FIELD OF THE INVENTION 
       [0001]    The present invention generally pertains to (i) an NMR/MRI-based integrated system and to (ii) an NMR/MRI-based and at least one non-NMR/MRI- analysis means integrated system for analyzing and treating of a drilling mud for drilling mud recycling process and to feedbacked methods thereof. The invention also related to means and both physical and chemical methods of analyzing drilled products and for analyzing engineering-related parameters of the drilling. 
       BACKGROUND OF THE INVENTION 
       [0002]    We were learning form Coussot et al.,  Oil  &amp;  Gas Science and Technology—Rev. IFP , Vol. 59 (2004), No. 1, pp. 23-29, that drilling muds are very complex fluids used to drill oil wells; their functions are various: to carry the rock cuttings to the surface, to maintain a sufficient pressure against the rock formation, to lubricate and cool the bit. There are a few families of drilling muds: oil based muds (invert emulsion of brine into an oil phase with various additives) and water based muds (aqueous solutions of clays and polymers). Originally prepared from produced oil, oil based muds formulations have evolved to very complex compositions of various additives. The base oil may be of various nature, and additives are very complex: water droplets, surfactants, organophilic clays, viscosifyers, various solids and others. These additives give specific properties to the mud, particularly regarding rheological properties. Drilling muds are often described as thixotropic shear thinning fluids with a yield stress. Due to their complex composition, drilling muds exhibit an internal structure which is liable to modify according to the flowing and shear conditions, which may lead to non-homogenous phenomena. It is therefore important to develop investigation techniques allowing visualizing the internal structure of the fluid in parallel to rheological measurements. 
         [0003]    Coussot et al further presented rheological experiments coupled to magnetic resonance imaging (MRI). Using this technique, they have determined the velocity profile in a viscometric flow. 
         [0004]    Coussot et al did not disclose or taught use of MRI in returning mud treatment, as be disclosed below. 
         [0005]    More about the aforesaid drilling muds: water-based mud (WBM) is a most basic water-based mud system begins with water, then clays and other chemicals are incorporated into the water to create a homogenous blend resembling something between chocolate milk and a malt (depending on viscosity). The clay (called “shale” in its rock form) is usually a combination of native clays that are suspended in the fluid while drilling, or specific types of clay that are processed and sold as additives for the WBM system. The most common of these is bentonite, frequently referred to in the oilfield as “gel”. Gel likely makes reference to the fact that while the fluid is being pumped, it can be very thin and free-flowing (like chocolate milk), though when pumping is stopped, the static fluid builds a “gel” structure that resists flow. When an adequate pumping force is applied to “break the gel”, flow resumes and the fluid returns to its previously free-flowing state. Many other chemicals (e.g. potassium formate) are added to a WBM system to achieve various effects, including: viscosity control, shale stability, enhance drilling rate of penetration, cooling and lubricating of equipment. Oil-based mud (OBM) can be a mud where the base fluid is a petroleum product such as diesel fuel. Oil-based muds are used for many reasons, some being increased lubricity, enhanced shale inhibition, and greater cleaning abilities with less viscosity. Oil-based muds also withstand greater heat without breaking down. The use of oil-based muds has special considerations. These include cost, environmental considerations such as disposal of cuttings in an appropriate place to isolate possible environmental contamination and the exploratory disadvantages of using oil based mud, especially in wildcat wells due inability to analyze oil shows in cuttings, because the oil based mud has fluorescence confusing with the original oil of formation. Therefore induces contamination of cuttings samples, cores, sidewall cores for geochemical analysis of TOC and masks the real determination of API gravity due to this contamination. Synthetic-based fluid (SBM) is a mud where the base fluid is a synthetic oil. This is most often used on offshore rigs because it has the properties of an oil-based mud, but the toxicity of the fluid fumes are much less than an oil-based fluid. 
         [0006]    On a drilling rig, mud is pumped from the mud pits through the drill string where it sprays out of nozzles on the drill bit, cleaning and cooling the drill bit in the process. The mud then carries the crushed or cut rock (“cuttings”) up the annular space (“annulus”) between the drill string and the sides of the hole being drilled, up through the surface casing, where it emerges back at the surface. Cuttings are then filtered out with either a shale shaker, or the newer shale conveyor technology, and the mud returns to the mud pits. The mud pits let the drilled “fines” settle; the pits are also where the fluid is treated by adding chemicals and other substances. 
         [0007]    The returning mud can contain natural gases or other flammable materials which will collect in and around the shale shaker/conveyor area or in other work areas. Because of the risk of a fire or an explosion if they ignite, special monitoring sensors and explosion-proof certified equipment is commonly installed, and workers are advised to take safety precautions. The mud is then pumped back down the hole and further re-circulated. After testing, the mud is treated periodically in the mud pits to ensure properties which optimize and improve drilling efficiency, borehole stability, and other requirements listed below. 
         [0008]    Drilling muds are classified based on their fluid phase, alkalinity, dispersion and the type of chemicals used. Dispersed systems are Freshwater mud - Low pH mud (7.0-9.5) that includes spud, bentonite, natural, phosphate treated muds, organic mud and organic colloid treated mud. High pH mud example alkaline tannate treated muds are above 9.5 in pH. Water based drilling mud that represses hydration and dispersion of clay—There are 4 types: high pH lime muds, low pH gypsum, seawater and saturated salt water muds. Non-dispersed systems are low solids mud—These muds contain less than 3-6% solids by volume and weight less than 9.5 lbs/gal. Most muds of this type are water-based with varying quantities of bentonite and a polymer. Emulsions usually selected from oil in water (oil emulsion muds) and water in oil (invert oil emulsion muds). Oil based muds contain oil as the continuous phase and water as a contaminant, and not an element in the design of the mud. They typically contain less than 5% (by volume) water. Oil-based muds are usually a mixture of diesel fuel and asphalt, however can be based on produced crude oil and mud, see M. G. Prammer, E. Drack, G. et al. 2001.

US &#39;726 further discloses an apparatus wherein its tool has a permanent magnet with a magnetic field direction substantially perpendicular to the axis of the borehole, a steel collar of a non-magnetic material surrounding the magnet, antenna positioned outside the collar, and a soft magnetic material positioned in a predetermined relationship with the collar and the magnet that helps to shape the magnetic field of the tool. Due to the non-magnetic collar, the tool can withstand the extreme conditions in the borehole environment while the borehole is being drilled. Motion management apparatus and method are employed to identify time periods when the NMR measurements can be taken without the accuracy of the measurement being affected by the motion of the tool or its spatial orientation.

         [0011]    An MRI/NMR-based means and methods for real-time in-vivo rheology measurements of drilling muds, especially for optimizing the recycling conditions and treatment of the mud, including continuous, one-step on-line measurement of mud-related parameters is still a long felt need. Moreover, such measuring system for defining mud characteristics, such as its fluid phase, alkalinity, dispersion and the type of chemicals used to be further add is an unmet need, currently necessary for optimizing and improve drilling efficiency, borehole stability, and other requirements as stated above.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0088]    The following description is provided, alongside all chapters of the present invention, so as to enable any person skilled in the art to make use of the invention and sets forth the best modes contemplated by the inventor of carrying out this invention. Various modifications, however, will remain apparent to those skilled in the art, since the generic principles of the present invention have been defined specifically to provide a means and method for integrating analysis and production of a food product. 
         [0089]    In some embodiments, an ingredient processing system interfaces between a mixing vat system of the food production line and the magnetic resonance device, which generates magnetic resonance images of the food flow, from which rheological parameters of the food product are determined. The ingredient processing system fulfills the NeSSI protocols and requirements. 
         [0090]    In the present invention, recent developments in industrial process improvement initiatives are adopted such as incorporating an on-line testing and adjusting system for iteratively adjusting the food product&#39;s ingredients. Another recent development incorporated in the present invention is the integration of sensing devices and monitoring processes into the sampling system. The mechanism preferably adopted is the NeSSI (New Sensors/Sampling Initiative). 
         [0091]    The NeSSI (New Sampling/Sensor Initiative) requirements fulfill the ANSI/ISA SP76.00.2002 miniature, modular mechanical standard and include mechanical systems associated with the fluid handling components. The ANSI/ISA standard is referenced by the International Electrotechnical Commission in publication IEC 62339-1:2006. Preferably, the food production line uses mechanical designs based on the ANSI/ISA SP76.00.02-2002 Standard. 
         [0092]    The NeSSI platform is a miniaturized, modular version of traditional sample gathering and handling methodologies, thus permitting the addition of components as standard modules, and the integration of the sensing system with the sampling system to form a single stand-alone unit for sample extraction and measurement. Using the NeSSI platform, process corrections may be detected earlier in the food product production line, thereby minimizing defective food production and food wastage. 
         [0093]    The Magnetic Resonance Device (MRD) of Aspect Imaging Ltd (IL and US) is typically useful for the drilling mud analysis, especially, as in the present invention, for managing ingredients. The MRD is a relatively small nuclear magnetic resonance device with about 1 Tesla magnetic field, on the order of 0.5 m×0.5 m×1 m in size. Thus, the MRD device is ideal for incorporating in an on-line system, especially, in the drilling mud recycling line. 
         [0094]    The radial shear stress distribution σ(r) is determined from

         [0106]    where Q si  is the standard quality parameter for the ith standardized sample of the food product, N is the number of standardized samples tested, and Q s  is the mean of the standard quality parameters Q si , 
         [0107]    In another embodiments, the check criterion is two standard deviations (95%) of the standard quality parameter Q s . In yet other embodiments, 3 or 4 standard deviations, or even more, are used as a check criterion. 
         [0108]    Reference is now made to  FIG. 1 , which shows an embodiment of the system. In this embodiment, the drilling mud  10  is in a drilling mud recycling line  12 . The drilling mud recycling line  12  comprises an ingredient supply device  32 , a drilling mud mixing vat system  14 , a flow conduit  24 , and a drilling mud recycling equipment  22 . It also comprises a magnetic resonance imaging device  26  encompassing at least a portion  28  of the flow conduit  24  and a processing system  30 . During operation of the drilling mud recycling line, a plurality of raw materials ingredients  16  are injected into the mixing vat system  14 , and are mixed until they form a drilling mud  18  of recycled drilling mud  10 . The drilling mud  18  is then injected via conduit  24  into drilling mud recycling equipment  22  and drilling mud  10  is produced in drilling mud recycling equipment  22 . 
         [0109]    The magnetic image resonance device  26  monitors the process in situ, on line and in real time. A sample of drilling mud  18  is injected into flow conduit  24 , such that the magnetic resonance imaging device  26  generates at least on magnetic resonance image of the drilling mud  18  flowing through the conduit  24 . The processing system  30  processes the at least one magnetic resonance image of the sample of the drilling mud  18  to generate a quality test parameter Q T , of the composition  18 , as described below. The quality test parameter Q T  is compared to a predetermined check value Q C , as described below, and if the difference is greater than a predetermined amount, the ingredient supply device  32  is instructed to supply a predetermined amount of at least one ingredient  16  to mixing vat system  14 . When the ingredient  16  has been incorporated into drilling mud  18 , another sample of drilling mud  18  is injected into flow conduit  24 , another at least one magnetic resonance image is generated, and the process is repeated iteratively until the quality test parameter Q T  differs from the predetermined check value Q C  by less than the predetermined amount. In a batch system, the process will terminate when mixing vat system  14  is empty, although no adjustments to the composition  18  are expected to be necessary after an acceptable composition has been attained, and the process will recommence when mixing vat system  14  has been refilled and a new batch of composition  18  has been produced. In a continuous process, there is continuous injection of ingredients  16  into mixing vat system  14 , so that the contents of mixing vat system  14  are constantly being replenished. 
         [0110]    The drilling mud recycling system  30  is configured to comply with ANSI/ISA SP76.00.2002 miniature, modular mechanical standard specifications. 
         [0111]    Reference is now made to  FIG. 2 , which presents further details of the drilling mud recycling line  12 , in accordance with a preferred embodiment of the present invention. As shown in  FIG. 2 , the drilling mud recycling line  12  comprises a vat  14 , a batch manifold  19  and control valve  21 , a pump  34 , a conduit  24 , and a food production device  22 . It further comprises an ingredient processing system  30  and an ingredient supply device  32 . 
         [0112]    The ingredient processing system  30  comprises a processor  42 , a memory unit  44  and a communications bus  46 , such as a NeSSI communications bus, enabling communications between all parts of the system. 
         [0113]    The ingredient processing system  30  communicates with the ingredient supply device  32  by means of a communications line  52 . The ingredient supply device  32  comprises a plurality of N ingredient reservoirs  54 . Typically, each reservoir  56  contains at least one ingredient, I i=j . Each reservoir  56  includes a communications port  60 , through which each reservoir  56  communicates with the communications line  52  via an internal communication bus  62 . 
         [0114]    In some embodiments, at least one reservoir 56 contains a mixture of at least two ingredients, I i=j, i=m . 
         [0115]    A batch of a sample of the drilling mud  10  is input into the vat  14  from a batch manifold  19  via a control valve  21 . A pump  34  pumps the drilling mud  18  of the sample from the vat  14  to the food production line  22  via nuclear magnetic imaging device  26 . A drilling mud flow  36  flows through the conduit  24 . At least a portion,  48 , of flow  36  passes through at least a portion of nuclear magnetic imaging device  26 , between entrance port  64  and exit port  66 . 
         [0116]    In further reference to  FIG. 2 , the nuclear magnetic imaging device  26 , which can be an NMR device, generates at least one magnetic resonance image  38  of the portion  48  of drilling mud flow  36  within the NMR device as a function of a radial location r, as is known in the art. The at least one magnetic resonance image  38  is processed by processor  42  to determine at least one radial velocity profile, υ(r),  40  of the composition  18 , where the radial parameter r is measured from the center of the conduit  24 , such that r=0 is the center of the conduit  24  and r=R is the edge of the flow  36 . The at least one magnetic resonance image  38  is transferred to the processor  42  via communication line  50  and communication bus  46 . In some embodiments, communication line  50  comprises part of communication bus  46 . 
         [0117]    As said above, drilling mud is used to control subsurface pressures, lubricate the drill bit, stabilize the well bore, and carry the cuttings to the surface, among other functions. As the drill bit grinds rocks into drill cuttings, these cuttings become entrained in the mud flow and are carried to the surface. In order to return the mud to the recirculating mud system and to make the solids easier to handle, the solids must be separated from the mud. 
         [0118]    It is thus according to one embodiment of the invention, wherein the following system is provided useful: In order to recycle drilling mud, solids control equipment are used, and a typical four stage solids control equipment used. In a first stage: Shale shaker is utilized: according to rig size, 1 to 3 sets shale shaker will be used at the first stage solids control separation, e.g., this is done with an API 4-0 60 shaker screens. Cutting over 400 μm are separated in this stage. Then a desander and desilter are used as the second and third stage separation. A mud cleaner are utilized for these stages. It is a combination of shake shaker, desander and desilter. For smaller size rigs (usually, under 750 hp), mud treated by shale shaker and mud cleaner can be used for drilling. In some condition, while drilling depth is big, and high standard mud request, decantering centrifuge will be used as forth stage separation. Finer solids are to be separated. For gas cut drilling mud, vacuum degasser, poor degasser and ignition device will be used. 
         [0119]    In parallel to the said mud-recycling scheme, an NMR/MRI-analyzing system is integrally utilized to improve the recycle of the used drilling mud and to restore its characteristics to a predefined scale of characteristics, by following the following scheme: (i) defining parameters and values of optimal frilling mud; (ii) on-line and in situ analyzing parameters and values of used frilling mud, preferably, yet not exclusively, along the initial stages of the recycle, when the drilling mud exit from the drilling hole; (iii) comparing said optimal parameters and values and said on-line acquired parameters and values, namely determining the differences between those predefined parameters and value of the ‘optimal drilling mud’ and correspondent parameters and value of the ‘actual drilling mud’, thereby defining which recycle step is required, and further defying parameters and values; such as recycling temperature, operation time of each of the recycling steps, type and quantity of raw materials to admix with said mud, admixing parameters etc, wherein the raw materials can be selected from water, bentonite and the like, calcium containing salts and compositions thereof, surfactant (anionic, cationic or zwitterionic surfactants, for example), fresh drilling mud, water immiscible solutions etc. (iv) recycling the used drilling mud whilst continuously NMR/MRI analyzing its properties, thus on-line feedbacking the recycling system, until the characteristics of the recycled drilling mud equal (plus minus an allowable predefined measure) the stored characteristics of the ‘optimal drilling mud’. Thus, this novel NMR/MRI-drilling mud recycling integrated-system, provides an on-line, in-situ, one-continuous-step drilling when an optimal drilling mud is utilized, namely a drilling mud having predefined characteristics, such as rheological characteristics, fluid phase characteristics, alkalinity (calcium content and the such), dispersion characteristics and so on and so forth. 
         [0120]    EP patent 0835463 discloses that NMR logging is a known method to determine these and other geologic formation parameters of interest. It is based on the observation that when an assembly of magnetic moments, such as those of hydrogen nuclei, are exposed to a static magnetic field they tend to align along the direction of the magnetic field, resulting in bulk magnetization. The rate at which equilibrium is established in such bulk magnetization upon provision of a static magnetic field is characterized by the parameter T 1 , known as the spin-lattice relaxation time. Another related and frequently used NMR logging parameter is the so called spin-spin relaxation time constant T2 (also known as transverse relaxation time) which is related to the relaxation due to non-homogeneities in the local magnetic field over the sensing volume of the logging tool. The &#39;463 patents further discloses a formation diffusion D which is dependent on the pore sizes of the formation. Mechanisms which determine the values of T 1 , T 2  and D depend on the molecular dynamics of the sample being tested. In bulk volume liquids, typically found in large pores of the formation, molecular dynamics is a function of molecular size and inter-molecular interactions which are different for each fluid. Thus, water and different types of oil each have different T 1 , T 2  and D values. 
         [0121]    According to one embodiment of the invention, thus, a time resolved or no-time resolved methods of analyzing drilling parameters, is provided useful, especially as defined in the integrated NMR/MRI drilling mud recycling system the above. The method comprising, inter alia, the following steps: at least one step of imaging and timing a series of NMR/MRI images of drilling mud before mud&#39;s re-used in a drilling hole (T influx ); either continuously of batch-wise flowing said time-resolved imaged drilling mud within said drilling hole whilst drilling said hole; after flowing period, i.e., time length between drilling mud influx and its outflow out from the hole, at least one step of imaging and timing a series of NMR/MRI images of drilling mud after the use in a drilling hole (T outflow ); comparing at least one parameter of said inflowing mud (timed at T influx ) and said outflowing mud timed (timed at T outflow ); thereby defining the change of said parameter and analyzing parameters related with the drilling: such as debris shape and size, particle distribution and smoothness etc. 
         [0122]    According to another embodiment of the invention, a similar method of analyzing drilled product is presented. This method comprises, inter alia, the following steps: at least one step of imaging and timing a series of NMR/MRI images of drilling mud before mud&#39;s re-used in a drilling hole (T influx ); either continuously of batch-wise flowing said time-resolved imaged drilling mud within said drilling hole whilst drilling said hole, thereby providing said drilling mus as a flowing carrier of the drilled product: such as solid ground, earth samples, water oil, gas, ores, coal etc); after flowing period, i.e., time length between drilling mud influx and its outflow out from the hole, at least one images of drilling mud after the use in a drilling hole (T outflow ); and and then comparing at least one parameter of said inflowing mud (timed at T influx ) and said outflowing mud timed (timed at T outflow ); thereby defining the change of said parameter and analyzing said drilled product. 
         [0123]    In those methods, the aforesaid step of comparing at least one parameter of said inflowing mud (timed at T influx ) and said outflowing mud timed (timed at T outflow ) may further comprising a step of measuring the relaxation time T 1 , T 2  and diffusion coefficient D as discussed above.
