Abstract
Abstract An apparatus for preparing and testing fluid samples in which a two-phase fluid mixture passes through equipment for homogenizing the mixture with at least one isokinetic sampling device arranged to remove portions of the homogenized fluid mixture, with the portions then being passed through testing equipment. Preferably, geothermal fluid is homogenized and samples are withdrawn by the isokinetic sampling device and tested for various properties of the fluid, particularly the formation of scale. The testing apparatus is adapted for on-site operation.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
76 words
An apparatus for preparing and testing geothermal fluid samples comprising: (a) means for homogenizing a two-phase fluid mixture of geothermal liquid, steam and non-condensable gases, (b) at least one means for isokinetic sampling arranged to remove portions of the fluid discharged from said homogenizing means, and (c) means for monitoring scaling caused by said two-phase fluid mixture consisting of measurement of scale deposited by the removed portions passing through a constantly enlarging section of conical pipe.
Claim 2
Independent Claim
76 words
An apparatus for preparing and testing geothermal fluid samples comprising: (a) means for homogenizing a two-phase fluid mixture of geothermal liquid, steam and non-condensable gases, (b) at least one means for isokinetic sampling arranged to remove portions of the fluid discharged from said homogenizing means, and (c) means for monitoring scaling caused by said two-phase fluid mixture consisting of measurement of scale deposited by the removed portions passing through a constantly enlarging section of conical pipe.
Claim 3
Independent Claim
78 words
An apparatus for preparing and testing geothermal fluid samples comprising: (a) means for homogenizing a two-phase fluid mixture of geothermal liquid, stream and non-condensable gases, (b) at least one means for isokinetic sampling arranged to remove portions of the fluid discharged from said homogenizing means, and (c) means for monitoring scaling caused by said two-phase fluid mixture consisting of measurement of scale deposited by the removed portions passing through a pipe of cross-section that increases in abrupt steps.
Claim 4
Independent Claim
78 words
An apparatus for preparing and testing geothermal fluid samples comprising: (a) means for homogenizing a two-phase fluid mixture of geothermal liquid, stream and non-condensable gases, (b) at least one means for isokinetic sampling arranged to remove portions of the fluid discharged from said homogenizing means, and (c) means for monitoring scaling caused by said two-phase fluid mixture consisting of measurement of scale deposited by the removed portions passing through a pipe of cross-section that increases in abrupt steps.
Claim 5
Dependent Claim
17 words
An apparatus of claim 1 or 2 wherein said apparatus is mounted on platform provided with skids.
Claim 6
Dependent Claim
20 words
An apparatus of claim 3 wherein power units for operation of components of the apparatus are mounted on this platform.
Claim 7
Dependent Claim
81 words
A method for preparing and testing geothermal fluid samples comprising in an apparatus of claim 1: (a) passing a two-phase fluid mixture of geothermal liquid, steam and non-condensable gases through said means for homogenizing to produce a homogenized two-phase fluid mixture, (b) isokinetically separating portions of said homogenized mixture, and (c) testing the separated portions to monitor scaling caused by said fluid mixture by measuring the scale deposited by the separated portions passing through a constantly enlarging section of conical pipe.
Claim 8
Dependent Claim
83 words
A method for preparing and testing geothermal fluid samples comprising in an apparatus of claim 2: (a) passing a two-phase fluid mixture of geothermal liquid, steam and non-condensable gases through said means for homogenizing to produce a homogenized two-phase fluid mixture, (b) isokinetically separating portions of said homogenized mixture, and (c) testing the separated portions to monitor scaling caused by said fluid mixture by measuring the scale deposited by the separated portions passing through a pipe of cross-section that increases in abrupt steps.
Claim 9
Independent Claim
101 words
An apparatus for preparing and testing geothermal fluid samples comprising: (a) means for homogenizing a two-phase fluid mixture of geothermal liquid, steam and non-condensable gases, (b) at least one means for isokinetic sampling arranged to remove portions of the fluid discharged from said homogenizing means, (c) means for separating the liquid phase from the vapor phase of the removed portions of fluid thereby to monitor scale deposited in the separated liquid phase, and (d) means for monitoring scaling caused by said liquid phase consisting of measurement of scale deposited by said separated liquid phase passing through a pipe filled with rocks.
Claim 10
Independent Claim
101 words
An apparatus for preparing and testing geothermal fluid samples comprising: (a) means for homogenizing a two-phase fluid mixture of geothermal liquid, steam and non-condensable gases, (b) at least one means for isokinetic sampling arranged to remove portions of the fluid discharged from said homogenizing means, (c) means for separating the liquid phase from the vapor phase of the removed portions of fluid thereby to monitor scale deposited in the separated liquid phase, and (d) means for monitoring scaling caused by said liquid phase consisting of measurement of scale deposited by said separated liquid phase passing through a pipe filled with rocks.
