Stage development

In the pre-development stage, core samples can be used to test the compatibility of injection fluids with the formation, to predict borehole stability under various drilling conditions and to establish the probability of formation failure and sand production. 

Petroleum economics is used at exploration, appraisal and development stages of the field life, to help to make the following typical decisions ... 

As of this writing, hybrid probe immunoassays are primarily in the laboratory development stage. Assays using the technology have been developed... 

Conjugated-Diene Butyl. CDB can be obtained by the controlled dehydrohalogenation of halogenated butyl mbbet (27). This product concept remains in the development stage. 

Unlike polyurethane-RIM processes, nylon-RIM reactions are endothermic and require temperatures of 130-140°C. In contrast to the polyurethane-RIM systems, this enables thick wall parts to be made. Cycle times of 2-3 minutes are comparable to those for polyurethane-RIM. In the development stage, current work is concerned with reducing moulding times and optimising moulding conditions. 

Creative thinking is important not only in new process development, but also in continually reviewing and reevaluating existing processes for opportunities to make the process inherently safer. Many of the tools and techniques discussed in Section 4.2, on Research, are useful in the process development stage as well. It is appropriate to revisit the basic chemistry to study alternate options. 

As the process moves from the process development stage to the design and construction stage the chemistry, unit operations, and type of equipment have been set. The design and construction stage needs to focus primarily on equipment specifications, piping and instrumentation design, installation details, and layout for an inherently safer installation. 

During the inherent safety review, at the design development stage, identify potential human factors/ergonomics issues that should be addressed by the design team. 

As noted in Step 13 of the inherent safety review at the design development stage, the team reviews the process to develop a list of potential ergonomics/human factors issues. This list provides input to the design team so that these issues can be addressed as the design progresses. 

Relativistic methods can be extended to include electron correlation by methods analogous to those for the non-relativistic cases, e.g. Cl, MCSCF, MP and CC. Such methods are currently at the development stage. ... 

One of the significant drawbacks of multidimensional analytical methods is the specificity of the conditions of each separation mode for a particular sample type, together with restrictive requirements for the type and operational conditions of the interface between them. Therefore, extensive work in the method development stage, along with the availability of highly skilled personnel for operating such systems, are required. 

Although the preparation of the quite complex selector modules prior to the synthesis of the library represented a rather significant synthetic effort, this study showed clearly the potential of combinatorial chemistry in the early development stage of a chiral separation medium and demonstrated a novel approach to rapid screening that might be amenable to full automation in the future. 

Over the past decades, advances have been made that reduce environmental impacts of coal burning in large plants. Some arc standard and others experimental. Limestone (mainly calcium carbonate) scrubber smokestacks react with the emitted sulfates from the combustion and contain the chemical products, thereby reducing the release of SO., into the atmosphere by a large factor (of ten or more). Pulverization of coal can also allow for the mechanical separation of some sulfur impurities, notably those in the form of pyrites, prior to combustion. Currently deployed—with more advanced versions in the development stage—are various t yies of fluidized bed reactors, which use coal fuel in a pulverized form, mixed with pulverized limestone or dolomite in a high temperature furnace. This technique reduces sulfate release considerably. There are... 

Resource economics stresses that, to date, experience is that the conversion of unutilized resources to profitable ones has moved ahead of demand growth and resource commodity prices have fallen over time. Moreover, M. A. Adehiian s classic studies of petroleum supply development have shown that exploration is an ongoing effort to expand the potential for supply expansion. A backlog of developable prospects always exists. When profitable, the much more expensive development stage is undertaken.

It is difficult to give precise data at this time as the process is still in the development stage. In principle, in terms of heating, the process can be self-sufficient. However, depending on input quality of the MPW some...
