Dry Hole Explained in 6 Common Questions and Answers


A dry hole is a term used to refer to any well that does not contain oil or natural gas in quantities sufficient enough to pay for the cost of drilling the well in the...

The Numerous Functions of the Drilling Fluid


The drilling fluid faces a risk of contamination each time it embarks on its journey downhole. All these tend to change the properties of the drilling fluid.

How Hydrocarbon Reservoirs Are Formed: The Rock Cycle


Rocks are constantly being changed from one igneous to sedimentary to metamorphic. The oil and gas industry is most concerned with sedimentary rocks because hydrocarbons...

Grasping the Concept of Rock Permeability


In this friendly introduction to the concept of rock permeability, we discover how tiny pores within the rock allow fluids such as oil, water, and natural has to pass...

The Different Ways of Perforating a Well


Well perforation is a critical aspect of well completions. They provide a path of communication between the reservoir and the wellbore as the trapped hydrocarbons will...

Oil well hydraulic fracturing fracking rig in a field.


Fracking is projected as a menace despite proving its worth as an excellent drilling technique to increase shale production. In this article we discuss the positives of...

Steps to a Successful Field Appraisal


After striking oil and/or gas in an exploratory drilling, the field appraisal answers questions including how big the reservoir is and if the hydrocarbons trapped in...

Artificial Lift: When is it Needed?


No matter how much initial energy the reservoir has, there will come a point where the reservoir pressure drops to where the well dies. Artificial lift, such as sucker...

Mobile Offshore Production Units vs. Floating Production Storage and Offloading Units: What's the Difference?


Upstream offshore operations deploy complex oil rigs in different configurations depending on the nature of the oil field and type of operation. Mobile offshore...

Sweet vs. Sour Crude - Production and Processing


Crude characteristics play an important role in refining operations. They decide the type of refinery configurations required for processing, investment outlay,...

Upstream, Midstream, Downstream: A Look at the Petroleum Industry


The petroleum industry is broadly classified into three sectors - upstream, midstream and downstream. This article looks at each of these three sectors in terms of their...

Three Types of Oil Reservoirs


Understanding the kind of oil reservoir we are dealing with helps us make the best decisions to efficiently produce the hydrocarbons in the reservoir.

The Significance of Biogenic and Thermogenic Gases in the Energy Space


Thermogenic gases are part of the conventional gases and have major role in meeting the energy needs of the world.

Understanding Reservoir Drive Mechanisms


Any method of recovery must recognize the rock and fluid properties and available drive mechanisms present in the reservoir. As we search for hydrocarbons, we need to...

The Significance of Porosity to Original Hydrocarbon in Place


After a successful hydrocarbon discovery, the decision to complete or not will rest on how commercial the discovery is. To determine this hydrocarbon potential, the...
