PRD Interim – June 2021

MD DESK

Hello folks, its time to get our head in the game. Now that the wave of a shocking proposition is ending. We are allowed to focus on what we are to do during the coming months. The year is still young even though we have lost a few months it is time to regroup has a team and chart down the targets for the coming month.

I appreciate all the volunteers front line worker and our fellow members for the participation in helping the sick during ravaging COVID 19. Thank you one and all.

That’s being said it is nice to know that the stock has been pile up for us to execute with precision we shall. We have to continue to set our personal best records in exports and also in domestic and move towards the layer picture of achieving a sustainable growth in terms of sale figures. As always our focusing living on customer quality and delivery. All the best to the production teams best of luck.

We should continue to be vigilant about the pandemic and not easy on taking the necessary precaution. Stay safe and put on your mask always.

INTERNATIONAL NEWS - SUITABLE PRIME MOVER

The African terrains and infrastructure are getting better as innovative developments are produced by the new governments. However, some rural regions still require equipment on suitable prime movers to access drilling sites.

The management of Horizon Drilling (a specialized drilling company based in Nakuru County, Kenya) knows this very well having experience using a PRD Max Drill on a Sino Howo 290HP truck for several years now. The success performance reports of their first unit has necessitated the growth of their company by having an additional PRD Max Drill, (to cater for their ever-growing customer needs).

The choice of the second PRD Max Drill (mounted on a Sino Howo 371HP truck – FIRST EVER 6X6 TRUCK FOR A MAXDRILL SOLD IN EAST AFRICA), has been a consultative effort of the PRD Rigs Kenya team and that of Horizon drilling, in selection of the prime mover, design, compressor, and mud pump choices, tools and accessories, were all detailed in the purchase plan meetings.

The superb assembly of the drilling rig has been a talk of the industry after it was unveiled in Kenya recently for its well-designed features; Being a 6×6, improved access to the site over tough terrains, and ample hydraulic power for drilling operations. It also has improved safety features i.e emergency switches for the rig and drives incorporated into the control panel.

The PRD Rigs Global MD Mr. Paranthaman, was in Nairobi, Kenya for the handover ceremony where he handed to Horizon Drilling’s representative, the keys for their new unit, and further, had in depth discussions on Horizon’s performance in the market and their achievements over the years. Along with the MD was the Regional Director for East Africa Mr. Saravanakumar, who gifted the customer with various goodies and momentous.

WHAT’S NEW IN THE FACTORY - WAGNER 52 PERFECT FLOW

New painting gun has been purchased for our painting department to have rapid application of paint over the metal surface when compared to the traditional paint guns. The new paint gun has been coupled with double diaphragm pump for a consistent perfect flow of the paint to the gun. This reduces the wastage in atomizing the paint, inconsistent flow or excessive air pressure to the gun will result in the wastage of the paint. This gun eliminates the paint container on the gun which reduces the weight of the gun significantly which enables the painter to paint the surface in a fast pace. This also helps the painter to paint easily the overhead / underneath surfaces.

After implementing the new gun time study has been taken to monitor the actual values for the implementation of this new painting gun. The detailed study is as follows

Hence this painting gun will save lot of time and increase the painting finish to global standards and also makes our painting booth adhere to the latest technologies and equipment to save time and cost.

TECHNICAL CORNER - DRILLING FLUID FUNCTIONS

As noted above, the principal function of drilling fluid is to clean the hole of cuttings, but there are several other purposes:

– Cool and clean the bit: keeping the bit cool, especially if it has elastomer seals, is critical to its life.
– Lubricate the drill string: this can be a significant factor in deviated (non-vertical) wells, where the drilling string is lying against the wellbore wall.
– Maintain the stability of the borehole: the proper drilling fluid can help control swelling or sloughing formations, thus lessening the risk of stuck drill pipe. It is also important that the fluid hold the cuttings in suspension when circulation is stopped, so that they do not fall back and pack around the bit and BHA.
– Allow collection of geological information: the cuttings brought back to the surface by the fluid help to identify the formation being drilled.
– Form a semi-permeable filter cake to seal the pore spaces in the formations penetrated; this prevents fluid loss from the wellbore.
– Control formation pressures: if high downhole pressures are present or expected, dense material can be added to the drilling fluid to increase its specific gravity, thus resisting the downhole pressure.  Conversely, if low downhole pressures pertain then lower density drilling fluids may be used to minimize formation damage and reduce differential sticking pressures in particular.
– Transmit hydraulic horsepower: this power can be used for driving a drilling motor or for cleaning the hole and/or the bit.

DRILLING FLUID SYSTEM

It should be emphasized that the drilling fluid is part of a circulating system, comprising the fluid itself, the mud pumps, and mud cleaning equipment. The pumps must have sufficient capacity (flow rate and pressure) to provide adequate bottom-hole cleaning, high annular velocity to lift the cuttings, and enough hydraulic horsepower to drive downhole motors and provide the designed pressure drop through the bit jets.

When the cuttings-laden mud returns to the surface, it passes through a series of devices to remove the cuttings.  The first of these is usually the shale shakers, which have tilted, vibrating screens that filter out larger cuttings and let them slide off into collection containers; next are usually hydrocyclones (Figure), which use fluid inertia to swirl the

fluid in a conical chamber, letting the solids drop out the bottom; and finally, centrifuges spin the fluid to extract the finest particles through their density difference.  Effective mud cleaning is important for drilling performance as well as cost control.  If the fluid has to be discarded because of inadequate cleaning, it is expensive both in material cost and in time loss.

DRILLING FLUID PROPERTIES

The drilling fluid will be designed to have certain properties, and it is critical to monitor and control these properties at all times.  Design and maintenance of drilling fluids is a complex topic, covered in great detail in many sources44,45 but primary attributes of fluid for a given well include the following.

Viscosity: it is vital that the fluid’s viscosity be high enough to lift cuttings out of the hole as the fluid circulates, and to hold the cuttings more or less in suspension when circulation is stopped.

Density (or specific gravity): if formation pressures are expected to be high, then the fluid can be weighted to help control them but, as is often the case in geothermal wells, if formation pressures are low, then the fluid should be as light as possible to avoid lost circulation.

pH: the alkalinity of the fluid is important for corrosion control, rheological properties in bentonitic mud, and for its reaction with certain formation constituents; normal pH is 9.5 to 10.5, but higher values are not uncommon.

Filter cake: this is a measure of how well the fluid forms an impermeable layer on the borehole wall to prevent leakage into the formation’s natural permeability. (This is typically more important in oil and gas drilling than in geothermal.)

Solids content: this is a measure of how well the mud is being cleaned, and can also determine when the mud should be discarded or diluted.

Successful mud systems need at least these three attributes:

Stability: The desired properties of the fluid, once established, should be stable under normal drilling conditions and temperatures.

Easy treatment: If the desired fluid properties are lost, treatment should be available to restore them.

Property testing: Tests and testing equipment should be available to identify fluid properties at the temperatures in the well and indicate any treatment required.

TECH FUTURE - THE AGE OF AI

Artificial Intelligence (AI) is all about Exploring Identity, Creativity and Collaboration between humans and machines.  It’s advancing faster and taking less time to be widely adopted than ever before. Roughly it took 10,000 years to go from writing to printing press but only 500 more to get to email. It seems we are at the dawn of a new age, the age of AI (Artificial Intelligence).

AI is a wide-ranging tool that enables people to rethink how we integrate information, analyze data, and use the resulting insights to improve decision making—and already it is transforming every walk of life.

From transportation to healthcare, financial services to robotics, manufacturing and more, artificial intelligence – more simply known as AI – is making a tremendous impact on the way people around the world live and do business.

According to market research firm IDC, spending on AI technologies is projected to reach USD 52.2 billion by 2021, creating strong economic growth opportunities around the globe. To help unlock the promise of AI and remove barriers to its adoption, globally relevant and globally accepted voluntary consensus standards are key. The standards community has been up to the task, collaborating across industries and national borders to drive innovation.

In the next four years, we expect AI’s industry growth will start to explode and its impact on business and society will begin to emerge. By 2030, increasingly useful applications of AI will translate into meaningful social and economic changes.  One such outcome, for example, will be much lower costs of traditional goods and services, which will effectively narrow socioeconomic disparities worldwide, as AI eliminates imperfections in supply chains and enhances overall productivity.

As automation takes over decision making on a daily basis, the next generation of managers with AI Leadership skills will have to take up higher level responsibilities involving the human aspects of decision making such as innovative thinking, employee development, and bridging the gap between technology and people. It also means that business leaders have much to gain with the advent of AI.
