Course Objective:

The main objectives of the course are:

  1. To provide a wide knowledge and understanding about how drilling, production, processing, transportation and well intervention are performed in subsea environment.
  2. To impart the necessary knowledge about special cases and tools like coiled tubing, solid expandables, HPHT wells, multilateral wells and Intelligent wells.
  3. To make the students understand the importance of Material selection for subsea operations and to impart knowledge about making cost effective material selection

Student Handouts:

More than 170 pages of handout notes will be provided to the participants during the class. The e-version of these handouts will also be available on the INFONIX for the participant to access, for up to 90 days from the start of the course.

Tutor Information:

Mr. Vipin Bhalla, Drilling Manager (Rtd), has over 30 years of hands-on experience in Drilling & completion. He has held various positions at all levels in his extensive career from Driller to Drilling Manager. He has worked on Rigs across India and also has more than 5 years experience as Drilling Supervisor in Kuwait, Abu Dhabi & Oman. During his experience which spreads across 4 decades, he has vast experience in tackling well kicks, total Mud loss scenarios, drilling high pressure gas wells, drilling wells with horizontal drain holes, executing well killing operations, drilling wells up to 4,800mts deep, drilling highly deviated, horizontal and extended reach wells, drilling HPHT wells, drilled wells with high degree of cavings and differential sticking problems, Performed Fishing operations, to name a few of the feathers in his cap. He has vast practical knowledge in drilling, completion, well intervention, drilling re-entry wells, MWD systems and HSEQ management at rigs. He has also got a few years of experience in co-coordinating Rig construction & Rig refurbishment operations.

Mr. S.B. Srivastava, General manger of Construction & Maintenance (Rtd) department of ONGC, has over 32 years of field experience with process facilities. He has extensive experience in execution and handling of LSTK / EPIC contracts for various pipelines, Process facilities, eg.GGS, GCS, Crude Oil Tanks Farm, Effluent treatment Plant construction at Offshore as well as Onshore Assets. Over the years he has held several positions within ONGC, which includes being Project Head for construction of 6 offshore well platforms and Project Manager for construction of 5 other offshore well platforms. He has also held the position of ‘Head of Pipeline & Civil Works’ and carried out construction of Trunk & Flow pipelines and drill site civil construction work. He has also worked as ‘Group Head & Design Manager’ for various offshore well platform & subsea pipeline projects. He has also got more than 12 years of hands on experience in various pipeline laying projects, both offshore & onshore. He was involved in the first ever offshore underwater pipe laying project in India in the year 1985, and laid a 36” dia pipeline from an offshore platform to onshore terminal.

Method of delivery:

The instruction is conducted in a classroom provided with spacious & friendly environment for the students. Each individual will have separate seating arrangement, with enough space providing comfort. Projector & board will be used to show slides and to explain concepts. Beside this, reading room & desktops with internet facility is available for every individual student to further enrich their knowledge outside class hours. KIER has developed an online self assessment portal called INFONIX were every participant can log into their account (username & password will be provided by the institute) were they can take self assessment for the course they have enrolled for and also can read the electronic version of each module. The user account will stay active for 3 months from the date of joining.
