U.S. tight oil shale oil production 11-01-18 permian Eagle Ford Bakken Bonespring Wolfcamp Spraberry Woodford

Figure 1 shows the United Stated Tight Oil Production in percentages. We can see here which are the main Tight Oil producers in U.S.: Spraberry, Bakken, Eagle Ford, Wolfcamp, Bonespring and Niobrara-Codell are the six biggest tight oil players in the United State controlling 89% of the total tight oil

Tight oil market dynamics: Benchmarks, breakeven points,and inelasticities

Fig. 7. U.S. tight oil and shale gas drilled but uncompleted wells (EIA, 2017b) (dotted curve, right axis) and West Texas Intermediate crude oil price (EIA, 2017c) (solid curve, left axis) from January 2014 to April 2017.

Abstract When comparing oil and gas projects - their relative attractiveness, robustness, and contribution to markets - various dollar per barrel benchmarks are quoted in the literature and in public debates. Among these benchmarks are a variety of breakeven points (also called breakeven costs or breakeven prices), widely used to predict

The effect of interbedding on shale reservoir properties Kimmeridge Clay Formation

Abstract North Sea oil is overwhelmingly generated in shales of the Upper Jurassic – basal Cretaceous Kimmeridge Clay Formation. Once generated, the oil is expelled and ultimately migrates to accumulate in sandstone or carbonate reservoirs. The source rock shales, however, still contain the portion of the oil that was not expelled.

U.S. dry shale gas production 2018

The total production of dry shale gas in the United States in the month of November 2018 was 63,36bcf per day: Marcellus, Permian, Utica, Eagle Ford, Bakken, Haynesville

Figure 1 shows the United Stated Dry Shale Gas Production in percentages. We can see here which are the main shale gas producers in U.S: Marcellus, Permian,  Utica,  Haynesville and  Eagle Ford are the biggest shale gas players in USA controlling 74,3% of the total shale gas production with Marcellus

Groundwater baseline water quality in a shale gas exploration site and fracturing fluid-shale rock interaction

Fig. 2 The shallow groundwater chemical composition

At present, the baseline water quality must be firstly obtained to identify potential pollution of the activity and monitoring indicators should be studied for better environmental monitoring. We sampled shallow groundwater, produced waters, shale rock and soil in the Jiaoshiba shale-gas region, SW China and measurements have included water chemistry

Pore evolution in hydrocarbon-generation simulation of organic matter-rich muddy shale

Fig. 4. FESEM images of carbonaceous mudstone and the simulated samples at different temperatures.

However, in the high mature-overmature stage, shale porosity decreased with further increase of temperature and pressure. In contrast to micropores, micro-scale capillary pores and megapores in shale constantly decreased as rise of simulation temperature or pressure, indicating that deep-burial reservoirs was not favorable for free-gas storage; but significant increase of

Displaying Well Control Incident Data in Petrel; a Workflow for Promoting Rig Safety Across Disciplines

In the worst cases, these can lead to loss of rigs or loss of life. Fig 1. Drilling tour sheet denoting loss of rig due to kick/blowout. On the Engineering side of well planning, it is a common practice in the Oil and Gas industry to mitigate the risk of kicks and

Microstructural imaging and characterization of oil shale before and after pyrolysis

Fig. 13. (A) Porosity of 10 oil shale samples after pyrolysis at 500 °C, (B) – (D). 2-D gray scale images for organic-rich, organic-mixed and organic-lean regions respectively. (E) – (G) 3-D rendered volumes with the pore space visualized in blue.

Abstract The microstructural evaluation of oil shale is challenging which demands the use of several complementary methods. In particular, an improved insight into the pore network structure and connectivity before, during, and after oil shale pyrolysis is critical to understanding hydrocarbon flow behavior and enhancing recovery. In this experimental study, bulk

Mechanism of multi-stage sand filling stimulation in horizontal shale gas well development

Fig. 1. Body-centered cubic and face-centered cubic models of equant spheres.

With consideration to the limitations in the implementation of the mechanical staging technique with bridge plug for shale gas development in the Sichuan–Chongqing area, the technique of multi-stage sand filling stimulation in horizontal wells was proposed to solve the above-mentioned problems. By filling sands in fractures, it is possible to

Microstructures of Early Jurassic (Toarcian) shales of Northern Europe

Abstract The Toarcian (Early Jurassic) Posidonia Shale Formation is a possible unconventional gas source in Northern Europe and occurs within the ClevelandBasin (United Kingdom), the Anglo-Paris Basin (France), the Lower Saxony Basinand the Southwest Germany Basin (Germany), and the Roer Valley Graben, the West Netherlands Basin, Broad Fourteens Basin, the Central

Strengthening shale wellbore with silica nanoparticles drilling fluid

Fig. 7. SEM images of shale surface (a) nanoparticles within shale and (b) aggregate of nanoparticles plugging a pore throat.

Higher concentration of nanoparticles can induce better plugging effect. However, for the OBDFs, nanoparticles did not show these positive effects like the nano WBDFs, even leaded to some negative effects such as higher filtration and larger Young's-modulus reduction. The main reasons are that the silica nanoparticles can easily disperse in

Deformation mechanism of horizontal shale gas well production casing and its engineering solution: A case study on the Huangjinba Block of the Zhaotong National Shale Gas Demonstration Zone

Fig. 5. Three-dimensional imaging interpretation of multiple bending deformation of casing in Well H1-2.

It is shown that severe casing deformation tends to occur where structural fractures are developed. Besides, casing deformation is mainly in the form of “S”-shape bending vertically. The severely deformed casing is also characterized by obviously transverse shear deformation caused by the high-angle sliding compression of rocks. Therefore, some suggestions

Current research into the use of supercritical CO2 technology in shale gas exploitation

Fig. 3. Surface comparison of shale before and after ScCO2 fluid treatment (10 MPa, 50 °C) [53].

The research findings indicate that ScCO2 fluid replacement can be used to increase gas production and seal up greenhouse gases as an effective, clean and safe method of shale gas exploitation. It is particularly effective for promoting the desorption of CH4 in shale reservoirs that have developed fine neck-wide body

Data on shale-water based drilling fluid interaction for drilling operation

Data on shale-water based drilling fluid interaction for drilling operation

The dispersion test was conducted, and it involves exposing a weighted quantity of sized shale to the formulated mud in roller-oven. This test is used to design fluids and screen the effectiveness of inhibitor additives to maintain the integrity of the cuttings and minimize the interaction of fluids with the
