Integrated 3D petroleum system model for shale gas/oil reservoirs in the Beetaloo Sub-basin & SPE QLD AGM
Presenter: Dr Mohinudeen Faiz The presentation will summarise key uncertainties in deciphering the ~1.3 billion year old petroleum system of the Beetaloo Sub-basin and its impact on evaluating source-rock-reservoirs within the Velkerri and Kyalla formations. In particular, sediment provenance, thermal history, impact of maturation kinetics of cyanobacteria and gas adsorption properties on the distribution of hydrocarbon types, storage and flow behaviour will be discussed. Biography of Mohinudeen Faiz: Dr Mohinudeen Faiz is a petroleum geoscientist with ~30 years’ experience in operational and R&D projects. Currently he is a Principal Research Scientist at CSIRO Energy where he focuses on integrated petroleum systems analyses for conventional and unconventional reservoirs. Previously, as Origin…Find out more »
• The purpose of SPE QLD Special Interest Groups (SIGs) is to create a regular forum for learning, discussion and networking to all interested parties. We will focus on improved and cutting edge technological developments. Work-in-progress, new ideas, and interesting projects are sought. The topics will include case studies, ongoing research, and development. The group meetings will act as a network for members to communicate ideas and solutions to each other. The SIG meeting are open only to the SPE members or special guests and numbers are capped at 25pax.
• The format of this session will be based around an informal technical discussion. As such there will be no slide presentations provided and note taking is not permitted to preserve the confidentiality of participants and their respective organizations.

With the increasing volatility in the price of oil, even low-cost onshore wells can be economically marginal and not achieve target rates of return under certain oil price scenarios and P10 or even P50 production profile forecasts. If such market conditions persist, it will become increasingly important that all wells produce to their full potential and that a war be waged on skin and that drainage area be maximised. Where wells are fractured, maximising fracture conductivity and half-length will also be essential. It is the author’s belief that this macro-economic environment will drive an increase in pressure transient analysis (PTA) complemented by rate transient analysis (RTA) because, just as Lord kelvin stated in 1883, what we cannot measure, we cannot improve.
Traditionally PTA requires build-ups, which is costly, both in terms of intervention and deferred production. Fortunately, the population of permanent downhole gauges does not cease to increase and this presentation examines how downhole real time pressure and rate data enables PTA in drawdown. Such technology not only provides a source of low-cost transient data, but also the ability to obtain inflow characterisation (mobility, skin, fracture half-length and conductivity and boundary conditions)) within a few weeks of completing a well, thereby confirming the time value of information.
To illustrate the concepts, PTA and RTA results from a MFHW (Multi Fractured Horizontal Well) case study are reviewed. This is based on data taken from URTEC 2790 paper and is particularly interesting as it demonstrates how high-quality production data can resolve a large number of unknowns. Also the history matching of flowing pressure with an analytical model yielded excellent results despite many discreet changes in flow-rate, which further enhanced confidence in the inflow characterization. Therefore if PTA can be performed in drawdown on a MFHW in unconventional tight formations, it should be relatively easy to achieve on conventional vertical wells. This workflow was applied to over 38 wells in the Bakken to generate a correlation of PV (Pore Volume) and PI ( Productivity Index) as a function of completion and fracture design thereby providing quantifiable feedback on how to drill and complete “winning” wells in a particular geological environment.
As always, economic constraints often stimulate technological creativity, and the author predicts that it will not be long before PTA in drawdown is industrialised and applied to SRP and free flowing wells with the addition of a downhole tools such as a venturis. Can we conclude that, even in a low oil price environment, economic production is possible if production is optimised utilising the right instrumentation and interpretation techniques ?
Subsurface Analytics; Digital Transformation of Reservoir Management with Artificial Intelligence and Machine Learning
Shahab D. Mohaghegh - Distinguished Lecturer Abstract: Subsurface Analytics is an alternative to traditional reservoir modeling and res. management. Positively influencing subsurface related decision making is the most important contribution of any new technology. Subsurface Analytics is the application of Artificial Intelligence and Machine Learning (AI&ML) in Reservoir Engineering, Characterization, Modeling, and Management. Applicable to both conventional and unconventional plays, Subsurface Analytics goes far beyond the traditional statistical algorithms that use only production data and fail to take into consideration the important field measurements such as well trajectories, well logs, seismic, core data, PVT, well test, completion, and operational constraints. Subsurface Analytics is the manifestation of Digital Transformation in Reservoir…Find out more »
ABSTRACT: Our industry is facing mounting pressure from all sides to decarbonize. Regulations are getting tougher in response to public pressure and investors are pulling capital out of the oil and gas industry over concerns that assets may be left in the ground stranded. Natural gas has been touted as the transition fuel to net zero. However, because of the methane emitted in the production and distribution process, some believe that it is dirtier than coal and cannot play this role. We have to act now or our industry will be viewed adversely and collectively we will make poor energy decisions for our planet. Technology that is able to detect…Find out more »
