3 1.INTRODUTION

4 INTRODUTION 1.1 DRILLING IN OIL AND GAS 1ST UPSTREAM EDWIN DRAKE PENNSYLVANIA ONSHORE OFFSHORE

5 INTRODUTION 1.2 LIFE OF A PLANNING DRILLING COMPLETION PRODUCTION INTERVENTION ABANDONMENT WHERE TO DRILL? READY TO PRODUCE MAINTENANCE PRODUCE OIL AND GAS DRILL STOP PRODUCE OIL AND GAS

6 INTRODUTION 1.3 TYPE OF WILDCAT EXPLORATION APPRAISAL PRODUCTION INJECTOR ABANDONED Drilled outside of and not in the vicinity of known oil or gas fields Drilled purely for exploratory (information gathering) purposes in a new area Used to assess characteristics of a proven hydrocarbon accumulation Drilled for producing oil or gas Injected water or gas into the formation to maintain reservoir pressure Wells permanently plugged in the drilling phase for technical reasons. HORIZONTAL VERTICAL DIRECTIONAL MULTILATERAL
