摘要： A process of designing a screenless completion for an oil or gas well includes selecting an oil or gas well having known characteristics and inputting data about them into a computer; determining, through operation of the computer, whether a screenless completion should be performed on the selected well and, if so, identifying materials to be used in the screenless completion and in response indicating to a user a screenless completion design using the identified materials. Different types of screenless completion designs are made available. These steps can be performed for multiple wells, preferably with similar results for similar wells.

摘要： An aqueous-swellable and degradable diverting system and the use of the system in treating a subterranean formation penetrated by a wellbore. The diverting system includes a carrier fluid and a partially dehydrated or anhydrous borate source material that does not swell or does not swell substantially when placed in contact with the carrier fluid. The carrier fluid is capable of carrying and placing the borate source material into a stimulation network substantially distanced from a wellbore. Exposure of the diverting composition to a sufficient amount of aqueous fluid swells the borate source material, bridges a desired portion of the stimulation network, and then dissolves at least a portion of the diverting composition. The diverting techniques allow for treatment in a subterranean formation to be diverted to a previously untreated portion of the formation, in particular a portion of the formation that is significantly distanced from the wellbore.
