Drilling Engineering (Free PDF)


File Size: 8.32 Mb

Description
Before drilling an exploration well an oil company will have to obtain a production licence. Prior to applying for a production licence however the exploration geologists will conduct a ‘scouting’ exercise in which they will analyse any seismic data they have acquired, analyse the regional geology of the area and fi nally take into account any available information on nearby producing fi elds or well tests performed in the vicinity of the prospect they are considering. The explorationists in the company will also consider the exploration and development costs, the oil price and tax regimes in order to establish whether, if a discovery were made, it would be worth developing.

If the prospect is considered worth exploring further the company will try to acquire a production licence and continue exploring the fi eld. This licence will allow the company to drill exploration wells in the area of interest. It will in fact commit the company to drill one or more wells in the area. The licence may be acquired by an oil company directly from the government, during the licence rounds are announced, or at any other time by farming-into an existing licence. A farm-in involves the company taking over all or part of a licence either: by paying a sum of money to the licencee; by drilling the committed wells on behalf of the licencee, at its own expense; or by acquiring the company who owns the licence.
