A Look At The Most Active Counties In The Permian Basin

The Permian Basin remains the most influential oil and natural gas producing region in the United States. Stretching across West Texas and southeastern New Mexico, it contains several productive formations, including the Wolfcamp, Spraberry, Bone Spring, and Delaware sands. Activity is distributed across a large area, but a relatively small group of counties consistently attracts the greatest concentration of drilling, permits, infrastructure investment, and mineral-rights transactions.

County-level analysis provides a useful way to understand this activity. Production totals show where hydrocarbons are flowing today, while permits, rig locations, lease offers, and pipeline projects can indicate where development may expand next. These signals are especially valuable for landowners, mineral buyers, operators, engineers, and real estate professionals evaluating a specific tract.

The busiest counties can change depending on the metric being measured. A county may lead in horizontal permits while another has more active rigs, larger oil output, or a greater number of proposed well pads. Reviewing several data layers together produces a more accurate picture of the basin’s development pattern.

Why County-Level Activity Matters

The Permian is not a single uniform play. Its geology, operating costs, mineral ownership patterns, water availability, takeaway capacity, and permitting requirements vary from county to county. The Midland Basin in Texas generally differs from the deeper and more structurally complex Delaware Basin, which extends through western Texas and southeastern New Mexico.

County boundaries also provide a practical framework for research. Public records, appraisal data, drilling permits, production filings, and transportation projects are often organized geographically. Investors can use a county screen to narrow a large basin into manageable targets before examining individual sections, leases, wells, or parcels.

Subsurface trends can cross county lines, so county activity should be treated as a starting point rather than a final valuation method. A promising county may contain mature producing areas, undeveloped acreage, infrastructure constraints, and competing operators all within a short distance.

Midland And Martin Counties

Midland County is one of the best-known centers of Permian development. It sits near the heart of the Midland Basin and has long benefited from extensive infrastructure, established service companies, and dense networks of producing wells. The county’s name is closely associated with the broader regional energy industry, and its urban and industrial growth reflects that role.

Martin County, immediately north of Midland County, is also a major hub for horizontal drilling. Operators have pursued multiple benches of the Spraberry and Wolfcamp formations, creating a dense pattern of permits, well pads, gathering systems, and surface-use agreements. The proximity of these counties means that projects frequently depend on shared roads, processing facilities, pipelines, and workforce networks.

For mineral-rights investors, activity in Midland and Martin can create both opportunity and complexity. Strong development potential may support higher lease values, but it can also mean crowded surface conditions, overlapping infrastructure corridors, and a greater need to verify title, pooling, depth severances, and existing burdens.

Reeves, Loving, And The Delaware Core

Reeves County is widely regarded as one of the most active counties in the Delaware Basin. It has attracted substantial horizontal drilling across formations such as the Wolfcamp and Bone Spring, along with extensive midstream construction. The county’s scale and strong production profile make it a central focus for operators and energy analysts.

Loving County, although much smaller in population and geographic footprint, has generated significant attention because of its high concentration of oil and gas development. Its location within the Delaware Basin places it near some of the region’s most productive acreage. High-value mineral transactions and intensive drilling activity can occur alongside major constraints involving roads, water, workforce availability, and pipeline capacity.

Nearby counties such as Ward, Winkler, and Culberson also contribute to the Delaware Basin’s overall activity. Their development levels vary by formation and operator strategy, but permit clusters and new gathering routes can reveal how the basin is expanding beyond its most established core. The Paradox Basin overview is useful background for comparing the Permian with another western shale region that has a different maturity and development profile.

New Mexico’s Lea And Eddy Counties

Lea and Eddy counties form the principal New Mexico portion of the Permian Basin. Lea County, in particular, is a major oil-producing jurisdiction with a large concentration of horizontal wells, drilling permits, processing facilities, and supporting businesses. Its border location makes regional infrastructure and operator acreage positions especially important.

Eddy County contains substantial Delaware Basin development as well. Operators may evaluate both counties together because geological trends, transportation systems, water logistics, and service markets extend across the state line. A lease or mineral interest near the boundary can be influenced by activity on either side, even when the regulatory records are maintained by different state agencies.

New Mexico acreage research requires attention to state-specific permitting, pooling, royalty, and surface-use rules. County-level maps can identify areas of interest, but a serious review should connect the map to well files, lease documents, ownership records, and the relevant state regulatory database.

How The Counties Compare

The following comparison focuses on common development characteristics rather than fixed rankings. Activity can shift as commodity prices, capital budgets, drilling technology, and takeaway conditions change.

These counties should not be viewed as interchangeable. Midland and Martin may offer a mature operating environment, while portions of Reeves, Loving, Lea, and Eddy can show more concentrated Delaware Basin growth. Upton and nearby counties may be especially relevant when tracking development corridors moving outward from established areas.

Reading Permits, Wells, And Infrastructure

A permit is an intention to drill, not proof that a well will be completed. Still, groups of permits can reveal an operator’s development plan, particularly when they align with existing pads, leases, surface access, and nearby gathering lines. Comparing permit dates and targets can help distinguish a temporary filing pattern from a sustained program.

Existing well locations are another important signal. Horizontal laterals often reveal how operators are testing spacing, landing zones, and stacked formations. Shale Navigator’s guide to estimating future well locations explains how permit clusters and established development patterns can support more informed location analysis.

Infrastructure adds the operational context. A new pipeline, compressor station, processing facility, or improved road may make additional drilling economically practical. Conversely, a county with abundant permits but limited takeaway capacity may experience delays between leasing, drilling, completion, and production.

Surface And Mineral Research By County

County-level activity affects surface owners and mineral-rights holders in different ways. A mineral owner may focus on lease bonuses, royalty provisions, depth rights, pooling language, and the likelihood of future wells. A surface owner may be more concerned with roads, well pads, water lines, electric facilities, pipeline routes, and restoration obligations.

Infrastructure corridors deserve careful review before a transaction or negotiation. A property can appear outside a current production area yet still be affected by planned gathering or transmission facilities. Property owners researching possible rights-of-way can use this resource on identifying pipeline easements as part of a broader document and map review.

Shale Navigator brings these research needs into a single mapping and reporting environment. Users can compare shale plays, drilling permits, lease offers, available mineral rights, pipelines, and property information, then move from a county-wide view to a specific parcel or development area. A free seven-day account provides a practical way to evaluate the platform’s data layers before choosing additional subscription access.

A Practical County Screening Method

A disciplined workflow can make county comparisons more useful. Begin by identifying the basin subsection and formations relevant to the property. Then review recent permits, producing wells, operator footprints, and nearby infrastructure. The goal is to establish whether activity is established, accelerating, shifting to a new formation, or simply reflecting older filings.

Next, compare the property with surrounding development. Look for laterals entering nearby sections, repeated permit filings by the same operator, new pad construction, and infrastructure that could support future drilling. Check whether mineral ownership, surface ownership, and lease status are divided among multiple parties, since those details can materially affect development timing and value.

Useful screening priorities include:

• Compare recent permits with completed and producing wells.
• Identify operators with repeated activity near the property.
• Review pipelines, roads, processing facilities, and water infrastructure.
• Check mineral ownership, depth severances, leases, and title burdens.
• Track changes over time instead of relying on a single map snapshot.

County research becomes most valuable when it supports a parcel-level decision. By combining geographic context with legal, geological, and operational records, users can better evaluate potential development, infrastructure exposure, and mineral-rights market activity.

The Permian’s leading counties will continue to evolve as operators refine completion designs, pursue additional benches, and respond to commodity markets.
