... shale oil EOR method is proposed that utilizes a triplex pump to inject a solvent liquid into the shale oil reservoir, and an efficient method to recover the injectant at the surface, for storage and reinjection. The process is designed and integrated during operation using compositional reservoir...

... introduce the consecutive DFITs (Diagnostic Fracture Injection Test) approach. Closure pressure is evaluated by falloff pressure analysis after a micro fracturing injection operation, and pore pressure could also be evaluated if the falloff period is long enough. This micro fracturing operation is generally...

... Abstract Drilling for hydrocarbons in extremely high reservoir pressures and temperatures is one of the most challenging combinations in drilling operations, especially related to drilling fluids. A combination of excellent teamwork and fluids technology proved to be the formula...

... Abstract Most coal seam gas (CSG) wells in Queensland require some form of artificial lift to remove water and initiate the liberation of gas adsorbed onto the coal matrix. Careful management of the flowing bottom hole pressure (FBHP) is a standard practice in CSG operations. Inducing rapid...

..., a 300% production increment was achieved by the two-stage CO 2 foam fracturing treatment in trial well D in the S1 and H8 formations. Further optimization of cost and operational efficiency will allow CO 2 fracturing technology to significantly increase production and nearly double the gas initially...

...: this means using data both to mitigate risks, to increase operational efficiency, by improving processes, and to create new business models. We propose a new approach where expert geologists collaborate with data scientists to develop a tool based on Machine Learning (ML) and Artificial Intelligence (AI...

... Recovery (EUR) from wells. The lower injection rates and pressures, in addition to the cyclic injection approach, mitigate the risk of induced seismicity and inter-well ‘frac hits’. During its operation, freshwater and chemicals are not used, reducing the environmental impact of the S&E process. Also...

... failure date. These findings enable gas operators to arrange the maintenance and replacement of the pumps, reducing the downtime and thereby increasing the production of gas wells. artificial lift system complex reservoir machine learning upstream oil & gas progressing cavity pump early...

... With today's current technologies it is possible to answer the question, "What is my most profitable mode of operation for the next few hours, for the rest of today, tomorrow and beyond?" With ‘lower for longer’ oil prices the need for enterprise wide optimization in the upstream...

... earthquake being in 2015 (Eidsvold, M=5.2 main-shock). Aftershocks of this event continued to be recorded some four years subsequent. Since 1937, a growing number of entities have operated seismic networks within the State, for varying purposes and with equipment of varying instrumental design...

... wells producibility and low MTBF can open the doors to multi-well pads and bring efficiency in operations while reducing the surface footprint of CSG (Coal Seam Gas) operations (by mimicking vertical wells spacing through drilling deviated wells from a multi well pad). This paper focusses...

... of Vaca Muerta production is vital to the nation's economy. International investment experts point to the Vaca Muerta as having the potential to "revolutionize Argentina's debt dynamics, balance of payments and fiscal performance". 1 Mander This study chronicles one operator's development...

... production increase compared to offset wells. Implementation of the recommended measures, including usage of low sulfate-containing water wells, addition of approved scale inhibitors, monitoring of water quality, etc., have showed no scales formation during well intervention and production operations, which...

... Abstract In early 2016 the Oklahoma Corporation Commission (OCC), the state regulator for oil and gas wells in Oklahoma, observed anomalous seismicity near oil and gas wells with active hydraulic fracturing operations. In response to well completion-associated seismicity, the OCC in the summer...
