    Oil Well Drilling Problems

        like any process in the oil industry, oil well drilling has its own problems,  and each problem has its own causes and remedy, you have to well-understand the drilling process to deal with drilling problems. we can summarize the drilling problems as follows: Oil Well Drilling Problems : – Stuck pipe – Lost circulation – Borehole instabilities – Mobile formation – Undergauge hole – Kicks and blowout (1). Stuck Pipe/Pipe Sticking: it is one of the most common problems in oil well drilling process. Definition: When part of the drill pipe or collars are stuck in the hole If pipe cannot be rotated or pulled and circulation is…

    Oil Well Cementing Functions, Classes and Equipment

        Functions of cement –  Restriction of fluid movement between permeable zones –  Provision of mechanical support of the casing string –  Protection of casing from corrosion –  Support of the well-bore walls to prevent collapse of formations The manufacture and composition of cement –  Raw material from calcareous and argillaceous rocks (limestone, clay, shale and slag). –  Dry raw materials finely ground and mixed in correction proportions (kiln feed). – Chemical compositions of dry mix determined and adjusted. – Kiln feed fed at a uniform rate in a sloping rotary kiln. – The mixture travels at the lower end. – Powdered coal, fuel oil or gas, fired into the kiln.…

    Well Logs

    by Ahmed Imad   Well log is a continuous record of measurement made in bore hole respond to variation in some physical properties of rocks through which the bore hole is drilled. Traditionally Logs are display on girded papers shown in figure1. Now a days the log may be taken as films, images, and in digital format.   HISTORY   1912 Conrad Schlumberger give the idea of using electrical measurements to map subsurface rock bodies.    in 1919 Conrad Schlumberger and his brother Marcel begin work on well logs.    The first electrical resistivity well log was taken in France, in 1927.    The instrument which was used for this purpose…

    Completion Techniques

        by Abass Radhi Abbas 1.General Communication between the formation and the wellbore will directly affect the productivity of the well. Factors such as hydrocarbon saturation, porosity, permeability, fluid properties and geometry can be measured or inferred from the measurements but they cannot usually be controlled. By contrast, completion can be controlled and thus affect well performance. During the drilling, logging and testing phase of the well, valuable information will have been gained and the relevant completion technique chosen. There are two main categories of completions to consider with, of course, many variations; –  Open hole Completions. – Cased Hole Completions. 1.1.Openhole Completions An open hole completion is when…
