Devon Energy operations interviews reflect the drilling, completions, production, and field operations execution discipline of one of the largest U.S. independent oil and gas producers, where operations means running a multi-basin horizontal drilling and completions program across the Delaware Basin, Eagle Ford, Anadarko Basin, Powder River Basin, and Williston Basin while simultaneously managing the production operations for Devon's large existing well count with the efficiency and cost discipline that Devon's free cash flow and fixed-plus-variable dividend model demands: managing the horizontal drilling program execution that keeps Devon's rigs operating at planned drilling days per well, lateral footage per day, and total well cost targets in Devon's core operating areas where a 10% improvement in drilling efficiency across a multi-rig program can translate to millions of dollars of capital savings and additional well locations within Devon's fixed annual capital budget, executing the hydraulic fracturing and completions program where Devon's completions engineers are continuously optimizing proppant loading, cluster spacing, stage design, and fluid volumes to improve 30-day, 90-day, and 180-day initial production rates in Devon's different formation targets, and managing the production operations for Devon's large operated well count including artificial lift optimization, facility maintenance, water disposal, and gas gathering system management that collectively determine Devon's base production volumes and lifting costs across its multi-basin operating footprint. Operations at Devon runs in a returns-focused, capital-disciplined E&P culture where every drilling day saved, every dollar of LOE reduced, and every BOE of production optimization represents direct improvement in Devon's free cash flow and shareholder returns.

What interviewers actually evaluate

Horizontal Drilling Execution, Completions Optimization & Production Operations Efficiency

Devon Energy operations interviews center on the ability to execute Devon's horizontal drilling and completions program at planned cost and efficiency targets, optimize well productivity through completions design and production management, and manage the production operations for Devon's large multi-basin well count with the lifting cost discipline that Devon's free cash flow model requires. Strong candidates demonstrate upstream E&P drilling, completions, or production operations experience, bring specific drilling efficiency improvement, completions optimization, and production uplift or LOE reduction outcome metrics, and show understanding of how E&P field operations management differs from refining, midstream, or industrial operations in terms of subsurface uncertainty, horizontal well production management, and the capital allocation discipline of a returns-focused shale E&P company.

Horizontal drilling program management including rig contract and vendor management, drilling day performance tracking, wellbore trajectory management, and total well cost control for Devon's multi-rig drilling program across its Delaware Basin, Eagle Ford, Anadarko Basin, Powder River Basin, and Williston Basin operating areas, hydraulic fracturing and completions execution including frac fleet scheduling, proppant and fluid supply chain management, completion design implementation, and 24-hour completions operations management for Devon's high-intensity multi-stage fracturing program, production operations management including artificial lift program management (ESP, rod pump, gas lift), production facility operations, water disposal and injection system management, and gas gathering and compression system oversight for Devon's operated well base, well performance monitoring and production optimization including production surveillance, decline curve analysis, production enhancement candidate identification, and workover program management for Devon's large operated well count, health, safety, and environment (HSE) management for Devon's field operations including incident prevention, OSHA compliance, EPA environmental compliance, and contractor safety management for Devon's operated drilling, completions, and production facilities, cost management and LOE efficiency including production cost tracking, vendor contract management, and operational efficiency improvement initiatives that reduce Devon's lifting cost per BOE across its multi-basin operations, and new well facility planning and surface infrastructure coordination including production facility design, saltwater disposal system planning, and gas gathering connection coordination for Devon's new well programs in each operating area

What gets scored in every session

Specific, sentence-level feedback.

Dimension What it measures How to answer
Process Clarity Can you describe an E&P operations process clearly – horizontal drilling sequence, hydraulic fracturing stage design, artificial lift optimization workflow – including inputs, steps, outputs, and failure points? We score the technical clarity of your field operations process description. E&P operations stages named, rig and frac crew coordination, subsurface and surface failure mode awareness
Efficiency Impact What improved and by how much? We flag stories without a quantified before/after – drilling days per well reduction, total well cost improvement, completions design IP30 improvement, LOE per BOE reduction. Days per well %, $/lateral foot, BOE/day uplift, LOE $/BOE reduction, production optimization %
Execution Ownership Did you design and implement the E&P operations change, or observe it? We detect whether you were the actor or the narrator in your own Devon operations story. Personal action verbs, drilling program decision ownership, completions design accountability
STAR Balance E&P operations stories often have strong Situations and weak Results. We flag imbalanced structures and help you invest more in Action and Result with specific well economics and production metrics. STAR proportion, well cost or production performance specificity

How a session works

Step 1: Get your Devon Energy Operations question

You are assigned questions based on where Devon Energy operations candidates typically struggle most, which is drilling program efficiency management and completions optimization with specific well cost, drilling efficiency, and production performance outcome metrics. Each session starts fresh with a new question targeting a different evaluation dimension.

Step 2: Answer by voice

Speak your answer as you would in a real interview. The AI listens for STAR structure, horizontal drilling and completions operations vocabulary, and whether you connect operational decisions to drilling efficiency outcomes, completions performance, production optimization, and Devon's well cost and free cash flow results.

Step 3: Get scored dimension by dimension

Instant scores across all four rubric dimensions. Each gets a score, a flagged weakness, and a specific sentence-level fix, not "be more specific" but which sentence to rewrite and why.

Step 4: Re-answer and track improvement

Revise based on feedback and answer again. See the before/after score change across Process Clarity, Efficiency Impact, Execution Ownership, and STAR Balance. Your weakness profile updates across sessions so practice becomes more targeted.

Frequently Asked Questions

What questions does Devon Energy ask in Operations interviews?

Expect behavioral and situational questions focused on drilling execution, completions optimization, and production operations efficiency. Common prompts include how you identified and implemented a drilling efficiency improvement that reduced Devon's average days per well in the Delaware Basin by improving the directional drilling assembly selection, drilling fluid program, and bit performance across Devon's operated rig fleet, how you analyzed the completion design data from Devon's drilled Delaware Basin Wolfcamp wells and identified the proppant loading and cluster spacing parameters that were most correlated with 90-day initial production rates, leading to a refined completion design recommendation for Devon's next program wells, and how you developed and executed the production optimization program that identified the highest-value artificial lift adjustment and workover candidates in Devon's Anadarko Basin well population and prioritized them for production enhancement intervention. Prepare one failure story involving a Devon drilling, completions, or production operations decision that did not deliver the expected well cost, well performance, or production efficiency outcome.

How hard is Devon Energy's Operations interview?

The difficulty is horizontal drilling and shale completions complexity combined with Devon's capital discipline and free cash flow focus. Candidates who come from conventional or non-E&P operations backgrounds struggle when interviewers press on how horizontal drilling efficiency is managed – why "days per well" is the primary drilling efficiency metric, what the major non-productive time categories are (stuck pipe, wellbore stability problems, equipment failure, weather), how Devon's drilling team uses offset well data and real-time monitoring to minimize NPT and optimize rate of penetration in its target formations, how hydraulic fracturing completions design works in Devon's major shale plays – what the difference is between plug-and-perf and sliding sleeve completions, why cluster spacing and perforation density affect fracture complexity and proppant distribution, how Devon tests different completion designs by running A/B tests across pad wells and analyzing 30-day, 90-day, and 180-day production results to identify which completion parameters improve EUR, how artificial lift selection and optimization works for Devon's horizontal wells – why horizontal shale wells go on artificial lift within months of first production as reservoir pressure declines, what the selection criteria are for ESP versus rod pump versus gas lift in Devon's different operating environments, and how production optimization teams detect artificial lift performance degradation through downhole gauges, pump cards, and production trend analysis before a well goes offline, or how water management works in Devon's E&P operations – why horizontal shale wells produce large volumes of produced water that must be disposed of through injection wells, how Devon's water disposal system capacity affects its ability to maintain production rates, and what the regulatory requirements are for produced water injection under the UIC program in Devon's operating states. Candidates who understand horizontal E&P operations advance.

What does Operations at Devon Energy involve?

Devon Energy operations covers horizontal drilling program management and rig performance optimization; hydraulic fracturing and completions execution and design optimization; production operations management including artificial lift, facilities, and water disposal; well performance monitoring and production optimization; HSE and environmental compliance for E&P field operations; production cost and LOE management; new well facility planning and surface infrastructure; drilling vendor and frac fleet contractor management; workover program planning and execution; drilling and completions technology evaluation and implementation; and Devon's multi-basin field operations coordination across the Delaware Basin, Eagle Ford, Anadarko Basin, Powder River Basin, and Williston Basin.

How do I prepare for Devon Energy's Operations interview?

Study horizontal drilling fundamentals: understand how horizontal well drilling works, what the major drilling efficiency metrics are (days per well, lateral footage per day, cost per lateral foot), what the major non-productive time categories are, and how drilling programs are optimized through bit selection, drilling fluid design, and directional assembly management. Understand hydraulic fracturing completions: how multi-stage hydraulic fracturing works in horizontal shale wells, what the major completion design variables are (cluster spacing, proppant per foot, fluid volume per stage), and how completion design affects initial production rates and EUR. Study artificial lift: how ESP, rod pump, and gas lift systems work, what the selection criteria are for each lift type, and how artificial lift performance is monitored and optimized. Understand water management: how produced water disposal through injection wells works, what the UIC program requires, and how water disposal capacity affects E&P production operations. Study Devon's operating areas: the major formations (Delaware Basin Wolfcamp/Bone Spring, Eagle Ford, STACK/SCOOP, PRB, Williston) and how formation characteristics affect drilling and completions design. Study HSE for upstream E&P: OSHA general industry and construction standards applicable to drilling and production, EPA Clean Air Act and Clean Water Act requirements for E&P facilities, and Devon's contractor safety management program. Prepare operations examples with drilling efficiency, well cost, completions performance, production uplift, and LOE outcome metrics.

How do I handle questions about a drilling efficiency challenge?

Describe the drilling operations situation – what the rig program was (number of rigs, formation target, lateral length target), what the efficiency metric shortfall was (days per well above plan, cost per lateral foot above target, non-productive time rate elevated), and what the well economics impact was relative to Devon's capital budget – how you diagnosed the root cause of the efficiency problem (bit selection mismatch for formation hardness, directional assembly performance, drilling fluid incompatibility with formation chemistry, surface equipment bottleneck) – how you designed and implemented the operational change program (bit program update, directional assembly change, drilling parameter adjustment, surface equipment upgrade) – how you measured the efficiency improvement in real time and communicated the results to Devon's drilling management and finance teams – and what the days per well improvement, total well cost reduction, and capital program financial impact was. Show that you understood both the technical drilling optimization and the financial well economics implications of the efficiency improvement rather than treating E&P drilling operations as a purely technical execution challenge. Interviewers want to see Devon Energy drilling operations judgment that connects field execution to well cost and free cash flow outcomes.
