20. A method for analyzing a subterranean formation, the method comprising:
(i) obtaining cuttings generated from drilling a wellbore that traverses the subterranean formation;
(ii) determining at least one of mineralogy, kerogen content, and kerogen maturity for the cuttings;
(iii) determining at least one of surface area and volume of pores within the cuttings;
(iv) determining porosity of the cuttings; and
(v) determining at least one of reservoir quality and completion quality using data obtained from processes (ii), (iii), and (iv);
designing an oil field service for the subterranean formation using at least one of the reservoir quality and the completion quality.
