Course Introduction

• The wireline logging and perforations course covers a wide range of wireline logging operations . measurement  while drilling  and perforations.
• The first two  days  cover  the open hole  logging(PEX. LDL.CNL,GR, CALPER .SP.PI). and measurement while drilling (MWD and LWD) and the modern open hole logging (analysis  behind casing ABC)
• The remaining three days   cover cased hole logging (PLT. PSP.TDT  RST.CBL/VDL. GR/CCL) and perforations tubing punch and running  PKR and plugs
