What is low specific activity scale?

What is low specific activity scale?

LSA scale (Low Specific Activity scale) is a radioactive deposit inside pipes and other production equipment and consists of carbonates and sulphates of Ca, Ba and co-precipitated Ra. • The salts were dissolved in the reservoir itself in a mixture of original formation water and injected seawater.

Where are norms found?

Naturally occurring radiative material (NORM) is material found in the environment that contains radioactive elements of natural origin. NORM primarily contains uranium and thorium (elements that also release radium and radon gas once they begin to decay) and potassium.

What is LSA in oil and gas?

Abstract. The origin of the NORM waste (LSA Scale) in the oil industry is the formation of sulphate and carbonate precipitates inside tubulars and other production equipment during oil production.

What are the activities of oil and gas industry?

Oil and gas sector comprise three main activities – upstream (exploration and production), midstream (transportation and processing1) and downstream (distribution and sale to end users/consumers).

What is LSA norm?

‘Naturally Occurring Radioactive Material’ (NORM) or ‘Low Specific Activity’ (LSA) are the collective names for these naturally occurring radioactive substances which may be released during the production of oil and natural gas.

What does NORM stand for?


Acronym Definition
NORM Normal
NORM Naturally Occurring Radioactive Material
NORM National Organization of Restoring Men
NORM Not Operationally Ready, Maintenance (US DoD)

How do you calculate norms?

A measure of exposure from X-ray and gamma ray mR/hr radiation in air. Measurement of the intensity of radiation in air. A microroentgen = one millionth of a roentgen. A measure of the radioactivity of one gram of radionuclide that decays at a rate of 3.7E-2 disintegration per sec.

What is radioactive LSA?

Low Specific Activity (LSA) material means radioactive material with limited specific activity which is nonfissile or is excepted under § 71.15, and which satisfies the descriptions and limits set forth in the following section.

What are the steps in oil production?

The seven steps of oil and natural gas extraction

  1. STEP 1: Preparing the Rig Site.
  2. STEP 2: Drilling.
  3. STEP 3: Cementing and Testing.
  4. STEP 4: Well Completion.
  5. STEP 5: Fracking.
  6. STEP 6: Production and Fracking Fluid Recycling.
  7. STEP 7: Well Abandonment and Land Restoration.

What are LSA and norms related to?

What type of radiation is NORM?

Radioactive materials
Radioactive materials which occur naturally and where human activities increase the exposure of people to ionising radiation are known by the acronym ‘NORM’.
