The team is investigating elements in the mineral calcium carbonate, which were deposited in the mud and soil in and around a lake between two and 1.7 million years ago.
So a set of identification technique for thin reservoir with high mud and calcium content is developed and applied in new Wells interpretation and old Wells re-examination and obtains a nice effect.
为此，开发出一套高泥、高钙、薄储层油层识别技术，应用于新井解释及老井复查，效果很好。

Current drilling technology requests that polyanionic cellulose (PAC) has better properties to tolerate salt, calcium, high temperature, and enhance mud viscosity remarkably.
