Product Index

The relationship between the flowrate (Q) towards the well and the pressure drawdown is approximately linear, and is defined by the productivity index (PI). 

The increased exposure to the reservo/r results from the long horizontal sections which can be attained (between 500m and 1000m horizontal section is now common). Because the productivity index is a function of the length of reservoir drained by a well, horizontal wells can give higher productivities in laterally extensive reservoirs. As an initial estimate of the potential benefit of horizontal wells, one can use a rough rule of thumb, the... 

Drawdown and build-up surveys are typically performed once a production well has been completed, to establish the reservoir property of permeability (k), the well completion efficiency as denoted by its skin factor (S), and the well productivity index (PI). Unless the routine production tests indicate some unexpected change in the well s productivity, only SBHP surveys may be run, say once a year. A full drawdown and build-up survey would be run to establish the cause of unexplained changes in the well s productivity. 

The previous sections have considered the flow of fluid to the wellbore. The productivity index (PI) indicates that as the flowing wellbore pressure (Pwf) reduces, so the drawdown increases and the rate of fluid flow to the well increases. Recall... 

From downhole pressure drawdown and build-up surveys the reservoir permeability, the well productivity index and completion skin can be measured. Any deviation from previous measurements or from the theoretically calculated values should be investigated to determine whether the cause should be treated.

As the protective barrier between the body and the external environment, the skin is exposed to potentially damaging chemicals on a daily basis. It has been estimated that approximately 80,000 chemicals are in common use worldwide [5] and new products are being continuously introduced. Chemical production for most countries increased in 2004 with an increase in the total production index for all chemicals of 2.9% in the United States, 4.3% in the United Kingdom, and 6.8% in Canada [6], As new products are being developed and chemical production increases, toxicologists are faced with the need to develop improved methods for evaluating the potential of these chemicals to induce contact dermatitis. 

The probability that chance alone accounts for the progressive increase in relative risk as the animal product index increases is 0.002. 

A score of 1,2, or 3 was respectively assigned to 3 categories which reflect increasing use of each of four animal products (meat, eggs, milk, and cheese). For each subject, the scores for these 4 animal products were summed to obtain the animal product index. ...

Products Index (CPI) database. To aid in reducing the size of a hit list, a Reagent Selector user can filter reagents and sort on properties, availability, presence or absence of functional groups, etc. (Fig. 9.18). Further list reduction can be achieved by clustering the structures by means of a cluster analysis using substructure keys as descriptors.
