PanSystem 2 is a major development of the world's most successful well test analysis software. This release is more than an incremental improvement. It is a completely new program with a wide range of new benefits for well testing engineers. PanSystem 2 incorporates the highly successful Microsoft Windows TM graphical user interface and runs on PCs, networks and workstations. This new version combines in a single program all the functions needed to read in, edit and prepare data as well as perform analysis and simulation. The adoption of Windows allows easy data transfer between PanSystem 2 and other software programs such as presentation, word processing and spreadsheet packages. This will increase the productivity of petroleum engineers by reducing time spent on preparing reports. PanSystem 2 has been developed using the highest quality of design methodology ensuring that the product is robust and future-proof.
Data preparation has been greatly extended in PanSystem 2, allowing up to 100 data channels to be manipulated at the same time. In addition, the robust file-reading algorithm easily handles files with corrupt data and differing formats. Five different files, with 20 channels each, may be manipulated and plotted simultaneously. There is no limit to the number of points that can be handled; efficient data reduction can be carried out for the complete data set, or on graphically defined sections of data.
Analysis is performed on the complete sequence of test data by presenting the entire test to the user who can select the period for analysis by clicking on the 'ruler'. Analysis ranges from the basic industry-standard techniques on individual flow periods to advanced simulation of the complete data set. Multiple flow periods can also be selected. In this case, the data are plotted by rigorous superposition on the same graph and analysis is performed on all flow periods simultaneously. Any four plots can be selected and 'tiled' on the screen. Gas well testing is handled in an analogous way to oil using gas pseudo pressure but the conventional C&n and LIT analyses can also be performed. Horizontal and vertical wells are both handled b the software.
Simulation offers two principal options: Quick simulation, where the theoretical pressure response on any plot can be generated rapidly from the current reservoir parameters; and Advanced simulation, allowing the user to design a test and generate a time and pressure channel which is treated in the same way as raw data - it is analysed, overlaid and plotted to ensure that the test design will meet the engineer's requirements. Multiple layers and multiple offset wells can be defined so that the system acts as a full-scale, multi-layered, multi-well analytical reservoir simulator. Specialised type curves can be generated and saved from this section of software and used in analysing complex data sets.
Reporting includes standard and customised reports which include all data and computed results.

For petroleum engineers designing completions, forecasting performance, diagnosing well problems or optimising production from existing installations, version 3 of FloSystem brings a new level of sophistication, speed and accuracy. At the same time, the program remains simple to use ensuring rapid learning and a high level of productivity - an important factor in today's highly demanding oil and gas industry.
FloSystem 3 comprises two programs - WellFlo and FieldFlo. WellFlo allows the engineer to build well models either graphically or by using tabulated data. All important engineering parameters can be treated as sensitivity variables. This allows the engineer to model well performance to find, for example, the optimum gas injection rate in a gas lifted well, the optimum perforated interval or the benefit of operating an electrical submersible pump (ESP) at a higher frequency.
Once well models have been built and matched to measured data in WellFlo they can be combined into field models in FieldFlo. The operating conditions are optimised for the entire field including the network of surface flowlines. The petroleum engineer will find it easy to reconfigure a field system using the graphical user interface - wells can be moved from one separator train or pipeline to another by 'clicking and dragging' on the well icons. Many different scenarios can be reviewed to ensure optimum field production is achieved.
With this new modelling power, engineering studies which once took a week to perform can now be completed in a morning. Thus the benefit of FloSystem is derived from maximising hydrocarbon production by optimising the efficiency of engineering staff.
EPS CoreSystems is the UK's leading manufacturer of core analysis and coreflood systems technology. Since its inception in 1983, it has become a world leader with its reputation based on high-quality engineering and technical expertise. CoreSystems engineers are now recognised within the core analysis industry as providers of practical and innovative solutions to real and complex problems.
EPS has been offering high quality engineering training courses since the company's foundation in 1984, and we are continually updating the course contents to reflect our ongoing activity in petroleum engineering consultancy and software development. In 1995 EPS extended its open short course programme to include several international locations, and 1966 will see a further expansion in this activity, with a selection of courses scheduled to be held in North America, the Middle East and the Far East. Edinburgh Petroleum Services Ltd (EPS) holds regular introductory and advanced level courses in petroleum, reservoir and production engineering. The knowledge and experience of EPS tutors is highly regarded throughout the industry and they have been chosen for their teaching as well as their technical ability.
