A method for testing solid acid hydrolysis in a formation. The method includes introducing a test sample into a test cell, where the test sample includes an upper structure, a lower structure, and a solid acid disposed between the upper and lower structures. The pressure and temperature of the test cell are increased to simulate downhole conditions. A velocity of an acoustic p-wave and/or acoustic s-wave is through the test sample is measured while the temperature is increasing from an initial temperature to a final temperature. A temperature of onset of solid acid hydrolysis based on the measured velocity is determined.

Testing methodology to monitor the on-set of solid acid hydrolysis using sonic waves

A method of evaluating fluid sensitivity of a water-based muds on a shale rock. The method includes providing a sample of the shale rock from a portion of a formation, where the portion of the formation is positioned outside of a reservoir region. The sample of the shale rock is separated into a first portion and a second portion. The first portion is subjected to a UCS test for detecting a first uniaxial compressive strength (UCS) value (UCS). The second portion is converted into a prepared sample utilizing a test preparation procedure. The prepared sample is subjected to the UCS test for detecting a second UCS value (UCS). A fluid sensitivity index (FSI) is determined utilizing the detected UCSand USCvalues.

Fluid sensitivity evaluation method for superior water-based mud design

A testing system and method for evaluating the time required for shutting in a well after packing fractures in the well with a proppant having curable resin. At the well site, a sample of the proppant is compressed and heated in a portable unit. While the sample is being heated and compressed, its properties are being monitored to determine if the resin in the proppant has cured. Recording the time required for the proppant to cure provides an indication of how long to shut in the well after packing the fractures with the proppant. The portable unit includes a gas to fluid intensifier for compressively stressing the sample and a heat source for heating the sample. Sensors adjacent the proppant sample monitor the properties.
