Designing the well Translating the geological prognosis into a well design Rig selection Types of drilling rigs – onshore and offshore Drilling equipment The rotary system – conventional, top drive, rotary steerable Automated rigs Contractor selection Casing and Cementing Drilling muds and completion fluids; types and functions Bits and specialised drilling equipment Formation and well evaluation requirements: Mud logging Wireline and MWD/LWD logging Case Study: Casing design including uncertainties in
pressure and rock strength Case Study: Identification of potential drilling hazards

Drilling the wellMonitoring progress in drilling operations The daily drilling report – what does it contain
and how do you read it? Well control issues – why the drilling foreman
needs a certificate: Mud control and testing Casing and cementing operations Things that can go wrong Stuck pipeOverpressuresLost circulationKicks

Completing the wellTypes of completions – what is their
function? Completion fluids – why are they
different from drilling fluids? Basic completion string equipment
and Xmas trees Sand control equipment – from
screens to gravel packs Perforation technology – equipment
and safety aspects
