Insurance Claim

Posted on 4/16/13 by Pat Maloney

When you’ve been in a car accident, you’ll likely need to file a claim with either your insurance company or the other party’s in order to recoup costs for your car repairs, medical bills, and other expenses incurred. These are called first party and third party insurance claims.

However, how do you know which type of claim you should file for your wreck? What can you expect with each type? Learn more about filing a car accident claim below.

Third Party Insurance Claims

A third party insurance claim is one filed with the insurance company of another driver involved. If the accident was the fault of another driver, even only partially, you will need to file this type of claim. Through a third party claim, the other driver’s insurance will cover the costs of your car repairs and damages or, in the event your car is totaled, provide you with the actual cash value of the vehicle.

If you were injured, the insurance company will likely offer you a settlement amount to cover your medical costs. It’s best you discuss any settlement offers with a qualified attorney before accepting.

First Party Insurance Claims

A first party insurance claim is one filed with your personal insurance company. If you’re involved in any accident, even if it’s not your fault, you may file this type of claim. If the accident is your fault, your insurance will help cover your costs, as well as costs the other driver may have suffered during the course of the wreck. If the other driver was at fault and their insurance doesn’t pay all of your repair or medical bills, your first party claim may help you cover them.

Additionally, if your car was stolen, vandalized, or otherwise harmed, you would also file a first party claim, and your personal insurance company would compensate you for the damages and repairs per your policy agreement.

Cutting slip velocity is velocity of cutting that naturally falls down due to its density. In order to effectively clean the hole, effect of mud flow upward direction and mud properties must be greater than cutting slip velocity (settling tendency of cuttings). Otherwise, cutting will fall down and create cutting bed.

You can learn more detail about it via this topic -> Cutting Slip Velocity

This calculation will show annular velocity, cutting slip velocity and net velocity so you can use as a reference for you hole cleaning indication. There are 2 calculation methods and I will show the first method via this topic.

1. Determine annular velocity with following equation:

Where;

AV is annular velocity in ft/min.

Q is flow rate in gpm (gallon per minute).

Dh is diameter of hole in inch.

Dp is diameter of drill pipe in inch.

2. Determine cutting slip velocity with following equation:

Where; Vs is cutting slip velocity in ft/min.

PV is plastic viscosity in centi-poise.

MW is mud weight in ppg.

Dp is diameter of cutting in inch.

DenP is cutting density in ppg.

3. Determine net rise velocity with following equation:

Net rise velocity = AV – Vs

Where; AV is annular velocity in ft/min.

Vs Cutting Velocity in ft/min.

This figure indicates that cuttings are being lifted by mud or are still falling down. If net rise velocity is positive, it means that you have good flow rate which can carry cutting in the wellbore.
On the other hand,If net rise velocity is negative, your current flow rate is NOT engough to carry cuttings.

Example: Please use the following information to determine annular velocity, cutting slip velocity, net rise velocity, and tell us if the flow rate is good for hole cleaning.

Information

Flow rate = 300 gpm

Hole Diameter = 6.3 inch

Drillpipe OD = 4 inch

PV = 15 cps

MW = 10 ppg

Diameter of cutting = 0.20 inch

Density of cutting = 20.0 ppg

1. Determine annular velocity:

AV = 310.3 ft/min

2. Determine cutting slip velocity:

Vs = 35.4 ft/min

3. Determine net rise velocity with following equation:

Net rise velocity = AV – Vs Net rise velocity = 310.3 – 35.4 = 274.9 ft/min

Conclusion: This flow rate is GOOD for hole cleaning practice because annular velocity is more than cutting slip velocity.
