D3 Energy Takes Aim at Water Influx to Unlock South African Gas

Gas is there. It bubbles from deep within the earth. But at D3 Energy's Nooitgedacht Project in South Africa, that gas isn't flowing freely. Deeper water inflows have choked production, forcing the company to initiate urgent remedial work next week.

The Subterranean Snag

Downhole logging at D3 Energy Ltd (ASX:D3E, OTCQX:DNRGF) confirmed gas-bearing zones in both the NGT245 D and NGT245 E wells. This was the good news. The bad news? The same analysis pinpointed deeper water levels, actively restricting gas output.

Recent geophysical scans revealed a clear issue: water from deeper production zones had risen above the gas-bearing intervals in both wells. Reservoir pressure is extremely low. This elevated water level halts the gas. It simply can't move.

High-tech downhole cameras captured the problem. They identified the gas zones before the water rose, inhibiting flow. The video evidence showed gas bubbling through the water column, confirming its presence within the target areas.

Cementing the Path Forward

D3 Energy will isolate these problematic water-producing zones. Remedial cementing is the chosen method. Work is scheduled to begin next week across both wells. The goal is simple: restore gas flow to the levels seen during initial drilling operations.

Managing Director and CEO David Casey addressed the setback. "Logging has helped explain why gas flow subsided during completion operations," Casey stated. "Encouragingly, however, logging has confirmed that this is in large part due to water rising from a zone below to above the gas bearing zone."

"While it is anticipated that remedial work should resolve this, it is nonetheless incredibly encouraging that both wells intersected gas bearing zones in what is our first drilling operation at Nooitgedacht."

The NGT245 D and NGT245 E wells target faults and associated fractures within the Ventersdorp and Witwatersrand formations. This drilling campaign marks D3 Energy's first at Nooitgedacht. It aims to assess reservoir deliverability. It also gathers vital information on helium and methane concentrations.

Nooitgedacht falls within D3 Energy's wholly-owned ER315 permit in South Africa's Free State. It lies approximately 40 kilometres from the company's Production Right application area. Success here will provide additional insights into the broader potential of the ER315 acreage.

D3 Energy pushes ahead. They expect to resume gas production soon, turning a temporary obstruction into a deeper understanding of their valuable South African assets.

Search Resumes for Missing Boat with Eight Near Indonesia's Anak Krakatau Volcano

Search and rescue efforts resumed Wednesday for a boat carrying eight people, including five journalists, that went missing near Indonesia's Anak Krakatau volcano. The vessel lost contact shortly after departing on Monday, according to local media reports. The five journalists are Indonesian citizens and represent local and international media outlets, including the state news agency Antara and the Turkish state-run agency Anadolu. They were in the area to cover the volcano's recent eruption. A search operation initiated on Tuesday was temporarily suspended due to large waves and hazardous conditions. Authorities have not yet provided a clear explanation for the boat's disappearance. The National Search and Rescue Agency is leading the ongoing efforts. The eruption of Anak Krakatau has significantly disrupted air travel in the region. Tens of thousands of people have been stranded on the islands of Java and Sumatra since the weekend, and multiple airports have closed due...

Mexico Projects Up To 2.5% Economic Growth, Smaller Deficit in 2027 Budget Draft

MEXICO CITY – Mexico's finance ministry forecasts economic growth between 1.5% and 2.5% in 2027. The broader public sector deficit is projected to narrow to 3.9% of gross domestic product (GDP) that year, according to a draft budget proposal submitted to Congress on Tuesday. The budget document indicates a 2026 growth estimate of 1.0% to 2.0%. This is a decrease from an earlier projection of 1.8% to 2.8%. The projected 2027 public sector deficit of 3.9% of GDP compares to 4.1% estimated for 2026. Factors driving the 2027 economic outlook include strong domestic demand, higher household incomes, and less restrictive financial conditions. Investment linked to infrastructure projects and tax incentives under the "Plan Mexico" initiative are also expected to contribute. Additionally, export growth supported by North American trade integration is anticipated to provide further support. Total public debt, measured by the Historical Balance of Public Sector Borrowing Requi...

AI-Generated Video Falsely Depicts Anak Krakatau Eruption Amidst Real Volcanic Activity

An AI-generated video falsely purporting to show a dramatic eruption of Indonesia's Mount Anak Krakatau has widely circulated on social media, even as the volcano experienced genuine multiple eruptions in September 2026. Indonesian authorities have dismissed the clip as a "hoax." The real volcanic activity in September 2026 was significant, spewing lava and plumes of volcanic ash across parts of Indonesia, including Lampung province and Greater Jakarta. This led to the closure of Indonesia's main international airport, Soekarno-Hatta International Airport, and seven other airports, stranding more than 340,000 domestic and international passengers and resulting in hundreds of flight cancellations. The fabricated video, which first began circulating in November 2025, gained renewed traction with a TikTok post on September 5, 2026. This post included an Indonesian-language caption warning residents in Lampung province to wear masks due to ash movement from Anak Krakata...
