Abstract: An apparatus for computing is presented that includes an input interface to receive a geological model, the geological model representative of a geological volume. The apparatus further includes a processor implementing a DNN, the processor configured to generate a probabilistic geological model that includes, for each cell, and for a set of facies, a probability of the cell being each of the facies, given the geological model and predetermined conditions, and an output interface. The conditions include: a style image, and hard data for regions of the geological volume. Further, a method includes obtaining a reconstruction of (i) a PCA vector obtained from a geological model, and (ii) a perturbed PCA vector created from the model, computing a set of NN weights for each of the reconstructioned vectors, computing a total loss, based on the respective NN weights, and computing an NN backpropagation based upon the total loss.

Abstract: A resource exploitation management system, method and a computer program product therefor. A description of new geological evidence for a geological resource is received, e.g., as one or more triples describing the evidence. Keywords in the description are matched against keywords in representations in a geological resource database. Geological relations are inferred from the descriptions and matched against predefined geological relations from the geological resource database. Consistent triple matches are merged with the geological resource database. The confidence level for merged matches is updated in the geological resource database.

Abstract: One aspect includes a method for determining a drilling plan for new wells in a reservoir. The method includes categorizing the new wells into at least a first new well and a second new well, such that a drilling location for at least the first new well must be determined imminently, but a drilling location for at least the second new well can be determined at a later time. The method further includes determining potential drilling locations for the second new well, determining the drilling location for the first new well based at least in part on the determined potential drilling locations for the second new well, and outputting the drilling plan comprising the determined drilling location for the first new well and the determined potential drilling locations for the second new well.

Abstract: A system, method and program product for generating an optimal field development plan (FDP) for the exploitation of oil and gas reservoirs when the available data of the reservoir is limited. A tree is generated starting from a root node wherein each node represents a decision or an observation of the field. The tree generation includes a specific manner of combining a search and a rollout process for exploring paths providing candidates of field development plans (FDP) and adding new nodes to the tree. The method reduces drastically the computational cost providing an affordable manner of estimating an optimal field development plan (FDP) before carrying out the exploitation of the reservoir.

Abstract: A method of data room content evaluation and a computer program product therefor. Valuation inputs indicate contents expected to be determined in a data room visit. A score range is selected for each valuation input and prior models are elicited. Conditional probabilities for a likelihood model are estimated interactively. Using estimated conditional probabilities the value of a visit or visits are calculated for subsequent analysis. Then, the value of data room visits may be determined by interactively analyzing estimated conditional probabilities.

Abstract: A system, method and computer program product for assessing field development plans selected based on a stochastic response surface, preferably, for hydrocarbon reservoir production. Assessment begins by assessing uncertainty associated with multiple decision variable configurations. A subset of realizations is selected. An individual surrogate is constructed for each subset realization. A reduced representative realization subset is determined, where the reduced subset is representative of the behavior/performance of all realizations of decision variable configurations.

Abstract: A system, method and program product for analyzing long term risk. A system is disclosed that includes a risk system for analyzing long-term risks, including: a risk knowledgebase that includes risk information associated with at least one domain; a risk model builder that builds a representation of a risk model based on inputs from a user interface and the risk knowledgebase, wherein the risk model includes risk factor nodes, risk event nodes and impact nodes; and a risk simulation engine that processes the representation and computes predicted outcomes.

Abstract: A risk modeling system, method and program product. A query orchestrator interfaces with users posing high-level queries and expanding high-level queries into lower level queries. A queryable risk extractor applies lower level queries to available risk-related knowledge to extract potential risks, e.g., to petrochemical resource production in a selected locale. A semantic enrichment unit applies semantic enrichment to extracted potential risks and selectively annotates the enriched results. A risk model builder generates a graphical risk model for display on a display. Risk analyst can use the graphical risk model to augment risk-related intelligence.

Abstract: The present invention is related to a method of generating a production strategy for the development of a reservoir of hydrocarbon in a natural environment by solving a minimization problem involving, among others, decisional variables, in such a way said decisional variables are reduced or even eliminated by combining them with other continuous variables. The reduction of decisional variables provides a high reduction of the computational cost. The elimination of all decisional variables allow a further reduction of the computational cost as solvers such as Mixed Integer Nonlinear Programming allowing the use of decisional variables that are not needed anymore. A particular case of decisional variables are binary variables.
