Dalam kegiatan eksplorasi minyak dan gas bumi sangat diperlukan
adanya ketelitian, kecermatan serta ketepatan dalam mengambil keputusan.
Hal-hal ini yang berpengaruh dalam menganalisis kehadiran elektrofasies,
mencari nilai petrofisika serta menentukan nilai reservoir pay yang ada di
suatu sumur.
Dari data logging yang ada dapat dilakukan penilaian formasi dengan
interpretasi pintas / quick look atau dengan menggunakan software. Penilaian
formasi bertujuan untuk menentukan bentukan elektrofacies, interpretasi
litologi, penentuan fasies dari karakter log, penentuan zona fluida, perhitungan
evaluasi formasi, permodelan fasies, penentuan porositas, permeabilitas,
saturasi air dan hasil akhir yang dicari adalah menentukan reservoir pay ada
ada di sumur PUT-1.
Hasil perhitungan dalam menentukan reservoir pay dari data yang ada
diketahui bahwa zona prospek berada di zona 3 dan 4 dengan hasil sebagai
berikut: Zona 3 didapatkan gross interval 56 m, net reservoir 27, net/gross
reservoir 0.482, average PHIE reservoir 0.288, average SW reservoir 0.175,
average Vcl reservoir 0.065, PHIE height reservoir 7.77, PHIE SO height
reservoir 6.41, Vcl height 1.74. Zona 4 didapatkan gross interval 53 m, net
reservoir 36.50, net/gross reservoir 0.689, average PHIE reservoir 0.288,
average SW reservoir 0.339, average Vcl reservoir 0.073, PHIE height
reservoir 10.5, PHIE SO height reservoir 6.94, Vcl height 2.66. Dari data
diatas menunjukan ketebalan reservoir pay pada zona 3 adalah 6.41 m
sedangkan ketebalan reservoir pay pada zona 4 sebesar 6.94 m.

In the oil and gas exploration activities is necessary precision,
accuracy and accuracy in making decisions. These things are influential in
analyzing the presence of electrophage, searching for petrophysical value and
determining the value of the reservoir pay in a well.
From the existing logging data can be done formation assessment with
shortcut interpretation / quick look or by using software. The formation
assessment aims to determine the formation of electrofacies, lithologic
interpretations, facies determination of log characters, fluid zone
determination, formation evaluation calculations, facies modeling, porosity
determination, permeability, water saturation and the desired end result is to
determine a reservoir of pay available at the PUT- 1.
The calculation results in determining the pay reservoir of the
available data is known that the prospect zone is located in zones 3 and 4 with
the following results: Zone 3 obtained gross interval 56 m, net reservoir 27,
net / gross reservoir 0.482, average PHIE reservoir 0.288, average SW
Reservoir 0.175, average Vcl reservoir 0.065, PHIE height reservoir 7.77,
PHIE SO height reservoir 6.41, Vcl height 1.74. Zone 4 obtained gross
interval 53 m, net reservoir 36.50, net / gross reservoir 0.689, average PHIE
reservoir 0.288, average SW reservoir 0.339, average Vc reservoir 0.073,
PHIE height reservoir 10.5, PHIE SO height reservoir 6.94, Vcl height 2.66.
From the data above shows the thickness of reservoir pay at zone 3 is 6.41 m
while the thickness of reservoir pay at zone 4 is 6,94 m.
