SAND MANAGEMENT

Overview

Sand Management is a philosophy on the prediction of production of sand, silt, fine from reservoir, estimate its impact to the integrity of sub-surface completion and surface facilities. The compelling impact it has on production can be multi-prong from the necessity to restrict production to combat severe erosion, decline of the production due to blockage of fines at pore space and gravel pack/screen and failure due to damage to the screen & gravel pack.

Sand production can be often restricting the production of hydrocarbon and poses operational issues in handling the facility, leading to increased OPEX and reduced revenue. If not appropriately controlled and managed can become HSE threat especially when operating aged facilities. Sand production can become part and of parcel of operating the matured field. Hence, it is important to understand the production of sand and devise suitable way to minimise the production and remove it from production system.

At RLS we continuously innovate to bring the solutions to market to address these issue. Our in-house offering SandPROTM, robust and field proven cyclone solid separation system can be installed at wellhead or pipeline to remove sand up to 10 micron at minimum of 90% removal efficiency at very affordable leasing or ownership cost.

We also provide custom study, formulation, supply and deployment of subsurface chemical sand consolidation technology (Powelgel series- PowelSANDTM) to compliment or even as an alternative to gravel pack or screens when situation demand for. We offer this solution together with our technology partner PowelTec, France. The solution is designed with negating any potential side effects it may cause in hydrocarbon production from well and safe for operation. In fact, additional benefit of reduction of water production and relative permeability improvement are packaged with the product for improved hydrocarbon recovery.

MULTIPHASE DESANDER CYCLONE SOLIDS-SEPARATION TECHNOLOGY (SANDPRO)

Uncontrolled sand production poses a major problem for oil & gas operations. It costs operators billion of dollars in loss of production and high facilities maintenance costs.

The risk of production loss can be eliminated by installing a continuous sand/solid separation system. This can be applied near the source of sand production i.e. at wellhead or upstream of production separator vessel.

Removing these solids at or near the wellhead (upstream of the process facilities) offers a number of advantages:

  • Protects equipment from erosion damage
  • Prevents solids build up in vessels and pipelines
  • Prevents sand damaging valve seats
  • Overall risk reduction to on production
  • Reduces the need for vessel entry

The SandPRO Cyclone solids-separation package removes sand from multi-phase well streams applicable for all gas liquid ratios from 100% liquid 100% gas. The SandPRO are engineered to ensure maximum operating envelope and separation efficiency.

CHEMICAL SAND CONSOLIDATION (POWELSAND)

POWELGEL-PowelSANDTM is a new technology using microgels with different sizes, which is new proposed on the market by Reservoir Link. The main domains of applications are:

  • Water Shutoff/Conformance control
  • Sand control

The process uses performed water-soluble microgels, produced in the plant and delivered under liquid (emulsion) or power form. POWELGEL-PowelSANDTM have a remarkable thermal (up to 165⁰C), shear and chemical stability, a narrow size distribution and environmentally friendly (some have been qualified for offshore North Sea applications).

When injected into a formation, POWELGEL-PowelSANDTM adsorb strongly on the rock, thus forming a thick continuous gel-like on pore walls, which improves rock stability and induces RPM effects (Relative Permeability Modification). Actually, POWELGEL-PowelSANDTM can strongly reduce the relative permeability to water, while affecting very little the relative permeability to oil or to gas. They can thus be bull-headed into the whole open interval surrounding the wellbore, with very little risk of well impairment.
