  Trends in Petroleum Engineering- (TPE)| Stephy Publishers Abstract: Previously we prepared fracturing linear gel with fossil diesel, bio-diesel and also used suspending, anti-settling agents and emulsifiers. But through this research, a novel and efficient method for the preparation of linear gel directly mixed with water, guar gum and sodium acetate together instantly. In this instead of diesel, we used water and no need to mix anti-settling agents, suspending agents, emulsifiers that resulted in 30 viscosity linear gel. Ammonium persulphate or Ammonium peroxidisulphate and enzyme-G are used for oxidation purposes to break the gel gradually at a particular static temperature. The degradation pattern observed from the breaker test showed that a reduction in gel viscosity depends on time, temperature & breaker concentration. Observations from experiments revealed that a small concentration of breakers provides rapid break compared to oxidative breakers. This article, designing...

  Trends in Petroleum Engineering - (TPE)|  Stephy Publishers Abstract High demand for oil and gas has led to exploration of more petroleum resources even at remote areas. The petroleum resources are found in deeper subsurface formations and drilling into such formations requires a well-designed drilling mud with suitable rheological properties in order to avoid or reduce associated drilling problems. This is because rheological properties of drilling muds have considerable effect on the drilling operation and cleaning of the wellbore. Mud engineers therefore use mud additives to influence the properties and functions of the drilling fluid to obtain the desired drilling mud properties especially rheological properties. This study investigated and compared the impact of barite and hematite as weighting agents for water-based drilling muds and their influence on the rheology. Water-based muds of different concentrations of weighting agents (5%, 10%, 15% and 20% of the total weig...

  Trends in Petroleum Engineering - (TPE)| Stephy Publishers Abstract Hydraulic oscillator is one of the effective tools to solve the problem of high friction in directional drilling and horizontal drilling. However, there are some problems with this kind of tools such as high pressure loss and insufficient vibration force. Because of its self-excited oscillation characteristics, pulse oscillation amplifier can realize the amplification of pulse jet pressure under the condition of lowpressure loss, which is one of the effective ways to solve the above problems of hydraulic oscillator. In this paper, according to the working characteristics of hydraulic oscillator and the demand of pulse amplification, the structure of pulse oscillator amplifier was optimized based on numerical simulation method. Firstly, the geometric and numerical models of the pulse oscillator amplifier were constructed, and the flow field distribution and pulse amplification effect of the pulse oscillation amp...

  Trends in Petroleum Engineering - (TPE)| Stephy Publishers Abstract Phthalic anhydride is the chemical that results from the oxidation of orthoxylene or naphthalene. In the USA, about 9 percent of phthalic anhydride came from naphthalene in2003. The remainder came from ortho-xylene. Keywords Phthalic anhydride, Vacuum distillation system, OX Introduction Phthalic anhydride is an organic compound that has a chemical the formula C6H4(CO)2O. It is the anhydride of phthalic acid. Phthalic anhydride uses enter in many applications such as construction, marine, transportation applications, automotive applications, furniture, fixtures, market declining and it enters in the manufacturing of the following compounds: 1,2 Phthalate plasticizers (68%) for PVC compounds Unsaturated polyesters (17%) To read more # PetroleumEngineering https://www.stephypublishers.com/tpe/fulltext/TPE.MS.ID.000505.php More #Openaccessjournals https://www.stephypublishers.com/
