摘要： A method of quantitative analysis of drilling fluids comprising subjecting an untreated wet sample of the fluid to a reflectance infrared spectroscopy technique, typically attenuated total reflectance spectroscopy, and comparing the spectrum obtained with spectra obtained from calibration samples of fluids of known composition. The sample can be obtained directly from the flowing mud with no preparation or alternatively the sample might comprise a prepared sample which is re-suspended in a liquid phase carrier. The sample can also be analysed for non-spectral properties which might also provide useful information in conjunction with spectral data. The method requires little or no sample preparation and can be used to quantitatively analyse both water-based and oil-based drilling fluids using a continuous in-line and/or on-line arrangement.

摘要： A treatment process for an aqueous phase which contains oil droplets, possibly of 10-50 nm diameter, in aqueous flow from a hydrocyclone separator, comprises bringing the water into contact with a surface subdivided into areas of differing surface energy and affinity for oil and such that when the surface is submerged in an aqueous phase, oil droplets adhere to it with an apparent contact angle in a range from 90 to 150 degrees. Areas of the surface may reduce their affinity for oil in response to an external stimulus causing controlled release of droplets adhering to the surface. The process may be used to remove oil droplets from water produced by an oil or gas well, after downhole oil water separation or after production at a at a well head, or used to coalesce droplets in such water to a larger size to enable conventional separation.

摘要： The magnitude of asphaltic precipitation when injecting a viscosity reducing diluent into a reservoir formation, notably to assist oil recovery therefrom, is forecast by (i) determining a relationship between asphaltic precipitation and a solubility parameter for the diluted oil, and then (ii) utilizing that relationship to forecast the magnitude of asphaltic precipitation when injecting a predetermined viscosity reducing diluent into the formation. Making this forecast may be followed by injecting a viscosity reducing diluent into the formation to assist oil recovery. The diluent may in particular be supercritical carbon dioxide or other asphaltene precipitant mixed with a more polar material in proportions designed by forecasting asphaltic precipitation by candidate materials in possible proportions.

摘要： A process of making observations of a subterranean reservoir penetrated by a wellbore uses distinguishable sets of tracer particles and comprises steps of: (i) delivering a plurality of sets of tracer particles to respective subterranean locations via the wellbore, the particles in each set comprising a tracer substance which distinguishes that set form the other sets; (ii) causing or allowing the tracer substances to flow out from the tracer particles whilst the particles are at the respective subterranean locations; (iii) causing or allowing production of fluid out of said reservoir via the wellbore; and (iv) detecting the presence or absence of the tracer substances in the produced fluid. The tracer substances are sufficiently distinguishable from each other to enable a tracer substance detected in the produced fluid to identify the set of tracer particles from which it has come and hence identify the location from which it has come. The process may be used in conjunction with hydraulic fracturing, placing sets of particles at different locations within a fracture and/or in different fractures extending from a single wellbore.

摘要： A method of quantitative analysis of solids carrying drilling mud and removed from a drilling fluid circulating in a wellbore being drilled is described. The method comprises the steps of: sampling the removed solids, and analyzing the sample to determine the density of the solids and their weight fraction, drying a known weight of the sample to constant weight so as to obtain the solids in the form of dry solids, and analysis of the latter by an infrared spectroscopy technique. The concentration of the substances in the removed solids is then determined. The method can be applied to the control of the drilling operation by monitoring the quantity of products added to the drilling fluid, such as barite and polymers, or a product coming from the borehole wall or the underground formation being drilled. The invention also applies to the control of the working condition of the mud solids equipment.

摘要： In the rotary drilling of oil wells a drilling mud is used both to transport the cuttings up to the surface and to impose an hydrostatic pressure on the walls of the borehole. For these functions the mud must for example have an acceptable viscosity and density. It is therefore important to monitor the characteristics of the mud, and to keep them within certain limits. Only recently, however, has drilling practice recognized the importance of monitoring the mud's ionic composition. The various techniques proposed involve separation of the mud into liquid and solid portions, and analysis of these. Though they have proven useful, yet there are a number of problems. For example, the separation has not always been easy, and the available techniques often may not satisfactorily remove the fines. The invention suggests that these two problems, at least, can be overcome by the relatively simple expedient of first acidifying the mud sample, for acidification both causes the mud particles to flocculate, and so be more easily separated off, and causes the active fines to dissolve. In a preferred embodiment hydrobromic acid is employed, together with tetramethylammonium bromide (a displacement agent enabling the mud solid's Cationic Exchange Capacity to be measured), the separation is by filtration, and the analysis is by ion chromatography--and the results are fed into a computer model that then calculates the original mud components.
