About this Training Course The drill string is the simplest piece of equipment in use on a drilling rig and at the same time, the most critical piece. We use the qualifier 'basic' because although 99% of the drill string comprises plain tubes that are just screwed together, the lowest section, just above the bit, can go to extreme loading and is fitted with highly sophisticated electronics packages providing both positional and lithological data as well as a steering system to drive and orient the bit. The principle tasks of the drill string are also deceptively simple. These are to: Convey each drill bit to the bottom of the hole and then to retrieve it when worn, Act as a conduit to convey drilling fluid at high pressure down to the bit and Transmit torque from surface to bit, occasionally in concert with a hydraulic motor to drive this bit. This 3 full-day course will cover in detail what it takes to decide on minimum drill string specifications, which are able to support the loads to which it will be subjected. In addition to the need to use a drill string with minimum strength requirements, we also need to ensure that we can prevent drill string failure. If the failure consists of a small split or leak of any kind, then the time involved may be little more than that required for a roundtrip to change the bit. If the string parts, then the recovery is likely to take a considerable amount of time. In a worst case scenario, the fish in the hole may prove impossible to retrieve, requiring a sidetrack. A less than optimal design of the string will reduce the efficiency of the operation and almost always leads to premature bit wear. This is particularly true when we are unable to measure and control the dynamics of the drill string as a whole and the bottomhole assembly in particular. Axial vibrations, torsional vibrations and lateral vibrations may take place in various degrees of severity. The behaviour of the drill string while operating under torsional vibrations is thought to be of great importance and may result in torsional buckling. This course will also cover the drilling optimization limiters, how to identify them and how to remove them. This is done by understanding the drill string dynamics - by operating under the most favourable conditions and by measuring the dynamics in the vicinity of the bit (or at the bit) in order to make timely adjustments. Training Objectives The course homes in what office staff needs to know and plan for and what field staff needs to know and implement. By the end of this course, participants will be familiar with: Critical dimensions of common drill pipe and weld-on tool joints and its relation to yield for calculation of tensile, torsional and burst resistance. Make-up torque of connections that relate to the tool joint dimensions and the torsional strength of that connection. Use of design factors and safety factors on tensile and torsional strength in relation to new and worn state. Conditions which could lead to drill pipe collapse. Situations where limitations on sinusoidal (snake) and helical buckling will apply and the influence of radial clearance and deviation. Failure of drill pipe (fatigue) and the circumstances under which these would occur (rotation across doglegs, pipe in compression etc). Mechanism under which hardbanding would induce casing wear and the methods applied to measure and prevent any significant wear. Drill pipe inspection methods we apply to identify early flaws/cracks/corrosion, to measure dimensions, to inspect tool joints etc. Common BHA components, including heavy wall drill pipe, their external/internal dimensions, connections (API, proprietary) and appearance (such as spiral). Significance of thread compounds to ensure the correct make-up torque is applied. Significance of drill string/BHA 'neutral point' in the context of drill string component failure. Basic design principles for a BHA make-up in a vertical, low/medium deviated and highly deviated well in terms of weight transfer and drag/torque. Stabilization principles for a pendulum (vertical), a stabilized (vertical or tangent), a build and a drop-off assembly. BHA design and stabilization in relation to mitigation/elimination of vibration and to the elimination of tension, torsion or fatigue failure. Matching bit aggressiveness, gauge length, BHA stabilization, steerability and Mechanical Specific Energy (MSE) to mitigate the severity of any vibration. Bit efficiency and reduction of wear by understanding mechanical and hydraulic limiters. How to perform a passive or active drill-off test. Importance of being conversant with API 7G RP and/or equivalent data books, to look up/check the recommended tensile/torque and other parameters for the drill string in use. Target Audience This course is intended for staff directly or indirectly involved in the delivery of challenging wells such as junior to senior well engineers, both in office-based planning and operations and field-based operator/contractor supervisory staff such as company men and toolpushers. Trainer Your expert course leader has over 45 years of experience in the Oil & Gas industry. During that time, he has worked exclusively in the well engineering domain. After being employed in 1974 by Shell, one of the major oil & gas producing operators, he worked as an apprentice on drilling rigs in the Netherlands. After a year, he was sent for his first international assignment to the Sultanate of Oman where he climbed up the career ladder from Assistant Driller, to Driller, to wellsite Petroleum Engineer and eventually on-site Drilling Supervisor, actively engaged in the drilling of development and exploration wells in almost every corner of this vast desert area. At that time, drilling techniques were fairly basic and safety was just a buzz word, but such a situation propels learning and the fruits of 'doing-the-basics' are still reaped today when standing in front of a class. After some seven years in the Middle East, a series of other international assignments followed in places like the United Kingdom, Indonesia, Turkey, Denmark, China, Malaysia, and Russia. Apart from on-site drilling supervisory jobs on various types of drilling rigs (such as helicopter rigs) and working environments (such as jungle and artic), he was also assigned to research, to projects and to the company's learning centre. In research, he was responsible for promoting directional drilling and surveying and advised on the first horizontal wells being drilled, in projects, he was responsible for a high pressure drilling campaign in Nigeria while in the learning centre, he looked after the development of new engineers joining the company after graduating from university. He was also involved in international well control certification and served as chairman for a period of three years. In the last years of his active career, he worked again in China as a staff development manager, a position he nurtured because he was able to pass on his knowledge to a vast number of new employees once again. After retiring in 2015, he has delivered well engineering related courses in Australia, Indonesia, Brunei, Malaysia, China, South Korea, Thailand, India, Dubai, Qatar, Kuwait, The Netherlands, and the United States. The training he provides includes well control to obtain certification in drilling and well intervention, extended reach drilling, high pressure-high temperature drilling, stuck pipe prevention and a number of other ad-hoc courses. He thoroughly enjoys training and is keen to continue taking classes as an instructor for some time to come.

Use Cases for Business Analysis: In-House Training The use case is a method for documenting the interactions between the user of a system and the system itself. Use cases have been in the software development lexicon for over twenty years, ever since it was introduced by Ivar Jacobson in the late 1980s. They were originally intended as aids to software design in object-oriented approaches. However, the method is now used throughout the Solution Development Life Cycle from elicitation through to specifying test cases, and is even applied to software development that is not object oriented. This course identifies how business analysts can apply use cases to the processes of defining the problem domain through elicitation, analyzing the problem, defining the solution, and confirming the validity and usability of the solution. What you will Learn You'll learn how to: Apply the use case method to define the problem domain and discover the conditions that need improvement in a business process Employ use cases in the analysis of requirements and information to create a solution to the business problem Translate use cases into requirements Getting Started Introductions Course structure Course goals and objectives Foundation Concepts Overview of use case modeling What is a use case model?

Regular expressions training course description Regular expressions are an extremely powerful tool for manipulating text and data. They are now standard features in a wide range of languages and popular tools, including Python and MySQL. Regular expressions allow you to code complex and subtle text processing that you never imagined could be automated. Once you've mastered regular expressions, they'll become an invaluable part of your toolkit. You will wonder how you ever got by without them. What will you learn Use Regular Expressions. Troubleshoot Regular Expressions. Compare RE features among different versions. Explain how the regular expression engine works. Optimize REs. Match what you want, not what you don't want. Regular expressions training course details Who will benefit: Anyone looking to use regular expressions. Prerequisites: None.
