Wellsite Geologists Study Rock Cuttings From Oil And Gas Wells To Determine What Rock Formations Are Being Drilled Into And How Drilling Should Proceed. They Identify Critical Strata From Core Samples And Rock-cutting Data And Build Up Knowledge Of The Structure Being Drilled.
They Are Experienced Geologists, Deciding When Specialised Tests Should Be Carried Out And, Ultimately, When To Stop Drilling. They Send Reports And Logs Of Completed Drilling To The Operations Geologist And Offer Geological Advice To Oil Company Representatives. They Also Incorporate Health And Safety Requirements In Daily Geological Operations.
Wellsite Geologists Also Liaise With Drilling Engineers, Petroleum Engineers And Mudloggers During The Course Of Projects.
