摘要： A method for analysing a crude oil to determine the amount of organic acid compounds contained in the crude oil includes extracting the organic acid compounds from a sample of crude oil to form an extract and determining the amount of the extracted organic acids In addition, the method includes dissolving the extract in a polar solvent to form a solution of the extracted organic acid compounds Further, the method includes introducing a sample of the solution of the extracted organic acid to an apparatus including a reversed phase liquid chromatography (LC) column and a mass spectrometer (MS) arranged in series. The reversed phase LC column contains a hydrophobic sorbent and the mobile phase for the LC column includes a polar organic solvent. Still further, the method includes separating the organic acid compounds in the LC column of the LC-MS apparatus and continuously passing the separated organic acid compounds from the LC column to the MS of the LC-MS apparatus to ionize the organic acid compounds and to obtain a chromatogram with mass spectral data over time for the ionized organic acid compounds. Moreover, the method includes determining the area(s) under the peak(s) in an extracted ion chromatogram derived from the mass spectral data assigned to one or more organic acid compounds. The method also includes determining the amount of the organic acid compound(s) in the sample by comparing the area under the peak(s) assigned to the organic acid compound(s) with the area under a peak in an extracted ion chromatogram assigned to a specific amount of a standard organic acid compound. In addition, the method includes extrapolating from the amount of the organic acid compound(s) in the sample to provide the total amount of the organic acid compound(s) in the extract.

摘要： A method includes receiving data indicative of outputs of first and second seismic sensors. The outputs include components corresponding to the detection by the first and second seismic sensors of first and second seismic signals. In addition, the method includes identifying, relative to a first clock in the first seismic sensor, a first time associated with a time of arrival of the first seismic signal at the first seismic sensor, and a second time associated with a time of arrival of the second seismic signal at the first seismic sensor. Further, the method includes identifying, relative to a second clock in the second seismic sensor, a third time associated with a time of arrival of the first seismic signal at the second seismic sensor, and a fourth time associated with a time of arrival of the second seismic signal at the second seismic sensor. Still further, the method includes determining an offset of the first clock relative to the second clock using the first, second, third and fourth times.

摘要： A computer-implemented method for determining an amount of hydrocarbon fluid present in a rock of a hydrocarbon-producing reservoir is provided. The rock comprises organic matter and porous and permeable inorganic matter. The method comprises the steps of receiving data relating to chemical and kinetic properties of the organic matter, rock lithology data, rock thickness and reservoir temperature and pressure data, inputting the received data into a computer-implemented model, and operating the model. The model operates to a) simulate hydrocarbon fluid generation in the rock based on the input data and thereby determine an amount of generated hydrocarbon fluid, b) generate predicted data, and c) determine a total amount of hydrocarbon fluid present in the rock based on the predicted data. The generated predicted data is indicative of i) an amount of the generated hydrocarbon fluid adsorbed onto a surface of the organic matter within the rock, ii) an amount of the generated hydrocarbon fluid present in the pores of the organic matter by determining the porosity of the organic matter, based on the chemical and kinetic properties of the organic matter, and iii) an amount of the generated hydrocarbon fluid present in the pores of the inorganic matter by determining the porosity of the inorganic matter, based on the rock lithology data. A corresponding system, a computer program and a computer readable medium are also provided.

摘要： Method of performing a 3-D seismic survey using a plurality of vibroseis sources, and an array of seismic sensors arranged within a survey area. Each vibroseis source emits a distinctive acoustic signal and each seismic sensor of the array is in a continuous state of readiness to detect reflected acoustic signals. The method includes assigning vibroseis points (VPs) to each vibroseis source, moving each vibroseis source to assigned VPs where the vibroseis source emits an acoustic signal, recording the emission time of the acoustic signal by each vibroseis source at its assigned VPs together with the geographic position of the assigned VPs, continuously listening for reflected acoustic signals using the seismic sensors and recording a time domain record of the reflected acoustic signals received by each seismic sensor. Reflected acoustic signals associated with emission of an acoustic signal by a vibroseis source at an assigned VP are then determined.

摘要： Method of consolidating sand in a subterranean formation by contacting the sand in a first location in the presence of water with a slurry in a liquid medium of cement of average particle size less than 10 microns to produce a mixture including sand, water and cement, the slurry being injected into the formation to the location. A separation step is carried out in which a liquid hydrocarbon fluid is passed into the location to displace from the location at least some of the cement from the mixture. The volume ratio of liquid hydrocarbon fluid to the volume of the slurry injected to the formation is at least 5:1. The mixture is allowed to set to give permeable consolidated sand.

摘要： A method of determining rate and phase of fluid produced from or injected into a hydrocarbon well includes obtaining first temperature and pressure measurements from sensors at the well. The first temperature and pressure measurements are applied to a plurality of predictive well models to calculate an estimated value of fluid rate and phase composition from each of the predictive well models responsive to the temperature and pressure measurements. A first fluid rate and phase composition result is derived from the estimate value of fluid rate and phase composition from each of the predictive well models.
