Abstract: Some examples of an emulsion system for treating deep water blockage can be prepared by emulsifying a first aqueous phase in a first organic phase to prepare a first emulsion. A second aqueous phase can be emulsified in a second organic phase to prepare a second emulsion. The first emulsion and the second emulsion can be flowed into a subterranean formation. The first aqueous phase and the second aqueous phase, when mixed, can react to release nitrogen and heat.

Abstract: An aqueous iron sulfide dissolver including zinc, chromium, a methoxybenzoic acid, formic acid, acetic acid, and hydrochloric acid. The iron sulfide dissolver is made by combining these components, and dissolves compounds including iron sulfide upon contact. Evolved hydrogen sulfide reacts with the methoxybenzoic acid to yield solubilized methanethiol as an intermediate product, which is further oxidized to yield dissolved dimethyl disulfide.

Abstract: The present invention is an electrode array for neural stimulation suitable to be attached to neural tissue such that the attachment point acts as a fulcrum like point and contact with an end of the array body presses the other end of the array body into the neural tissue to be stimulated. This invention is particularly useful in a retinal electrode array for a visual prosthesis. By curving an electrode portion of an array body to approximate but not exceed (never more tightly curved) the curvature of the retina and applying force to the array by external means at the fulcrum like point, approximately even pressure across all electrodes is achieved.
