Course Details:  
   
Introduction: This course is designed for the Third Year students. The topics taught in the second year would be covered in depth during the year. Emphasis would be placed on bit selection, casing design and rig/long lead items selection procedure. Preparation of well budget and AFE (Approval for Expenditure) would also be covered in the course as it is a very essential segment of preparing a drilling campaign.
The course covers both the office and well site aspects of drilling. The students would be familiarize with engineering calculations which are commonly implemented at well site and these calculations would also be given as assignments.
Text Book: Drilling Engineering: Neal .J. Adams
Reference Book: Practical Well Planning and Drilling Manual: Steve Devereux
Course Grade: The Course Grade will be based on Quizzes (10 marks), Assignments/Presentations (10 marks). These will constitute Sessional marks (20marks) and 80% Final Examination .Students should be very particular about attendance and punctuality as casual attitude/indifference to these will have a negative effect on Sessional marks.
Course Duration: Theory: 60 Lecture Hours
Practical: 30 hours (in Classroom and Laboratory)
   

Theory
TOPICS
NO. OF PERIODS
OPTIMIZATION : optimization in drilling techniques with emphasis on directional drilling
4
FISHING: causes of fishing and its indication, types of pipe sticking and remedial procedures to release pipe, prevention of fishing: types of fishing tools
4
CORING: equipment: reasons for coring: procedures for collecting cores at well-sites and its description, packing of cores, drilling parameters for cutting cores. side wall coring: its procedure and requirement
4
DRILL STEM TESTING (DST): it’s requirement. Types of dsts.dst components and analysis of data. Precautions to be taken during dst.
4
CASING DESIGN: significance of safety factors. Types of connectors: selection of casing seats /depths. precautions to avoid casing burst/collapse and tensile break.
4
ORIGIN OF ABNORMAL PRESSURES: Drilling parameters for drilling a well in a high pressure zone. Precautions to avoid inflows. Methods to predict high pressure zones. Methods to kill or control a high pressured inflow.
4
DRILL BIT SELECTION: overview of structural approach: evaluating offset well drilling data: drilling hydraulics: using log data to aid in bit selection: types of bits: defining recommended bits: bha considerations related to bits; drilling program: bit selection and drilling parameters.
4
DRILLING FLUIDS: reaction of clays to water: general principles: dispersion and flocculation of clays n water: types of mud: dispersed water base mud: non dispered arwe base mud: formation damage with water based mud(and cements): oil mud additives: formation damage with oil mud: air, foam and aerated system: tendering for mud services
4
CASING RUNNING PROGRAM: normal drilling program requirements for running casing: addressing potential casing problems in the drilling program
4
CASING RUNNING PROGRAM: slurry properties: chemical washes and spacers: factors for ensuring a good cement job; cementing design for casings and liners: cementing cement plugs and squeezes: special purpose cementing (technique for balanced cement job)
4
FORMATION EVALUATION: electrical logging: coring: mud logging
4
DRILLING PROBLEMS: stuck pipe: lost circulation; washout detection procedure: backing off: fishing operations: using cement to stabilize the wellbore: making connect to minimize wellbore instability and losses: preplanned wiper tripping: barite plugs: diesel oil bentonite plugs (“gunk plug”)
4
DRILLING PROBLEMS-AVOIDANCE PLANNING:
Wellbore Stability: Stuck Pipe: Lost circulation
4
PREPARATION OF APPROVAL FOR EXPENDITURE

WRITING THE FINAL WELL REPORT  
     
Practical The practicals would focus on the concepts of the various drilling operations which are carried out at the drilling site. These consist of engineering concepts which will be explained in the classroom. The mud engineering practicals would be demonstrated/explained in the laboratory. Some pertinent exercises would be explained on the Drillsym 500 Simulator like procedure to control a high pressure influx and Drill Off Test. Revelent tasks on the Simulator is incorporated in the workbook.
Practical Workbook: Advance Drilling Engineering: PE-303  
Schedule of Practicals are given as follows
Lab Session No Title Venue
1 Abnormal Pressures Class Room
2 Kick or Influx Determination Class Room
3 IADC Dull Bit Grading Class Room and on availability of bit in the laboratory
4 Well Killing Methods/Procedures Class Room and use of Drillsym 500 Simulator
5 Drilling Equations Class Room
6 Determining Filtrate and Fluid Alkalinity(PF,MF,AND PM) Mud Engineering Laboratory
7 Determination of Total Hardness as Calcium Mud Engineering Laboratory
8 Determination of Low Temperature/Low Pressure Filtration Loss Mud Engineering Laboratory
Quizzes/Assignments/Presentations
  On completion of one topic of the course a quiz would be taken. Assignments would be given on any topic which has been taught and these assignments had to be completed within the specified time given by the teacher. Presentations are also a part of the teaching process and had to be presented from time to time. There is option of either individual presentation or as a “Group “The students should be mentally prepared for surprise quizzes. The above scope of tasks will constitute in giving Sessional marks so it is important that the students take this seriously and be particular about not missing classes and Punctuality.
Guidelines    
1.Prepare the notes after each lecture regularly.
2.Label the figures in a way to enlighten the quality and accuracy of concepts.
3.The assignments should be neat and the quality of paper and folder should be of acceptable standard.
4.Computer can be used for assignments rather preferable compared to writing with a pen but not mandatory.
