Incremental project

The production profile for oil or gas is the only source ofrevenueior most projects, and making a production forecast is of key importance for the economic analysis of a proposal (e.g. field development plan, incremental project). Typical shapes of production profile for the main drive mechanisms were discussed in Section 8.2, but this section will provide some guidelines on how to derive the rate of build-up, the magnitude and duration of the plateau, the rate of decline, and the abandonment rate. 

Artificial lift techniques are discussed in Section 9.6. During production, the operating conditions of any artificial lift technique will be optimised with the objective of maximising production. For example, the optimum gas-liquid ratio will be applied for gas lifting, possibly using computer assisted operations (CAO) as discussed in Section 11.2. Artificial lift may not be installed from the beginning of a development, but at the point where the natural drive energy of the reservoir has reduced. The implementation of artificial lift will be justified, like any other incremental project, on the basis of a positive net present value (see Section 13.4). 

This means that the incremental net present value for the pollution prevention improvement, INPV, can be calculated from the incremental project cost the additional capital investment needed for pollution prevention technology, PC, and the yearly savings resulting from the pollution prevention improvement, YS. The question is how to estimate YS. 

The role that a host facility plays in an incremental development project can vary tremendously. At one extreme all production and processing support may be provided by the host (such as gas lift and water treatment). On the other hand, the host may just become a means of accessing an export pipeline (if a production and processing facility is installed on the new field). 

Whatever form of incremental development is considered, the benefits to the host facility should not be gained at the expense of reduced returns for the new project. Incremental and satellite projects can in many situations help to extend the production life of an old field or facilities, but care must be taken to ensure that the economics are transparent. 

The cheat/server model oftea allows easier iategratioa with other aetwork apphcatioas (eg, fiaance, project management, or human resources) which typically operate ia the environment of the server component of the cheat/server system. Gheat/server can be gradually iatroduced ia an existing minicomputer environment, often with httie adverse incremental impact ia terms of retraining and additional cost. 

Most CO2 miscible EOR projects are located in the west Texas Permian Basin where as much as two-thirds of the oil remains after waterflooding. An incremental (10%) recovery is typical for Permian Basin CO2 floods, which could correspond to as much as 0.5 x 10 (3-4 x 10 bbl) (23). 

Self-baked carbon electrodes are those whose shapes are formed in situ (33). The carbonaceous mixture is placed into a hoUow tube-shaped metal casing. The upper end receives the unbaked mixture as a soHd block, small particles, or warm plastic paste. The casing contains inwardly-projecting longitudinal perforated fins that become surrounded by baked carbon as the casing is incrementally moved downward and through the contact plates. Casing and carbon are consumed in this furnace. 

Incremental Comparisons A company may have the choice of, say, investing 10,000 in project J, which will give a (DCFRR) of 16 percent, or 7000 in project K, which will give a (DCFRR) of 18 percent. Should it spend 10,000 on project J or spend only 7000 on projec t K and invest the difference of 3000 elsewhere ...

In the first case, the minimum values for the economic yardsticks were evaluated assuming that a conservative 7300 bbl (= 8150 bbl -850 bbl 1160 m3 = 1295 m3 - 135 m3) of incremental oil had been produced by the end of the project. Maximum values for the economic data were calculated by assuming that 9000 bbl (= 8150 bbl + 850 bbl 1430 m3 = 1295 m3 + 135 m3) of incremental oil were produced by only 61.6 % of the TFSA which had been injected into Well TU-120 this assumption is based on the results of the tracer study which showed that as much as 38.4 % of the injected fluids flowed out of the pilot pattern. In the final case, the most probable values for the economic yardsticks were calculated assuming the 8150 bbl (1295 m3> of incremental oil were produced by 90 % of the TFSA. 

Analysis of the hyperbolic decline curves indicated that 8150 + 850 bbl (1295 + 135 m3) of incremental 18° API oil were recovered during the 18 month pilot project. 

Budget = 500 -> F + K + B. This case shows that the rale does not always mean choosing the project with the lowest incremental cost-benefit ratio out of the mutually exclusive projects. If we have a budget of 500 we should in theory choose A + F + K, but then there would be 100 left over. With the extra 100 we can implement B instead of A, since it produces more benefits. 

Expected changes are less dramatic in the HIRHAM H model, which projects a reduction of 3.8% for the mean annual precipitation and an increase of 4.2°C for the mean annual temperature. While the two RCMs predict quite different reductions of the mean annual precipitation, with HIRAM H showing only a slight reduction, both models agree in a dramatic increment of the annual temperature for the time-slice 2071-2100, with RCAO E projecting the largest increase with respect to the control period. 

The right column of Fig. 14 shows the projected changes for the summer (JJA) streamflows. Subcatchment 079, located in the northern part of the basin and with the largest elevation range, shows a decrease in low flows accompanied by an increase in the medium and high flows, with the largest increments predicted by the... 

Section 13.5 introduces a set of process patterns that are elaborated on throughout the case study. These patterns describe some of the broad contexts for development and a reasonable strategy for each one. Pattern 13.1, Object Development from Scratch, outlines an approach for developing a system from scratch. Pattern 13.2, Reengineering, addresses the case when an existing design is being reworked. Pattern 13.3, Short-Cycle Development, motivates development in short incremental cycles as a useful basis for many projects. 

Iterations and increments must have clear objectives or else they can become a euphemism for structured hacking. Increments should be planned at multiple levels, from end-user increments to those that are internal to the development team or visible and demonstrated up to the project manager. Packages and their import relations are used to plan iterations and increments.

We may consider all the operations of a start-up company, or the incremental operations of a project attached to an existing company. Let us consider the example in table 11.6.
