... based on or required by the activities of microorganisms" (1). Aerobic and anaerobic metabolic pathways biotransform and destruct various classes of hydrocarbons. There are many applications of biotechnology in the fossil fuel industry from enhanced oil recovery to environmental remediation. Benefits...

... Abstract Conventional upgrading of petroleum distillates requires catalysts, high temperatures and high pressures to hydrogenate and cleave fused-ring aromatic hydrocarbons to give alkyl benzenes. A potential alternative is to use bacteria in a two-stage upgrading process: first, bacteria...

... of a storage tank it would support the growth of that portion of the "dormant"microbial population which could use gasoline hydrocarbons as a source of cell carbon and energy. This potential for gasoline degradation however can only be fully expressed if conditions are suitable for growth. Therefore...

... Abstract Remediation of contaminated soil, particularly flare pits, in oilfield sites has become a focus of increasingly stringent environmental legislation. These earthen pits consist of soil mixed with hydrocarbons, water, salts, and metals. Current remediation techniques such as biological...

... of the world. As a reservoir driven technology, one is attempting to recover more hydrocarbons by correctly applying modern drilling techniques. In this regard the underbalanced drilling has moved into phase 2 of the evolution process where instrumentation and control both downhole and at surface have become...

... exploration companies strive to obtain good prospect properties, explore for hydrocarbons, find those hydrocarbons and profitably produce the hydrocarbons in an environmentally and operationally safe manner. Oilfield service companies provide products and services that help the oil and gas exploration...

.... The four conditions were: intrinsic bioremediation, where the soil received only water; biostimulation with one application of slow release fertilizer; bioaugmentation with one application of both fertilizer and a psychrotrophic (cold-adapted), hydrocarbon-degrading bacterial culture...

.... The field logistics and the field test results are presented in this paper. Introduction Most hydrocarbon-bearing (oil and gas) sandstone reservoirs contain clay materials, which have the tendency to swell in contact with water-based foreign fluids or to migrate due to fluid velocity in the pore spaces...

... Abstract A systematic methodology which combines inflow performance analysis, production forecasting, and economic considerations is presented for optimum recovery of hydrocarbons from naturally fractured reservoirs using horizontal well technology. An analytical method for predicting...

... determine the source of well production, hydrocarbon or water, to allow remedial workovers. Although well testing is common in nearly all reservoirs, the testing of sour gas wells and horizontal wells is still a significant challenge for operators and service companies alike. The testing ofsour wells has...

... pressure) are pure CO 2 and blended CO 2 containing up to about 12 mol% CH 4 or 5 mol% N 2 . The wellhead gas from Steelman gas plant requires further enrichment (with CO 2 or hydrocarbon gases) to become a suitable EOR agent for southeast Saskatchewan reservoirs. Introduction The majority of light...

... Abstract The main aim of well log interpretation is to determine the reservoir geological and petrophysical properties downhole as well as properties fluids and their distributions in a reservoir, and identification of hydrocarbon from well logs is the most important job. Neural networks...

.... This is best illustrated by Figure 1 which shows the distribution of hydrogen/carbon (H/C) ratios for various hydrocarbons. The important numbers for us are oil sands bitumen and heavy oils at 1.5, conventional light crudes and synthetic crude at 1.6 to 1.7 and transportation fuels at 1.9 to 2.0. Somewhere...

... Abstract A unified treatment of materials balance computations to estimate hydrocarbons in place is presented. This method generalizes the normal procedures for gas reservoirs to all fluids of interest to the petroleum industry. We show that a plot of average pressure divided by a two-phase...

... problems. Product Description It is a well known and documented fact that bacteria will metabolize hydrocarbons. However, the metabolic pathways of hydrocarbon degradation are not completely understood. It is known that alkenes can be oxidized resulting in the generation of several intermediate and end...
