[0157]

[0158] figure 1 A method 1000 of determining an oxidation-reduction potential 50 in a formation 10 having a surface 12 is shown.

[0159] The method 1000 includes the operation of placing 1100 a reference electrode 52 at the earth's surface 12 . A further operation is to penetrate 1200 or withdraw 1300 the probe 40 carrying the oxidation-reduction electrode 54 into the formation 10 . A further operation is to measure the 1400 oxidation-reduction potential 50 as the potential difference between the reference electrode 52 and the oxidation-reduction electrode 54 .

[0160]As an example, reference electrode 52 is placed at the surface of formation 10 . Afterwards, the drilling mechanism will perform the operation of penetrating 1200 the probe 40 into the formation 10 . The probe 40 carries an oxidation-reduction electrode 54 . Controller 30 in wireless or wired communication 32 with oxidation-reduction electrode 54 and reference electrode 52 will opera...

Abstract

An object of the invention is achieved by a system for determining in-situ oxidation-reduction potential in a formation having a surface separating the formation from an ambient atmosphere. The systemmay measure the oxidation-reduction potential in-situ, thereby the system may provide the most precise measurement of the oxidation- reduction potential. The surface of the formation may be the interface between the ambient atmosphere and the uppermost layer of the formation. In this application the surface is also referred to as the soil. The system may comprise a probe for a penetration into the formation. The probe may comprise an oxidation-reduction electrode. The system may comprise a reference electrode for placing on the surface of the formation. The system may comprise a controller, which may be configured to communicate with the probe. The controller may be configured to communicate with the reference electrode. The controller may further be configured to determine the oxidation-reduction potential as a potential difference between the reference electrode and the oxidation-reduction electrode. The controller may communicate with the probe, the oxidation-reduction electrode, the reference electrode or any other device by a wire or wireless or a combination of wire and wireless.

Description

technical field [0001] The present invention relates to methods, systems and probes for in situ determination of oxidation-reduction potentials in formations having a surface. [0002] The present invention relates to methods, systems and probes for in situ determination of resistivity in formations having a surface. Background technique [0003] Agriculture uses fertilizers such as ammonium nitrate to increase overall yields. Some of the fertilizers used seep to the surface and may seep further into the formation, which may have underground water reservoirs. As a result, groundwater reservoirs become contaminated with fertilizers, creating groundwater that may not be usable as drinking water without additional treatment. [0004] It is very difficult to prevent fertilizers from seeping into the ground, and it is also difficult to remove them. In some cases, highly contaminated soil has been physically removed, but this is an expensive and labor-intensive method. Further...
