1. Ho Fumana Boitsebiso ba Nako ea 'Nete
LWD: E fana ka phumano ea nako ea 'nete ea data ea tlhahlobo ea sebopeho, ho kenyelletsa le resistivity, mahlaseli a gamma, le porosity. Sena se thusa litsebi tsa thuto ea mahlale le lienjineri ho lekola thepa ea polokelo ha ho cheka ho ntse ho tsoela pele.
MWD: E fana ka tlhokomelo ea hang-hang ea litekanyo tsa ho cheka tse kang trajectory, boima ba bit, le torque. Lintlha tsena li bohlokoa bakeng sa ho ntlafatsa ts'ebetso ea ho cheka le ho netefatsa botsitso ba seliba.
2. Kutloisiso e Ntlafetseng ea Letamo
LWD: E thusa ho tsebahatsa lintlha tsa polokelo ka ho tsoela pele ho lekanya thepa ea sebopeho. Sena se fana ka kutloisiso e ntle ea lithology, litaba tsa mokelikeli, le litšobotsi tsa pore.
MWD: E kenya letsoho kutloisisong ea polokelo ka ho fana ka leseli mabapi le likhatello tsa sebopeho, thepa ea mokelikeli le liparamente tsa geomechanical. Tlhahisoleseding ena e thusa ho rera hantle le ho etsa liqeto tsa tsamaiso ea polokelo
3. Geosteering le Wellbore Placement
LWD: E nolofalletsa geosteering e nepahetseng ka ho fana ka lintlha tsa nako ea sebele mabapi le meeli ea sebopeho le libaka tse nang le hydrocarbon. Sena se tiisa hore ho beoa seliba se nepahetseng hantle bakeng sa ho kopana le letamo.
MWD: E thusa ho geosteering ka ho beha leihlo maemo a ho cheka le ho fana ka maikutlo mabapi le litselana tsa seliba. Basebelisi ba ka fetola tataiso ea ho cheka ka nako ea 'nete hore ba tsamaee ka har'a mekhoa e rarahaneng le ho qoba likotsi.
4. Tšebeliso e Ntle ea ho Epa le Ho Boloka Litšenyehelo
LWD: E ntlafatsa bokhoni ba ho cheka ka ho hloaea libaka tse ntle tsa ho cheka le ho etsa hore seliba se behoe hantle. Sena se fokotsa nako ea ho cheka, se fokotsa litšenyehelo tsa ts'ebetso, 'me se eketsa matla a moruo a liliba.
MWD: E ntlafatsa bokhoni ba ho cheka ka ho ntlafatsa maemo a ho cheka le ho fokotsa nako e sa hlahiseng litholoana. Tlhokomelo ea nako ea sebele e lumella hore ho be le liphetoho hang-hang mesebetsing ea ho cheka, e lebisang ho boloka litšenyehelo le ho eketseha ha tlhahiso ea ho cheka.
5. Phokotso ea Kotsi le Tšireletseho
LWD: E thusa ho fokotsa likotsi tsa ho cheka ka ho fana ka tlhahlobo ea pele ea liphetoho tsa sebopeho, phallo ea metsi le likotsi tsa ho cheka. Sena se lumella basebelisi ho kenya ts'ebetsong mehato ea thibelo le ho boloka botšepehi ba hantle.
MWD: E kenya letsoho polokehong ka ho beha leihlo maemo a ho cheka le ho lemosa basebetsi ka likotsi tse ka bang teng ka nako ea nnete. Mokhoa ona oa ho sebetsa ka potlako o fokotsa menyetla ea likotsi hape o netefatsa polokeho ea basebetsi le lisebelisoa.
6. Ho eketsa Pholiso ea Hydrocarbon
LWD: E bapala karolo ea bohlokoa ho holiseng ho hlaphoheloa ha hydrocarbon ka ho hloaea nako ea polokelo e hlahisang litholoana le ho ntlafatsa maano a ho phethela. Sena se lebisa ts'ebetsong e ntlafetseng le ho eketsa chai ea tlhahiso.
MWD: E tsamaisa liqeto tse nepahetseng tsa ho beoa ha seliba le taolo ea polokelo ea polokelo, qetellong ea eketsa ho hlaphoheloa ha hydrocarbon le ho lelefatsa bophelo ba moruo ba libaka tsa oli le khase.
