density of the drilling fluid and is normally measured in pounds per gallon (lb/gal) (ppg) or pound cubic feet (pcf) . In the field it is measured using a mud scale or mud balance.

What is LP in oil and gas?

liquefied petroleum gas (LPG), also called LP gas, any of several liquid mixtures of the volatile hydrocarbons propene, propane, butene, and butane. … LPG commonly is used as fuel for gas barbecue grills and gas cooktops and ovens, for gas fireplaces, and in portable heaters.

What is PPG unit?

Abbreviation for density unit, pounds-per-gallon (lbm/gal). For example, the density of water is 8.33 ppg at 60°F (16°C).

What is the density of drilling mud?

Normal overbalanced drilling uses a fluid density that produces about 150 psi overbalance against the bottom hole formation pressure. This may also be also expressed as ½ ppg (. 06 kg/L) overbalance.

How do you convert PPG to PSI?

Mud gradient (psi/ft) = mud weight in ppg x 0.052 Converting 10 ppg to psi/ft =0.052×10=0.52 psi/ft.

What is PPG of crude oil?

Abbreviation for density, pounds per gallon, more correctly written lbm/galUS.

How does a PPG work?

A typical PPG device contains a light source and a photodetector. The light source emits light to a tissue and the photodetector measures the reflected light from the tissue. The reflected light is proportional to blood volume variations.

What is PPG material?

Glass Reinforced Polypropylene (PPG) Temperature range: -22ºF to +194ºF (-30ºC to 90ºC)

What is the full form of PPG?

The Full Form of PPG is Points Per Game.

What is LPG and LNG?

Liquefied petroleum gas (LPG) is a mixture of propane and butane, which are gases that become liquid under pressure and can then be stored in pressurised containers (Dell and Rand, 2004). … Liquefied natural gas (LNG) consists mainly of methane.

Is LPG same as propane?

So referring to LPG as propane is accurate – they’re one and the same thing. In the United States, the name LPG isn’t in common use. Americans just call it propane.

What is meant by CNG?

Compressed natural gas (CNG) vehicles operate much like gasoline-powered vehicles with spark-ignited internal combustion engines. … Natural gas is stored in a fuel tank, or cylinder, typically at the back of the vehicle.

Why is bentonite used for drilling mud?

The most common use of bentonite is in drilling fluids. The bentonite in the flush fluid lubricates and cools the cutting tools whilst protecting against corrosion. As the drilling fluid generates hydrostatic pressure in the borehole, it hinders fluid and gas penetration.

Why is mud weight important in drilling?

1. n. [Drilling Fluids] Mud weight controls hydrostatic pressure in a wellbore and prevents unwanted flow into the well. The weight of the mud also prevents collapse of casing and the openhole. Excessive mud weight can cause lost circulation by propagating, and then filling, fractures in the rock.

What is the difference between ECD and EMW?

Equivalent Circulating Density: Definition: ECD is defined as the EMW (hydrostatic) value plus friction pressure. Unlike EMW, ECD calculations can be applied to a single fluid such as drilling mud being pumped through a wellbore.

What is light gas oil?

Light Gas Oil is the liquid petroleum distillates heavier than naphtha, with an approximate boiling range from 401 to 650 °F that contains mostly C8~C15 hydrocarbons, lowering the kerosene flow rate.

What is API in fuel?

The American Petroleum Institute gravity, or API gravity, is a measure of how heavy or light a petroleum liquid is compared to water: if its API gravity is greater than 10, it is lighter and floats on water; if less than 10, it is heavier and sinks. … It is used to compare densities of petroleum liquids.

How is SG calculated from API?

The formula for API gravity is API = (141.5/SG) -131.5 where SG is the specific gravity of the petroleum liquid being measured. For example, for an API gravity of 50, add 131.5 to obtain 181.5. Divide 141.5 by (131.5 + API gravity) to obtain the specific gravity of the oil.

How many psi are in a gallon?

What is ppg metric?

PPG is an important metric in basketball that signifies the number of points gained per game by a player. … These professional players prove their basketball prowess on the court as they rack more points than others.

What is specific gravity of mud?

As an example, a 17.5 lb/gal mud has a specific gravity of 2.1. To determine the weight of 1 bbl of barite, determine the density of 1 bbl of pure water and multiply the result by the specific gravity of barite.

What kind of company is PPG?

PPG is a global manufacturer of paints, coatings, and specialty materials and a Fortune 200 company with headquarters in Pittsburgh and operations in nearly 70 countries around the world.

What brands do PPG own?

Globally the brands include PPG Paints, Olympic paints and stains, Glidden paints as well as Sico paints and stains.

Who is PPG owned by?

Area servedWorldwideKey peopleMichael H. McGarry (Chairman & CEO)

What is ECG and PPG?

ECG (electrocardiography) sensors measure the bio-potential generated by electrical signals that control the expansion and contraction of heart chambers. PPG (photoplethysmography) sensors use a light-based technology to sense the rate of blood flow as controlled by the heart’s pumping action.

Where can PPG be measured?

Sites for measuring PPG PPGs can be obtained from transmissive absorption (as at the finger tip) or reflection (as on the forehead). In outpatient settings, pulse oximeters are commonly worn on the finger.

Is PPG a power signal?

The spectrum illustrates peaks at the fundamental frequency of 50 Hz as well as the second harmonic at 100 Hz. Photoplethysmography (PPG) is used to estimate the skin blood flow using infrared light.

What is PNG and CNG?

The only difference between CNG and PNG is the form of delivery. CNG comes out of natural gas bottles whilst PNG comes out of a pipe. Both are refined natural gas with methane being the primary constituent.

Which is better LNG or CNG?

Liquid gas can be 600 times denser than it was after extraction. … The process of creating LNG is more expensive, so the price of LNG is higher than CNG, but it is a great opportunity to transport natural gas over long distances effectively. Without pipelines, LNG is a great alternative as a power source.

What is PNG in gas?

LPG is Liquefied Petroleum Gas and PNG is Piped Natural Gas. LPG is supplied in liquid form just as the name suggests in cylinders whereas PNG is supplied through a pipeline. LPG is used as a fuel in heating appliances and vehicles, where as PNG is used for cooking (gas stoves) and heating water (gas geysers).
