Abstract: A computer-implemented method and corresponding system for determining the concentration of one or more scale inhibiting polymers in a fluid received from one or more porous and permeable hydrocarbon-bearing rock formations is provided. Each polymer comprises a different chemical marker and the fluid comprises a plurality of commingled said scale inhibiting polymers. The method comprises receiving first input data representing a measured absorption spectrum, within a predetermined wavelength range, of the commingled scale inhibiting polymers, wherein the measured absorption spectrum is measured using a detector after chromatographic separation of the fluid; receiving second input data representing reference absorption spectra, the reference absorption spectra comprising: a) an absorption spectrum, over the predetermined wavelength range, of each of the scale inhibiting polymers; and b) baseline reference absorption spectra of other chemicals having absorbance values within the predetermined wavelength range that are expected to be present in the fluid; inputting the first and second input data into a computer program; and operating the computer program. The computer program is operated to, at each of a plurality of discrete time steps over an elution time from the separation, determine a factor for each reference absorption spectrum that results in a modelled spectrum comprising a best-fit linear combination of the second input data to the first input data. For each scale inhibiting polymer, the computer program also operates to use the factors corresponding to the absorption spectrum of said scale inhibiting polymer that have been determined for a predetermined number of said discrete time steps to determine an indication of the concentration of the scale inhibiting polymer.

Abstract: A member is moved within a well bore in a plurality of cycles, each cycle including holding the member in slips, releasing the slips, moving the member within the well bore and applying the slips. The hook load is measured at multiple points during each of these cycles and the plurality of measured values are used to identify data indicative of the forces on the member within the well bore.

Abstract: A method and a system are provided for determining the relative positions of a wellbore and an object. The wellbore is represented by a first ellipse and the object is represented by a second ellipse. The first ellipse represents the positional uncertainty of the wellbore and the second ellipse represents the positional uncertainty of the object. The method includes receiving input data relating to a measured or estimated position of the wellbore and the object. In addition, the method includes calculating an expansion factor representing an amount by which one, or both, of the first ellipse and the second ellipse can be expanded with respect to one or both of respective first and second sets of elliptical parameters so that the first and second ellipses osculate. Further, the method includes determining, based on the calculated expansion factor, position data indicative of the relative positions of the wellbore and the object.

They are preferably made by transesterification. Blends of such polymers and/or the corresponding homopolymers or copolymers of ester 1 and/or polyalkylene imines with long side chains, and optionally with monomeric polar additives may be used as inhibitors.

Abstract: The problem of lost circulation is pertinent to the oil industry. To prevent fluid loss, a lost circulation material (LCM), or more generally, a plugging material, can be used to effectively plug the fractures in the rock formation. If the fractures are in the production zone, it is also ideal to unplug them when the drilling operation is complete. Therefore, a material engineered to degrade after a desired period would be useful. In examples, a plugging material has been developed by gelling an oil-based fluid using a low molecular weight gelator, dibenzylidene sorbitol (DBS). DBS gels are robust and show plugging behavior. DBS is shown to chemically degrade in presence of an acid. Hence, a self-degrading gel can be synthesized by incorporating an acid into the system. Further, by varying the type and concentration of the acid, the degradation time of the gel can be controlled.

Abstract: In some examples, the disclosure provides a method for determining a drift in clock data that is provided by a clock of a seismic sensor. The sensor is exposed to an ambient temperature that varies over time. The method includes obtaining temperature data associated with the ambient temperature as a function of time. The method also includes obtaining the clock data. The method also includes obtaining timestamp data provided by a global navigation satellite system. The method also includes determining drift data which minimizes a difference of a temporal drift in the clock data, based on the timestamp data and the temperature data. The method also includes outputting corrective data based on the determined drift data.
