Ralph H. Lang Jr. and Associates

Mission

Ralph Lang is a licensed professional Geologist working in the Permian Basin. His company’s mission is to “Find water through the science of hydrogeology.” Ralph has hired a team of dedicated professionals and taught them the value of presenting their work according to the highest standards of integrity. A stated goal of Ralph’s team is “Success by Design.”

Wireline Logging

Wireline Truck

Wireline Truck

We have a one ton, four wheel drive wireline truck, that can travel off-road to log wells that are inaccessible to most vehicles. Our wireline truck has a hydraulically operated drawworks with 5,000 feet of cable. We have many logging tools that are great for mapping shallow water well formations.

Water Exploration

cross section

Water Exploration

Water well completions and electric logs from oil wells are gathered and serve as a basis for mappings and cross sections. A cross section is built using gamma ray logs from existing wells. This tool aides us in understanding subsurface features and stratigraphy. Dealing with the occurrence and distribution of underground water. We have a experienced and dedicated staff that research well reports, well logs from the subsurface library and the Texas Water Development Board database.

Well Testing

Well Testing

We can provide pump test graphs that model depth in feet, below ground level over elasped time in minutes. This will give you important information such as; the static water level, the average pumping rate, and the maximum draw down during testing. You can also see the rate of recovery, after the pump has been turned off. We perform our pump tests with a data logger transducer that provides real time readings of the static water level, pumping level and recovery. We also perform field water quality analysis with parameters that include, Temperature, PH, ORP, Conductivity, TDS, SPC and more.

E Log Tool

E Log Tool

The multi-parameter E Log Tool is primarly used for logging water wells and monitoring wells. The following are the parameters it can record in one pass: Natural Gamma Ray, Spontaneous Potential, Single Point Resistivity, 16 inch Normal Resistivity, 64 inch Normal Reisistivity, Fluid Resistivity and Temparature.

Full Wave Sonic

Full Wave Sonic

The Full Wave Sonic tool has a single transmitter and a dual receiver to record formation travel times. The full wave form data is also recorded simultaneously, along with near and far travel times, borehole compensated delta time, calculated sonic porosity, receiver gains, near/far amplitudes and natural gamma.

Three Arm Caliper

Three Arm Caliper

The Three Arm Caliper Tool is used for measuring the borehole diameter, natural gamma and fluid resistivity. The Three Arm Caliper can be used to log both open and cased holes. The Three Arm Caliper can be run after the Full Wave Sonic to verify there are no "washouts."

Gamma Ray Casing Collar Locator

Gamma Ray Casing Collar Locator

The Gamma Ray and Casing Collar Locator tool records natural gamma and casing collars. It's slim design allows us to log through drill pipe. This will save rig time from tripping out of the hole.
