Methane is a powerful greenhouse gas (GHG). Over 20 years, it is 80 times more potent at warming than carbon dioxide, with onshore conventional wellsite production facilities being the source of more than 50% of petroleum methane emissions in the United States (US). An operator working in the gas condensate window of the Eagle Ford shale has been diligently looking for innovative transition technologies to help minimize methane emissions from wellsite sources. Other key sustainability attributes for the project were capex and opex savings while simplifying well-pad architecture.

The number of O&G wells at the end of their economic life continues to grow. Likewise, the costs continue to increase for their decommissioning & abandonment. Many benefits would accrue if these wells could be used as a source of geothermal energy, and interest is growing in the feasibility of re-purposing these wells to geothermal. A major consideration in new geothermal projects is a huge up-front capex requirements. In general, a quarter of the costs go towards drilling new wells and one-third towards completions. Thus re-purposing these wells could result in significant cost savings. However, many other factors must be considered, such as local energy demand, potential market, existing infrastructure, and technical challenges. A conversion strategy for the existing wells is discussed in terms of the wellbore integrity requirements and steps to ensure hydrocarbon containment during the heat extraction process. Potential well-integrity challenges in the inspection and preparation of these wells will be discussed in this presentation.

The energy industry faces many challenges. Among them are how to increase hydrocarbon production from maturing assets with constrained access to capit

This presentation presents a new approach to lifting heavy/viscous oil with a Pump design that will allow Operators to increase overall field production with reduced power consumption.

This webinar will provide an overview and benefits of key building blocks available to unlock stranded reserves by using long distance subsea tiebacks.

This webinar includes recently completed EOR projects, which attempts to bridge this gap utilizing the sustainable Organic Oil Recovery technology. The reservoir screening, project planning, execution protocols, and results are discussed, as well as results from the North Sea and South Oman.

This webinar introduces the concept of Operations Readiness & Assurance (OR&A) to those with some involvement in major energy projects. It identifies the current issues experienced by industrial megaprojects and explains how these may be resolved with a robust OR&A process and the appropriate tools, touching on the experience of a number of such projects and the reasons for their varying degree of success in deploying OR&A.

Digital Twin development for a Greenfield facility starts from the design and engineering phase. It is developed based on staged execution as the 3D engineering model of a plant is developed. Besides 3D, it has 4D/5D BIM capability which has cost as well as schedule dimensions also to control the project more effectively and efficiently and improve the project NPV. Digital Twin and data centric approach brings all the documents and data of the project phase at a centralized place.

One idea: Our industry is in the new era of greater competition and must become more efficient to continue to prosper. Only about 15 years ago "peak oil" theories were quite popular and accepted by the general public. Another school of thought, based on the concept of resource triangle, stated that as technology develops and as prices increase, vast amounts of hydrocarbon resources will become commercial. Oil and gas prices did increase and this led to the unconventional oil and gas revolution. Recent analysis of resource potential based on technical data collected for North American basins (S.A.Holditch et al) showed that we may think of hydrocarbon resources as being essentially infinite for practical purposes. However the cost of the resource development, as expressed by the production activation index (the CapEx required to create production stream of 1 stb/day) increased over the decade from about 1000-10,000 USD/bopd range for conventional oil, up to 15,000 USD /bopd, and more in some cases. Maintaining production levels with unconventional resources requires continuous drilling. The rapid rate of decline of unconventional wells translates to roughly a three-fold increase in the cost of generating a unit of energy compared to conventional wells. At this order of magnitude of energy cost, other sources of energy and combinations of technologies become competitive with conventional fossil fuel based energy and transportation. 3/4 of all the oil that we produce is used for 3 purposes: ground transportation, heating and electricity generation, and jet fuel. In this lecture we will discuss competitive technologies, their technical limitations, their progress in application and market penetration trends. These competitive technologies are solar power, electric automobiles, and magnetic levitation trains. The high energy density of gasoline made conventional internal combustion engine cars prevalent at the turn of the 20th century. But today, the higher energy efficiency of electric cars and improvements in battery technology are making electric vehicles competitive. We review how the future may look like and how our industry may adapt and change. As the transition starts there will probably be long term demand destruction trend in OECD countries. It is likely that the industry will experience significant downward oil price pressure as alternative technologies become more competitive. We need to train young engineers in energy engineering rather than just petroleum engineering. Presented by Dr. Iskander Diyashev

In most conventional reservoirs, less than 50% of recoverable hydrocarbons are delivered in the initial development phase. As capex budgets tighten, operators continue to explore means of maximizing production from their existing well assets. Current production and projected opex vs. capex trends show an increasing demand for maximizing production from existing and maturing wells. These macro drivers have steered development efforts in key segments, including acid stimulation and water and gas conformance. Join our Schlumberger experts as they discuss how you can extend the life of your maturing assets with a focus on stimulation and conformance. A cursory look into the challenges and design workflows, coupled with cost-efficient, sustainable, and low-risk innovative solutions will be reviewed in this very insightful seminar.
