Sand Production in Oil & Gas Wells: A Growing Industry Challenge
The issue of sand production in oil and gas wells is a well-known and growing problem for producers in the industry. The erosion caused by sand during production can lead to significant challenges, damaging downstream equipment (e.g. valves and chokes) within relatively short periods.
Furthermore, the accumulation of sand deposits in production separators can disrupt production, causing liquid carry-over into other equipment. To address these issues, implementing online monitoring and active desander systems is essential.
Otherwise, the presence of an uncontrollable amount of sand, combined with an unregulated production rate, can lead to severe integrity consequences at a later stage, including:
- Loss of containment due to wall loss.
- Mismeasurement.
- Equipment failure or damage caused by sand erosion.
- Incomplete or insufficient liquid separation due to reduced residence time resulting from sand build-up in the vessel.
- Loss of optimum production.

Sand Assessment (SA)
Sand Assessment (SA)
A detailed analysis to determine the sand source through a non-invasive portable sand sensor and monitor for sand transition. Here, state-of-the-art sand scanners are used to deduce the sand profile accumulated in the process vessels.
Sand Recovery (SR)
Sand Recovery (SR)
We perform sand recovery with CFD simulation, which enables an effective separation liner due to its cyclonic liner design. With excellent erosion resistance and up to 95% separation efficiency, our innovative CFD simulation offers a significantly better outcome than the typical OEM’s Cyclone Separator.
Sand Treatment (ST)
Sand Treatment (ST)
Ensuring full compliance with PETRONAS Guidelines on produced sand disposal, we utilise TermoRens chemicals for safe and effective sand treatment. Proven to be environmentally friendly, TermoRens chemicals kill bacteria and Legionella in water systems without affecting other materials.
Sand Management System – FAQ
A sand control system in the oil and gas industry is used to prevent the migration of sand and other solid particles from the reservoir into the wellbore. It is crucial because sand production can lead to various issues, such as:
- Equipment damage
- Reduced well productivity
- Operational challenges
Offshore sand control technology incorporates two well-established oil and gas techniques: hydraulic fracturing and gravel pack completions.
Hydraulic fracturing involves injecting a high-pressure fluid into the wellbore to create fractures in the reservoir rock. When applied to sand control, it can create channels in the reservoir that facilitate the controlled flow of oil and gas while minimising sand production.
On the other hand, gravel pack completions place specially sized gravel particles in the space between the wellbore and the reservoir formation. This gravel acts as a physical barrier, preventing sand grains from entering the wellbore while allowing fluid flow.
The best offshore sand control method depends on various factors such as reservoir characteristics, production conditions, and operational requirements. Some commonly used offshore sand control methods include:
- Gravel packing
- Sand screens
- Inflow Control Devices (ICDs)
