Well Correlation (local-first)
Lay wells side by side in MD, TVD subsea or flattened on a top, pick tops safely and check them with tops QC, and add lithology and core tracks.
Features
From well logs to defensible capital decisions
RRS is built for petrophysicists, reservoir engineers, economists, and asset teams who need one connected path: formation evaluation on your machine, probabilistic volumetrics, investment economics, scenario planning, and decision reporting, without copy-paste drift between tools. Well log files and interpretation cases stay in a project folder you choose and every log format, DLIS included, is parsed in the browser; only the optional CSV imports on other modules touch the server, and CSV never stores your file.
Formation Evaluation (local-first)
Load LAS and DLIS well logs into a browser petrophysics workspace: log viewer, Vsh, porosity, Sw, net pay, crossplots (neutron–density, Pickett, Hingle, M–N, Buckles, GR histogram), results, and sensitivity. 7 Sw model families (Archie, Simandoux, Modified Simandoux, Indonesia, dual-water, Waxman-Smits, and Juhasz).
Volumetrics & reservoir uncertainty
Run deterministic and Monte Carlo workflows with explicit assumptions for reservoir risk quantification. 7 distinct saturation model families across Formation Evaluation and Volumetrics combined, with tornado sensitivity and Spearman rank drivers.
Investment & economics
Decline-driven multi-asset cash flow with tax, royalty, opex escalation, abandonment, and carbon pricing stated explicitly, then NPV and IRR as distributions rather than a single point.
Scenario Planning
Rank development cases against NPV, IRR, and payback thresholds, solve break-even price, capex, and opex, and weight named scenarios by probability for an expected value with a waterfall showing where the value moved.
Decision Dashboard
Put the ranked cases on a single NPV scale with sensitivity context and a cross-module run manifest, so a reviewer is not asked to compare charts with different axes, then export the comparison as CSV or PDF.
Executive Summary
Snapshot the same workspace into the memo that leaves the room with the decision: headline numbers, the assumptions behind them, and the narrative, generated in your browser as a PDF or a structured CSV.
Connected workflow
7 integrated modules, Well Correlation through Executive Summary, with explicit handoffs instead of silent overwrites between petrophysics, volumetrics, economics, and scenarios.
