20090118143 | Methods for Manipulation of the Flow of Fluids in Subterranean Formations - A method of treating a subterranean formation penetrated by a wellbore to mitigate the production of unwanted fluids from the wellbore is carried out by forming a treatment fluid containing at least one of an oil-wetting or water-repelling surfactant and a carrier fluid.

20100096129 | METHOD OF HYDROCARBON RECOVERY - A method is given for treating a wellbore to increase the production of hydrocarbons from a subterranean formation penetrated by a wellbore, involving a period of injecting into the formation an aqueous injection fluid having a different chemical potential than the aqueous fluid in the formation. If there is water blocking, an osmotic gradient is deliberately created to cause flow of water into the injected fluid; hydrocarbon is then produced by imbibition. If the pore pressure in the water-containing pores in the formation is too low, an osmotic gradient is deliberately created so that water flows from the injected fluid into the water-containing pores, increasing the pore pressure and facilitating hydrocarbon production by imbibition. The method may be repeated cyclically. A semipermeable membrane may be created to enhance the osmosis. Wetting agents may be used to influence imbibition. | 04-22-2010 |

The selection can be based on imbibition testing on material that has been disaggregated from the source formation. | 05-12-2011 |
20120151998 | WETTABILITY AND MATRIX IMBIBITION ANALYSIS - A method of determining wettability of a rock sample, such as from a core sample is described. The sample is preferably crushed or comminuted to a particulate size where micro fractures have been eliminated, but where the particles are still large enough to represent the native rock matrix and texture. The comminuted core sample is exposed to a test fluid for a given period of time. The rock sample can be split into many separate aliquots, and a series of tests is performed using a series of different fluids and/or the same fluid for different exposure times. The excess test fluid residing on the surfaces of sample particles is removed. The test fluid imbibed into the interior of the particulate sample is then measured. The test fluid can be, for example, water, a non-aqueous fluid, and/or a solution of miscible solvents. The technique used to measure the imbibed fluid depends on the solvent (imbibing fluid) being studied. In one example, this technique includes both gravimetric determination and quantitative chemical analysis. The detection of water can be via Karl Fischer titration. | 06-21-2012 |
20120152547 | WETTABILITY ANALYSIS OF DISAGGREGATED MATERIAL - A method for determining wettability of a solid, such as a reservoir rock material, is described. The method includes disaggregating the material, for example by grinding and placing the disaggregated material on the surface of the fluid. The wettability is analyzed based on whether a portion of the material floats on or sinks into the fluid. The method is well suited for heterogeneous solid materials that have mixed wetting characteristics and/or have varying surface types. The fluid can be evaluated as a potential treatment fluid or a component thereof that can be used for treating the rock formation. For example, the potential treatment fluid can include a surfactant or an oxidizing agent. A simple observation can be made whether substantially all of the material placed on the surface of the fluid sinks into the fluid, or the portions of floating and sinking material can be weighed. | 06-21-2012 |
