INFILL DEVELOPMENT PREDICTION SYSTEM

A method, apparatus, and program product may build parent-child well pairs from data associated with one or more wells in a basin and use one or more parameters associated with such well pairs to train or use a machine learning model to predict a production impact of an infill well on one or more neighboring wells in the basin.

Multi-layer gas reservoir field development system and method

Provided are embodiments for hydrocarbon reservoir development that include the following: identifying proposed well locations within a reservoir boundary, for each location, developing a well plan by: (a) identifying layers of the reservoir located below the proposed location; (b) iteratively assessing the layers (from deepest to shallowest) to identify a deepest “suitable” layer that is not dry, congested, or unsuitable for gas production; and (c) performing the following for the identified layer and the location: (i) determining a borehole configuration for the location; (ii) determining a completion type for the location; and (iii) determining a stimulation treatment for the location, where a well plan for the location (e.g., for use in developing the reservoir) is generated that specifies some or all of a well location, the target layer, a borehole configuration, a completion type, and a stimulation treatment that corresponds to those determined for the proposed well location.

Method for Forming High Efficiency Geothermal Wellbores

Wellbore synthesis techniques are disclosed suitable for use in geothermal applications. Embodiments are provided where open hole drilled wellbores are sealed while drilling to form an impervious layer at the wellbore/formation interface. The techniques may be chemical, thermal, mechanical, biological and are fully intended to irreversibly damage the formation in terms of the permeability thereof. With the permeability negated, the wellbore may be used to create a closed loop surface to surface geothermal well operable in the absence of well casing for maximizing thermal transfer to a circulating working fluid. Formulations for the working and drilling fluids are disclosed.

CHARACTERIZING GEOLOGIC AREAS BASED ON COMPARATIVE COMPOSITIONAL ANALYSIS
20230175369 · 2023-06-08 ·

The invention disclosed herein provides methods for analyzing oil production properties of an oil well. Methods comprise comparing characteristics of one or more samples of solid material (e.g., petroleum cuttings) or fluids with a produced fluid. Comparative analyses can occur between samples collected within a single well or across two or more wells. Select compounds, such as hydrocarbons, and select relationship(s) between compounds such as ratios of directly measured compounds or, e.g., classes thereof, are typically used in the methods; select methods (e.g., gentle volatiles extraction) are typically used to derive the compounds; or both. In a first exemplary application, methods herein are used to identify locations of relatively higher likelihood of petroleum productivity within a well. In a second exemplary application, methods are used to identify the likelihood of shared source locations (provenance) between oil samples.
