Sand Jet Systems

In addition to dissolved components and dispersed hydrocarbons, produced water often contains a mixture of solids. These originate primarily from the reservoir rock but may include sand, clay, mineral scale and, possibly, proppant.

The bulk of the produced solids will accumulate in the primary gravity oil-gas separator vessel, from which they must be removed periodically to avoid reduction of the separator residence time, and reduced separation efficiency. Eventually, the solids can accumulate to considerable depths, and increased carry-over into the downstream processes will be observed. This problem is also associated with slug catchers and free water knock-out drums.

Advantages of Sand Jet systems:

  • Online operation
  • Cost effective
  • Low water requirement.

Application of Sand Jet systems:

  • Mainly horizontal separators (vertical separators also possible).

Case Studies

Bouri-GUP (Libya)

Located 120 kilometers (70 miles) north of the Libyan coast in the Mediterranean Sea, the Bouri Offshore Field is a joint venture between Eni Oil and the National Oil Corporation of Libya. It is considered one of the largest producing oilfields in the Mediterranean and consists of Satellite Platform (DP3), Main Production Platform (DP4), - gas was flared at both - plus a permanently moored storage tanker (FSO).
