OUTLINE

Wettability adalah kecenderungan fluida untuk menyebar membasahi permukaan batuan.

Wettability interaksi antara solid phase dengan fluids

DEFINITION OF WETTABILITY

• Reservoir rocks (sandstone, limestone, dolomite, etc.)

are the solid surfaces

• Oil, water, and/or gas are the fluids

IMBIBITION

Imbibition adalah proses aliran fluida dimana saturasi wetting phase semakin besar dan saturasi nonwetting semakin kecil. (contoh, waterflood pada reservoir yang bersifat water-wet).

Mobility of wetting phase increases as wetting phase saturation increases

◦ mobility is the fraction of total flow capacity for a particular phase

DRAINAGE

Proses aliran fluida dimana saturasi nonwetting phase increases

Mobilitas nonwettting fluids berbanding lurus dengan saturasi nonwetting fluids

Mobilitas yang cukup rendah Air cukup mudah diperoleh Pengadaan air cukup murah Berat kolom air dalam sumur turut

menekan, sehingga cukup banyak mengurangi besarnya tekanan injeksi yang perlu diberikan dipermukaaan

BENEFITS OF WATERFLOODING

PADA IMBIBITION, WETTING PHASE FLUIDS LEBIH BESAR

PADA IMBIBITION DIGUNAKAN METODE WATER FLOODING
