Abstract In 2017, blowouts and then explosions occurred in a Middle Eastern oilfield. A root cause of the incident is lack study investigation past kicks data. Therefore, as pioneer work region, data gathering analysis were made studied oilfield to learn lessons find gaps. Out 149 drilled wells, total 117 three (3) occurred. this work, list drilling parameters be considered suggested guideline ...

Buluh Cina Village, Siak Hulu District, Kampar Regency has problems with the availability of clean water. The water that residents use comes from dug/drilled wells smell sulfur. This condition is not under drinking requirements standardized by Indonesian Ministry Health through Permen Kes No. 492/MENKES/PER/IV/2010. There needs to be a solution overcome problem in Village. install filter for an...

Most hermit crabs depend on empty gastropod shells for shelter; competition for appropriate shells is often severe. This study determined whether shells that have been drilled by naticid gastropods are suitable for occupancy by the hermit crab Pagurus longicarpus. Differences in the characteristics of empty shells and those occupied by hermit crabs were assessed at two adjacent field sites in N...

The estimated ultimate recovery (EUR) of shale gas is an important index for evaluating the production capacity horizontal wells. Weiyuan field has wells with considerable EUR differentiation, which hinders prediction new Accordingly, 121 highly differentiated are used analysis. First, main control factors well identified via single-factor and multi-factor analyses, set as index. Subsequently, ...

The history of vertical drainage wells began in 1923 the United States America and since 1950 Uzbekistan. Such scientific researchers as N. Reshetkina, Kh. Yakubov, A Umarov, Z. Pushkarev, Nasonov, I. Akhmedov, other scientists worked on designing constructing wells. study aims to develop recommendations for improving sustainable operation based their design construction, considering natural ec...

In this study, drinking water sources including drilled wells (DW), tankers (WT), stabilized tanks (SWT), and plastic bottles (PB) as sequential sample were assessed at Dhamar City, Yemen to investigate the microbial contamination potential risk of using indicators multiple antibiotic resistance index. The involving, 5 wells, 10 tankers, 20 tanks, 100 bottles. study encompassed five samples. Ea...

The thermochemical degradation of hafnium silicate (HfSiO4) was investigated with a molten calcium-magnesium-aluminosilicate (CMAS) glass relevant to gas turbine engine applications. Sintered HfSiO4 coupons were fabricated, within which wells drilled and filled CMAS powder at loading ∼35 mg/cm2. Samples heat treated 1200°C, 1300°C, 1400°C, 1500°C for 1 h, 10 50 h. At 1200°C slow formation Ca2Hf...

The article presents the results of geophysical observations by Dnepropetrovsk expedition «Dneprogeofizika» on Zmiyinyy Island, which performed a full cycle work from prospecting and surveying studies to providing island with drinking water.
 In structural tectonic conditions, is considered as insular block Danubian horst megablock. geodynamics region determined position inclination collis...

distinguishing productive zones of a drilled oil well plays a very important role for petroleum engineers to decide where to perforate to produce oil. conventionally, net pay zones are determined by applying a set of cut-offs on perophysical logs. as a result, the conventional method finds productive intervals crisply. in this investigation, a net index value is proposed, then; diffusivity equa...
