Production Cumulative , Volumes

The most valuable source of price, production, and consumption statistics is Textile Organon 101, This periodical has published a valuable cumulative volume of textile statistics running through 1950. It also publishes an annual directory of man-made fiber producers, which describes fiber types from producers throughout the world and defines the trade-marks for synthetic fiber types. 

Up till now, petroleum policy was defined by two cartels - west and east. The first unites the six largest petroleum companies that extracts 40 percent of oil (by volume) from countries that are not OPEC members. The cumulative volume of sales for these companies in 1991 was almost 400 billion dollars. The eastern cartel (OPEC) includes thirteen countries, which makes up 38 percent of world oil production and 61 percent of world petroleum export. The oil production in Russia makes up 10% of world petroleum production. Therefore, it is possible to say with confidence that Russia occupies a strong position in the international petroleum market. For example, OPEC declared before the crisis that the member states of this organization could not fill any shortage of petroleum, should the world market lose Russia. 

Sakata et al.20 have also studied polyethylene degradation over a mesoporous silica catalyst. The material used, called KFS-16, is closely related to MCM-41, although it is prepared by a different method starting from a layered silicate (kanemite). One of the most interesting observations in this work is the PE cracking activity exhibited by KFS-16 in spite of the absence of acid sites (it is a completely silica-based material). Figure 5.10 shows the cumulative volume of liquid products obtained in the thermal and catalytic cracking of PE in a batch... 

Experience from many conventional oil and gas fields has shown that solids control should be installed before solids production occurs. It generally becomes more difficult to control further solids flow as the cumulative volume of produced solids increases. Consequently, in conventional oil and gas fields, initial solids control installations have proven to be consistently more successful than remedial treatments. Future enhancements will certainly improve the success of remedial treatments. The technology is continually advancing, and cost-effective through-tubing remedial methods are now available (55). 

If the EPA has not issued an LVE for a chemical substance that is being manufactured, but is not on the Inventory, the seller may be in violation of TSCA, and the buyer may be at risk for penalties and business disruptions if it continues manufactruing that product. Only one party to the transaction can rely on the LVE being available to it. The EPA may grant LVEs to multiple parties, but only if the cumulative volume is sufficiently low. 

A reasonable price within 1,500-2,000 for m of thin Pd based membranes and even less for Si or inorganic membranes could be reached at the end of next decade only if a cumulative volume of production high enough is reached. 

An industrially important quantity is the cumulative volume frequency Fy(dk). For example, it relates to the yield of suspension polymerization products as defined by product specifications. It is defined by... 

The experience curve is a phenomenon with its roots in the earlier notion of the learning curve . Researchers in the Second World War discovered that it was possible to identify and predict improvements in the rate of output of workers as they became more skilled in the processes and tasks on which they were working. Subsequent work by Boston Consulting Group, extended this concept by demonstrating that all costs, not just production costs, would decline at a given rate as volume increased (see Figure 1.3). In fact, to be precise, the relationship that the experience curve describes is between real unit costs and cumulative volume. 

Reservoir engineers describe the relationship between the volume of fluids produced, the compressibility of the fluids and the reservoir pressure using material balance techniques. This approach treats the reservoir system like a tank, filled with oil, water, gas, and reservoir rock in the appropriate volumes, but without regard to the distribution of the fluids (i.e. the detailed movement of fluids inside the system). Material balance uses the PVT properties of the fluids described in Section 5.2.6, and accounts for the variations of fluid properties with pressure. The technique is firstly useful in predicting how reservoir pressure will respond to production. Secondly, material balance can be used to reduce uncertainty in volumetries by measuring reservoir pressure and cumulative production during the producing phase of the field life. An example of the simplest material balance equation for an oil reservoir above the bubble point will be shown In the next section. 

Perhaps the biggest contribution that technological advancement in petroleum production will make is bringing large volumes of unconventional petroleum resources, eg, heavy oil and tar sands, into a viable economic realm by lowering the unit cost of production. Compared to the inventory of conventional petroleum reserves and undiscovered resources, the physical inventories of such unconventional petroleum resources are extremely large for example, the Athabasca tar sands in Alberta, Canada, are estimated to contain 360 x 10 m (2250 x 10 bbl) of in-place petroleum (19). This volume is equivalent to the total inventory, ie, the combined cumulative production, reserves, and undiscovered resources, of world conventional cmde petroleum. In... 

The estimated (DCFRR) and the estimated (NPV) are both functions of the estimated cumulative revenue from annual sales X As, the estimated cumulative total annual cost or expense X Ate, and the estimated fixed capital cost Cfc of the plant. The revenue from annual sales for each year is in turn the product of the sales price and sales volume. Initially it is desirable to select those values from the distribution cui ves of X As, X Ate, and Cfc which enable the maximum and minimum (DCFRR) and (NPV) to be calculated. 

At a sales price of 13.00 per barrel, the value of the incremental oil produced by the TFSA was between 94,900.00 and 117,000.00. This revenue was generated at a chemical cost of between 1.93 and 3.87 per incremental barrel. Cumulative incremental oil production, shown in Figure 5, indicates that the volume of incremental oil produced reached a constant and maximum value 18 months after the pilot was started. Of the total incremental oil recovered, 37.5 % was produced in the first six months of the pilot and 81.25 % was produced by the end of the... 

Resource estimates and current production The vast majority of the world s oil-sand deposits is located in Canada. Of the total in-place volume of around 1700 Gb of bitumen, only slightly less than 20% is assumed to be recoverable. The EUR of Canadian crude bitumen, i.e., reserves, resources and cumulative production as of the end of 2006, amounted to around 316 Gb. Taking the remaining reserves of around 174 Gb into account, Canada ranks second following Saudi Arabia in global oil reserves (see Table 3.3). However, the practice of including oil sands in official... 

A plot of boiling temperatures (°F) vs. cumulative percent volume removed from the sample is referred to as a distillation curve. The boiling temperatures for various products range from high to low divided into the following product types residue, heavy gas-oil, light gas-oil, kerosene, naphtha, gasoline, and butanes (Table 4.4). 

The ubiquitous occurrence, areal extent, and estimated volume of major LNAPL hydrocarbon pools beneath these facilities situated on the Los Angeles coastal plain are shown in Ligure 12.25. Lor purposes of this discussion, a pool is defined as an areally continuous accumulation of LNAPL. Two or more pools that have distinct differences in their respective physical and chemical properties are referred to as coalesced pools. Individual accumulations of relatively uniform product are referred to as subpools, since it is inferred that they have coalesced to form areally continuous occurrences. The occurrence of several pools and subpools at a particular site reflects releases from multiple sources at various times. The combined areal extent of these LNAPL pools is on the order of 1500 acres. The estimated cumulative minimum volume is on the order of approximately 1.5 million barrels an estimated cumulative maximum volume is on the order of 7.5 million barrels. The discrepancy in LNAPL hydrocarbon volume reflects varying methodologies involved in the estimates.
