  • Understanding the potential class II – Division I Safety Hazards present when operating Vertical Cuttings Dryers

    For decades, the industry standard for waste management dryers (a.k.a. vertical cuttings dryers) has relied on belt-driven sheaves. Though belt-driven systems are cost effective and relatively easy to implement, at a minimum they have represented a maintenance nuisance, at worst they represent a serious safety concern when ...

  • Common challenges relative to the use of Decanter Centrifuges for barite recovery in the oil & gas industry

    When centrifuges are properly deployed, they can have dramatic effects on drilling performance. In fact, without them, many of the advances made in drilling would not have been considered achievable. Classically, we believe that centrifuges can achieve two common goals: Reduce the content of drilled fines, specifically colloidal solids, and Perform barite recovery in order to reduce ...

  • The association effect of quaternary ammonium salt on carboxymethyl cellulose and its analytical applications

    Sodium carboxymethyl cellulose (CMC) has been extensively used in petroleum, geology, common household chemicals, food, medicine and other industries, owing to its excellent water-soluble, emulsifying, water retention and film forming properties. It is known as ‘industrial monosodium glutamate’. However, the research of the test method on CMC is far behind the research of its actual ...

  • Drilling Muds and Drill Cuttings Recovery for Beneficial Reuse

    Drilling Muds Drilling mud, also known as drilling fluid, is a vital component of the drilling process. It helps in the process of drilling boreholes into the earth where holes are required for extraction of oil and gas, core sampling and various other purposes. It is broadly of three types, including water-based, oil-based, and synthetic-based. Among all of these, synthetic-based muds ...

  • Principles of HDD Solids Control & Buyers Guide

    Relative to the use of drilling fluids within the oil & gas industry, the use of drilling fluids within the horizontal directional drilling (“HDD”) industry, is new.   As the use of HDD technology did not become mainstream until the 1980’s, it took another decade before drillers started to consider the use of basic drilling fluids.  Even today, ...

  • Centrifuge Technology in Drilling Fluid Recycling

    Drilling fluid additives and the water that contains them are an essential part and expense of successfully completing a horizontal directional drilling (HDD) installation, and the longer the bore and larger the product being installed, the more drilling fluids cost. Therefore, it makes economic sense to recycle drilling fluids by removing cuttings and recirculating the cleaned ...

  • Principles of Solids Control

    Although the use of drilling fluids within the HDD / trenchless industry is still relatively new, recent trends suggest that this standard is shifting as solids control is one of the most important phases in the drilling process. This shift is due to a growing awareness that drilling fluid maintenance and disposal can become exponential problems as they are both harmful to the environment and ...

  • Upgrading Water Injection Pumps

    Water injection pumps that are used in oil exploration typically face extreme abrasion, chemical attack, and cavitation erosion in their daily operation. The injected water is frequently loaded with abrasive particles, such as quartz sand, which quickly erode conventional pump surfaces. Sulzer’s service teams offer solutions to increase the lifetime and the performance of water injection ...

  • Construction materials production. Application of the ABC-100 unit

    Expanded clay industry In the process of expanded clay production the argillous raw material homogenizes and mills in the drilling mud mixers and rollers. But these equipments not ensure qualitative desintegration. As result we obtain the expanded clay of low quality. Insufficiently desintegration and homogenizing of raw materials lead to the result when even 3% of carbonate ...

  • SAS drilling mud cleaning products

    Effective & fast mud cleaning for the oilfield. SAS microemulsion drilling mud cleaning products speed up the cleaning and removal of drilling mud waste. The cleaning of drilling mud residues from mud pits, offshore supply vessels and mud trucks is traditionally a time consuming task. Using high pressure water or standard cleaning detergents usually results in large volumes of mud slop ...

  • Industry leading drilling fluid dewatering

    The drilling industry is regulated by a myriad of environmental regulations that protect our air, water, and land resources. As these regulations continue to evolve, so too must the technologies utilized by the drilling industry. Though lowering compliance costs is always a worthy initiative, incorporating technology that also enhances the drilling process by improving down-hole conditions and ...

  • Experimental study of the effect of temperature on the flow behaviour of oil-based muds in Niger delta formation

    The behaviour of the drilling fluids under high temperature is extremely important for drilling deep wells. Most commercial oil-base drilling fluid systems have limitations such as reduced rheology and filtration control if the fluid is exposed to higher temperature for prolonged periods of time. Formulating a drilling fluid system that can adequately withstand drilling in a high temperature ...

  • Why Bentonite Hurts Well Production: The Case for Biopolymer Drilling Fluid

    Bentonite is a naturally-occurring clay material, largely composed of the mineral, sodium mont-morillonite. The dominant property of bentonite is that it swells to many times its dry volume when hydrated by water, forming a viscous fluid with high gel strength. This makes bentonite an excellent product when used as a sealant, for preventing the influx of surface water into a well, sealing ...

  • Getting ahead of the Caribou - pitdry process—innovative solidification solution for spent drilling fluids

    An oil company has been producing oil and gas in British Columbia’s Southern Foothills since 1992. The operator has continuously invested in the area and recently opened up new gas producing wells northwest of Fort St John, the largest city in the northeast region of British Columbia. The new wells are situated 4,600 feet above sea level in a rigid mountain terrain. The viable way to connect the ...
