Driven by a recovery in well completions and increased proppant loading per well, the market for raw fracturing sand is expected to grow by more than 4% annually through 2021, an industry research study says. Crude oil production in the United States is expected to approach 10 million B/D in 2018 and surpass a previous high achieved in 1970, according to the latest US EIA forecast. A global energy model estimates the long-term energy mix, including solids, liquids, and gases, that will satisfy energy demand to the year 2040.
There is talk about digital oil fields and big data and some striking examples of their power. But in real oil fields, a lot of operators are still running fields with systems relying on big paper. At the SPE Hydraulic Fracturing Technology Conference, one of the most innovative ideas discussed was a liquid proppant designed to turn into strong spherical balls to keep a fracture open.
Hydraulic fracturing solutions use a gelling agent known as guar gum to transport proppant. Flowback water can have guar gum concentrations has high as 1% by volume creating treatment challenges prior to reuse or disposal. In this second article of a series covering water management in hydraulic fracturing (HF) in unconventional resources, the properties and characteristics of the flowback fluids are discussed, together with the general categories of technologies that are best suited to treat them.
Electromagnetic images can show where water flows during a hydraulic fracture. A test in the Anadarko Basin showed a fault there was a bigger hazard than expected. Electromagnetic (EM) reservoir imaging is likely to get more attention from operators thanks to a collaboration between Halliburton and a leader in this emerging technology, GroundMetrics. Carbo Ceramics is making big strides in the use of ceramic proppant.
Faster drilling speeds have become one of the major obsessions of the shale sector in recent years. But since completions represent up to 70% of a new well’s cost, maybe this side of the business needs more attention now. Fracturing two or more wells at the same time creates connections. While fracturing fluids reach out further, those ties create a stronger link, though not forever.
As the fallout deepens from the coronavirus pandemic and the global collapse in oil and gas prices, oil- and gas-producing regions around the world are feeling the pain. Digital advances allow computers to do many of the tedious tasks once done by engineers, which frees them to focus on more interesting tasks. The first interdisciplinary oil and gas conference to be held in Saudi Arabia, the 12th International Petroleum Technology Conference, was the largest in its history in attendance. This features highlights of the panel and technical sessions, and an interview with Saudi Aramco CEO Amin Nasser. The first of three major unconventional developments in Saudi Arabia has been given the green light.
Using drilling data and a downhole acoustic signal, developers aim to assess unconventional fracture networks in real time and give engineers ability to customize each stage. Techniques for well-abandonment log evaluations have been studied in the Gulf of Mexico since 2012. The new methods described in this paper consist of adding nuclear sensors to supplement the acoustic measurements and introduce novel processing methods. Since 2007, an operator in Nigeria has registered a significant increase of oil-spill events caused by sabotage and oil-theft activities. The technology presented here allows detecting and locating leaks taking place at a distance from the sensor of up to 35 km.
This paper describes a material designed to interact specifically with highly corroded and weathered pipe to enable in-place application and refurbishment. A new proppant exhibits a neutrally wet surface, which does not have a preferential affinity for oil, gas, or water and therefore will not promote the preferential entrapment of any phase within the proppant pack. Bitumen is so viscous that the ultraheavy crude oil is often compared to peanut butter.
