Abstract
Abstract The means and method of the present invention includes a source of microwave energy and associated elements which provide microwave energy to a petroleum stream. Other circuitry include elements which receive microwave energy from the petroleum stream. Electronic apparatus provides at least two outputs utilizing the provided microwave energy, the received microwave energy and known values for 100 percent oil, 100 percent solids of one specie and 100 percent water, corresponding to different ratios of ratios involving oil and water, oil and solids, and water and solids.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
85 words
Means of analyzing a petroleum stream having oil, water, and solids of one species comprising: providing means for providing microwave energy to the petroleum stream, receiving means for receiving microwave energy from the petroleum stream, and output means connected to the providing means and to the receiving means for providing at least one output, utilizing the provided microwave energy, the received microwave energy and known values for 100 percent oil, 100 percent solids, and 100 percent water, corresponding to a ratio of solids to liquid.
Claim 2
Dependent Claim
85 words
Means of analyzing a petroleum stream having oil, water, and solids of one species comprising: providing means for providing microwave energy to the petroleum stream, receiving means for receiving microwave energy from the petroleum stream, and output means connected to the providing means and to the receiving means for providing at least one output, utilizing the provided microwave energy, the received microwave energy and known values for 100 percent oil, 100 percent solids, and 100 percent water, corresponding to a ratio of solids to liquid.
Claim 3
Dependent Claim
16 words
The analyzing means as described in claim 1 in which the output means includes computer means.
Claim 4
Independent Claim
66 words
A method for analyzing a petroleum stream having oil, water and solids comprising the steps of: providing microwave energy to the petroleum stream, receiving microwave energy from the petroleum stream, providing at least one output, utilizing the provided microwave energy, the received microwave energy and known values for 100 percent oil, 100 percent solids and 100 percent water, corresponding to a ratio of solids to liquid.
Claim 5
Independent Claim
66 words
A method for analyzing a petroleum stream having oil, water and solids comprising the steps of: providing microwave energy to the petroleum stream, receiving microwave energy from the petroleum stream, providing at least one output, utilizing the provided microwave energy, the received microwave energy and known values for 100 percent oil, 100 percent solids and 100 percent water, corresponding to a ratio of solids to liquid.
Claim 6
Dependent Claim
55 words
A method as described in claim 3 in which the step of providing at least one output includes: relating known values of 100 percent oil, 100 percent solids and 100 percent water to the phase difference between the provided microwave energy and the received microwave energy and to the intensity of the received microwave energy.
Claim 7
Dependent Claim
73 words
A method as described in claim 4 in which the step of providing at least one output further includes: generating a map utilizing points derived from the known values of 100 percent oil, 100 percent water and 100 percent solids, determining a measurement point within the map utilizing the provided microwave energy and the received microwave energy, and providing two outputs in accordance with the relationship of the measurement point to the map.
Claim 8
Dependent Claim
63 words
