This paper presents an advanced concept in drilling optimization—the dynamic drilling strategy. The dynamic drilling strategy is a new methodology of drilling process planning and control; it combines theory of single-bit control with an optimal multi-bit drilling program for a well. In the simulation study, the dynamic drilling strategy was compared to conventional drilling optimization and typical field practices; the considerable cost-saving potential of 25 and 60 percent, respectively, was estimated. The method also appeared to be the most cost-effective for expensive and long-lasting PDC bits through better utilization of their performance and reduction in the number of bits needed for the hole.

The key to successful and cost-effective activities of enterprises is the rational organization of the planning process, which concerns financial indicators and involves writing budgets. The article summarizes the theoretical and practical aspects of the organization and implementation of budgeting in industrial enterprises. The study of approaches of different scholars to the interpretation of the essence of the concept of budgeting allowed defining it as a complex economic process of the management cycle. It is developed at the discretion of the enterprise by determining the amount and composition of the costs of individual units of the entity and ensuring coverage of these costs by the resources of the enterprise to achieve the ultimate goal of the entity – to obtain maximum profit at minimum cost, taking into account both internal and external factors. The role of budgeting for industrial enterprises, its main purpose, the list of entities involved in budgeting, as well as the fundamental criteria for budgeting were clarified. Based on the generalization of a number of the most important criteria for the company, the possible types of budgets as well as their advantages and specifics of use depending on the objectives of the entity were generalized and described. The analysis of the basic stages of budgeting which are carried out in the course of activity of the is enterprise carried out, terms of writing and representation of budgets on an example of the monthly, quarterly and annual financial period are considered. It is determined that the budgeting system is a tool of internal financial planning and control, which significantly increases the efficiency of financial management of the enterprise, preventing the irrational use of financial resources both at the planning stage and at the stage of control over their use. Given the lack of established norms and rules for budgeting in the enterprise, optimizing the organization of the budgeting process and the effectiveness of financial planning are the tasks of the internal system of corporate governance.

With narrow Density Windows wells and high pressure oil and gas well drilling growing in number, the kick risks becoming increasingly prominent and higher requirements for well control technology being needed, the manage pressure drilling (MPD) technology is used more and more widely. The problems like how to effectively find gas overflowand how to effectively control the overflow in the MPD must be solved.Well must be shuted timely in conventional drilling when overflow happens.The special characteristics of overflow control equipment determines the diversity and effectiveness of its overflow monitoring means in MPD, and the overflow is found more effectively and timely than conventional drilling. Well control risk will increase sharply if kick cannot be timely and effectively identified and controled when overflow occurs. MPD can quickly adjust the wellhead back pressure and inhibit the formation fluid further invasion. Therefore, combining with MPD process and the fluid pressure parameters, the article establishs process of kick recognition and kick control, analyses of the process and analyzes and evaluates the pressure response in process of kick control.MPD can better control the bottom hole pressure in well control situation, ensuring drilling safety. The process of kick recognition and control is of great significance to promote the development and application of kick control technology in MPD.

Effluent Charges

Abstract In their seminal 1971 paper, W. J. Baumol and W. E. Oates analyzed effluent charges and ‘command and control’ regarding their ability to attain a given standard of environmental quality at minimum cost. In the subsequent literature, transferable discharge permits (TDPs) have been added to the portfolio of standard oriented environmental policy instruments. We place these instruments in a dynamic context. Here, cost minimization is defined in an intertemporal setting allowing for induced technical change. It turns out that the relative performance of alternative policy instruments regarding their ‘dynamic cost-effectiveness’ crucially depends on the information available to the involved agents. Under adverse informational conditions, only a TDP system with future markets is dynamically cost-effective.

Effective Planning

Situations have frequently been encountered where It Is necessary to reestablish control of a shipbuilding contract when it has been lost. This has to be done quickly, and requires a combination of an effective planning and control system with a computer for data processing. Expediency dictates the use of readily available PCs and proprietary software. The approach adopted was found to be robust and effective, and has been used as a basis for development of more formal planning and control systems. These are now in use as the means of planning and implementing ship production.

The growth in horticultural and some industrial development in selected areas of Northland has led to a need for more specific and careful planning and control of limited resources in a number of major catchments. The potential irrigation demands for horhculture comprise over 60% of Northland's potential water requirements. By contrast, farm water supply needs are only 11% of these needs. Because of their importance to the Northland economy, and in the legislation these needs are given a high priority in water resource management planning. Land uses, including pastoral farming, require careful operation to reduce diffuse sources of pollution.

The principal objective of this research is to create a system that is quickly deployable, scalable, adaptable, and intelligent and provides cost-effective surveillance, both locally and globally. The intelligent surveillance system should be capable of rapid implementation to track (monitor) sensitive materials, i.e., radioactive or weapons stockpiles and person(s) within rooms, buildings, and/or areas in order to predict potential incidents proactively (versus reactively) through intelligence, locally and globally. The system will incorporate a combination of electronic systems that include commercial and modifiable off-the-shelf microcomputers to create a microcomputer cluster which acts as a mini supercomputer which leverages real-time data feed if a potential threat is present. Through programming, software, and intelligence (artificial intelligence, machine learning, and neural networks), the system should be capable of monitoring, tracking, and warning (communicating) the system observer operations (command and control) within a few minutes when sensitive materials are at potential risk for loss. The potential customer is government agencies looking to control sensitive materials and/or items in developing world markets intelligently, economically, and quickly.
