Water control additives are chemicals or materials placed into a formation to reduce or shut off unwanted water production without significantly impairing hydrocarbon flow. Sand control additives are materials used to prevent the production of formation sand and fines from unconsolidated or weakly consolidated reservoirs. Scale control additives are chemicals that dissolve the existing scale deposits or prevent the formation of scale deposits in the near-wellbore formation, downhole tubing, and surface facilities. Key additives include:
| Gelling and Plugging Agents |
| Stabilizers and Stabilizer Aids |
| Crosslinkers, Activators and Delaying Agents |
| Resin Consolidation Agents |
| Coupling and Tackifying Agents |
| Scale Inhibitors and Scale Dissolvers |
| Relative permeability modifiers, Surfactants and Solvents |

Gelling and Plugging Agents
-
Gelling and plugging agents play crucial roles in preparation of water control treatment fluids such as crosslinked organic or inorganic gels.

Stabilizers and Stabilizer Aids
-
Aqueous-based gel formed from synthetic polymer and organic crosslinkers will degrade especially at elevated temperature. Stabilizers or stabilizer aids are used to improve the high-temperature stability of the water control treatment fluids.

Crosslinkers, Activators and Delaying Agents
-
Rigid gels are required to shut off the water in naturally fractured or fissured reservoirs. Crosslinkers, activators and delaying agents are the key additives to prepare these rigid gels.

Scale Inhibitors and Scale Dissolvers
-
Inorganic scales, organic scales, scales mixtures are detrimental to well performance. Scale dissolvers, inhibitors are therefore used in oilfield chemical treatment to eliminate or prevent the adverse effects of scales on oil or gas well performance.

Surfactants and Solvents
-
Wax or asphaltene deposits introduce various well production problems including the composite scales (organic and inorganic) in wellbore, matrix or gravel packs and organic deposits around downhole tools, tubulars or other well equipment. Special surfactants and solvents are developed to resolve the problems introduced by the above organic or mixed scales.
