Q

Free Fluid Test

A

ability to prevent fluid separation. The problems this can cause are water loss, channeling, gas migration. 1.4% is the maximum allowed by Halliburton standard.

Q

Fluid Loss Test

A

Test the ability to retain water in the slurry. Nitrogen is pumped into a slurry sitting on a 320 mesh screen. Volume and time for the nitrogen to make its way through is calculated into formula. Bad fluid loss tests can change the densities, volumes and cause bridging, Fluid loss is one of the worst things to have.

Q

Rheology Test

A

Tests for slurry’s plastic viscosity at different sheer stress levels. It also tests for frictional properties and yield points.

Q

Thickening Time Test

A

Done using the High Pressure High Temperature tester. Uses temperature, pressure and time to determine when the slurry is no longer pumpable at 50bc.

Q

Compressability Test

A

Certain additives like Gas Stop and Super CBL liberate Gas from the slurry. The reaction should happen before the cement goes static. This test measures the time that reaction will happen.

Q

Static Gel Strength Test

A

Two Tests. Zero Gel Time and Transition time. Zero Gel time is when the slurry reaches 100 lb/ 100ft2. The Transition time is the time it takes from zero gel time to 500lb. Once this number is hit, the slurry no longer transmits hydrostatic on the rest of the slurry.

Q

Best Practice - Spacers and Flushes

A

Cleans the wellbore and removes the mud cutting and filter cake. Aids with the bonding process of cement. Separates incompatible fluid. 10 Minutes of Contact time or 1000 ft of annular fill.

Q

Best Practice - Top and Bottom Plugs

A

Bottom and top plugs are recommended on all primary casing jobs. Bottom plug after the spacer. Caution should be used when using a high amount of LCM because it could be plugged off.

Q

Best Practice – Rat Hole

A

If the rat hole is large enough, a viscous pill should be placed to keep the cement from mixing with mud.

17
Q

Best Practice - Centralization

A

100% Standoff is recommended but 70% minimum.

18
Q

Best Practice - Flow Rate/ fluid velocity

A

Turbulent flow is ideal whenever possible. Pump as fast as possible to aid in the most efficient displacement. Maximize sheer stress on well.

19
Q

Circulation - Best PRactice

A

2 full volumes or when no cuttings in well conditioned mud returns consistently to surface.

20
Q

Mud Fluid Loss Properties - BP

A

decreasing the filtrate loss into the permeable zone enhances the creation of a thin filter cake. That is created by a low fluid loss system.

21
Q

Pipe Movement - BP

A

One of the single most influential factors in mud removal. Reciprocation or rotation mechanically breaks up gelled mud and changes the flow patterns in the annulus which improves efficiency.

22
Q

Wait time BP

A

Must hold the slurry static until it gets into the plastic state. The time dependent liquid must have enough time to undergo the hydration process. If drilling comes too soon, there may be problems like changes in the density, dilution settling, gas migrations, bridging.

23
Q

What is the number one problem

A

Mud displacement best practices. failure of mud displacement which can lead to not only a cement job with less than ideal compressive strength but also to failure of zonal isolation.

24
Q

5 Key displacement factors

A
  1. Mud Conditioning (circulation before which washes away filter cake and hole cuttings. 2 whole volumes are recommended)
  2. Mechanical Aids. (Scratchers and cement baskets which reduce hydrostatic pressure)
  3. Centralization
  4. Fluid Velocity
  5. Spacers which is an enhanced fluid to push mud out of the way while flushes are a chemical reaction to clean the well bore.
25
Q

ECD

A

Equivalent Circulating Density = Hydrostatic gradient + friction gradient

26
Q

HDF Stands for?

A

Halliburton Delivery Framework

27
Q

What is the purpose of Battle Red

A

More flexibility for an evolving business environment.

28
Q

BD’s Role in HDF

A

Uses the information in HDF to prepare quote, proposal and well information during the proposal phase.

29
Q

What is Click Scheduling

A

Easy to use web based scheduling tool that optimizes and assists with coordination of scheduling and assigning resources to jobs. Increases visability of resources to the organization and drives better use of resources to the completion process.

30
Q

10 life rules

A

Driving, Working at height, work permits, confined spaces, PPe, Lock out tag out, chemicals, lifting, hand tools, dropped objects
