What is Pickett plot?


A Pickett plot is a method used in petrophysical analysis to evaluate formation characteristics of conventional, granular reservoirs. The method provides a graphical solution to Archie’s equation to determine water saturation of a reservoir by plotting resistivity versus porosity on a log-log scale.

Moreover, What is Archie equation?

Sw = [ (a / Fm)*(Rw / Rt) ](1/n) Sw: water saturation. F: porosity. Rw: formation water resistivity.

Secondly, How do you calculate saturation in water?

Water saturation is the ratio of water volume to poreporeVoid fraction is defined as the ratio of the volume of the gaseous phase occupied in a channel to the total volume of the channel.www.sciencedirect.com › topics › engineering › void-fractionVoid Fraction – an overview | ScienceDirect Topics volume. Water bound to the shaleshale1. adj. [Geology, Shale Gas] Containing shale, a fine-grained, fissile, detrital sedimentary rock formed by consolidation of clay- and silt-sized particles into thin, relatively impermeable layers. It is the most abundant sedimentary rock.www.glossary.oilfield.slb.com › Terms › shalyshaly | Oilfield Glossary is not included, so shale corrections must be performed if shale is present. We calculate water saturation from the effective porosityeffective porosityEffective porosity is most commonly considered to represent the porosity of a rock or sediment available to contribute to fluid flow through the rock or sediment, or often in terms of “flow to a borehole”.en.wikipedia.org › wiki › Effective_porosityEffective porosity – Wikipedia and the resistivity log. HydrocarbonHydrocarbonHydrocarbon, any of a class of organic chemical compounds composed only of the elements carbon (C) and hydrogen (H). The carbon atoms join together to form the framework of the compound, and the hydrogen atoms attach to them in many different configurations.www.britannica.com › science › hydrocarbonhydrocarbon | Definition, Types, & Facts | Britannica saturation is 1 (one) minus the water saturation.

Simply so, What is cementation factor?

The cementation factor, m, indicates reduction in the number and size of pore openings or reduction in the closed-off (dead-end) channels.

What is the saturation point of water?

The saturation point describes a point in water where the water cannot hold any more of a particular chemical, causing any extra material to remain suspended in the pool water.

How do you calculate saturation temperature?

So, if you are able to determine the pressure at any of these points (evaporator, condenser, or receiver), you can easily determine the “saturation” temperature by finding the measured pressure on the P-T card and reading the corresponding temperature.

What is saturation process?

Saturation means holding as much moisture as possible. When you water your houseplants, you may soak them until the soil around each plant reaches saturation. The noun saturation means the act of completely soaking something until it’s absorbed as much water as it can.

What is saturated temperature of refrigerant?


What is point of saturation in economics?

Meaning of saturation point in economics. It’s a point where a product has not more demand in market and due to competition, decreased need, obsolescence, or some other factor. This time company either diversifies some change in product or again launches in market or start marketing of new product.

What is the saturation temperature of r134a?

Saturation Properties – Temperature Table (20°C – 101.06°C) Saturation Properties – Pressure Table (60 kPa – 3 MPa) Superheated Vapor Properties – (0.06 MPa – 0.24 MPa) Superheated Vapor Properties – (0.28 MPa – 0.7 MPa)Oct 9, 2010

What is the saturation pressure of water?

760 mmHg is equivalent to 101325 Pa. A value of 130 mmHg is quite a high vapour pressure if we are talking about room temperature. Water’s saturated vapour pressure is about 20 mmHg at this temperature.

What temperature is saturated steam?

Example: The temperature of 250 psig pure steam is always 406°F. Heat of Saturated Liquid (Column 4). This is the amount of heat required to raise the temperature of a pound of water from 32°F to the boiling point at the pressure and temperature shown.

What is the saturation temperature of water at 100 kPa?

What is a good superheat for 134a?

Superheat for most systems should be approximately 10F measured at the evaporator; 20F to 25F near the compressor. If the suction pressure is 45 psi, (which converts to 22F) and the suction temp is 32F, the system still has 10F of superheat.

What is a saturated system?

Saturated Definition #1 This chemistry definition refers to a saturated compound. A saturated substance is one in which the atoms are linked by single bonds. A fully saturated compound contains no double or triple bonds. Alternatively, if a molecule contains double or triple bonds, it is considered to be unsaturated.
