(IJCSIS) International Journal of Computer Science and Information Security, Vol. 9, No. 2, February 2011 An Information System for controlling the well trajectory Information Systems Safarini Osama IT Department University of Tabuk, Tabuk, KSA email@example.com firstname.lastname@example.org Abstract—: The well drilling process became very boring, A process of getting data on a spatial location of a bore-hole requires a choice of the justified solution from a set possible. includes two stages: obtaining of initial inclinometric Because of major bulk received and treated data, originating information with the help of various technical means and vastness of problem situations. The relevant value thus has processing of this information; and the role of processing is information supply of drilling process for a possibility of effective rather high. The main objective of processing is determination human-engine acceptance of a solution. The complexity of operations at boring inclined, horizontal, sectional, on shelf of of a location of a bore-hole, and by applying an appropriate ocean - all this requires adequate reacting at operating (on-Line) calculation method we can obtain more accurate results with control by well-studying process. The realization of computer- the same number of measurement points. Different Aided control systems in many aspects depends on progress the mathematical methods for plotting of a bore-hole path by the applicable computer for conducting conversation in an results of inclinometric measurements are available. However interactive system of automated control. the problems of processing are much wider. The problems of On-line control are closely connected with Keywords- Decision-Making, drilling process, inclinometric the problems of design of an optimal profile, and also with the data, automated control, Information System, well trajectory, problems of On-line management of slant hole drilling. In fact, azimuth and zenith angles, Plane Projection. control and management can be considered as two subsystems I. INTRODUCTION of a single system of control and management of a drilling The work describes methods and means for processing, process . presentation, interpretation of On-line inclinometric data of The methods and means described in this paper enable drilling. But it should be noted that the problems of resolution of the following problems of processing of inclinometric data processing are not directly provided with inclinometric information and design problems: methods of recognition . However, introduction of these - introduction of parameters of a design profile; problems follows, on the one hand, from a wish of a more - calculation of a design profile of a bore-hole; complete coverage of drilling problems and importance in - introduction, arrangement and merging of data base connection with a growing interest particularly to slant and obtained in multiple measurements; horizontal drilling.

For fulfilling of a project assignment for construction of a well, i.e., for drilling of a bore-hole along a design path with hitting the set point of penetration of a producing formation with minimum deviations the technologist should have a 7 http://sites.google.com/site/ijcsis/ ISSN 1947-5500 (IJCSIS) International Journal of Computer Science and Information Security, Vol. 9, No. 2, February 2011 possibility of continuous monitoring of a bore-hole path and revealing any deviations. Using such possibility a technologist can take timely management decisions and on their basis make necessary alterations in a controlled object  – a drilling process. The developed program in the Delphi environment makes it possible to show the actual and design bore-hole paths both projected on a vertical and horizontal plane and axonometrically (a spatial representation), to estimate parameters necessary for monitoring a bore-hole drilling, to collect, store and present information. A module for interpretation of inclinometric data “Fig. 1” consists of three modules: an initial data input module; a module for algorithmic calculations “Fig. 2”; an information output module “Fig. 3”. Figure 3 an Information Output Module (3D Well Trajectory Plane Projection) In the next future the work will be continued to develop an information system for processing geology-technological data . III. CONCLUSION In this paper the following results were obtained: Developed, on the basis of the available mathematical software for processing of inclinometric data, is a program for Figure 1 Graphic interpretation of inclinometric data showing on a display of axonometric paths (Trajectory) of a design and actual well, their turning around the vertical, selection of projections to horizontal and vertical planes, scaling of selected parts of paths, changes of azimuth and zenith angles, prediction of these changes in relation to an assumed zone of hitting the assigned area of a path.
