摘要： A methodology for reservoir understanding that performs investigation of asphaltene instability as a function of location in a reservoir of interest. In the preferred embodiment, results derived as part of the investigation of asphaltene instability are used as a workflow decision point for selectively performing additional analysis of reservoir fluids. The additional analysis of reservoir fluids can verify the presence of asphaltene flocculation onset conditions and/or determine the presence and location of phase-separated bitumen in the reservoir of interest.

摘要： The invention provides a method for determining phase transition pressure of downhole retrograde condensate. An OBM-contamination value is produced from a time-series of fluorescence values produced by measuring fluorescence emitted from a single-phase flow of OBM-contaminated formation fluid in a downhole cell during a cycle of time. The pressure of fluid in the cell is set at a transition boundary by incrementing drawdown pressure and monitoring the presence or absence of a phase transition. An apparent phase transition pressure value associated with the cycle of time is produced by setting apparent phase transition pressure value equal to cell pressure. This process is repeated for several cycles of time to produce a number of pairs of OBM-contamination value and apparent phase transition pressure value as OBM-contamination decreases over time. The value of phase transition pressure is determined by extrapolating from a representation of apparent phase transition pressure values versus OBM-contamination values.
摘要翻译：本发明提供一种确定井下逆行冷凝物相变压力的方法。 OBM污染值是通过在一段时间内通过测量从井下孔中的OBM污染的地层流体的单相流发射的荧光产生的荧光值的时间序列产生的。通过增加压降压力并监测相变的存在或不存在，将电池中的流体压力设定在过渡边界。通过将表观相变压力值设置为等于电池压力来产生与时间周期相关的表观相变压力值。该过程重复几个周期，以产生多个OBM污染值和表观相变压力值对，因为OBM污染随时间而减少。通过从表观相变压力值与OBM污染值的表示进行外推来确定相变压力的值。

The apparatus comprises a downhole tool including a flowline for flowing the formation fluids capable of isolating a quantity of the formation fluids in a portion thereof; and a pump unit for depressurizing the isolated formation fluids; and a measurement controller which controls the downhole tool. The measurement controller includes a rough value estimation unit which estimates a rough value of the bubble point pressure of the formation fluids; and a speed controller which controls the depressurizing speed of the pump unit such that the isolated formation fluids are depressurized at a first speed to a certain pressure which is a predetermined value higher than said estimated rough value, and the isolated fluids are depressurized at a second speed which is slower than said first speed in order to measure a precise value of the bubble point pressure.

摘要： An example method for determining a partial density of a compound in a downhole fluid may comprise exposing the downhole fluid to an electromagnetic radiation, and measuring a spectrum of radiation absorption by the downhole fluid. An absorption peak of the compound may be identified in the measured spectrum. A first parameter indicative of radiation absorption by the downhole fluid may be determined in the identified absorption peak. Second and third parameters indicative of radiation absorptions by the downhole fluid may be determined essentially out of the identified absorption peak. A weighted combination of the second and third parameters may be computed, and the partial density of the compound may be determined from a difference between the weighted combination and the first parameter.
