Abstract: A method (50) and apparatus (60) for quantifying similarities between first and second cells (12a, 12b) in a mobile communications network (10) is provided. In particular, for each of the first cell and the second cell, a network node (60) receives input parameters, and based on those parameters, determines (54) respective sets of features for the cell. Each respective set of features defines a cell configuration and a coverage area morphology for the cell. So determined, a level of similarity between the first and second cells can be determined (56) based on their respective sets of features.

Abstract: This invention contains a method focused on increasing the water saturation of the reservoir by injecting industrial water into the well via SPU, thus diluting the concentration of salts, such as halite (sodium chloride). When the oil passes through the gas lift mandrel, this dilution will allow a part of the BSW water to evaporate, however, the amount of water that will remain in the oil will be sufficient to keep the salts in solution, thus scale formation will not occur and therefore no loss of production will occur. One of the focus areas of the method of this invention are high-temperature and low-BSW production reservoir wells. The solution of this invention minimizes the frequency of well treatments, avoiding loss of production due to well stoppage. The technical advantages of the method are increased reliability for SPU, increased NPV of operations and increased safety due to the reduction of operations with participation of the stimulation vessel.

Abstract: A method and apparatus extend existing cell parameter optimization techniques so that they can be used in cases where different cells are controlled by the same control element. Particularly, a coordination agent (46) receives an intermediate control decision for controlling a control element (48) shared by the plurality of cells (14). The coordination agent consolidates each of the received intermediate decisions into a single consolidated control decision, and sends the consolidated control decision to the shared control element. The control element then controls a network element (26) in each of the cells using the same consolidated control decision.

At least one source signal strength map is obtained. The at least one source signal strength map describes signal strengths in the at least one second frequency band for a coverage area of the wireless communication network. Based on the at least one source signal strength map and the predicted deviations of signal strengths, at least one target signal strength map describing signal propagation in the first frequency band for the coverage area is determined.

Abstract: The invention addresses to a method of applying a formulation obtained from a mixture of phosphonic salts and acids (R1—P(OR2) (OR3)), sulfonic acids (R—SO3H) and/or carboxylic acids (R—COOH). The pH of this formulation must be less than 3.5, preferably between 2.0 and 3.5. The formulation can be manufactured by dilution in saline fluid at the WSSV facility, in product compatible tanks on the rig or offshore platform or stimulation boat. This formulation enables acid stimulation and inhibition of the well in the same operation, in addition to removing damage caused by the use of organic acids in carbonate oil and natural gas reservoirs.
