Occidental Petroleum Internship 2027–2028: Programs, Deadlines & How to Apply

Last updated: August 2026

Oxy chemical-engineering interns have reported earning $40.00 an hour, roughly $6,933 a month, with corporate housing provided (Levels.fyi, Gregory, TX, Summer 2024). And Occidental treats interns "much like newly hired employees," with the 10-to-12-week summer built to "assess your potential long-term career fit" for a full-time offer. At one of the largest oil and gas producers in the United States, the internship is a genuine pipeline into a Permian Basin engineering career, plus a fast-emerging low-carbon arm building the world's largest direct-air-capture plant. Here is everything you need to know to land a seat for summer 2027.

Quick Facts

Occidental Petroleum runs a structured 10-to-12-week paid summer internship across petroleum, chemical, mechanical, and geoscience disciplines, plus emerging low-carbon R&D. A verified data point puts chemical-engineering interns at $40/hour with corporate housing, the GPA floor is 3.0, roles require U.S. work authorization with no visa sponsorship, and applications for summer 2027 are expected to open around fall 2026 on a rolling basis, so apply early.

Externships are short, remote projects where you finish real work for a real company. The Amazon Fulfillment Ops & People Analytics Externship and the Hydroficient IoT Cyber Defense Externship build the operations-analytics and field-systems evidence that Oxy's engineering and HSE interviews reward.

What Is an Occidental Petroleum Internship?

Occidental Petroleum, known as Oxy and traded on the NYSE as OXY, is one of the largest oil and gas producers in the United States: a Fortune 500 company founded in 1920 and headquartered in Houston. Its internship is a structured 10-to-12-week paid summer program that Oxy explicitly designs as a full-time pipeline: interns are "treated much like newly hired employees," and the summer is built to "assess your potential long-term career fit." The business spans four segments: upstream Oil and Gas, Midstream and Marketing, OxyChem chemical manufacturing, and Oxy Low Carbon Ventures (OLCV), so an intern could sit on a Permian Basin reservoir-engineering team, an OxyChem plant, or OLCV's 1PointFive project, which Oxy describes as building STRATOS, the largest direct-air-capture facility in the world, designed to capture up to 500,000 metric tons of CO2 a year. That range makes Oxy unusual: a legacy energy producer with a fast-growing low-carbon and direct-lithium-extraction R&D arm, and internship seats across both.

When Do Occidental Petroleum Internship Applications Open for 2027–2028?

Oxy does not publish fixed internship application dates, so the timeline below is anchored to its fall campus-recruiting cadence and labeled expected wherever no official date exists. The pattern in oil and gas is consistent: summer reqs post in the fall, recruiters review on a rolling basis, and seats fill before any hard deadline. For the summer 2027 cycle, that means postings for summer 2027 are expected to open around fall 2026 (roughly September through November), with interviews and offers rolling through winter and early 2027, and the internship itself running from late May or June to August 2027. As of August 2026, Oxy's University Relations portal showed summer intern reqs off-cycle, so now is prep time.

Why You Must Apply the Week Applications Open

Oxy does not run a single hard deadline; it runs a rolling funnel, and that is exactly why timing decides outcomes. Third-party trackers describe Oxy intern reqs as opening and closing regularly and filling first-come with the explicit guidance to "apply early" (crackr.dev). Oxy's own postings confirm the mechanic: the new-grad R&D req states Oxy "anticipates that it will accept applications for this position for 14 days after the posting date, although it may extend that date depending on applicant flow." In practice, a req in your discipline can be reviewed and filled inside two weeks. The candidates who convert are the ones who have their Workday profile built, resume tailored to a specific track, and alerts set before fall 2026, so they apply the week a summer 2027 posting appears rather than the month after. Applying early also lands you in the interview queue sooner, and since offers extend as seats fill, an early panel is a real advantage.

Which Occidental Petroleum Internship Programs Should You Target?

Oxy runs one structured summer internship program with multiple discipline tracks rather than a set of separately branded programs. The five tracks below map to where interns actually land, from Permian Basin field engineering to OxyChem plants to the low-carbon R&D arm. Pick the one that matches your major and tailor your application to it.

See live reqs on the Workday University Relations portal. Engineering and geoscience seats are the deepest; low-carbon R&D roles skew toward graduate and PhD candidates, though broader OLCV functions have undergraduate seats. Note that field and plant roles carry real physical requirements: PPE including a respirator, lifting around 40 pounds, and climbing ladders and stairs.

What Are the Eligibility Requirements?

Oxy publishes eligibility on its engineering college-hire and new-grad job descriptions rather than a single intern posting. The core bar is consistent across the roles reviewed:

• Enrollment: Current undergraduate, typically a rising junior or senior, for summer internships; graduate and PhD students for R&D and low-carbon research tracks.

• Majors: Petroleum, Mechanical, Chemical, Petrochemical, and Electrical Engineering; Geophysics, Geology, and Petrophysics; plus limited seats in Finance/Accounting, HR, IT, Sales, Supply Chain, and Land Management.

• GPA: A minimum cumulative 3.0 on a 4.0 scale, stated on both the Engineering College Hire and R&D New Grad JDs. This is a hard floor.

• Work authorization: U.S. Citizen or U.S. Permanent Resident. The R&D New Grad JD states plainly that Oxy is "unable to sponsor employment visas." Assume no sponsorship for U.S. student internships.

• Field readiness (technical roles): ability to lift ~40 lbs, climb ladders and stairs, wear PPE including a respirator, respond to alarms, and possibly cover weekend or callout shifts.

Two Companies Named "Oxy": Don't Apply to the Wrong One

One trap trips up applicants every cycle: Occidental Petroleum (oxy.com) is a completely different organization from Occidental College in Los Angeles (oxy.edu, home of the "InternLA" program). If you are targeting the oil and gas internship, ignore oxy.edu and InternLA dates entirely. Beyond that, Oxy recruits nationally but names priority schools, and applying from one materially improves visibility: Colorado School of Mines, Texas A&M, Texas Tech, University of Houston, UT Austin, Oklahoma State, UT Permian Basin, Tuskegee University, Murray State, and Midland College. Finally, apply only through oxy.com/careers; Oxy repeatedly warns about recruitment fraud and never charges fees or requests bank or passport details early in the process.

What Skills Does Occidental Petroleum Look For, and How Do You Build Them?

Oxy's live intern postings were sparse in August 2026, so these skills come from three real Oxy job descriptions read in full: the OLCV/TerraLithium R&D New Grad JD (JR100734), the Engineering College Hire JD for the Oil and Gas business, and Oxy's official summer internships page. Two things dominate every JD: analytical, problem-solving thinking and genuine teamwork, both appearing in all three. From there the picture splits by track. Field and reservoir roles want production-engineering fundamentals: enhanced oil recovery, artificial lift, hydraulic fracturing. The low-carbon R&D roles want experimental and pilot-scale process work, Aspen Plus modeling, and statistical data analysis. And across the board Oxy weights communication (interns "present your work to Oxy leaders") and an HSE, safety-first mindset, which on a field site is non-negotiable.

Build These Skills Before You Apply

And every skill in that chart maps to a remote Externship where you finish a real project before an Oxy req opens.

How close is the overlap? The Amazon project builds the operations-and-people-analytics story a corporate or field-ops interviewer probes, the Hydroficient project puts you inside real IoT and field-systems work that maps to Oxy's HSE and automation focus, and the Wayfair project is build-and-ship engineering evidence that a technical panel wants to see.

What Is the Occidental Petroleum Application and Interview Process Like?

Oxy's intern process is recruiter-led and mostly behavioral, with foundational technical questions layered in. Community and third-party write-ups (devopsschool, Glassdoor, and first-hand Reddit accounts) describe a consistent flow:

1. Apply through the official portal. Go to oxy.com/careers, choose "Search Student Jobs," and filter the Workday University Relations portal by location and job family for a summer intern req in your discipline (expected to open ~fall 2026 for summer 2027).

2. Build your Workday profile and tailor your resume. Upload a CV tailored to the specific track and Oxy's EOR and low-carbon focus. Applications and offers only count through the company website, the sole valid channel.

3. Apply early. Reqs fill on a rolling basis, so submit in the first week a posting goes live rather than waiting for a deadline that may not exist.

4. Complete any assessment or video interview. Oxy's Workday flow can include assessments and recorded video interviews; specifics vary by role. OxyChem candidates have reported a timed three-part test: reading comprehension, math, and an "about you" section.

5. Recruiter and hiring-manager screens. A phone or video recruiter screen on interest and background, then a deeper phone interview with the hiring manager covering technical and experience topics.

6. Panel interview. A panel of the hiring manager, technical specialists, and HR, mixing behavioral and foundational technical questions, followed by time for you to ask questions. Intern panels lean behavioral over heavy technical grilling.

7. Attend campus events. Career fairs and info sessions at Oxy target schools boost visibility and can move your application forward.

Two things to note. First, this is a behavioral-first process: expect questions like "Tell me about yourself and your interest in Occidental Petroleum," "Describe a time you faced a challenge," and "How would you approach ensuring safety protocols on a rig," rather than a LeetCode gauntlet. Second, the whole thing runs on a rolling clock, from a few weeks to a couple of months depending on the role, so an early application generally means an earlier interview and a better shot before seats fill.

What Students on Reddit Say

Three community threads give a first-hand look at Oxy's intern hiring, all paraphrased.

How Do You Stand Out for an Oxy Internship?

Three moves, all doable before fall 2026. First, tailor to a single track. Oxy's tracks are distinct: Permian field engineering, OxyChem process work, geoscience, OLCV low-carbon R&D, and a resume aimed at one, using its language (EOR, artificial lift, direct air capture, Aspen Plus), reads far stronger than a generic engineering CV. Second, build proof of the analytical, HSE, and communication skills every Oxy JD names: a finished project you can walk a panel through beats a list of coursework, because Oxy interviews lean on "describe a time you..." storytelling. Third, work the target-school and rolling-timing advantage: get on Oxy's radar at a priority-school career fair, build your Workday profile early, and apply the week a summer 2027 req appears. On a rolling funnel, early and specific win.

What Other Companies Should You Consider?

Oxy competes for the same engineering and geoscience talent as the other U.S. energy majors and oilfield-services firms. If you are building an oil-and-gas internship list, these are the obvious neighbors to apply to alongside Oxy:

FAQ

Can I still apply for a summer 2026 Occidental Petroleum internship?

Almost certainly not. By August 2026 the summer 2026 program is already underway or complete, and Oxy's University Relations portal showed intern reqs off-cycle. Your realistic target is the summer 2027 cycle, with postings expected to open around fall 2026. Monitor oxy.com/careers and set Workday alerts now so you can apply the week a req in your discipline goes live.

Does Occidental Petroleum offer internships?

Yes. Oxy runs a structured 10-to-12-week paid summer internship program across engineering (petroleum, chemical, mechanical, electrical), geoscience, petrophysics, HSE, IT, finance, HR, sales, supply chain, and land management, plus co-op, new-grad, and low-carbon R&D pathways.

When do applications open for summer 2027?

No fixed date is published. Postings are expected to open in fall 2026 (roughly September through November) and fill on a rolling basis, so apply early. As of August 2026, summer intern reqs were off-cycle. Watch oxy.com/careers. This window is labeled expected, projected from Oxy's fall campus-recruiting cadence rather than an official prior-cycle date.

How much do Oxy interns get paid?

There is no official intern pay scale. A community-verified data point is $40.00 an hour (about $6,933 a month) for a chemical-engineering intern with corporate housing (Levels.fyi, Summer 2024, Gregory, TX). Glassdoor estimates cluster around $35 an hour across roles. Treat any much higher figures as small-sample estimates.

What GPA do I need?

A minimum cumulative 3.0 on a 4.0 scale, stated on Oxy's engineering job descriptions. It is a hard floor for the roles reviewed.

Does Oxy sponsor international students for internships?

For the roles reviewed, no. Oxy requires U.S. Citizen or Permanent Resident status and states it is unable to sponsor employment visas. Assume no sponsorship for U.S. student internships, and confirm per posting.

What is the Oxy interview like?

Typically two to four rounds: recruiter and hiring-manager phone screens, then a panel of the hiring manager, technical specialists, and HR mixing behavioral and foundational technical questions with time for your own. Some roles, such as OxyChem, add a timed reading, math, and "about you" test. Intern interviews lean behavioral over heavy technical.

Can an Oxy internship turn into a full-time job?

Yes. Oxy designs the internship to "assess your potential long-term career fit" and treats interns like new hires, and a former intern on Reddit reported receiving a full-time Oxy offer afterward. No official conversion rate is published, but the program is explicitly built as a full-time pipeline.

Oxy's summer 2027 reqs are not live yet, but the internship is a genuine pipeline into a Permian Basin engineering career and a fast-growing low-carbon arm. Spend the runway building proof: a remote Externship turns interest in energy and field engineering into a finished project you can walk an Oxy panel through the week a req opens.
