The presence of coal and coal-bearing rocks in waste rock dumps open-pit mines contributes to the occurrence spontaneous combustions that negatively affect environment people. Measurements temperature content hazardous gases anomaly arose dump mine were made assess parameters fire seats. In course study, efficiency detecting seats was assessed by measuring wells with a depth 2.5 m, drilled at d...

Two wells close to each other (Well A and Well B) have been selected from the same oilfield in southern Iraq. Both were drilled through Mishrif Reservoir, however, perforated within different sub-units. It was observed that one of shows obvious flow naturally while did not notice any kind flow.
 The type hydrocarbon interpretation by Gas drilling method (GWD), results confirmed both these ...

Abstract Horizontal wells are often drilled and hydraulically fractured in tight reservoirs to produce hydrocarbons or heat. Different fracturing fluids such as slick water, gas, foam, gel, a combination can be used with water being the most common fluid. In this paper, we study impacts of different on well productivity using an in-house integrated hydraulic reservoir simulator equation-of-stat...

Abstract The study area is located in Anbar Governorate, western Iraq, within the city of Ramadi, adjacent to Al-Warrar Canal. suffers from a lack previous hydraulically studies, hydrological, geological, and topographical characteristic soil characteristics, also significant increasing levels groundwater. Three wells were drilled canal with diameter 0.1524m, 10m depth 100 m distance between ea...

This study endeavor aims to provide a very detailed explanation of seismic reflection survey-based hydrocarbon exploration. The purpose the research is determine why some oil industry wells still remain dry after being drilled. Emphasis was placed on potential application innovative methods with goal developing novel response this trend. A more in-depth examination arguments for using technolog...

We present a hybrid, data-driven and physics-based method of forecasting play-wide gas production in the Haynesville Shale, which is currently second-largest shale producer US. first define several statistical well cohorts, one for each reservoir quality completion technology Haynesville. For cohort, we use Generalized Extreme Value (GEV) statistics to obtain historical average prototypes. The ...

The oil and gas industry plays a vital role in meeting the ever-growing energy demand of human race needed for its sustainable existence. Newer unconventional wells are drilled extraction hydrocarbons that requires advanced innovations to encounter challenges associated with drilling operations. type drill bits utilized any operation has an economical influence on overall operation. selection s...

One of the ways to resolve “green energy-economic development” dilemma, in which coal industry is situated, by improvement technologies and integrated use extracted resources, including methane gas as a clean energy source. Using example Kirova mine, located Kuznetsk basin—one ecologically unfavorable mining regions Russia—this article discusses an technology for extraction coalbed (ECBM), make...
