A method for hydrocarbon production from a carbonate formation includes receiving a carbonate texture description of a drill cutting. A pre-defined grain fraction is assigned to the drill cutting based on the texture description. The pre-defined grain fraction is one of a set of pre-defined grain fractions and each pre-defined grain fraction of the set of pre-defined grain fractions corresponds to a respective one the set of carbonate texture descriptions. Based on the pre-defined grain fraction assigned to the drill cutting and a depth of the wellbore from which the drill cutting is taken, an estimated porosity of the drill cutting is determined using an algebraic equation, coefficients for which are determined by regression analysis using reference rock samples that have been assigned pre-defined grain fractions from the same set of pre-defined grain fractions.

Example methods and systems for geological interpretation in hydrocarbon exploration are disclosed. One example method includes obtaining a geological sketch of a first region, where the geological sketch includes a color-labeled image of the first region, and each color in the geological sketch represents a respective type of geological land cover in the first region.

The method includes training a machine learning model to determine a correlation between wireline logs obtained with down-hole logging tools and rock properties of a subsurface evaluated in the region of the well.

Example methods and systems for subsurface reservoir characterization are disclosed. One example method includes obtaining facies data of rock formations of a subsurface reservoir, where the facies data is from a forward stratigraphic modeling (FSM) process applied to the subsurface reservoir. A compaction-porosity model and an acoustic impedance-porosity model are selected from a library of rock physics models based on the facies data. An acoustic impedance model of the rock formations of the subsurface reservoir is determined based on the compaction-porosity model and the acoustic impedance-porosity model. The acoustic impedance model is provided for hydrocarbon exploration of the subsurface reservoir.
