SUMMARY Removal of an intact, inflated tissue expander can result in uncontrolled spillage of expander contents on the drapes, surgeons, staff, or patient. The technique described has been used for the past 4 years to eliminate these spillage concerns. It is simple and inexpensive using common disposable supplies found in any operating room. An irrigating syringe is modified by cutting away its...

A typical Iranian carbonate matrix block surrounded by an open fracture was modeled in order to understand the fracture-matrix interaction and realize how to model the interaction best. The modeling was carried out by using a fine-scaled Eclipse model in the single porosity mode (the fractures were explicitly modeled). The model was extended to a stack of 6 matrix blocks to understand block-to-...

Few people would deny that the world runs on oil. Oil, regarded as the blood of industry, may cause economic crises, and even lead to conflicts and wars. Three applicable models and several feasible policies are presented to settle the problem. We devise the Irreversible Depletion Model, and use global statistics data in logistic regressions to predict the total ultimate oil recovery. Relying o...

Microbial enhanced oil recovery (MEOR) is an economical method used to improve the oil recovery from reservoirs. In the MEOR techniques, by applying different microorganisms, a variety of products such as bioacid, biogas, biosurfactant, and biopolymer are generated, among which biosurfactant, one of the important metabolites, is produced by bacteria. It is worthy to note that bacteria are suita...

In this study, a chemical additive made by a combination of polymer, alkaline, and silica nanoparticles is used to control the oil recovery and relative permeability curves. Various parametersincluding the type and concentration of polymer, alkaline, and nanosilica particles have been studied.To evaluate the efficiency of these additives, we performed unsteady state displaceme...

Oil spills from offshore drilling and coastal refineries often cause significant degradation of coastal environments. Early oil detection may prevent losses and speed up recovery if monitoring of the initial oil extent, oil impact, and recovery are in place. Satellite imagery data can provide a cost-effective alternative to expensive airborne imagery or labor intensive field campaigns for monit...

Oil companies typically abandon stripper wells with production rates below 15 barrels per day because the and maintenance cost exceed pumping rate. spillage is primary cause of low rates; an example such failure Oloibiri oil well in Nigeria. During peak operation, flow rate was 5,100 1960 abandoned due to declining The site has 18 drilled wells, only 17 can be classified as well. Because Nigeri...

The objective of this work was to evaluate and compare the potential polyurethane kapok (Chorisia speciosa) residues as sorbent materials in treatment diesel spillage. To determine sorption capacity, gravimetric tests were performed static medium at room temperature different temperatures (10, 15 28 °C) varying time contact between material diesel. It observed that process occurs a high velocit...

abstract the present study was carried out to investigate the efficacy of two anesthetics, clove oil and ketamine, comparison of hematological parameters, and blood biochemical indices under optimum doses of the two anesthetics in juvenile sterlet acipenser ruthenus (n=276) with an average weight of 64.1 ± 3.4 g. clove oil was used in concentrations of 14, 35, 56, 77, 98 and 119 mg/l, and those...
