Managed Pressure Drilling Services, an Alternative to Traditional Overbalance Drilling

 

Managed pressure drilling is a drilling process that is used to precisely control the annular pressure profile across the wellbore. Managed pressure drilling services use a pressurized and enclosed circulation system to provide precise wellbore control. Managed pressure drilling does not manipulate the window, (pore pressure and fracture gradient), instead helps the operator to remain in that window. Moreover, managed pressure drilling services are applicable in severe conditions, such as unknown pore pressure, differential sticking, high-temperature drilling, high-pressure, tight pore pressure, fluid loss, and various other conditions. The aim is to detect downhole pressure limits and manage the annular hydraulic pressure profile accordingly.

 


Managed pressure drilling services provide a proactive approach to well control, verifying downhole interruptions, enhancing primary well control, and automatically reacting to the influx. The success of Managed pressure drilling services is notified by good extraction activities in areas that are considered unconstitutional for production. The increasing energy demand and the decline in the production rate have increased the demand for managed pressure drilling services in many countries such as the U.S., the U.K., Italy, etc. worldwide. In the U.S., Weatherford unveiled new managed pressure drilling services at the 2019’s Offshore Technology Conference (OTC).

Moreover, Exceed (well management provider) acquired the U.K.-based Managed Pressure Resources (MPR), Lowestoft that delivers managed pressure drilling services to service companies, drilling contractors, and operators. The energy industry is beginning to realize the environmental and economic benefits of managed pressure drilling services. Over 40% of drilling problems occur during offshore operations, significantly increasing non-productive drilling time, as well as cost. Because of the high risk of complex drilling environments and the constant need to maintain energy security, operators are now focused on adopting advanced technologies such as managed pressure drilling that provide safety benefits.

Increasing Initiatives to Digitalize the Healthcare Sector Is Expected To Boost Demand for Electronic Medical Records

Image
  An electronic medical record (EMR) is essentially a systematized collation of individual patient and family health information in an electronic format. This information is then shared across several health care locations. This will save time, money and provide patients with more comprehensive care. Increasing initiatives to digitalize the healthcare sector is expected to boost demand for EMR. For instance, in November 2019, Germany introduced Digital Supply Act to digitalize healthcare. Under the new legislation, doctors will be able to prescribe digital health apps to patients, which can be reimbursed by the country’s statutory health insurance. There are several advantages to using EMR. The main advantage is that you do not need to wait for the paper records to go through the paper processing before you can use them. Another advantage to electronic medical records is that they allow for greater privacy. Electronic health records allow only the doctor to see these...

Ureteroscopes are highly preferred option over traditional ureteroscopy

Image
  Ureteroscopes are instruments that have been designed to allow doctors (including surgeons) to look inside the reproductive organs. This is done by passing a thin, lightweight tube through the cervix and up to the vagina. Once there, the tube makes a turn inside the uterus and exits via the fallopian tubes. The purpose of this excursion is to look for problems in the uterus or ovaries, which can cause infertility or hormonal imbalance in women. They are able to find many problems that other instruments might miss. One of the most common uses for such device is when doctors make the very first ultrasound images of pregnancy. The Ureteroscope is able to detect whether or not the fetus is progressing normally through the maternal birth canal and is able to help determine the health of the mother's uterus. Doctors also use these devices when they make the first "cavity" ultrasound images of a woman's abdominal cavity, looking for problems that could be c...

Pharmacy Benefit Management is an Integral Part of the Medicare System

Image
 Drug costs are rising and contribute altogether to add up to wellbeing consumption around the world. Since 2014, physician recommended drug costs have expanded by 33%. In 2020, worldwide spending on physician endorsed drugs is required to be US$ 1.3 trillion. Expanding drug costs and customer spending on physician endorsed drugs are expanding the interest for the pharmacy benefit management framework. The framework is worked by outsider heads who go about as a connection between drug makers, protection suppliers, and drug specialists. The framework helps with diminishing medication costs by haggling with drug producers and retail drug stores.    The individuals who are tried out different wellbeing plans and those without protection can get the benefit of the pharmacy benefit management framework. The framework gives prescriptions at a lower cost than those accessible at retail drug stores. To decrease rising wellbeing costs, Japan intended to begin evaluating drug cos...
