METHOD, SYSTEM AND TOOL FOR RESERVOIR EVALUATION AND WELL TESTING DURING DRILLING OPERATIONS |
摘要 |
A novel method, system and tool for performing formation and well evaluation while drilling are disclosed. These inventions determine the properties of a particular formation (F) within a reservoir as the reservoir is being intersected during well construction. In one form of the invention, the formation evaluation is made using a direct measurement of the formation's ability to flow fluids. The flow potential of a reservoir during underbalanc ed well construction is determined as the well is being constructed. The method s produce an understanding of the volumes and types of the fluids such as oil, gas, and/or water, that can be produced out of discrete sections of a formation within a reservoir as the reservoir is intersected. The trajectory and path of the wellbore through the reservoir are modified to intersect formation having more desirable permeability and productivity to decrease th e time to market of the hydrocarbon reserves within a reservoir without the ti me delay inherent when conventional formation evaluation techniques are applied . A downhole flow measurement instrument (27) is used to obtain actual flow ratios. The instrument is integrated into a near-bit stabilizer (12) and can be used for early kick and benign "breathing" fractures detection in the ope n hole wellbore.
