Abstract

Methods and systems to monitor and analysis unconventional reservoirs with wellbores with a substantially horizontal section. Monitoring and analysis is conducted in three dimensions using high-resolution geochemical fingerprinting analyses of rock samples and produced oil samples. The invention uses methods to preserve, prepare, extract, and/or analyze hydrocarbons in the pore spaces of or adsorbed in organic-rich rock samples, such as, but not limited to, drill cuttings and drill cores, using one or more combinations of physical energy sources, including, but not limited to, thermal, vapor pressure, and mechanical stress. The collected samples are transported and prepared in low temperature conditions, with parts of subsequent processing at very low temperatures, thereby allowing a fuller measurement of geochemical fingerprints for the extracted hydrocarbons using various analysis tools. More particularly, the treatment and process allows geochemical fingerprinting to very low carbon number ranges. The techniques of the present invention may be used to optimize well stacking and spacing, completion design, and cluster efficiency evaluation to improve unconventional reservoir economics.
