Separator sizing and droplet sizes low shear school - 2017Low Shear School
The document discusses different methods for sizing three-phase separators, including retention time theory, droplet settling theory, and fluid carryover specification combined with estimated droplet size distributions. The droplet settling method calculates the separator dimensions based on the cut-off droplet diameter to be separated, while the fluid carryover method is more complex and utilizes inlet and outlet fluid quality specifications along with estimated droplet size distributions. Maintaining larger dispersed phase droplets upstream of the separator can improve separation efficiency by reducing retention time and fluid carryover.
This document provides an overview of basic well control procedures including:
- Kick detection and control methods like primary prevention and secondary detection and control
- Shut-in procedures such as hard, soft, and specialized shut-ins
- Well kill procedures including calculating initial and final circulating pressures, the wait-and-weight/engineer's method, and providing an example pump schedule.
It describes the key objectives and considerations for safely controlling a well when kicks occur and bringing the well pressure to a controlled state.
The document discusses enhanced oil recovery (EOR) methods, focusing on steam injection. It defines EOR as techniques for extracting more crude oil from reservoirs beyond primary and secondary recovery methods. Steam injection is a thermal EOR method that involves injecting steam into reservoirs to lower oil viscosity and produce more oil. There are two main steam injection techniques - cyclic steam stimulation (also called huff-and-puff) which alternates between steam injection and production from single or multiple wells, and steam flooding which continuously injects steam into reservoirs to displace oil towards production wells. The document outlines some advantages and disadvantages of steam injection and economic considerations.
This document discusses drilling engineering and hydraulics. It covers topics such as mud weight planning, pore pressure prediction, fracture gradients, and drilling hydraulics concepts like hydrostatic pressure. Maintaining the proper mud weight and hydrostatic pressure is important for well control and avoiding drilling problems. Both too low and too high of a mud weight can cause issues like wellbore instability, lost circulation, or differential sticking. The document recommends following the median line concept and making gradual changes to mud weight.
This document provides equations to calculate various drilling parameters such as bit pressure drop, nozzle velocity, hydraulic horsepower, impact force, torque, and mechanical specific energy based on inputs like flow rate, mud weight, bit diameter, weight on bit, and rotation speed. The equations can be used to determine values for nozzle area and velocity from flow rate or pressure drop, as well as calculate impact force, cross flow velocity, specific energy, coefficient of friction, and minimum flow rate.

Master class presentation on artificial lift screening and selection. Prepared for Praxis' Interactive Technology Workshop on Artificial Lift, Dubai, September 2013.
Safety is the most important factor in designing a process system. Some undesired conditions might happen leading to damage in a system. Control systems might be installed to prevent such conditions, but a second safety device is also needed. One kind of safety device which is commonly used in the processing industry is the relief valve. A relief valve is a type of valve to control or limit the pressure in a system by allowing the pressurised fluid to flow out from the system.
This document discusses the key calculations involved in a kill sheet for plugging and abandoning an oil well. It explains that a kill sheet is used to determine well parameters like volume, strokes, time, mud weights, and circulating pressures. It provides step-by-step worked examples of calculating strokes, times, kill mud weight, initial and final circulating pressures, and a step down chart. The calculations allow operators to safely pump heavy kill mud into the well to displace the drilling fluid before cementing and abandoning the well.
1. Hydraulics is important for drilling operations to remove cuttings, balance pore and fracture pressures, and prevent wellbore collapse. It becomes more critical for HPHT and extended reach wells with small pressure margins.
2. Key components of the circulating system include the drill pipe, annulus, casing, open hole, drill collars, mud pump, mud pit, and drill bit. Pressure losses occur through these components and must be calculated and balanced against pore and fracture pressures.
3. Proper mud weight and viscosity are needed to provide adequate hydrostatic pressure and hole cleaning while avoiding fracturing. The equivalent circulating density accounts for both mud weight and pressure losses.
Selection of the best artificial lift systems for the well depend on location, depth, estimated production, reservoir properties, and many other factors. Here is an overview on selection criteria for the best results

This document summarizes a wax deposition study on the Ravn oil field production system. It found that:
1) Wax deposition could reduce pipeline flow area and cause blockages. The study modeled wax deposition risks in the Ravn infield and export lines.
2) For the infield line, up to 4mm of wax could deposit at the seabed and 13mm at topsides within 30 days without inhibitors. Inhibitors could reduce this by 40%. Pigging was recommended every month without inhibitors and every 45 days with.
3) For the export line, up to 4mm of wax could deposit at the seabed within 22-31 days depending on inhibitors. Higher flows increased deposition risks

This document summarizes the key steps in designing liquid pipelines according to API 14E standards. It discusses important considerations like ensuring velocity is below 15 feet per second to avoid erosion and pressure drop is below 1 psi per 100 feet. The document then provides an example calculation for sizing a water pipeline using schedule 40 and 80 steel pipes. It determines that an 8-inch schedule 40 pipe meets both velocity and pressure drop requirements and has the lowest annual operating costs.
This document discusses various water-based mud systems used in drilling operations. It describes the basic systems commonly used like lignosulfonate systems and calcium treated systems. More complex systems are used as conditions change with increasing well depth, temperature and pressure. Factors that influence the choice of mud system include the application, geology of the formation, make-up water quality, drilling parameters, potential drilling problems, and rig equipment limitations. The document provides details on specific mud systems like potassium chloride PHPA mud, silicate mud and their components and applications.
This document discusses the design and operation of oil and gas pipelines and storage facilities. It covers key equations for calculating gas flow rates in pipelines, including the Weymouth, Panhandle A, and Modified Panhandle equations. Examples are provided to demonstrate how to use these equations to determine pipeline diameter and pressure drop given flow rates, temperatures, pressures, and other parameters. The document also addresses low pressure piping systems and provides equations for calculating pressure drop in plant piping.
This document discusses different types of thermal enhanced oil recovery (EOR) techniques. It begins by introducing EOR and explaining that thermal EOR involves injecting heat into reservoirs to reduce oil viscosity and increase flow. The main thermal EOR methods covered are steam flooding, hot water flooding, and in-situ combustion. Steam flooding generates steam at the surface and injects it underground, using it to heat oil and create an artificial drive toward production wells. Hot water flooding is similar but less effective due to lower heat content. In-situ combustion recovers oil by applying heat transferred to reservoirs through conduction or convection.
1. Gravel pack systems are used to control sand production in weak formations. Gravel is pumped into the annulus around a screen to block fine sand while allowing fluid flow.
2. The gravel pack assembly includes a packer, screen, blank pipe, centralizer, and bull plug. It is run in hole with the setting tool and packer. Pressure is applied to set the packer and release the setting tool.
3. Gravel slurry is then pumped through the work string, flowing out the window and filling the annulus around the screen. This blocks fine sand while maintaining production.
- The document describes an exercise to model and simulate oil production from the Harthun field to an existing platform called Wigoth Alfa via a subsea pipeline.
- The first task is to use steady state simulations at 5 kg/s and 15 kg/s flow rates to determine the minimum required insulation thickness and pipeline diameter. This will ensure the fluid arrival temperature is above 27C for 5 kg/s flow and pressure is below 80 bara for 15 kg/s flow.
- The document provides material properties, fluid properties, pipeline geometry and conditions to set up the preliminary steady state model and simulations in OLGA.
During a period of erosion and sedimentation, grains of sediment are continuously building up on top of each other, generally in a water filled environment. As the thickness of the layer of sediment increases, the grains of the sediment are packed closer together, and some of the water is expelled from the pore spaces. However, if the pore throats through the sediment are interconnecting all the way to surface the pressure of the fluid at any depth in the sediment will be same as that which would be found in a simple colom of fluid. The pressure in the fluid in the pores of the sediment will only be dependent on the density of the fluid in the pore space and the depth of the pressure measurement (equal to the height of the colom of liquid). it will be independent of the pore size or pore throat geometry.
This document discusses key properties of crude oil, including:
1) Oil is classified based on properties like specific gravity, viscosity, density, etc. with specific gravity and viscosity most commonly used. Specific gravity is represented by API gravity which ranges from 8 to 58 degrees.
2) Bubble point pressure is the pressure at which a small amount of gas is in equilibrium with oil. When pressure drops below this point, gas is liberated from the oil.
3) Other properties discussed include formation volume factor (ratio of reservoir to surface volumes), solution gas-oil ratio (amount of gas dissolved in oil), and compressibility (change in volume with pressure change).

Kesimpulan
12. Analisa Hasil Swabbing Job
1. Intial Fluid Level (IFL)
IFL = Swab Depth I – (Hasil dari swab-I : Tubing Capacity)
= 1.181 ft – (1.95 bbl : 0,0058 bbls/ft)
= 844 ft
2. Working Fluid Level (WFL)
WFL = Swab Depth Last – (Hasil dari swab terakhir : Tubing Capacity)
= 1968,8 ft – (3,9 : 0,0058 bbls/ft)
= 1.296 ft
3. Loads = Fluida dalam tubing + Fluida dalam annulus
• Tentukan Annulus volume
Annulus volume = ID Casing 7” – OD String
= 6,38 – 2,875
= 0,29 ann/ft
13. Analisa Hasil Swabbing Job
• Fluida dalam tubing
Fluida dalam tubing = (OE packer – IFL) x Vol tbg/ft
= (4.849 ft – 844 ft) x 0,0058 bbl/ft
= 4.005 x 0,0058
= 23,22 bbls
• Fluida dalam annulus
Fluida dalam annulus = Panjang Ekor “G” x Vol ann/ft
= 13 ft x 0,29 ann/ft
= 3,77bbls
• Fluida dalam casing
Fluida dalam casing = (interval bawah – ekor “G”) x Vol ann/ft
= (4.876 ft – 4.849) x 0,29 bbls/ft
= 27 ft x 0,29 bbls/ft
= 7,83 bbls
• Total Loads
Total Loads = Fluida tbg + Fluida ann + Fluida csg
= 23,22 + 3,77 + 7,83
= 34,82 bbls
