Данное приложение предназначено для учебного ознакомления с лабораторными исследованиями керна нефтяных и газовых скважин. Пользователю предлагается в полу-игровой форме провести измерения на различных лабораторных приборах, имитирующих работу реальных установок. Пользователь получает образец керна с заранее неизвестными свойствами, которые нужно определить. Переходя от одного уровня-сцены к другому, пользователь проводит эксперименты как лаборант в реальной петрофизической лаборатории. Приложение позволяет получить исходные данные для построения петрофизических связей пористость - проницаемость - остаточная водонасыщенность. Приложение разработано для личного использования и не подразумевает широкого распространения.
