PE604PC: DRILLING FLUIDS LAB

B.Tech III Year II Semester (R16)

Prerequisites

Drilling Technology

Course Objectives:

  • To inform the students about the primary functions of drilling fluid
  • To introduce the test procedures for controlling the properties of drilling fluid
  • To introduce the common additives used to obtain the desirable properties under various drilling conditions
  • To explain main factors governing the selection of drilling fluids
  • To improve technical report writing skills

Course Outcome:

  • The students will be able to design desired drilling fluid.
  • They will be aware of weighing additives and viscofiers.
  • They can control filter loss.
  • They can maintain hydrostatic pressure to prevent the well and rig from getting damage.
