... polymer degradation, injectivity, and retention. With the increased awareness of the importance of water chemistry, this paper investigates the effect of make-up water composition on an ATBS (Acrylamido-Tertiary-Butyl Sulfonate)-based polymer performance focusing on polymer-rock interactions...

.... This study addresses this lack of clarity in the wireline logs by utilising borehole images from one well in the Mauddud Formation. In particular, this study characterises the sedimentological make-up and reservoir quality of the carbonate deposits within the Mauddud Formation using FMI data...

... Abstract Phosphate conversion coatings are widely used on (premium) casing connections for protection against corrosion. Next to that, in conjunction with the lubricant these coatings provide galling protection. The friction and wear that occurs during make-up and subsequent load cycling...

... Abstract Water treatment systems used to recycle produced water and/or make-up water for the production of steam used in the SAGD and CSS processes have noted failures associated with erosion-corrosion, under deposit corrosion, and fouling/scaling. Oil sands operators employ corrosion...

... Abstract Declining marginal profits demand that operating companies and drilling contractors review their practices and examine ways to optimize processes and reduce unplanned expenditures. One area that has been largely overlooked is iron roughneck make up torque. Until recently, most iron...

...-lightweight proppant Background For openhole well completions, gravel packing is a typical sand control solution. Traditionally, formations with multiple sands, shale layers, or water sands are poor candidates for openhole gravel packing. Unstable formations make operations difficult and sometimes...

... Abstract Polymer flooding is a mature EOR technique, which is successfully applied in both sandstone and carbonate reservoirs. In ongoing polymer projects, make-up brine is either formation water, sea water or any available water sources like deep or shallow aquifers. In this paper we focus...

... Proposal When tubing-conveyed perforating (TCP)-guns have been needed, the traditional make-up method has been for the TCP and rig personnel to make them up manually using pipe wrenches on the rig floor. Efficiency in these efforts is critical to ensure a safe and reliable operation. When...

... to 10,800 ft-lbs, reached infinite life, assumed to be 20 million cycles. At 9,550 psi bending stress, the samples with 10,800 ft-lbs and 16,300 ft-lbs make-up torque failed after 1,150,818 and 781,481 cycles respectively. The sample that was made-up to 5,400 ft-lbs achieved infinite life. Each...

... R t = Average mean radius of thread (in) With the basic premise for how make-up torque is calculated now defined, the next important concept to investigate is the RSC Combined Load Curve (CLC). Details related to this material are also well documented, so will not be fully explained...

... Abstract Subsea installations of large diameter flanged connections can prove to be costly and dangerous. The use of Taper-Lok connectors for subsea make-up of tie-ins and manifold connections during the installation of the BP Bombax Pipeline Project provided safer and faster connection make...

..., but they usually involve many of the following steps: Collect and gather all the relevant reservoir data, Perform quality assurance on the data and rationalize any inconsistencies, Build a model, or possibly a few models, Run simulations, including sensitivities, If history matching then make...

... tunnelling activity in the central part of the Swiss Alps has raised concerns with respect to encountering geotechnically difficult zones. Studies on the structural make-up and the geophysical and mechanical properties of brittle fault zones have already been reported, for example, by Chester and Logan (1986...

... declined in this decade due to the slump in the aerospace and defense industries after the cold war S. This has freed up a significant amount of titanium stock for the open market. Also, titanium alloys can be designed to develop high mechanical strength. Since titanium has a relatively low density (4.7 g...

..., cooling tower make-up is the most likely candidate for use of reclaimed water. Although reclaimed water potentially offers many environmental, political, and economical benefits, its use poses many challenges to the successful treatment of an industrial cooling system. This paper presents the major...

... ABSTRACT This paper discusses the successful use of treated municipal plant waste water effluent (Title 22) in a refinery cooling water system. Conversion from well water to this make-up water source was preceded by developing a carefully crafted transition plan. Steps were taken to identify...

... ABSTRACT Treated sewage water as make-up to the cooling tower requires novel approaches to control potential cooling water problems common to refineries besides meeting environmental regulations. An intensive field study was conducted to evaluate the effectiveness of non-chromate treatment...
