Abstract: A method for generating a flow profile of a wellbore whereby a first measurement and a second measurement are collected for each point of a sequence of selected points along the wellbore. For each respective point in the sequence of points, the arithmetic difference between the first and second measurements collected for the respective point is calculated, and the summation of the arithmetic differences for the respective point and for each point which follows the respective point in the sequence of points is recorded. A flow profile of the wellbore is generated by plotting the value of the summations calculated for each point of the sequence of points, wherein the magnitude of the potential productive flow from that point in the wellbore, is substantially proportional to the magnitude of the slope of the profile corresponding to that point.

Abstract: A method for generating a flow profile of a wellbore whereby a resistivity tool is run through the wellbore, while the wellbore is being drilled, to sequentially measure and record, at each of a sequence of selected points along the wellbore, a sequential series of resistivities measured while drilling (MWD). Fluid from the wellbore is then allowed to permeate into the formation. The resistivity tool is then run through the wellbore, after the drilling mud has permeated into the formation, to sequentially measure and record, at substantially the same points at which the MWD resistivity measurements were made, a sequential series of resistivities measured after drilling (MAD). For each point, the arithmetic difference between the MWD resistivity and the corresponding MAD resistivity recorded for the respective point is calculated.

Abstract: Hydraulic fracture extension in earth formation zones of interest may be monitored by placing one or more monitor wells in predetermined positions on opposite sides of an azimuth aligned with the expected fracture plane extending from a fluid waste injection well. The monitor wells are provided with arrays of vertically spaced triaxial geophone units and the signals from the geophones are transmitted to a central processing unit for treatment and analysis to determine the location of micro-earthquake events which occur as the fracture propagates radially and, usually, vertically away from the injection well. Geophone signals are converted to digital format and selectively stored on magnetic tapes or in a shared memory of a central processing unit which is operable to display selected channels for geophone signals in a way so that minimum arrival time of a signal at a particular geophone will indicate the growth of the fracture in real time to control fluid waste disposal, for example.

Abstract: Heavy crude oil is recovered and processed at a refinery through (a) a distillation zone(s), (b) a solvent deasphalting unit (c ) a high pressure air partial oxidation gasifier to produce a CO-rich gas mixture including hydrogen, (d) a shift reactor and (e) a purification step to produce 99.9% pure hydrogen. The hydrogen is used to treat a deasphalted oil fraction and distillate hydrocarbon fractions obtained from the crude oil. The process is considered integrated in the sense that the purified hydrogen recovered from the heavy crude oil is used to treat hydrocarbons recovered from the same crude oil.
