摘要
(WO2019/219153) This invention proposes a method for estimating the level of a Free Water Level (FWL) and Water-Oil Contact (OWC) based on finding two intersecting trends of the pressure gradient (1) for oil (non-wetting phase) and (2) water (wetting phase) in the oil interval based on the results of drilling only one exploration well, penetrating only the oil- saturated part of the reservoir and not penetrating the water-saturated part of the reservoir and OWC. The pressure gradient trend (1) for oil (the non-wetting phase) is determined based on the results of the formation tester (MWD) and (2) for water (the wetting phase) in the oil interval from the capillary pressure curve, set for the tank height based on petrophysical data and special laboratory tests of core taken from the oil- saturated zone. The point of intercepting the pressure gradient trends (1) for oil (non- wetting phase) and (2) for water (wetting phase) indicates the FWL in the tank and the WOC position.

(WO2019/219153) Estimation of Free Water Level and Water-Oil Contact   Claim 1. A method to estimate FWL and WOC using data from only one exploration well that penetrated only the oil column of the reservoir and did not penetrate the water-saturated part of the reservoir and the WOC by:  • Interpreting well test (wireline formation   tester) and petrophysical data from core analysis (capillary pressure measurements) and log data  ( saturations ) .   * Determining pressure gradient trends (1) for oil (non-wetting phase) based on the results of wireline formation tester (MWD) and (2) for water (wetting phase) in the oil interval from the capillary pressure curve established for the reservoir height based on petrophysical data and special laboratory studies of the core sampled from the oil saturated zone.  Finding intercepting point of pressure   gradient trends (1) for oil (non-wetting phase) and (2) for water (wetting phase that indicates the FWL in the reservoir and position of the WOC.
