Abstract
Abstract An oil well usually has a quantity of water admixed with the oil and it is frequently desirable to determine how much water is present. This invention provides a method and a tool which can be lowered into the oil well from the surface and whereby the relative amount of water admixed with the oil can be determined in situ at selected portions of the well through which the tool passes.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
164 words
An oil well tool for determining the proportions of water and oil in an oil well, comprising: a sample chamber having inlet and outlet ports; means for trapping a sample of the liquid in the oil well in the sample chamber, said means for trapping said sample of liquid including rotary inlet and outlet valves operatively connected with the inlet and outlet ports of said sample chamber and a port in said tool means for directing the flow of liquid in said well through the inlet valve, sample chamber and outlet valve and out to the exterior of the tool; means in said tool connected with said valves to rotate said valves to close said valves simultaneously to trap a sample in said chamber and means to open said valves simultaneously to open a port to direct the flow to bypass said sample chamber, and means at the surface for determining in situ the relative proportions of oil and water in said trapped sample.
Claim 2
Dependent Claim
164 words
An oil well tool for determining the proportions of water and oil in an oil well, comprising: a sample chamber having inlet and outlet ports; means for trapping a sample of the liquid in the oil well in the sample chamber, said means for trapping said sample of liquid including rotary inlet and outlet valves operatively connected with the inlet and outlet ports of said sample chamber and a port in said tool means for directing the flow of liquid in said well through the inlet valve, sample chamber and outlet valve and out to the exterior of the tool; means in said tool connected with said valves to rotate said valves to close said valves simultaneously to trap a sample in said chamber and means to open said valves simultaneously to open a port to direct the flow to bypass said sample chamber, and means at the surface for determining in situ the relative proportions of oil and water in said trapped sample.
Claim 3
Dependent Claim
21 words
The tool of claim 1 including means for passing the fluid in said well about said tool containing said trapped sample.
Claim 4
Dependent Claim
27 words
The tool of claim 1 including means to discharge said sample from said tool into the well and means for moving said tool to a new location.
Claim 5
Dependent Claim
102 words
A tool to determine the quantity of oil in the bore of an oil well, comprising an elongated tubular housing, said housing having a cylindrical chamber therein, rotary valve means at each of the upper and the lower ends of the chamber, motor drive means within the housing and operatively connected to both of said valve means to open and close said valve means, means remotely spaced from the motor means to control the operation of said motor means, electrode in said chamber extending lengthwise thereof, and an electrical circuit including the electrode and extending to a remotely spaced resistance recording means.
Claim 6
Dependent Claim
102 words
A tool to determine the quantity of oil in the bore of an oil well, comprising an elongated tubular housing, said housing having a cylindrical chamber therein, rotary valve means at each of the upper and the lower ends of the chamber, motor drive means within the housing and operatively connected to both of said valve means to open and close said valve means, means remotely spaced from the motor means to control the operation of said motor means, electrode in said chamber extending lengthwise thereof, and an electrical circuit including the electrode and extending to a remotely spaced resistance recording means.
Claim 7
Dependent Claim
38 words
A tool to determine the quantity of oil in the bore of an oil well as recited in claim 4 and ports in said housing and means to bypass fluid through said port on closure of said valves.
