A Discriminant Analysis of Acquired and Acquiring Companies in the Oil Industry
Authors: Noble J. E. 
Published: December 2007

Abstract
The purpose of this study was to determine if there were financial and industrial characteristics of acquired and acquiring oil companies that would distinguish the companies in each group. A multivariate statistical technique, multiple discriminant analysis (MDA), was used to evaluate 24 financial and industrial variables and to develop a discriminant model that best discriminated between 14 acquired and acquiring companies.
Using the MDA technique, eight variables: sales/total assets, earnings/share growth, finding cost/barrel, times interest earned, PE ratio, the ratio of discounted future net cash flows/share to the average price/share of common, the ratio of commom equity to total capitalization, and inventory turnover were identified as those that would best distinquish the two groups. A discriminant function was derived using these variables.
Acquiring companies were characterized as having higher asset utilization, greater earnings-per-share growth, a higher percentage of commom in total capitalization, and greater inventory turnover. Acquired companies were characterized as having lower perbarrel finding costs and greater future net cash flow potential relative to their average cost/share of commom stock.
The study's findings generally support the opinion that the reorganization of the oil industry through mergers and acquisitions reflects a beneficial reallocation of the industry's assets to companies that place a higher value on their use and will, consequently, utilize those assets more efficiently.
Case History: Successful Drilling in the Altamont and Bluebell Fields of Utah's Uintah Basin
Authors: Trichel D. K. , McKinney W. E. , Bryant G. A. 
Published: December 2007

ABSTRACT
Some of the most challenging drilling encountered in the Uintah Basin of northeastern Utah occurs in the Altamont and Bluebell Fields (see Figure 4). Drilling costs in the area have been historically high due to such problems as surface water flows, lost circulation, abnormal pressure, hard and abrasive formations, and flows of crude oil with high concentrations of paraffin.1
Through implementation and improvement upon a carefully planned and executed drilling program, drilling costs in the area were reduced by 48%. All wells used in this study were drilled using a fully company owned and operated drilling rig. This paper details the improvements made in drilling fluids systems, hydraulics, bit selection, solids control, cementing practices, and other drilling related parameters pertinent to our drilling success.
Use of Expanding Cement Improves Bonding and Aids in Eliminating Annular Gas Migration in Hobbs Grayburg-San Andres Wells
Authors: Seidel F. A. , Greene T. G. 
Published: December 2007

ABSTRACT
Annular gas migration and poor cement bonding throughout much of the wellbore have been continual problems in the primary cementing of Hobbs Grayburg-San Andres Wells. This paper discusses the formulation of an expanding cement system and the implementation of good primary cementing techniques to improve cement bonding and to eliminate annular gas flow after cementing. The work is based on a review of previously unsuccessful attempts to control annular gas flow by conventional gas control methods typically used by the industry.
Case histories, cement bond logs, previous primary cement slurries, and procedures used in the field are presented with possible explanations of why they failed to control the problem. The formulation of the primary cement system is outlined in detail including refinements made to the system during the 1984-85 drilling program.
Evaluating Sour Gas Exploratory and Development Ventures
Authors: Honeycutt B. D. , Price B. C. , Gater J. E. 
Published: December 2007

ABSTRACT
An assessment of potential profitability of an exploratory venture in a sour gas play should include the large effect gas composition can have on plant cost. Based on expected composition, processing plant costs can vary six-fold, ranging from simple sweetening and dehydration units to those including sulfur recovery and tail gas units. Examination of basin trends may provide reasonable guidelines on expected variation in gas composition, hence the expected variation in both cost and profit. Data from three formations illustrate gas compositional variation. If gas composition varies widely in a play, expected plant cost can be calculated by weighing plant cost with chance of compositional occurrence.

"Electric Motor Selection and Sizing on Beam Pumping Wells to Minimize Energy Costs"
A.B. Neely, Shell Western E&P Inc.
The relative efficiency of very high slip and NEMA "D" electric motors has been widely debated. A test was carried out using both types on an instrumented well. When properly sized, the test showed that power consumption increased slightly and rod loading decreased slightly (up to ± 5%) with large increases in speed variation during the stroke. However, the most important finding was that power consumption could increase by a factor of two to three when the motor is significantly oversized. Details of the test will be presented.
The Politics of Energy Policy: A Congressional Perspective
Authors: Barrett M. F. 
Published: December 2007

Abstract
Diamonds, it is said, are created under great pressure. In the 1.26 decades since the oil embargo of 1973 and the beginning of the energy crisis, Congress has endured enough pressure to have created a great number of diamonds.
Some of the pressures came from advocates of increasing the supply of fossil fuels. An equal counterforce was exerted by conservationists who advocated restraints on demand. Congress chose a mixture of both: improving supply through supply incentives including the easing of environmental restrictions and dampening demand through the regulation of consumption and offering of conservation incentives.
I was present at the creation -- and frequently participated in the creation -- of the legislation which, in the latter half of the 1970s, came to be known as "national energy policy." That policy has been articulated in an alphabetic concatenation of legislative solutions -- EPCA, ECPA, EECA, NECPA, NEES, PMPA, PIFUA, ESECA, ESA, FERC, DOE, CAFE and more. Somewhere in there, there is concealed more than one jewel. Some of them, however, may require a considerable degree of polishing. Together they constitute a national energy policy crafted with great political acumen, in a reasonable bipartisan fashion and they work fairly well.
Effective Well Stimulations with Gelled Methanol/Carbon Dioxide Fracturing Fluids
Authors: Fairless C. M. , Joseph W. 
Published: December 2007

ABSTRACT
CO2 foam fracturing fluids with gelled methanol as the external phase have been developed. These CO2 foams are generated on the surface by a patented CO2 heating process. Field applications of these fluids demonstrate that they are effective well stimulation fluids for hydrocarbon bearing formations that exhibit low permeability, low reservoir pressure or water sensitivity.
With this system water can be completely eliminated from the treatment fluid while the CO2 provides a gas drive to assist in returning load fluid to the wellbore. Since the density of these fluids is near that of water, they can be utilized to fracture stimulate deep formations without experiencing excessive wellhead pressures. Some CO2 dissolves in the methanol to yield a non-damaging low "pH" methanol fluid system that exhibits extremely low surface tensions which also assists in load fluid recovery. Additionally, these fluids exhibit near perfect proppant support and very high fluid effeciencies.
A comparison of these surface generated methanol/CO2 foam fracture treatments with other stimulation methods in the Morrow formation in the Texas Panhandle and Western Oklahoma and in several other formations in Texas, Oklahoma and Colorado illustrates their success.
The Gas Research Institute's Tight Gas Sands Program in East Texas
Authors: Hathaway S. C. , Salehi I. 
Published: December 2007

ABSTRACT
For the past two years an extensive field-based research and development program has been ongoing in East Texas; if the results generated are to have the maximum impact on industry then the end user of these developments must be "in touch" with the program. To be exact, the Travis Peak/Hosston Formation of East Texas is being used as a laboratory for tight gas sand technology development. The Gas Research Institute's (GRI) Tight Gas Sands Program is able to bring such a diverse, but complimentary range of research to the field thanks to the cooperation of numerous East Texas operators. The objective is to develop the information, tools and diagnostic capability needed to increase the recovery effectiveness and reduce the costs of gas from tight sand reservoirs. This paper will serve as an introduction to GRI and to the East Texas-based field activities of the Tight Gas Sands Program, as well as extending an invitation to East Texas operators and service companies to take advantage of the research activities through direct participation.
Productive and Economic Potential of Tight Gas from the Travis Peak Formation in East Texas
Authors: Haas M. R. , Stone A. 
Published: December 2007

ABSTRACT
Increasing operator activity and a pending FERC tight formation designation for the Travis Peak formation in East Texas indicate its large potential. The overall potential reserve additions from applying improved reservoir evaluation and stimulation techniques, however, has not been clear in the currently changing environments of technology, prices, and taxes and regulation.
This paper fully analyzes the conjoint effects of current geological understanding, engineering and financial costs, and production technologies on Travis Peak potential. Cores and logs, well tests, and production data from current (tight) Travis Peak wells provide a detailed geological basis for the analysis. The combined effects of geology, technology, costing, and resource development are analyzed in a comprehensive study of individual or overall benefits in the Travis Peak of specified technology or production practice improvements. The knowledge gained from this analysis is useful to direct R&D efforts toward those technologies that most increase reserves in specific locations.
Analysis results show the Travis Peak has economic tight gas potential (per section of productive area) greater than that estimated for the better known Cotton Valley, but varying substantially by location. For a 6700 mi2 Study Area in East Texas, over 3.8 Tcf in potential reserves are available at current prices and technology. Sensitivity analyses of alternative reservoir evaluation and stimulation technologies are individually described in terms of their effects on reserves, production, and economics, potentially adding more than 50% in reserves at current prices.
The SPE Microcomputer Users Group and its Activities
Authors: Eckles W. W. 
Published: December 2007

SUMMARY
Microcomputer technology has begun to revolutionize petroleum engineering. Petroleum engineers' use of relatively inexpensive personal computers (PC's) is likely to continue expanding rapidly. Since 1982 SPE's Microcomputer Applications Committee has developed a Society-wide users group, a bi-monthly newsletter (MICROCOMP NEWS), a SPE Continuing Education Short Course, a Petroleum Industry Applications of Microcomputers Symposium, a hardware and software distribution program, and a world wide electronic network (SPE NET).
The purpose of this paper is to share SPE's experience in creating a dynamic program for meeting the individual member's need in the application of microcomputers to petroleum engineering. My hope is that this will encourage other engineering and scientific organizations to provide similar programs for their members.

Published: December 2007

ABSTRACT
The purpose of this paper is to discuss some key properties and design criteria of aluminum drill pipe leading to its substantial advantage over conventional steel drill pipe in doglegs or directional drilling.
Fatigue data from full section fatigue endurance tests comparing aluminum and steel drill pipe will be presented. The effect of well shape on drill string loads and torque is discussed by comparing steel and aluminum drill strings in build and hold and "S" shaped wells.
Additionally, a short section on corrosion resistance is also presented.
The results show the advantages of aluminum drill pipe over steel in directional drilling — better fatigue life, maximum permissible dogleg severity, reducing drill string drag and torque, reducing wear on tool joints, pipe body and casing, better resistance to stress corrosion and corrosion fatigue.
Standard Buggy Rack Inspection with Continuous Cross-Sectional Area Measurement
Authors: Curtis W. W. 
Published: December 2007

ABSTRACT
With used drill pipe it is important to know the minimum cross-sectional area (CSA) of the tube and the remaining wall in areas of pitting. Until now there has been no effective way to measure cross-sectional area or to evaluate remaining wall, over the full length, while rapidly scanning drill pipe with a standard buggy rack inspection. A buggy rack inspection tool has been developed which measures and displays the cross-sectional area over the full length of the tube, and provides a means to evaluate pitting based on average remaining wall.
This paper describes the device, test results, and the unique advantages of this addition to a standard buggy rack inspection.
Treatment Reclamation and Disposal Options for Drilling Muds and Cuttings
Authors: Hinds A. A. , Donovan D. M. , Lowell J. L. , Liao A. 
Published: December 2007

ABSTRACT
Concerns about the environmental impact of offshore drilling discharges have resulted in increasingly stringent conditions being imposed in general NPDES permits for the OCS areas. Similarly there is increasing concern for the potential adverse impact of drilling mud on ground water. Impending prohibitions (EPA) on the discharge of muds or cuttings contaminated with diesel oil or containing "high trace metal" barites underscore the degree of concern. As a consequence, increasingly large volumes of mud and cuttings are being transported to shore for treatment and disposal.
The principal methods of mud and cuttings disposal are reviewed and the potential environmental impact assessed.
A novel approach to the reclamation and disposal of drilling muds is presented. The treatment process developed employs mechanical solids – liquid separation; chemical stabilization and fixation of solids; and chemical coagulation/flocculation of the effluent to meet water quality discharge criteria or for re-use in mud formulation. The process can accommodate water-base and oil-base muds (OBM) and cuttings. Oil from OBM is recycled and used for mud formulation.
Factors influencing the effectiveness of polymers in removing dispersed solids and heavy metals were investigated and comparative cost data for different treatment regimes employing polymers and/or polyvalent metal salts developed.
Permeability Impairment Due to Fines Migration in Sandstones
Authors: Sharma M. M. , Yortsos Y. C. 
Published: December 2007

ABSTRACT
In a previous publication1 critera were derived for predicting the onset of fines release in sandstones. The present paper describes quantitatively the behavior of the sandstone after the fines have been released. The entrapment of fines at pore throats is modelled using a statistical approach and general population balance equations are written for the various species of interest. The equations are solved for the open pore densities and size distributions, for some special cases. The Effective Medium Theory is used to calculate the permeability once these are specified. The model therefore provides permeability as a function of time and position i.e. the extent and depth of damage. Such information will be valuable in not just predicting formation damage but also in designing appropriate stimulation jobs once the damage has occured.
Acidization of Dirty Sandstones with Buffered HF Acid Systems
Authors: Smith M. J. , Clark G. J. , Hendrickson A. R. , Egbogah E. O. 
Published: December 2007

ABSTRACT
Previous studies have shown that acidization of sandstone with 12% HCl/3% HF acid systems can lead to secondary precipitation of many different compounds. Formation of these precipitate often have been found to be pH dependent. If the pH of spent HF formulations can be kept low, the likelihood of secondary precipitation may be reduced. This paper presents the results of a study showing the effect of acidizing a Berea Sandstone (76 × 5 cm), containing 9% carbonate, with a buffered HF acid system (12% H3PO4/3% HF). These results are then compared to results with 12% HCl/3%HF.
Treatment with one pore volume of the buffered acid system was found to increase the native permeability of the Berea sandstone core to a depth of 60 cm. No evidence of damaging precipitation or unconsolidation was found in any section of the core. The pH of the reacted acid was found to be low (2.0 – 2.5).
Fourteen pore volumes of HCl/HF increased the permeability only to depth of 25 cm and caused unconsolidation of the first 10 cm and 0.5 pore volume of HCl/HF caused formation of damaging precipitates.
The absence of secondary precipitation with 12% H3PO4/3% HF is most likely due to two factors: the buffering ability of the phosphoric acid kept the pH low and hence prevented precipitation of silicon or aluminium complexes, and the unique surface reactions between calcite and 12% H3PO4/3% HF prevent large amounts of calcium ions from being brought into solution from reaction with the carbonate content of the sandstone. These two factors were confirmed by reacting 12% H3PO4/3% HF with synthetic sandstone like mineral blends.
Solids-Free Brines: Efficient Displacement Techniques can Save You Money
Authors: Krause D. C. 
Published: December 2007

ABSTRACT
Effective removal of drilling muds and related solids from well bores has been a topic of major concern for several decades. Displacement of incompatible fluids such as drilling mud with solids free brine is a critical point during well operations. A clean efficient displacement is mandatory to maintain the brine and mud integrity, reduce filtration costs, reduce rig time and provide a solids free environment in the well. The net result – downhole operations become easier, faster, and more effective in clean fluids.
The displacement process is divided into two components: Predisplacement – the mechanical and chemical conditioning of the mud before it is actually displaced.Displacement – the actual removal of the mud from the well using appropriate spacers, chemical washes and technique.
Methods to analyze and compare displacements are proposed.
The Management of Renqiu Oilfield During its Medium-Late Development Stage
Authors: Liu Renda 
Published: December 2007

ABSTRACT
The production performance of Renqiu oilfield, which is a fractured massive carbonate reservoir with bottom water has indicated the remarkable blocking characteristic controlled mainly by inner faulted structures and karst formation.
Based on a comprehensive study on the data of the faulted structures, Karst formations and reservoir performance, the oilfield has been divided into eight development a blocks falling respectively into one of the three types: dolomite with well-developed high angled fractures, dolomite with fairly homogeneously developed fractures and cavities and intercalated dolomites with extremely heterogeneously developed crevices and fractures.
In view of the geological and development a characteristics of each type, proper technologies have been employed in the management of the oilfield. This has been done with fairly good results. Production decline rate has been controlled, production of a single well increased, interference from water producing zones in the open holes reduced, production potential in the formations with poorly developed fractures tapped, and recovery of the sections below interfaces raised. All of these will greatly improve the development of the oilfield in its medium-late stage.
A Point Bar Facies Reservoir Model – Semi-Communicated Sandbody
Authors: Xue Peihua 
Published: December 2007

ABSTRACT
It is indicated in the secondary recovery practices that in the course of development by waterflooding, the point bar reservoir of meandering channel deposition generally shows a complicated production performance, poor development results and low ultimate recovery, estimated as about 30%.
Furthermore, it shows that this type of reservoir has a great potential with the estimated remaining oil reserve of more than 50% based on the analysis of swept thickness and water displacement efficiency of the reservoir by an examination of the data from inspection wells. How to tap the potentialities and how to improve the ultimate recovery of this type of reservoir are the primary issues that are commonly concern personnel in the petroleum industry.
In this article, from a developmental, geological point of view, modern deposits study is used, combining some case histories to analyze the geological factors which affect the present development results in which heterogeneous characteristics of point bar reservoir were the main items studied. Results of some related numerical simulations have been used and the program of mixed injection water and gas which can possibly increase the recovery factor by 16% have also been discussed, in order to further establish, perfect and prove the practices and the theory of semi-continuum reservoir model for the point bar facies sand body.
