For thin-oil-rim reservoirs, well placement, well type, well path, and the completion methods must be evaluated with close integration of key reservoir and production-engineering considerations. For thin-oil-rim reservoirs, well placement, type and path, and well-completion methods, should be evaluated with close integration of key reservoir- and production-engineering considerations.
This paper outlines the value of 4D for reducing uncertainty in the range of history-matched models and improving the production forecast. This paper describes interpretation results of a 4D seismic-monitoring program in a challenging Middle East carbonate reservoir. Integrated surveillance is critical for understanding reservoir dynamics and improving field management. A key component of the surveillance is areal monitoring of subsurface changes by use of time-lapse geophysical surveys such as 4D seismic. In this paper, the authors propose a new method for time-lapse-seismic surveys focused on water-injector wells.
Devon exits the asset that served as the company’s cornerstone for almost two decades and is known to the world as the birthplace of the shale revolution. Matrix acidizing is commonly used as a preflush to the hydraulic-fracturing stimulation of shale formations. The process dissolves sediments and mud solids that inhibit the permeability of the rock, enlarging the natural pores of the reservoir and stimulating flow of hydrocarbons.
In view of the continuing COVID-19 pandemic, EAGE is announcing today the postponement of the 82nd EAGE Annual Conference and Exhibition scheduled for 8-11 June in Amsterdam. We are now going to hold the event at the same venue (Rai Exhibition Centre, Amsterdam) in the week of 6 December 2020. We are confident that intending visitors, exhibitors and sponsors will understand the reasons for this decision and sincerely hope all those involved will be able to join us in December. For more information please visit the EAGE website. SPE EUROPEC 2020 at the 82nd EAGE Conference & Exhibition is the largest and most comprehensive multi-disciplinary geoscience event in the world.
So many unprecedented changes have occurred in the Canadian oil business that it is impossible to compare the current downturn to anything seen before. Most of ConocoPhillips’ oil and gas production by the end of the next decade will come from its unconventional operations. But, for the near-term, the Houston independent will rely on conventional assets as it seeks to keep spending in check, decline rates low, and cash flow on the rise. Previous studies demonstrate that Montney rock samples present a dual-wettability pore network. Recovery of the oil retained in the small hydrophobic pores is uniquely challenging.
In response to increasing demand for remote offshore services, Fugro has completed the Middle East’s first fully autonomous geophysical shallow-water route survey. Launched in collaboration with industry leaders and academia, the Microsoft Energy Core aims to accelerate digital transformation, build coalitions for responsible innovation, deliver skilling initiatives, and address sustainability and societal challenges. ConocoPhillips has deployed a low-code platform called Mendix to cut costs and increase efficiency, making it the first major oil and gas producer to use such technology across the company. A recent test proved the feasibility of using LiDAR on remote-controlled drones to create 3D maps of the inside of tanks, increasing the safety and efficiency of inspections. Three-dimensional seismic technology helped unlock more subsurface secrets for oil and gas operators.

A new tool developed by Kosmos Energy is allowing the exploration and production company to keep better track of the effect it is having on the environment. The new software enables high-resolution, real-time fracture-stage data to be shown on top of multiple previous stages to visualize optimized performance or to be tracked against an ideal preset stage. The Open Group OSDU Forum aims to create a standard data platform on which members work collaboratively to enable secure, reliable, global access to all subsurface and well data.
Africa (Sub-Sahara) An initial drillstem test on the Mzia-2 well in Block 1 flowed at a maximum rate of 57 million ft3 of gas per day, increasing the estimated recoverable resources from the field to 4.5 trillion ft3. This is the first test carried out on a Cretaceous discovery in deepwater offshore Tanzania. BG (60%) is the operator in partnership with Ophir Energy (40%). Asia Pacific Production has begun from the Wei Zhou 6-12 oil field in the Beibu Gulf basin in the north part of the South China Sea. The project has 10 producing wells drilled at an average water depth of 29.2 m. CNOOC has a 51% operating interest in partnership with Roc Oil, Horizon Oil, and Oil Australia. Salamander Energy signed production-sharing contracts for the Northeast Bangkanai and West Bangkanai license areas, onshore central Kalimantan in Indonesia. Each area covers approximately 2,214 sq miles.
Africa (Sub-Sahara) Namibia's Ministry of Mines and Energy approved a 1-year extension to its offshore license covering Block 2714A to Chariot Oil & Gas. The extension will allow for the completion of its analysis of the drilling results of the Kabeljou-1 exploration well. Petrobras (30%) is the operator in partnership with Chariot (25%) and BP (45). Asia Pacific The Basset West-1 well encountered 25 ft of gas pay in Jurassic sandstones on the Browse basin offshore Western Australia. The well was drilled to a total depth of 5240 m. Total E&P Australia (50%) is the operator in partnership with Santos (30%) and Murphy Oil (20%). Australia's government awarded 13 new offshore petroleum exploration permits after receiving 23 bids for 15 blocks. A total of USD 172 million will be spent exploring the areas, which are located offshore Western Australia and Tasmania, over the initial 3 years of the permit terms.
