A cutting tool with a cutting region and a connecting support region where the support region is designed to connect to an external motor assembly. The cutting tool is also has a porous region that is integrated within a portion of the tool such that as the tool cuts material the porous region can allow samples of the cut material to permeate into an internal chamber of the tool. Once in the internal chamber material samples can be analyzed in-situ for direct composition analysis.

Fluid control assemblies including at least one ring. The fluid control assemblies are used within core barrel assemblies to: provide an indication that a core barrel assembly has reached a drilling position and is latched to a drill string; serve as a mechanical shut-off valve that restricts the flow of drilling fluid within a core barrel assembly; and/or serve as a grease seal at the connection between an inner tube cap and an inner tube that receives a core sample.

A method may include obtaining various well logs or various core samples regarding a geological region of interest. The method may further include determining various permeability values, various porosity values, and various dolomite volume fraction values regarding the geological region of interest using the well logs or the core samples. The dolomite volume fraction values may correspond to a percentage of dolomite in a total mineral volume. The method may further include determining, using the porosity values, various permeability thresholds corresponding to various predetermined reservoir qualities. The method may further include generating, using the permeability thresholds, the permeability values, and the dolomite volume fraction values, a reservoir model including various dolomite boundaries defining the predetermined reservoir qualities. The method may further include determining a hydrocarbon trap prediction using the reservoir model.

A system for generating artificial permeability during the completion phase may include sensors that capture real-time data pertaining to a reservoir parameter, a formation parameter, or a tool condition parameter. The system may also include a drilling tool arranged in a wellbore to drill, using side drill bits, paths into a formation zone based on a drilling program. The system may also include an access module to access the real-time data captured by the sensors inside the well. The system may also include one or more processors configured to arrange the drilling tool in the wellbore, in proximity to the formation zone. The one or more processors may also be configured to cause an operation of the drilling tool based on the drilling program, update the drilling program based on the real-time sensor data, and cause an adjustment of the drilling of the paths based on the updated drilling program.
