水平井完井方法研究和优选

水平井的完井技术是整个水平井开发过程中最重要的组成部分,水平井完井方式是否选择得当直接关系到油井以后的开发过程能否顺利进行。水平井完井可以依据不同的生产限制条件和油藏特点运用不同的方法进行完井。完井方法的选择直接受岩石强度、是否需要堵水堵气、预期流动率、完井寿命、页岩的活动性和稳定性、颗粒排序和纹理的影响。在该文中,展示了各种可能的水平井完井方法。通过对比得到了最优的防砂完井方式,同时结合现场应用情况证明了裸眼筛管砾石充填完井方式的优越性。     

Time to completion in the Lagos commercial real estate market: an examination of institutional effects

This study explores how institutions affect the process of investment and the time it takes to buy and sell commercial property in Lagos, Nigeria. We isolate institutional factors that impact transaction efficiency and provide a snapshot of the process with average transaction times for the largest commercial real estate market in the most populous country in Africa. This study adopts a qualitative approach and relies on information collected from semi-structured interviews with 36 senior level individuals active in the Lagos commercial real estate market. Among our findings, we note the commercial real estate transaction process is divided into seven distinct stages and the average time to complete an acquisition across all stages (all property types) is 306 days. Title registration/perfection stage takes the longest time (around 132 days) and represents a significant risk to investors. We argue this is a consequence of imperfections in the formal institutions of title registration.

工程施工和竣工结算阶段的工程造价控制

工程造价控制是建设管理的一个核心部分,它始终贯穿于工程建设的全过程,即体现在对工程建设前期可行性研究、投资决策、到设计施工再到竣工交付使用前所需全部建设费用的确定、控制、监督和管理。本文对工程施工和竣工结算阶段工程造价控制进行了探讨。     

Progress billing method of accounting for long-term construction contracts

This article questions the reliability of the amount of revenue recognized in the percentage of completion （POC） method of revenue recognition in construction industry and recommends a new method based on the progress billing which is more reliable. The most commonly used method of revenue recognition in the construction industry is the percentage of completion method （POC）, where the revenue is recognized on the basis of the percentage of work completed. The calculation of percentage of work completed is made on the basis of the cost incurred for the contract work during the financial period and the cost required for completion of the work as estimated by the contractor. Here, the acceptance of the product by the buyer （contractee） is not involved in recognizing the revenue. The reliability of the amount of revenue and its collectability can be assured only when the buyer accepts the product. The approval of the progress bill by the contractee is needed to assure the reliability and collectability and it must be the event that triggers the recognition of revenue.     

A contextual theory of organizational learning from failures and successes: A study of acquisition completion in the global newspaper industry, 1981–2008

This study develops and tests theory about the context‐specificity and outcome‐dependence of experiential learning in acquisition processes. First, we investigate whether learning from experience gained in different acquisition contexts is limited to influencing subsequent outcomes of same‐context transactions. Second, we analyze whether learning patterns in response to prior successes and failures differ across acquisition contexts, depending on two properties of these contexts—the degree of structural variance and the level of stimulation of deliberate learning. Learning is assessed with respect to an underexplored organizational goal variable in acquisitions: completion of a publicly announced transaction. An analysis of 4,973 acquisition attempts in the newspaper industry in 1981–2008 largely supports our theory. Copyright © 2012 John Wiley & Sons, Ltd.
