The success of a scale inhibitor treatment depends on the placement efficiency. The scale inhibitor should be placed so that all water producing intervals accept a sufficient quantity of the total treatment volume. If significant permeability or pres

Stable water-in-oil emulsions may form during the production of crude oil, as co-produced water is mixed with the oil from reservoir to separation facilities. Such emulsions introduce technical challenges, as they must be resolved to provide the spec

This paper describes how recombination of a crude oil with various gases [N2, CO2, CH4, C2H6, and dry natural gas (NG)] influences the stability of the concomitant water‐in‐oil emulsions. The resulting separation behavior for recombined samples i

Asphaltenes separated from two different North Sea oils were studied upon addition of two kinds of naphthenic acids by employing PFG-SE NMR (pulsed field gradient-spin echo nuclear magnetic resonance) and NIR (near-infrared) spectroscopy. The results

Near-IR spectroscopy is used to follow the disintegration of asphaltene aggregates at 1,600 nm. It is shown that the technique is applicable to determine the efficiency of various additives as disaggregation chemicals.

The effect of pressure on the stability of emulsions has been studied for a recombined crude oil from the North Sea. The experiments have been conducted in a combined high pressure and temperature rig at Statoil R&D Centre. Through addition of the so

Increased oil recovery technologies are very important for the large Heidrun field located in the Norwegian Sea. Very harsh climate and stringent environmental regulations render enhanced oil recovery (EOR) projects challenging. One EOR method evalua

The Heidrun field is approaching late life production and several wells have increasing gas oil ratio caused by gas break through. Likely gas inflow is through high permeability streaks or gas cap being drawn into the wells. The Heidrun processing fa

An offshore Mid-Norway oil field includes wells on sub-sea templates at a depth of 350m. The formation waters contain up to 300 mgl−1 of barium, giving a sulphate scaling potential on seawater breakthrough. Scale protection on the template and down

In crude oil production, gas, oil, and co-produced water are mixed due to pressure drop and high shear forces as the fluid passes the wellhead and various choke valves from the reservoir to the separation facilities. The primary task at the oil prod
