Drilling Chemicals: Ensuring Safety and Efficiency Latest Advancements in Oil & Gas Operations

Drilling fluids, also known as drilling muds, play a pivotal role in rotary drilling operations by performing important functions such as removing cuttings from the wellbore, cooling and lubricating the drill bit, maintaining well pressure control and protecting potential productive formations against damage. The most commonly used drilling fluids are water-based muds (WBM), oil-based muds (OBM) and synthetic-based muds (SBM). Each type of mud is engineered using a carefully selected blend of chemicals to attain the desired physical properties needed for effective well control and optimum drilling performance. Chemical Components of Drilling Chemicals Drilling Chemicals muds derive their essential characteristics from the variety of soluble and insoluble chemical additives that are incorporated. Weighting agents like barite are added to control and maintain downhole pressure. Dispersants such as lignite and lignosulfonates help suspend the drilled cuttings in the circulated mud. Viscosifiers including bentonite clay and polymers create sufficient viscosity and gel structure needed to lift cuttings to the surface. Surfactants are added to reduce mud-solid interactions and improve shale inhibition. Fluid loss control agents prevent the loss of mud into the formation pore spaces. Biocides eliminate bacteria growth that can degrade the mud. Other important additives are pH control agents, lubricants, defoamers and corrosion inhibitors. Application of Drilling Chemicals The precise formulation of drilling muds depends greatly on the geological conditions expected in the well. For example, WBMs tend to be preferred for shallow water and inland areas where toxicity and environmental concerns are less stringent. They are cheaper and simpler to formulate but have lower performance compared to SBMs or OBMs. OBMs, apart from providing excellent lubricity, are suitable for drilling salt sections and highly-reactive shales. However, their use entails challenging environmental management and oil spill contingency planning. SBMs bridge the gap by offering enhanced shale inhibition and lubricity at lower costs relative to OBMs. They use synthetic solids and high performance additives to achieve properties on par with expensive OBMs. Shale Inhibition Challenges One of the major headaches faced while drilling is shale instability, which can easily lead to wellbore collapse, stuck pipe or lost circulation episodes. Maintaining wellbore integrity in shale formations requires drilling fluids formulated specially to arrest fluid invasion and suppress clay hydration/swelling. However, inhibiting reactive shales chemically without damaging drilling operations or formations remains an ongoing challenge. Mud chemists closely monitor filtration rates and rheology changes to ensure the protective filter cake deposited inside the wellbore does not penetrate deep into the formation. High performance shale inhibitors based on potassium/ammonium salts, lignite dispersants or resinous polymers have revolutionized shale drilling over the last decade. Solids Control is Critical An effective solids control system is indispensable for recycling drilling fluids after removing drilled cuttings. Cutting accumulation increases viscosity and density, reduces fluid properties and transportation abilities. Common solids control equipment in use include shakers, centrifuges, mud cleaners and dryers. Chemical conditioning aids like flocculants improve the effectiveness of these systems. Drilling fluid maintenance through monitoring, testing and chemical adjustments protects the drilled hole conditions as well as drilling fluid performance throughout the well. Proper disposal of mud and cuttings residues as per local environmental regulations is also essential.

So we’re getting a Chris has turned to shoplifting for attention (cry for help) arc aren’t we?!

That Helena thinks she’s being a good ‘parent’ and helping him bully giving him freedom and all these distractions like a pool etc but not actually giving him what he needs - therapy and to actually deal with his trauma and pain and she’s probably making it worse by basically placing herself as a good ‘mother’ to him - when the loss of Shannon and seeing Kim is what is central to his pain - she is disconnected from reality and what Chris needs.

So he’s maybe using chess club as a front in the same way science club was when he was sneaking to the park with his friends when he’s hanging out with these friends who aren’t actually friends - they’re a bad crowd - but they’re giving Chris attention and an actual distraction from his trauma. Which winds up with him shop lifting and getting caught - and he is in shop jail and calls Eddie for help rather than Helena or Ramon (or Eddie is there in some other capacity like he’s ended up as mall security or something!!).

Which leads to an Eddie and Chris conversation and also to Eddie asking Buck for help/advice via FaceTime - setting up coparenting buddie - which is a low key set up for Eddie’s feelings arc down the line a bit. It also leads to an Eddie and Helena conversation and a few home truths being dealt with - (eddie feeling invisible!) Eddie is then in a place to process and move through his grief and on with his life - which leads to resolution with Chris and ultimately also with Helena (because this is 911 and she is meant to be a representation of his mind so forgiving her is Eddie forgiving himself!) before a return to LA!!

Hiya! I love your writing and I'm so glad to be seeing you on my dash bc I haven't in a while! For your writing revival game, can I suggest:

"Incandescent" and either Ushijima or Osamu?

hi cheesy! 🥹 this is so nice of you to say, thank you 🥹 i've been a bit on and off here and there over the past few months because work has just been so busy 🥺 but i'm glad to be back here too!! thank you for sending in a prompt 🥹

contains: established relationship, halloween outfits, miya dynamics

osamu + incandescent

there are a lot of reasons why atsumu loves you for his brother―you bring osamu food when he barely has time to eat in the shop, and you send picture updates in the group chat you have with the two of them and ma. you also give him your extra onigiri when osamu says he's had too much.

you're there for osamu in times when he can't be, and for that, he's grateful.

this time though, he thinks he might just be indebted to you.

"people're g'na ask ya to sit on me," osamu glances at your costume before staring at the mirror again. from the dining table across the room, atsumu is holding in his laugh, doing his best to keep the water in his mouth.

tonight is onigiri miya's annual halloween party, and you've managed to somehow convince osamu to dress as a burner―red incandescent light and all.

"so i will," you smile sweetly, adjusting the foam handle of your outfit. the theme for the party is: onigiri miya, and truly, what is more essential to the shop than an electric burner and its pan?

from the side of the room, you think atsumu nearly chokes.

"it'll be cute," you step towards him, reaching for the black switch along his hip, "plus, you even light up!"

in an instant, he glows red, the spiral pattern along his chest lighting up like an electric burner heating up. atsumu snorts, erupting into a fit of laughter as he slaps his knee.

"shit," he wipes a tear while holding up his phone camera, "can't wait f'ma to see this."

osamu looks at him from the mirror, deadpan, "yeah, show'er ya shitty dye job too."

because atsumu doesn’t look any better at all, dressed as none other than osamu for halloween―black long sleeves with an apron, a pair of gloves and osamu's actual work pants. the cap on top of his head rests on temporarily dyed jet black hair, but he's done it in such a haste that his blonde roots are still showing.

you laugh, never quite getting used to their antics despite being a witness to it for years. halloween with the twins is always a memory you look back on fondly, and you don't think this year will be any different at all.
