Energy

We source, structure and develop high-quality opportunities across the upstream sector

Purestone focuses on energy assets where specialist insight and disciplined execution can unlock long-term value. In East Texas, we work with experienced local operators to assemble mineral interests and build coherent natural gas development portfolios.

A Focused East Texas Natural Gas Strategy

Unlocking High-Value Natural Gas Potential

Purestone is pursuing a focused natural gas strategy in Harrison and Panola Counties in East Texas, where the Haynesville Shale and Cotton Valley formations overlap. The region combines established production, extensive infrastructure and proximity to Gulf Coast LNG export terminals. By targeting overlooked acreage, we seek to assemble portfolios with the potential to support meaningful upstream development.

Guided by Deep Regional Understanding

Local Knowledge as the Key to Upstream Access

Fragmented mineral ownership and complex land negotiations make regional expertise essential. Purestone brings investment structuring, investor relationships and oversight, while Texstone Resources LLC contributes lease acquisition experience, landowner relationships and local operating knowledge. Together, we seek to identify off-market mineral interests, navigate historical ownership patterns and assemble coherent acreage positions.

Investment approach

From acreage assembly to development

Our approach combines investment structuring with local land expertise and phased development planning. Each stage is intended to build on the underlying acreage position, from securing mineral leases to establishing production and assessing potential routes to monetisation.

01/Assemble

Secure leases and form blocks

Identify mineral interests, negotiate leases and bring fragmented acreage together into coherent production blocks. Trade acreage with other operators where beneficial.

02 / DEVELOP

Establish production and reserves

Plan initial wells to hold leases, establish production and improve understanding of the remaining development potential. Reserve-based financing may support further activity, subject to lender agreement.

03 / MONETISE

Assess strategic routes to value

Evaluate sales of producing wells and undrilled locations to larger operators, block by block, or continued development. Timing and outcomes depend on asset performance and market conditions.

Connecting supply with demand

From Texas to global markets

Natural gas is extracted in Texas, transported to the Gulf Coast and cooled into liquefied natural gas (LNG) for shipment to markets in Europe and Asia.
