Based on field practice and analysis, it is found that weighted mud displacement has the following disadvantages: A Generally, weighted mud has a larger viscosity, which is not profitable to increase the pump speed and improve the displacement efficiency; B It takes a lot of labor power and material resources for the preparation of weighted mud, resulting in the increase of workload and loss of materials; C The weighted mud remained in the wellbore may affect the well logging in the later stage.

Bezier Curve Modeled Phase Diagram Hong Bao Department of Computer Science and technology, School of Computer and Communication Engineering, University of Science and Technology Beijing 100083 Beijing, China baohong@ies.ustb.edu.cn Keywords: phase diagram storage, data structure, Bezier curve modeling Abstract.
The method mainly tests the change of material’s property with continuous temperature change.
Commonly used methods are: step-by-step cooling curve method, differential thermal analysis, thermal expansion method, conductivity method, hot quality standard and X-ray diffraction method, etc. 2) Statistic method: usually, the relationship between material properties and temperature is measured with temperature preservation.
The experiments needed are mostly based on manmade material mixture.
Therefore, the activity coefficients become a key factor in the process of phase diagram calculation.

It might be very common factors such as machine failure, resource breakdown, material and labour shortage as always issued in manufacturing industry.
While, [7] has identified 5 types of uncertainty as follow; · Technical risk – scope change, technology selection, implementation technology selection, equipment risk, material risk and engineering/design change
This uncertainty model should constructive with decision-making support by communicating the uncertainty using science engineering/project management interface.
The factors were generated through conversations, discussions and observations along with the project contractors and construction engineer.

Manufacturing can be defined as the process of converting materials from one form to the form that customer’s desire.
A manufacturing system is an integration of machines, materials, humans, material handling devices and computers.
Each year, billions of dollars are spent on maintaining engineering equipment all over the world, and for manufacturing and process industry, service suppliers, maintenance practice is market driven.
To ensure the availability of installed production facilities for efficient use, there is need to have effective maintenance engineering systems (Damilare and Olasunkanmi, [6]).
