<p>A new method has been developed for modeling acoustic monitoring of a layered-block elastic medium with several inclusions of various physical, mechanical and phase hierarchical structures. An iterative process is developed for solving the direct problem for the case of three hierarchical inclusions of l, m, s-th ranks based on the use of 2D integral-differential equations. The degree of hierarchy of inclusions is determined by the values ​​of their ranks, which can be different. Hierarchical inclusions are located in one layer: the first is anomalously dense, the second is anomalously plastic, and the third is anomalously elastic and fluid-saturated density. The degree of filling with inclusions of each rank for all three hierarchical inclusions is different. The simulation results can be used in monitoring studies of the control of fluid return from oil fields developed as part of horizontal drilling.</p><p> </p>

Summary When the oil price is low, cost optimization is vital, especially in mature oil fields. Reducing lifting costs by increasing the mean time between failure and the overall system efficiency helps to keep wells economical and increase the final recovery factor. A significant portion of artificially lifted wells currently use sucker rod pumping systems. Although its efficiency is in the upper range, there is still room for improvement compared with other artificial-liftsystems. This paper presents the field-tested sucker rod antibuckling system (SRABS), which prevents buckling of the entire sucker rod string, achieved by a redesign of the standing valve, the advantageous use of the dynamic liquid level, and, on a case-by-case basis, application of a tension element. The system allows full buckling prevention and a reduction of the overall stresses in the sucker rod string. The resulting reduction in the number of well interventions combined with the higher system efficiency prolongs economic production in mature oil fields, even in times of low oil prices. The analysis of SRABS, using finite-element simulations, showed a significant increase in system efficiency. The SRABS performance and wear tests under large-scale conditions were performed at Montanuniversität Leoben’s Pump Test Facility and in the oil field. The results of intensive laboratory testing were used to optimize the pump-body geometry and improve the wear resistance by selecting optimal materials for the individual pump components. The ongoing field-test evaluation confirmed the theoretical approach and showed the benefits achieved by using SRABS. SRABS itself can be applied within every sucker rod pumping system; the installation is as convenient as a standard pump, and manufacturing costs are comparable with those of a standard pump. This paper shows improved performance of the SRABS pumping system compared with a standard sucker rod pump. SRABS is one of the first systems that prevents the sucker rod string from buckling without any additional equipment, such as sinker bars. Testing of SRABS has identified significant benefits compared with standard sucker rod pumps.

Degradation Ability

Two kinds of polyacrylamide(HPAM)-degrading bacteria S1, S2, which can use HPAM as only nitrogen source and the sole carbon source, were isolated from petroleum-contaminated soil of Daqing Oilfield. The bioremediation for treating petroleum contaminated soil by immobilized microorganisms can improve the effect on biodegradation for pollutants in oil fields and reduce the loss of bacteria. The degradation ability of five kinds of embedding immobilization methods on soil pollutant was investigated. The experimental results showed that the immobilized microbial granules, which used polyvinyl alcohols (PVA) and sodium alginate as coagulant, activated carbon as coagulant-support, exhibited good mechanical strength, operated easily, be not breakable and low cost. Experiments results showed that after treatment using this kind of immobilized microbial granules, the HPAM concentration declined from 500 mg•L-1 to 102 mg•L-1 in 48 hours. The degradation rate of HPAM reached 79.6%. At the same time crude oil content decreased from 733.21 mg•L-1 to 9.5 mg•L-1. These immobilized microbial granules can remove 98.7% oil from the petroleum-contaminated soil in 48 hours.

Organic Facies

Horizontal drilling and multistage fracturing designs have recently made the Wolfcamp shale horizons a highly sought-after and low-cost oil opportunity at a time of market volatility. One current challenge is that the Wolfcamp shale horizons are unpredictable, especially in acreages with limited well control and seismic data. Sedimentary organic matter (palynofacies) analysis can delineate thermal maturity windows, determine kerogen types, and reflect depositional environments to aid in realizing hydrocarbon potential. We palynologically processed 16 samples at roughly 3 m intervals from the upper Wolfcamp section of the Collier-1201 well in Reeves County, Texas. We examined the prepared microscope slides in transmitted light to quantify (point count) and describe the organic facies in each sample. Additionally, we integrated organic geochemical data to corroborate palynofacies analysis. We classified most of the observed organic matter particles as highly degraded phytoclasts with unidentifiable terrestrial palynomorphs. The palynofacies and organic geochemical data indicate a mixed type-II/III kerogen (oil- and gas-prone materials) characterized by substantial terrigenous input. All samples displayed a high degree of thermal maturity from immense overburden as the Delaware Basin subsided and the overlying beds compacted. The lithologic and organic facies of the studied interval reflect fluctuating proximal marine conditions.
