Oilfield Chemicals

The petroleum industry includes the global processes of exploration, extraction, refining, transportation and marketing of natural gas, crude oil and refined petroleum products. The oil industry demands more sophisticated methods for the exploitation of petroleum. As a result, the use of oil field chemicals is becoming increasingly important and has received much attention in recent years due to the vast role they play in the recovery of hydrocarbons which has enormous  commercial benefits. The three main sectors of the petroleum industry are Upstream, Midstream and Downstream. The Upstream deals with exploration and the subsequent production (drilling of exploration wells to recover oil and gas). In the Midstream sector, petroleum produced is transported through pipelines as natural gas, crude oil, and natural gas liquids. Downstream sector is basically involved in the processing of the raw materials obtained from the Upstream sector. The operations comprises of refining of crude oil, processing and purifying of natural gas. Oil field chemicals offers exceptional applications in these sectors with wide range of applications in operations such as improved oil recovery, drilling optimization, corrosion protection, mud loss prevention, drilling fluid stabilization in high pressure and high temperature environment, and many others. Application of a wide range of oilfield chemicals is therefore essential to rectify issues and concerns which may arise from oil and gas operational activities. This review intends to highlight some of the oil field chemicals and  their positive applications in the oil and gas Industries.

Organic Chloride

The organic chloride content in crude oil being among the most crucial quality characteristics of the crude is strictly controlled. The presence of organic chlorides in crude oil greatly endangers the oil refineries since it causes a severe equipment corrosion. Specialty oilfield chemicals, which are widely used in the crude oil extraction, transportation, refining and storage, could be a source of the crude oil contamination with organic chlorides. As a consequence, the organic chloride content determination in the chemicals is required. It was demonstrated that the organic chloride content in the specialty oilfield chemicals can be determined by X-ray fluorescence spectrometry (XRF) using an appropriate specimen preparation procedure. Two specimen preparation procedures, i.e. the solvent extraction and the distillation of a specimen mixed with the crude oil or its model, were tested. It was established that an organic chloride content can be successfully determined in a broad range of the specialty oilfield chemicals by the XRF technique when applying these specimen preparation procedures. The investigation of four types of the specialty oilfield chemicals confirmed that the specimen preparation procedure, involving a solvent extraction of organic chlorides from the chemicals into isooctane, is more comprehensive than the distillation procedure since it is free from the limitations associated with the use of high temperatures.

High Inhibition

Nitrone has drawn great attention due to its wide applications as a 1,3-dipole in heterocyclic compounds synthesis and the bioactivities. With the special structure, nitrone can also be used as ligand in inorganic chemistry. Based on the current research, the nitrones are anticipated to be effective inhibitors against acidic and microbial corrosion. The aim of this work is to investigate the inhibitory action of nitrones. In this work, a series of phenyl nitrone derivatives (PN) was synthesized and used as acidic and microbial corrosion inhibitors. The results indicate that several compounds show moderate to high inhibition efficiency (IE) in 3% HCl. Accompanied with HMTA or BOZ, the IEs greatly increase, and the highest efficiency of 98.5% was obtained by using PN4 + BOZ. Investigation of the antibacterial activity against oilfield microorganism shows that the nitrone derivatives can inhibit SRB, IB, and TGB with moderate to high efficiency under 1,000 mg/L, which makes them potential to be used as bifunctional oilfield chemicals.
