METHOD AND APPARATUS FOR DETERMINING FORMATION WATER SATURATION DURING DRILLING. |
摘要 |
<p>A method for determining water saturation in a subsurface formation include determining an invasion depth in the formation from a plurality of measurements made within a wellbore drilled through the formation. The measurements have different lateral depths of investigation into the formation. Carbon and oxygen in the formation are measured at substantially a same longitudinal position as at a position of the determining the invasion depth. The measured carbon and oxygen and the invasion depth are used to determine the water saturation in a substantially uninvaded part of the formation.</p> |
