The use of downhole continuous chemical injection (DHCI) has become common in Equinor, with around 30-40 % of new wells being equipped with DHCI in the last decade. Scale inhibitor supply accounts for around three quarters of the installations. A rou

Calcium carbonate (CaCO3) scale formation in production wells and process systems is a well-known challenge in the oil and gas industry. Various strategies are selected to prevent scale formation (proactive, e.g. by scale inhibitors) or to remove sca

In offshore enhanced oil recovery (EOR) applications polymer residence time within the reservoir could be many years. Long term stability (preservation of solution viscosity) within the anaerobic reservoir is a fundamental property of the polymer che

In offshore enhanced oil recovery application polymer residence time within the reservoir could be many years. Accelerated laboratory methods, for chemical stability testing, are therefore desired to perform efficient product type screening. For high

SummaryWe believe that osmosis has been overlooked as a possible mechanism for observed low-salinity enhanced-oil-recovery (EOR) effects. Osmosis can occur in an oil/water/rock system when injecting low-salinity water, because the system is full of a

Polymer injection for viscous oil displacement has proven effective and gained interest in the recent years. The two general types of EOR polymers available for field applications, synthetic and biological, display different rheological properties du

When EOR by polymer flooding is applied in the offshore environment, polymer can be expected to face long reservoir retention times of up to several years. The stability and viscosity retention of the polymer needs to be evaluated throughout this tim

Injection of alkaline water can potentially yield large amounts of calcium naphthenates in the reservoir. This can cause a problem if the precipitate moves through the reservoir and accumulates in the near well bore or the production system. The obje

Breakthrough of alkaline water from one producing zone mixing with formation water and oil from a different zone could potentially give severe calcium naphthenate scaling. In this scenario pre-equilibrated formation water and oil mix with alkaline wa

Monoethylene glycol (MEG) is a gas hydrate inhibitor. The large amounts used in gas field industry impose the need for MEG regeneration. During this process the water–MEG mixture is heated at low pressure to remove most of the water. It is importan
