This article highlights interesting applications of machine learning in the oil and gas industry in drilling, formation evaluation, and reservoir engineering. Each project uses a data-driven model to solve a previously complex problem using machine learning to augment an existing solution. Graham Hack shares his experience working for a large and a small E&P company and discusses how the role of young professionals can differ in these companies. This article presents three important R&D realms that demonstrate good collaborative efforts between independents and academic research institutions. Three women working in R&D offer perspectives on their work, why they joined that branch of the industry, what projects they work on, and what keeps them challenged.
Several oil fields are currently under one or more of Enhanced Oil Recovery (EOR) processes Worldwide. Main groups of EOR processes include chemical, solvent (gas), and thermal EOR plus other processes. The goal of this course is to provide attendants with solid understanding of different aspects, types, and applications of current and advanced Enhanced oil Recovery (EOR) processes. The main oil recovery categories include primary, secondary, and enhanced oil recovery. After the reservoir is depleted, secondary and enhanced oil recovery methods will be introduced targeting the residual oil saturation of this field.
Cenovus Energy announced that it reached 1 billion bbl of cumulative production from its oil sands facilities in northern Alberta, becoming the first company to reach this milestone using SAGD technology. Steam-assisted gravity drainage (SAGD) is a prime example of how structured research and development (R&D) has led to the commercial implementation of technology, helping unlock hydrocarbon resources to fulfill society’s energy demands.
The addition of a hydrocarbon condensate to steam operations in heavy-oil and bitumen reservoirs has emerged as a potential technology to improve not only oil recovery but also energy efficiency. Thermal steam stimulation is considered the most effective of current methods for heavy-oil production. However, the method has problems with low coverage by steam injection and decreased efficiency.
A horizontal-steam-injection pilot project has been under way for the last 4 years in the Kern River heavy-oil field in the southern San Joaquin Valley of California. This paper presents an investigation into the effect of catalytic nanoparticles on the efficiency of recovery from continuous steam injection. The operator has initiated a cyclic-steam-stimulation project in the Opal A diatomite of the Sisquoc formation on the Careaga lease in the Orcutt oil field in Santa Barbara County, California.
As technical people working in the Montney, most of our focus has been on drilling performance, completion improvements, and overall cost reduction in all aspects. But what other trends are occurring that need to be on our radar screens? Our opening panel will be bringing many perspectives, including the funding side, the importance of ESG, consulting trends and an overview of the North American market as a whole. Exploitation design is a product of interlinked decisions on well design, completion design, well spacing and cost structure. How are Montney operators pursuing the right balance of resource recovery and profitability?
Its reward for years of struggling to adapt to low prices and weak demand for its oil and gas has been an epic crash. Canadians selling change say it is time to consider possibilities that seemed inconceivable in the past. So many unprecedented changes have occurred in the Canadian oil business that it is impossible to compare the current downturn to anything seen before. Steam-assisted gravity drainage (SAGD) performance in bitumen-recovery projects in Alberta is affected by geological deposits, reservoir quality, and operational experience. Although polymer flooding has become a promising enhanced oil recovery (EOR) technique, no field tests have been performed to date in Alaska’s underdeveloped heavy-oil reservoirs.
The complete paper describes piloting the collection and analysis of distributed temperature and acoustic sensing (DTS and DAS, respectively) data to characterize flow-control-device (FCD) performance and help improve understanding of steam-assisted gravity drainage (SAGD) inflow distribution. A company is selling a new well testing tool designed to be a cheaper, simpler way to do fiber optic sensing, and then it fades away. With the availability of more-complex smart-well instrumentation, immediate evaluation of the well response is possible as changes in the reservoir or well occur. Mechanical-diversion techniques can ensure acid injection into the various intervals of naturally fractured reservoirs. This paper presents results from full-scale testing of a flexible riser equipped with embedded sensors for distributed-temperature sensing (DTS).

In 2014, a research and development (R&D) project was initiated to increase the life expectancy of Gulf of Mexico (GOM) Miocene and Lower Tertiary water-injection (WI) wells, several of which had suffered a severe loss of injectivity within only a few years of completion.
