Occidental Petroleum Corporation is a Houston-based oil and gas exploration and production company with operations in the United States, the Middle East, North Africa, and South America."Oxy" is one of the largest oil producers in Texas. In California, Oxy is the largest oil and natural gas producer. Oxy has additional operations in North Dakota, Colorado, and New Mexico. The company nickname began in 1964 in reference to Occidental's NYSE stock ticker . Oxy is the fourth-largest US oil and gas company, based on 2013 year-end equity market capitalization. As of 2013, the company has more than 40,000 employees and contractors worldwide.Oxy's role in oil and natural gas exploration and production, to which they have pledged a commitment to responsibility, has also been a source of criticism. The company states that it is "committed to respecting the environment, protecting safety and upholding high standards of social responsibility throughout its worldwide operations." Critics have raised concerns about Occidental's historical operations in these areas.Oxy's subsidiaries include wholly owned chemical manufacturers Occidental Chemical Corporation , OxyVinyls, and INDSPEC Chemical Corporation.

Summary Coinjecting solvent with steam under a steam-assisted- gravitydrainage (SAGD) process to reduce the required steam for production has gained importance in recent years. An extensive 2D simulation study to better understand the drainage mechanism of steam-with-solvent coinjection in the SAGD process shows that the condensation time difference of solvent and steam results in different films of gas solvent, liquid solvent, and water along the fluid interface. There is an optimal solvent-type and -concentration-ratio range for a particular reservoir and operating condition. Coinjecting the solvent at low concentration ratios can take advantage of the solvent dilution effect without losing too much heat effect from steam. In addition, this study indicates coinjection of suitable solvent mixtures may lead to better performance than injection of pure solvent in the field. © 2011 Society of Petroleum Engineers. Source

Processes for isolating 1,1,1,2,3-pentachloropropane from a crude product stream containing the 1,1,1,2,3-pentachloropropane and ferric chloride. The processes may include deep distillation of the crude, treatment of the crude with a reagent that deactivates the ferric chloride followed by distillation on the deactivated crude stream, aqueous washing of the crude product stream to remove ferric chloride followed by distillation on the deactivated crude stream. Other embodiments simultaneously prepare 1,1,2,3-tetrachloroprene and 1,1,1,2,3-pentachloroprane.

In an oxychlorination process of the type where ethylene is converted to 1,2-dichloroethane in the presence of a supported copper catalyst, the improvement comprising: the use of a supported catalyst prepared by (i) impregnating, within a first step, an alumina support with a first aqueous solution including copper, an alkaline earth metal, and an alkali metal to thereby form a first catalyst component; and (ii) impregnating, within a subsequent step, the first catalyst component with a second aqueous solution including copper and alkaline earth metal, where the second aqueous solution is substantially devoid of alkali metal, to thereby form the supported catalyst.
