Abstract The ability to identify underperforming wells and recover the remaining oil in place is a cornerstone for effective reservoir management and field development strategies. As advancement in computing programming capabilities continuous to grow, Python has become an attractive method to build complicated statistical models that predicts, diagnose or analyze well performance, efficiently and accurately. The aim of this study is to develop a computational model that will allows us to diagnose and analyze well performance using nodal analysis with the help of python. In this study, python was used to compute Nodal analysis method using Darcy and Vogel Equations. A case study was carried out using the data obtained from a field operating in the Niger Delta. Again, sensitivity of tubing size was conducted using python. The results obtained showed that a computational model with python has the ability to visualize, model and analyze wells performances. This technique will petroleum engineers to better monitor evaluate and enhance their production operation without the need for expensive softwares. This will reduce operating cost increases revenue.

In MEMS nodal analysis method, more available libraries of nodal models are needed. By analyzing the mathematic model and the equivalent model of the electro-thermal-mechanical beam, this paper shows the steps of building a library of a nodal element for HSPICE. Then the cell library is used to simulate the opposite type micro-array thermal actuator (MATA). At last it shows the DC sweep performance and the transient performance of opposite type MATA. In this paper, to verify the reusability of the beam cell, opposite type MATA is all consisted of the electro-thermal-mechanical beam cell in library.

Nodal analysis, defined as a systems approach to the optimization of oil and gas wells, is used to evaluate thoroughly a complete producing system. For the systematicness easily ignored during the design of artificial lifting system, based on coordination principle of reservoir, wellbore and lifting equipment, the concept of well performance curves are proposed. With the well performance curves, a new nodal analysis method of artificial lifting system is obtained, which is more efficient. Upstream and downstream pressure of pump and pressure difference provided by pump are displayed in well performance curve, which reflects the property of the well itself. Through further research of well performance curve, the energy of well itself will be fully developed, system effectiveness will be raised, and energy consumption will be reduced.

Testing Data

A nodal analysis method for thermodynamic analysis of Stirling engine is modified based on the check of mechanical loss and the temperature of the heater and cooler. A computational modeling for simulating the process of oscillating flow and heat transfer occurring in the P-40 four-cylinder double-acting Stirling engine has been developed, and the changing effects of different parameters such as the internal pressure, temperature, velocity, power and efficiency are obtained. Numerical simulation results show that they coincide with the testing data given by NASA. The influence of speed, working fluid and average pressure on the engine output performance is analyzed by the modified nodal analysis method. This method is a useful tool for the optimal design and operating characteristic analysis of Stirling engine.
