What does a weight indicator do?
The weight indicator is the principal means by which the equipment operator monitors the function of downhole tools and equipment. Factors such as fluid density, which affects buoyancy and wellhead pressure, also impact the forces measured at surface.
What does a scale measure?
A scale or balance is a device to measure weight or mass. These are also known as mass scales, weight scales, mass balances, and weight balances. The traditional scale consists of two plates or bowls suspended at equal distances from a fulcrum.
How does a scale measure work?
Scales measure how much something weighs—and they do it by measuring how much force exists between the object you’re weighing and planet Earth. The heavier the object, the more gravity pulls it down, and the more it stretches the spring.
What are the 3 types of weighing scale?
3 Types of Weighing Scales and How They Work
- Strain Gage Load Cells. This design has become the industry standard over the last half a century.
- Force Motor Scales.
- Ultra Precision Scales: SAW Technology.
How weight on bit is calculated?
The weight of the drilling assembly is controlled and measured while the drill bit is just off the bottom of the wellbore. Then, the drill string is slowly and carefully lowered until it reaches the bottom. This measured weight includes everything that exerts tension on the drill string.
What is Hookload?
1. n. [Drilling] The total force pulling down on the hook. This total force includes the weight of the drillstring in air, the drill collars and any ancillary equipment, reduced by any force that tends to reduce that weight.
How do digital scales work?
A digital scale works best on a flat surface. When an object is placed on a digital scale, its weight causes its internal strain gauge to deform. The scale converts that amount of deformation to an electrical signal, runs the signal through a digital converter, and shows the weight on the scale’s display.
How do you read digital scales?
How To Read Digital Scale Grams
- In weighing a certain item, make sure that you place your digital scale on a leveled surface.
- After that, place the item on the platform of your scale to measure it.
- Finally, once the measurement displayed in your digital scale settles, read your measurement.
Where are scales used?
As mentioned, scales are often used to weigh larger masses, such as raw materials, reagents, and products in a production setting. However, they may be used in commercial or household settings to weigh smaller masses, such as produce in a grocery store, or ingredients for baking.
What are the 4 types of scales?
The four types of scales are:
- Nominal Scale.
- Ordinal Scale.
- Interval Scale.
- Ratio Scale.
What is oil and gas ROP?
ROP stands for “Rate of Penetration,” which is basically how fast the bit is drilling the hole. Average ROP is generally measured by taking the total distance drilled divided by the time it took to drill it. In drilling, instantaneous ROP usually refers to the maximum, real ROP through an interval or formation.
What is the purpose of a scale indicator?
What is a scale indicator? A scale indicator, also known as a weight indicator or a digital weight indicator, provides the weight data from a scale to the operator. Many indicators also serve as scale controllers, which tell a machine when and how to execute certain processes, such as dosing or filling, based on the reading from the scale.
What is the goal of an industrial scale?
The goal of any industrial scale is to determine an accurate weight for items placed on the scale platform. While this goal may be common to all scales, the level to which it is achieved, the method in which it is achieved, the ease of doing so, and the use of the results vary widely …
