Pertamina (Persero) | | **Pricing** | Free | | **Platforms** | iOS | | **Confidence** | Low (0.25/1.0) | | **Data Age** | 30d | ## Metadata & Market Performance - **Publisher:** PT. Pertamina (Persero) - **Category:** Utilities - **Target Audience:** Oil and gas industry professionals, specifically those engaged in drilling operations and planning. - **Platforms:** iOS - **Version Audited:** 2.0 - **Audit Date:** 2026-06-02 - **Signal Count:** 6 reviews analyzed - **Confidence:** Low (0.25/1.0) - **App Store ID (iOS):** 891302915 - **Bundle ID:** com.pertamina.drilling - **Performance Trend:** Declining - **Data Window:** Analysis based on signals collected up to 2026-06-02 ## Executive Snapshot **What it is:** Drilling Engineering is a technical utility app for oil and gas professionals, providing drilling calculations and diagnostic logic on iOS. **Why users hire it:** Users hire this app to perform critical, IADC-based safety and design calculations in the field, where the cost of error is high and speed is essential. ## App DNA (Features & Intent) - **[Differentiator] Stuck Pipe Problem Identification:** Diagnostic logic based on Texas Drilling Associates methodology. * *User Intent:* Users seek enhanced value through premium features. - **[Differentiator] Well Control Kill Sheet:** IADC-based calculation tool for managing formation influx. - **[Standard] Drilling Calculator:** Suite of 90 base calculations for drilling operations. ## Market Position {#market-position} The app maintains a niche utility position with a 3.79 rating, but the lack of updates since 2017 limits its ability to compete with modern, frequently updated industrial tools. ## Monetization Strategy - **Model:** Free - **Tiers:** Free - **Analysis:** The application is provided as a free utility to support industry professionals. ## SWOT Analysis {#swot} **Core Strengths:** - Diagnostic logic based on Texas Drilling Associates methodology - IADC-based kill sheet calculations for industry compliance **Critical Frictions:** - Stagnant codebase since 2017 - Lack of offline-first architecture for remote field sites **Growth Levers:** - Integration of offline-first calculation engines - Addition of task-specific calibration tools for remote drilling sites **Market Threats:** - New entrants with offline-first capabilities - Competitors with modern, frequently updated interfaces ## Recent Changes (v2 → v3) {#recent-changes} The competitive analysis has been updated to benchmark the app against specialized industrial utilities rather than general-purpose calculators, emphasizing the lack of offline-first capabilities as a primary competitive disadvantage. **Overall trend**: Declining **Compared at**: 2026-06-02 ### High-impact changes - **[Added] Offline-first architecture requirements** (swot) — Added 'Lack of offline-first architecture' as a weakness and 'New entrants with offline-first capabilities' as a threat. - **[Shifted] Competitive benchmarking** (positioning) — Shifted from comparing against a single general-purpose calculator to a set of six specialized industrial utility apps. ### Medium-impact changes - **[Added] Feature gap identification** (features) — Added specific gaps for offline-first calculation engines and direct technical support integration. ## What's New - **Latest (v2.0, 8 years ago):** Added new formulas (including cementing) and new themes. ## App Momentum (Zombie) {#momentum} - No updates since 2017. - Maintenance mode status. > **Cadence:** 1 total versions · 1 majors in last 6 months · 3108 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Drilling Engineering is an established utilities app that is completely free. With a 3.79/5 rating from 19 reviews, it shows polarized user reception. > **Bottom Line:** The app provides essential technical utility, but the 2017-era codebase creates a significant churn risk against modern, offline-capable competitors, so the team must prioritize an infrastructure refresh to maintain relevance. **Best for:** Oil and gas industry professionals, specifically those engaged in drilling operations and planning. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] [HIGH IMPACT] Audit codebase for modern iOS compatibility because the app has not been updated since 2017 → restore platform stability. — *The 2017-era codebase is a critical churn risk and technical debt barrier.* _(trade-off: deprioritize Pause all new feature development until the core build is stable on current iOS versions.)_ - [ ] [PIVOT] [HIGH IMPACT] Ship offline-first calculation engine because field sites lack reliable connectivity → increase utility in remote operations. — *Competitors like Sludge Dewatering Calculator are capturing market share by prioritizing offline-first engines.* _(trade-off: deprioritize Deprioritize the UI overhaul to focus engineering hours on the offline data engine.)_ ### Feature Gaps vs Competitors - Offline-first calculation engine (available in Sludge Dewatering Calculator but absent here) - Direct technical support integration (available in NEB Tools but absent here) ### Outlook: Declining The industrial utility market is shifting toward offline-first, high-connectivity tools that integrate technical support directly into the workflow. Drilling Engineering remains in maintenance mode, which leaves the user base exposed to migration as competitors with better mobile-first workflows gain traction. - 🔴 The lack of updates since 2017 signals a maintenance-mode posture, which invites disruption from modern, frequently updated industrial utility competitors. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 3.79/5 | | Total Reviews | 19 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Drilling Engineering** (this app) | 3.79/5 | N/A | PT.
