Abstract: A formation fluid sampling tool is provided with reactants which are carried downhole and which are combined in order to generate heat energy which is applied to the formation adjacent the borehole. By applying heat energy to the formation, the formation fluids are heated, thereby increasing mobility, and fluid sampling is expedited.

Abstract: Both a flow meter system and method are provided for accurately measuring the percentage amounts of liquid and gas phases in a multiphase flow through a conduit when the liquid phase constitutes a small minority portion (e.g., less than about 20%) of the multiphase flow. The system includes a flow meter that includes a differential pressure sensor connected across a Venturi in the conduit, and a dual energy fraction meter, each of which is operably connected to a digital processor. The system further includes a pump connected to the conduit upstream of the flow meter that introduces at least one pulse of a known quantity of liquid, the pulse being sufficient in volume to temporarily increase the liquid phase by a detectable amount. After the liquid pulse is introduced into the multi-phase flow, the digital processor computes the changes in the percentage amounts of the liquid and gas phases which should have occurred as a result of the pulse, and compares the computed changes with the actual changes measured by the flow meter in order to calibrate the flow meter. The measured increase in the liquid flow is then subtracted from the total measured liquid flow to determine the actual percentage of liquid flow.
Abstract translation: 提供了一种流量计系统和方法，用于当液相构成多相流的少量部分（例如，小于约20％）时，精确地测量通过导管的多相流中的液相和气相的百分比量。 该系统包括流量计，该流量计包括连接在管道中的文氏管两端的差压传感器，以及双能量分数表，每个能量分数表可操作地连接到数字处理器。 该系统还包括连接到流量计上游的导管的泵，其引入已知量的液体的至少一个脉冲，该脉冲的体积足以临时将液相增加可检测量。 在将液体脉冲引入多相流之后，数字处理器计算作为脉冲结果应该发生的液相和气相百分比的变化，并将计算出的变化与测量的实际变化进行比较 通过流量计来校准流量计。 然后从总测量的液体流中减去所测量的液体流量的增加，以确定液体流量的实际百分比。

Abstract: Measuring a parameter characteristic of a formation in an oil well with a device configured to generate a sensing field within a volume of the formation and cause a flow through the volume in the presence of the sensing field. The device also comprises sensors responsive to changes in the volume, which indicate existent amounts of fluid, such as hydrocarbon and water saturations and irreducible hydrocarbon and water saturations. Measurements may be made before the flow affects the measuring volume and after onset of the flow through the measuring volume.

Abstract: Methods and systems for testing a subterranean formation penetrated by a wellbore are provided. A testing tool has a plurality of packers spaced apart along the axis of the tool, and at least a testing port. The testing tool is positioned into the wellbore and packers are extended into sealing engagement with the wellbore wall, sealing thereby an interval of the wellbore. In some embodiments, the wellbore interval sealed between two packers is adjusted downhole. In one embodiment, the location of the testing port is adjusted between two packers. The methods may be used to advantage for reducing the contamination of the formation fluid by fluids or debris in the wellbore.
