الملخص EN

Oil and gas production and processing operations sometimes cause naturally occurring radioactive materials (NORM) to accumulate at elevated concentrations in by-product waste streams.

The sources of most of the radioactivity are isotopes of 238U and 232Th series, which are naturally present in the subsurface formations from which oil and gas are produced.

NORM waste may cause problems in the operations of installations by plugging perforations, clogging tubular and valves then restricting flow.

Therefore, plants or equipment have to be refurbished and decontaminated before re-used to avoid radioactive waste or surface contaminated object.

There are two options for safe disposal of scale and sludge produced from NORM Descaling Facility (NDF) : 1- Injection into an abandoned production well.

2- The construction of a near surface depository.

These options are assumed to be environmental friendly disposal options.
