Stability is important for both, reservoir rocks and bore holes. Wellbore stability is crucial to reach the reservoir in general and finally to extract hydrocarbons. It is of particular sensibility in anisotropic rocks, such as shale. With the increasing importance of unconventional reservoirs the topic of wellbore stability will be in the focus of gas & oil industries in the future.
Stability of the reservoir encompasses several problems: wellbore breakouts, sanding, which may lead to the shutdown of a well, and subsidence during or after production, which may damage wide superficial areas on top of a reservoir.
To avoid both, wellbore failure, sanding and reservoir collapse, an intimate knowledge of the geomechanical characteristics of shales and sandstones is essential for the economic success of each oil & gas field development project. Gesteinslabor with its undeniable experience and accuracy in the investigation of clastic rocks can aid in fruitful translation into action of each newly endangered drilling project.
Recently, the article "Determination of capillary threshold pressure with hydrogen gas" was published in the journal EEK.
Gesteinslabor has successfully completed the development of a new test rig to determine the capillary threshold pressure with hydrogen.
