These programs have grown more important as capital costs climb and regulatory scrutiny tightens. Operators need predictable returns, and predictability starts with a plan. This article covers what drilling programs are, the main types you'll encounter, training paths for anyone entering the field, and how to evaluate one before committing capital.
TL;DR
- A drilling program locks in well objectives, technical approach, and budget before oil and gas work begins
- Structured programs cut operational risk, control costs, and raise well success rates
- Core types cover exploratory, development, and directional or horizontal drilling
- Training ranges from rig-floor certifications to engineering and geoscience degrees
- Pick the program that matches your goals, risk tolerance, and required expertise
What Is a Drilling Program?
A drilling program is a documented plan, part technical, part operational, part financial, that governs how a well or group of wells gets drilled and developed. Operators, engineers, and geologists use it to sequence activity, allocate capital, and manage risk across a project or an entire acreage position.
It works as both an operating plan and an investment document. A clear program answers:
- Where do we drill?
- In what order?
- With what budget?
- What happens if the geology surprises us?
Why Drilling Programs Matter in the Oil & Gas Industry
Well-structured drilling programs correlate directly with higher success rates, controlled costs, and production timelines that actually hold up. Without one, operators risk:
- Budget overruns
- Safety incidents
- Missed reserve targets
The historical data backs this up. Between 1946 and 1988, US wildcat exploration success rates fell from 19% to 14% as drilling activity declined, according to an Oil & Gas Journal analysis.
More recently, AAPG has noted that a truly exploratory offshore well is more likely to be dry than successful, with global offshore success rates hovering around 40%. Those odds make program quality one of the few levers operators fully control.
The takeaway: planning quality directly shapes outcomes. That is why experienced technical teams and third-party validation matter when evaluating a program.
Types of Drilling Programs
Drilling programs vary by project stage, geological risk, and well trajectory. Knowing the differences helps investors judge risk, capital exposure, and expected returns.
Exploratory Drilling Programs
Exploratory programs test unproven or partially proven acreage to confirm hydrocarbons exist at all. They lean heavily on seismic data and core samples before any capital gets committed.
- Risk level: Highest among common program categories
- Best suited for: Companies with strong geoscience teams chasing new reserve discovery
- Upside: Significant if new reserves are confirmed
- Downside: Highest dry-hole risk and largest capital exposure per well
Development Drilling Programs
Development programs target proven reserves in fields that are already established. They use existing well and reservoir data to plan infill or step-out wells, so geological uncertainty is much lower.
- Risk level: Lower than exploratory, since reservoir characteristics are known
- Best suited for: Investors and operators who want predictable cash flow and faster payback
- Upside: Higher well success rates and more reliable forecasting
- Downside: Less "home run" potential since reserves are already quantified
Directional and Horizontal Drilling Programs
Unlike exploratory and development categories, directional and horizontal programs describe well trajectory—not whether the acreage is proven. They use non-vertical wellbore paths to maximize reservoir contact, engineered around lateral length, formation targeting, and completion design.
Horizontal and directional wells now dominate US drilling. They made up 81% of all US well completions in 2021, and by December 2024, horizontal wells accounted for 94% of Lower 48 oil production and 92% of natural gas production, according to EIA data.
- Risk level: Distinguished by trajectory complexity, not exploration risk
- Best suited for: Unconventional plays like shale or tight formations
- Upside: Significantly higher per-well recovery in the right formation
- Downside: Higher drilling and completion costs, plus specialized crew requirements
One trade-off: horizontal wells typically decline faster after initial production than vertical wells, so stronger early recovery comes with a steeper production curve.
Training and Career Paths for Drilling Programs
People enter drilling programs from very different directions: rig-floor personnel, engineers, and geoscientists. Each path requires different training.
Vocational and certificate training
Community colleges offer fast-track programs for floorhands and roustabouts. Houston Community College’s Roustabout Drilling Technician program, for example, requires at least 192 contact hours covering:
- Equipment handling
- Safety practices
- Drilling operations
- IADC RigPass orientation
- An introduction to IADC WellSharp well-control training
Union and apprenticeship training
The International Union of Operating Engineers runs apprenticeships that combine paid field hours with classroom instruction. IUOE Local 800’s program, for example, spans three years and requires:
- 4,500 paid on-the-job hours
- At least 144 hours of related instruction each year
Specialized technical training
Petroleum engineers typically need a degree plus ongoing certification. SPE’s Petroleum Engineering Certification calls for:
- A relevant engineering degree
- Four years of experience
- 16 hours of professional development each year
Geoscientists follow a parallel track. AIPG’s Certified Professional Geologist credential requires a geology degree, 36 semester hours of geology coursework, and eight years of experience (less with an advanced degree).
Why experience matters more than credentials alone
Formal training gets someone onto a rig or into an engineering seat. Decades of prospect-selection judgment are what separate well-planned programs from higher-risk ones.
PetroVybe’s Chief Geophysicist, Michael Stamatedes, brings a 48-year track record from ExxonMobil, including a documented 75.2% career hit rate selecting profitable well locations—well above typical industry averages. That judgment feeds directly into decline-curve projections and well outcomes.
How to Evaluate a Drilling Program (For Professionals and Investors)
Evaluating a drilling program means looking past the well type to the team behind it. Ask these questions:
- How strong is the geological data? Proprietary seismic paired with production data from nearby wells tells you more than acreage size alone.
- What's the operator's track record? Years of experience matter, but so does a documented success rate in similar basins.
- Is there independent reserve validation? Third-party engineering reports should back up any reserve claims.
- How capital-efficient is the plan? Look at projected cost per well against forecasted returns.
For accredited investors specifically, companies like PetroVybe offer a useful case study in how program quality gets assessed. PetroVybe's development drilling program in Lavaca County, Texas is backed by a $48 million proved-reserves valuation (PV-09) from a licensed third-party engineering firm, along with proprietary seismic data and geoscience leadership with a multi-decade track record in prospect selection. The company's due-diligence approach includes comparing forecasted decline curves against the 10 nearest producing wells, a practical way to stress-test assumptions before capital moves.
None of this eliminates risk, but it does show whether projections rest on verified data or on hope. Ask for the third-party report before you ask about the returns.
