Abstract

Alteration of wettability to more water-wet and thereby improvement of spontaneous imbibition of water<br>during sea water injection, has been studied using reservoir core plugs from two fractured chalk fields.<br>Core plugs were prepared by removing easily accessible sulphate. The wettability conditions were<br>characterized using the sulphate wettability test. Spontaneous imbibition of water was studied using brines<br>with different ratios between formation water and sea water. The wettability and spontaneous imbibition<br>for reservoir core plugs and outcrop core plugs were compared.
